Tal electric ets 3200 operation manual. Instructions for labor protection during the operation of manual and electric hoists

  • 04.03.2020

With correct calculations, the electric hoist can withstand a double load. But this does not mean that you need to operate it at full capacity. It is necessary to strictly adhere to the mode of operation indicated in the passport of the mechanism.

During the installation, the work of the workshop is stopped. A preliminary check of the technical condition of the overhead track is carried out. The monorail track must be grounded. If there is none, the craftsmen must zero the non-current-carrying metal parts. The ground wire must be a different color to distinguish it from the power wire.

You can mount an electric hoist on a monorail track in any part of it. But if the device is not installed from the end, it is necessary to disassemble the carts. You can also remove the hook suspension and the switch panel for more convenient performance of all work. After mounting the trolley hoist, the panel and hook are reassembled and mounted on the lifting mechanism.

After the hoist is mounted on the monorail, it is connected to the mains. After connecting all cables, check. The hoist hook must move in the direction indicated on the switch. The correct connection of the phases is determined by the position of the rope layer. It should stay in the middle of the drum.

If you want to use the hoist in an open area where there is no power supply, then an alternative would be hand hoist.

Preparation for commissioning

The hoist must not be put into operation immediately after installation. The whole mechanism must be checked and debugged. First, a visual inspection is performed, during which:

  • the reliability of all connections and the oil level are checked;
  • the operation of starters and switches is configured;
  • electromagnet, ring current collector and brush holder are checked.

At the first start of the mechanism, the load is not given. The operation of the hoist is checked, the brake system is adjusted, the stop button is checked. If everything functions properly, the nominal load is applied to the hook. With a positive result and confirmation that the installation of the hoist was made correctly, the mechanism is put into operation.


The most important tasks in the operation of electrical equipment are to maintain all electrical and electromechanical components in working order. During the operation of electrical equipment, it is necessary to exclude the failure of all component electrical and electromechanical parts of this equipment. And conduct regular inspection of electrical equipment and make periodic diagnosis of all constituent parts which may fail during operation. Operation of electrical equipment is a set of preparation and use of products for their intended purpose, Maintenance, storage and transportation. Main tasks of operation

electrical equipment in agriculture - to achieve uninterrupted, reliable and high-quality power supply to all agricultural production facilities, to create normal operating modes for electrical equipment that ensure its best technical and economic indicators, to increase the reliability of equipment operation. The main task of the operation of electrical equipment is to maintain it in good condition throughout the entire period of operation and ensure its uninterrupted and economic operation. To accomplish this task, it is necessary to carry out scheduled maintenance of electrical equipment. During the operation of electrical equipment, its technical condition deteriorates due to wear, breakdowns, violations of adjustment, loosening of fasteners. Even a minor malfunction, such as an unreliable contact in an electrical machine, can lead to electrical equipment failure, and in some cases, to an accident. Maintenance allows you to timely identify and eliminate faults that occur during operation, or causes that may lead to a malfunction.

"Inspection of electrical equipment"

Permanently operating power equipment requires systematic systematic inspection by qualified personnel. Inspections are carried out according to the schedule and in accordance with the instructions approved by those responsible for the operation of the electrical facilities. During inspections of switchgears, all comments are recorded in the log of defects and malfunctions, brought to the attention of the managers of the power company, who take appropriate measures to eliminate the identified violations as soon as possible. Regular inspections of switchgears without turning off the equipment are carried out at the following times: at facilities with a permanent duty officer - once a day and at least once a month in the dark to check for the presence of discharges.

"Electrical Equipment Repair"

The main duties of employees of energy enterprises serving electrical facilities are: ensuring uninterrupted power supply to consumers, reliable operation

equipment and networks, maintaining the required frequency of the electric current, ensuring maximum efficiency of the energy enterprise for the rational use of energy resources, production efficiency, transmission and distribution of energy. To maintain power equipment in good technical condition, systems of scheduled repairs have been developed and are being applied, since during operation, electrical equipment wears out and becomes obsolete. Depreciation of electrical equipment, by its nature and the reasons causing it, is conditionally divided into mechanical, electrical and moral.

