Pump water centrifugal water cannon. Submersible pumps Dzhileks Vodomet for wells and wells

Diameter

I think many will be interested to know more about the submersible pump Vodome, I will give you this opportunity in the form of a question - answer. There is little experience in answering these questions, questions were asked by our customers and after which this article about Vodomet pumps was compiled.

Question: Where is the multistage submersible centrifugal pump Vodomet (hereinafter Vodomet) used?

Answer: The water jet pumps water from a well, a well, from open water sources and delivers water through pipes for further use. Suitable for organization automatic system water supply in country house and for irrigation.

Question: What is the design of the submersible multi-stage centrifugal pump Water cannon?

Answer: The water jet has a hydraulic part and an electric motor. The hydraulic part has impellers, diffusers and shafts, while the electric motor has a stator and a rotor. Water is taken from the bottom of the pump, water enters through small filter holes. The water cannon is completed with a special cable and plug for connecting to the mains.

Question: How minimal inside diameter should there be a supply line in submersible pumps Vodomet?

Answer: The value of hydraulic resistance depends on the diameter of the supply pipe, the smaller the diameter. the higher the resistance. Minimum Diameter supply pipe for all submersible pumps must be at least 1 '' - 25 mm. When the diameter is narrowed and the flow through the pump is less than 10 l.min. you risk overheating the pump and it will burn out.

Question: What is the minimum depth of the Water Cannon in the water?

Answer: The pump can be lowered to a minimum depth of 15-20 cm from the suction side of the pump.

Question: What does the buyer need to know about, which is not always discussed during the sale, if a submersible pump supplies heavily polluted water when pumping a well for the first time?

Answer: When the pump pumps heavily polluted water, it is forbidden to turn it off, otherwise its impellers can simply jam due to sand settling from the pressure pipe. He should be allowed to work. The pump can be turned off only after clean water comes out of the line. In the process of pumping a well with a Vodomet pump, the pump pumps water with a high content of sand, sand can exceed the norm several times, which means that there is a high probability of wear of anti-friction washers. After pumping the well, I recommend to make Maintenance pump by contacting a specialized service center.

Question: What ensures a high throughput of impurities among domestic and even imported domestic submersible borehole pumps?

Answer: This is achieved by "floating" impellers and increased axial and radial clearances. It is due to this feature that the pump is able to pass through itself up to 2 kg of impurities per 1 m³ of water.

Question: How long can the water jet pump run continuously?

Answer: The pump can be operated in continuous mode, the pump is cooled by the flow of water pumped through itself.

Question: What is the maximum number of starts allowed per hour for the Vodomet pump?

Answer: The maximum number of inclusions is no more than 20 inclusions / hour.

Question: Is it possible to use the pump Vodomet 60/52 A in a well?

Answer:Submersible pumps A water jet with the index "A" is used only in wells, tanks or open water. It is not advisable to use it in a well, since the pump with the “A” index is equipped with a float electric valve to turn the pump on and off as water enters. A pump with a valve may simply not fit into the well.

Question: Where to locate and why you need a mechanical check valve on the pump?

Answer: The non-return valve is installed no more than 7 meters from the pump or directly on the pump. I recommend installing an additional check valve at the accumulator to reduce water hammer in the water supply system.

Question: What should be the minimum allowable distance of the intake part of the pump to the bottom of the well or well?

Answer: The distance must be at least 1 meter.

Question: What is the minimum volume of the accumulator to be installed autonomous system water supply using a water jet pump?

Answer: The volume of the accumulator must be at least 50 liters. But the accumulator can be selected and accurately using the formula. Provided that you know the maximum volume of water that you will consume (Amax liters / min.), As well as the power of the submersible pump, knowing these parameters, you can supply water, using the table, select the appropriate volume of the accumulator Vt. Or use the calculator -

Vt- this is the volume of the tank, liters;

A max– maximum volume of consumed water, liters/min.;

Pmin- the minimum pressure at which the pump starts;

P max- the maximum pressure at which the pump is switched off;

R pres- initial pressure in the tank;

TO- coefficient corresponding to P pump power.

The pressure values ​​in the table are expressed in bar.

Question: Do I need a stabilizer for the Waterjet pump to work? How to choose the right stabilizer?

Answer: The stabilizer equalizes the voltage in the mains to the nominal value of 220-230V. A voltage stabilizer is selected based on the power of the submersible pump. The pump power is multiplied by the factor "3", the power of the required stabilizer is obtained.

For example: The power of the submersible pump "Vodomet" 60/92 is 1100W * coefficient "3" = 3300 watts.

You will need a voltage stabilizer with a power of 3500 watts.

Question: I want to increase the length of the pump cable, will it be necessary to increase its cross section, why?

Answer: By increasing the length of the cable, it is also necessary to increase its cross section, because when you increase the length of the cable, the voltage drop on the pump itself also increases.

Selection table for electric cable section

Question: How are centrifugal, vibrating and vortex pumps different?

Answer:

• Centrifugal pumps has a long service life, high throughput on impurities (sand) and high efficiency.
• vibration pump reduces the life of the water supply source (well, well), it breaks aquifers, well walls, wells, has elevated level noise, short lifespan, and poor performance.
• vortex pump combines the properties of centrifugal and volumetric machines, so the vortex pump provides high efficiency. Nevertheless, this type of pumps is characterized by a change in efficiency over time, because the hydraulic part of the pump has small axial and radial clearances. After the ingress of impurities (sand), the wear of its working surface reduces the flow-pressure characteristic.

Question: I'm going to cut the pump's plug, will the warranty still be valid?

Answer: If it is necessary to cut the electrical cable, for example, it is necessary to pass the electrical cable through the head or simply lengthen it, in this case the warranty remains valid. Be sure to use a heat shrink sleeve to connect the electrical cable.

Wiring diagram for a submersible multistage centrifugal pump Vodomet

Do you have a water pump? Everything suits me? Write in the comments about the experience of using this pump.

The Russian company "Dzhileks", located in the village of Klimovsk, Moscow Region, produces submersible multistage pumping units. Water cannon pumps are manufactured to provide independent water supply to a private house and garden watering. Moreover, the range of equipment of this brand is represented by a whole set of household appliances that have different power and dimensions. Thanks to such a large selection, the buyer can choose a model that provides the required amount of water.

All submersible pumping units of the Vodomet series are manufactured at domestic enterprises, therefore, even at the development stage, parameters are laid in them that allow the equipment to be adapted to work in the conditions of domestic water supply systems. This is especially important, since our waterways are not as clean as foreign ones.

Downhole pumps of this series are able to pump even dirty water with impurity content up to 300 g per m³. For the production of guides and impellers, the manufacturer uses a special LEXAN polymer. And for the manufacture of thrust bearings, ceramics and graphite are used. Thanks to such innovative additions, the wear resistance of the units increases, their service life increases, and the likelihood of breakdowns is minimized.

At the same time, downhole units of the Dzhileks brand are practically not subject to clogging, since they have a self-cleaning function. It is not surprising that such pumps can only be heard about positive reviews, because in addition to domestic nodes, they use parts of American, French, Swedish, German and Italian production.

The performance and design of pumps of this brand are constantly being improved. For example, new models are