Mechanical wear under the action of friction or as a result of corrosion is subjected to moving parts and parts of electrical equipment "contacts of apparatus, parts of the mechanism"

“PPR Scheduled Preventive Repair System” The PPR system, depending on the operating modes of electrical equipment and the conditions of its operation, establishes the alternation, frequency and volume of maintenance and repairs of electrical equipment, taking into account ensuring the uninterrupted operation of the enterprise and safe work. Scheduled preventive maintenance includes maintenance work, overhaul maintenance and current and major repairs of electrical equipment. Carrying out repairs of electrical equipment, provided for by the PPR system, reduces the cost of its maintenance, reduces the number and time of downtime, the number of accidents, increases the reliability of work and the quality of repairs. The organization of repair and maintenance of equipment at the enterprise can be carried out centrally and decentralized. The centralized system is characterized by the fact that the repair of electrical equipment is carried out by specialized repair services, and the maintenance and minor repairs of electrical equipment in operation are performed by personnel subordinate to the corresponding production unit "service, section". With a decentralized system, there are no specialized repair services and all repair work, such as maintenance, minor repairs and maintenance of equipment, is carried out by the personnel of workshops, services, teams of the direct production site.

Current repairs are carried out to ensure the operability and reliability of the equipment until the next scheduled repair. With this type of repair, work should be carried out to inspect electrical equipment, clean, seal, adjust and repair individual blocks and parts with the elimination of defects that have arisen during operation.

During scheduled repairs, it is necessary to pay great attention to operational personnel who have group 3 access to electrical installations. When repairing an electric motor, it is necessary to de-energize it and make sure that the electrical equipment is not energized. Visually inspect this engine for damage, chips and other defects leading to engine failure. When disassembling the engine, pay special attention to the integrity of the bearings and lubrication. Bearing lubrication should be 75%, only in this case the motor can be used

4. Types of repair, their essence:

Maintenance- this is a scheduled repair, which ensures the normal operation of electrical equipment until the next repair by replacing or restoring worn parts of equipment, purchased products, as well as by carrying out preventive measures, adjusting mechanisms, and eliminating individual malfunctions.

At current repair electrical machines perform the following work;

Checking the degree of heating of the housing and bearings, the uniformity of the air gap between the stator and the rotor, the absence of abnormal noises in the operation of the electric motor;

Cleaning and blowing the motor without disassembling it, tightening the contact connections at the terminal boards and connecting wires, stripping the rings and collectors, adjusting and fastening the brush holder traverse, restoring the insulation at the lead ends, electric brushes;

Change and add oil to the bearings.

If necessary, produce:

Complete disassembly of the electric motor with the elimination of damage to individual places of the winding without replacing it;

Flushing of components and parts of the electric motor;

Replacing faulty slot wedges and insulating bushings, washing, impregnating and drying the motor winding, coating the winding with top varnish, checking the fan mounting and repairing it, turning the rotor shaft necks and repairing the squirrel cage (if necessary), changing flange gaskets;

Overhaul is a type of repair induction motor with a short-circuit rotor, in which the engine is completely disassembled, its parts or components are partially or comprehensively replaced, the repaired parts and the unit as a whole are checked, the stator windings are completely replaced, they are tested under load. Before the overhaul of the electrical equipment of the 16v20 screw-cutting lathe, a statement of the scope of work is compiled and a set of necessary spare parts, equipment, and purchased products is prepared.

During the overhaul, the following operations are performed: complete or partial replacement of the winding; straightening, rubbing the necks or replacing the rotor shaft; rotor balancing; replacement of the fan and flanges; complete soldering of cockerels; cleaning, assembling and painting the electric motor and testing it under load.

5. The procedure for the withdrawal of electrical equipment for repair:

When bringing electrical equipment 16v20 into repair, it is necessary to carry out organizational and technical measures. Organizational measures include: Filling out the necessary documentation, drawing up an application, issuing orders, compiling a defective statement, and training personnel.

Technical measures:

Disconnecting equipment from the network, taking measures to prevent "spontaneous" and erroneous voltage supply to workplace.

Posters and safety signs must be posted. Also install portable grounding, if necessary, fencing of the workplace.

Hanging prohibition posters: On the drives "handles of drives" of manually operated switching devices, "switches, knife switches, automatic machines" in order to avoid voltage supply to the workplace, posters "Do not turn it on! People are working" should be hung out. e - on fences. On the valves that block the access of air to the pneumatic actuators of the disconnectors, a poster "Do not open! People are working" is posted. Fencing the workplace, hanging posters: In electrical installations, posters "Grounded" should be hung out, if turned on by mistake, voltage can be applied to the grounded section of the electrical installation. For temporary fencing of live parts that remain energized, shields, screens, screens made of insulating materials can be used. Temporary fences should be marked with the inscription "Stop! Tension" or appropriate posters should be fixed. There are three forms of operation and repair of electrical equipment:

1) Centralized; 2) decentralized; 3) mixed. 1. Centralized - a form that can be used in most industrial enterprises. With this form, overhaul maintenance and all types of repairs of electrical equipment are carried out by a single repair unit for the entire enterprise: a repair team, a repair site or a repair shop, which is part of the chief power engineer's service. The centralized form has a significant advantage over other forms of organization of repair, as it allows you to concentrate in the repair unit specialized, repair and control and testing equipment, specialized repair personnel, a stock of backup electrical equipment, spare parts and materials, to carry out repairs in accordance with advanced technology using high-speed repair methods.

2. Decentralized - the form is used at enterprises with simple electrical equipment that does not require specialized repair and control and testing equipment for repair. With this form, maintenance and repair personnel are included in the staff of the main workshop. Repair of electrical equipment is carried out at workplaces or a repair shop located on the territory of the main workshop.

7. Drawing up a defective statement:

Defective statement - a document required when describing certain shortcomings, flaws and marriages found in certain material values. This document is required for quality control by the buyer or by the seller. There is no unified form of the defective statement, and any enterprise can draw up this document on its letterhead.

Defective statement - a document in which the malfunctions of the repaired equipment are also recorded.

The purpose of compiling a defective statement is:

1. Reducing the time of repair of electrical equipment of the hoist;

2. Improving the quality of repairs.

In practice, two types of defective statements are considered:

preliminary

9. Control and testing of EO, after repair:

Tests of electrical equipment must be carried out in compliance with the requirements of safety regulations and PTE.

It is allowed to measure the insulation characteristics of electrical equipment under operating voltage, provided that devices are used that ensure the safety of work and protect the normally grounded output of the controlled object from the appearance of dangerous voltage on it when the connection with the ground is interrupted.

Before testing the insulation of electrical equipment, the outer surface of the insulation must be cleaned of dust and dirt, unless the tests are carried out by a method that does not require disconnecting the electrical equipment.

Testing the insulation of the windings of rotating machines with an increased applied voltage of a frequency of 50 Hz should be carried out in turn for each electrically independent circuit or parallel branch (in the latter case, with complete insulation between the branches).

Change

KP 140448.14.4RE1.000 PZ
Windings that are tightly interconnected and do not have both ends of each phase or branch removed must be tested relative to the body without disconnecting them.

The test voltage should rise smoothly at a rate that allows visual control by measuring instruments, and upon reaching the set value, be maintained unchanged throughout the entire test period. After the required exposure, the voltage gradually decreases to a value of not more than one third of the test voltage and is turned off.

The duration of the test means the time of application of the full test voltage established by the standards.

10. The procedure for acceptance of electrical equipment after repair into operation:

Upon acceptance, the following steps must be taken:

Visual inspection; check the stator winding (for integrity, for a short circuit between phases; for a short circuit of the windings to the housing, for a turn short circuit.)

The presence of axial and radial play, which must comply with the standard value.

Connect the electric motor to the supply network for checking the engine in idle mode. At the same time, pay attention to extraneous noise, vibration and measure the value of the no-load current.

Acceptance of electric motors with voltages above 1000 volts, power transformers, high-voltage switchgear after overhaul and medium repairs is carried out by a commission chaired by the head of the electrical department or his deputy with an entry in the log of the withdrawal of electrical equipment for repair and commissioning after repair.

Acceptance from maintenance and overhaul of electric motors with voltage up to 1000 volts.

Acceptance of electrical equipment from a contracting repair organization is carried out by the foreman of the site for the repair of electric motors according to the act

acceptance of electrical equipment from repair.

The foreman of the site for the repair of electric motors makes entries in the passports of electrical equipment about the work performed, indicating defects in the statement.

Acceptance and delivery certificates with the application of technical documentation and a list of defects must be kept in the passports of electrical equipment.

Electrical equipment, electrical networks, networks, grounding put into operation after repair are tested in accordance with the volumes and standards specified in the rules technical operation consumer electrical installations. According to the results of the test, protocols are drawn up.

After preliminary acceptance from repair, electrical equipment is checked under load within the time specified by the manufacturer, but not less than 24 hours. If there are no defects in the work during this period, the commission accepts the electrical equipment for operation and establishes

assessment of the quality of the repair. If defects are found, the repair is not considered completed until they are eliminated and the electrical equipment is re-checked under load within the next 24 hours.

After repair, the electric motor is tested on a test bench in the workshop with the execution of an inspection certificate in the form. After checking, with positive test results, the electric motors are transferred to the technical workshop with the installation of a pumping station (another similar one) on the frame by the repair service of the electrical workshop in the presence of serviceable lifting mechanisms and free passages for transporting the electric motor. In the absence of lifting mechanisms or their malfunction over this electric motor, the installation of a pumping (other similar) unit on the frame is carried out together with the technological service of the workshop, on the balance of which this electric motor is located. Alignment of the electric motor with the driven equipment is carried out by the repair service of the technological workshop.

11. The use of modern devices, tools and technology in the operation and repair of EO:

As digital measuring instruments, the following are widely used:

1) Ammeter - a device for measuring current strength in amperes.

The scale of ammeters is graduated in microamps, milliamps, amperes or kilo amperes in accordance with the measurement limits of the device.

Change
Sheet
Document No.
Signature
date of
Sheet
KP 140448.14.4RE1.000 PZ
The ammeter is connected to the electrical circuit in series with the section of the electrical circuit in which the current is measured; to increase the measurement limit - equipped with a shunt (for DC and alternating current), current transformer (only for AC circuits) or magnetic amplifier (for DC circuits). A complete device from a current measuring head and a current transformer of a special design is called a "clamp meter".

2) Current clamp - a device for measuring alternating current without breaking the circuit in which the current is measured.

The principle of operation of current clamps is based on the fact that the current flowing in the wire creates a magnetic field around itself. If this field is variable, then, according to the law of electromagnetic induction, in another conductor covering a wire with current, an EMF arises, which under certain conditions is proportional to the measured current.

3) Voltmeter - a direct reading measuring device for determining voltage or EMF in electrical circuits. Connected in parallel with the load or power source.

4) Multimeter - a combined electrical measuring instrument that combines several functions. In the minimum set, this is a voltmeter, ammeter and ohmmeter. Sometimes a multimeter is performed in the form

current clamps. There are digital and analog multimeters.

A multimeter can range from a lightweight portable device used for basic measurements and troubleshooting to a complex, stationary instrument with many features.

The typical accuracy of digital multimeters when measuring resistance, DC voltage and current is less than ± (0.2% +1 unit of the least significant digit). When measuring AC voltage and current in

frequency range 20 Hz ... 5 kHz measurement error ± (0.3% + 1 unit of the least significant digit).

12. Fulfillment of the requirements of the safety and fire safety rules during the operation and repair of EO:

Safety regulations (TB):

Fulfillment of the rules of safety is mandatory without reasoning and amendments.

Safety rules are: unconditional and conditional; mandatory and recommended. Types and schedule of briefing:

1. Safety training and general briefing;

2. Briefing before starting work;

3. Instruction at the workplace.

4. Checking the briefing is always required.

5. In case of violation of TB, the requirements of TB take precedence over the requirements of work

At the entrance to production room there should be an inscription indicating its class for explosive or fire hazard.
Persons responsible for the state of electrical installations (chief power engineer, head of the electrical shop, engineering and technical worker of the appropriate qualification, appointed by order of the head of the enterprise or shop) are obliged to:
a) ensure the organization and timely conduct of preventive inspections and scheduled preventive repairs of electrical equipment, apparatus and electrical networks, as well as the timely elimination of violations of PTE and PTB that could lead to fires and fires;
b) monitor the correct selection and use of cables, electrical wires, motors, lamps and other electrical equipment, depending on the class of fire and explosion hazard of the premises and conditions environment;
c) systematically monitor the condition of protection devices against short circuits, overloads, internal and atmospheric overvoltages, as well as other emergency modes of operation;
d) monitor the serviceability of special installations and means designed to eliminate fires and fires in electrical installations and cable rooms;

electrical installations;
f) participate in the investigation of cases of fires and fires from electrical installations, develop and implement measures to prevent them.
The electrician on duty (shift electrician) is obliged to carry out scheduled preventive inspections of electrical equipment, check the availability and serviceability of protection devices and take immediate measures to eliminate violations that can lead to fires and fires. The results of inspections of electrical installations, detected malfunctions and measures taken should be recorded in the operational log.
Checking the insulation of cables, wires, reliability of connections, protective earth, the operating mode of electric motors should be carried out by the electricians of the enterprise both by external inspection and with the help of instruments. The measurement of wire insulation resistance must be carried out within the time limits established by the PTE and PTB.
All electrical installations must be protected by protection devices against short circuit currents and other emergency conditions that can lead to fires and fires.

13. Conclusions on the project:

In the process of working on a course project, I studied the types and nature of repairs, safety and fire safety rules. I studied the electrical equipment of the screw-cutting lathe and its components. I also paid special attention to the choice of diagnostic devices and the principle of their operation in the given values. The most effective, in my opinion, are digital diagnostic devices, such as: ammeter, voltmeter, megohmmeter, multimeter and frequency meter. The paper considers modern technologies repair work electrical equipment of machine tools of the turning group.

3. TECHNICAL DESCRIPTION

3.1. DESIGNATION OF ELECTRIC TELEPHERS

3.2. CLASSIFICATION OF ELECTRIC TELEPHERS DEPENDING ON THE LOAD MODE

Telphers are widely used in construction and industry for carrying out lifting and installation work. They are electrically powered devices that are powered by a motor and can lift loads weighing up to 10 tons to a certain height. Telphers are installed on single-girder overhead cranes or on a monorail track. The design of the equipment includes a movement mechanism, with the help of which the horizontal movement of the load is carried out.

The installation of the hoist must be carried out by a specialized organization or a qualified specialist with certain training. For the correct installation of equipment, it is important to consider the following conditions:

  1. lifting capacity and lifting height of the hoist;
  2. the speed of the mobile mechanism;
  3. beam profile parameters;
  4. conditions for the use of equipment;
  5. compliance of the electricity voltage with the requirements of the manufacturer;
  6. compliance of installation and connection with safety requirements.

Telphers, as a rule, are delivered in assembled form. Before installation, make sure that the mains voltage matches the parameters of the equipment. many kinds professional equipment work from an industrial power supply network, but there are also models for power supply from a conventional 220v network.

When choosing equipment, you should also pay attention to the beam profile numbers. The equipment passport indicates on what size tracks the equipment trolley can be installed. It is not allowed to use the hoist on beams with a profile smaller than indicated in the passport.

Before installation, it is important to carefully inspect the equipment.

  • It should be free of dust, dirt and moisture, so the hoist must be thoroughly cleaned, dried and lubricated in accordance with the requirements of the manufacturer.
  • It is necessary to check the serviceability of all bolted, contact connections and locking mechanisms.
  • An experienced electrician should check the condition of the wires and measure the insulation resistance.

The hoist is installed on the track using bolts and fastening strips, studs and a set of washers included in the equipment kit. The hoist must be positioned so that the distance between the trolley wheel and the rail is 4 mm on each side.

You need to make sure that nothing interferes with the movement of the cart. To do this, it is not recommended to paint the rail track, as the paint creates resistance. The lubrication of the track can also interfere with the progress of the trolley. In addition, the track must be regularly cleaned of dust and dirt, dried from moisture in order to avoid corrosion. The rail track must be free and the slope must be at least 3%. There are special safety requirements that the rail track must comply with. Below are some of them.

  • The distance from the hoist to the ceiling or to the lowest point of other equipment operating above the hoist must be at least 100 mm.
  • The distance from the hoist to the walls of the building or to the columns and railings is at least 60 mm.
  • From the bottom of the hoist to the floor or to another working platform - at least 2000 mm.
  • The distance from other equipment operating next to the hoist is at least 400 mm.

Telfer connection

It works from the mains, but before connecting it to the mains, you need to carry out a preliminary check.

  • All individual parts of the hoist must be inspected for rust. If there is rust on the brake wheels, engine cover and brake cover, the engine may catch fire after connecting the power.
  • It is necessary to check the reliable connection of the electrical unit. For this, an ammeter is used.
  • It is also important to check the phases by applying voltage. It is necessary to hang the hoist and, by pressing the control buttons, check the direction of movement of the hook and trolley.

Electric hoists are connected to the power supply according to a specific scheme specified in the equipment passport.

Important!

The mains voltage must match the parameters of the hoist. When choosing power cable It must be taken into account that voltage drops should not exceed 10%. The length and cross-sectional diameter of the cable must match the motor power of the hoist.

Safety requirements

The hoists must be operated by people who have full knowledge of the safety rules. In addition, specially designated people should regularly inspect the health of the equipment.

Before the first operation, the hoists must be tested with loads weighing 25% more than the rated capacity. The test should last a maximum of 10 minutes.

Warning Do not exceed the rated lifting capacity when working with hoists. In this case, all ropes, hooks must be of the appropriate carrying capacity. Failure to comply with safety rules is dangerous for the lives of nearby people and for the safety of the cargo.

The equipment passport should indicate how many times the hoist can be used within an hour. This requirement must be strictly observed in order to avoid overheating of the engine. When using a hoist, do not leave the load suspended. It is also not recommended to press several buttons at the same time. After using the equipment, it must be disconnected from the power supply.

Inspection of equipment should be carried out at least once a month. During the inspection, the following should be checked:

  • condition of all individual parts;
  • reliability of fasteners;
  • condition of the track;
  • brake operation;
  • condition of electrical wiring insulation, etc.

The results of the inspection should be recorded in the inspection log. All detected faults are subject to immediate repair or replacement.
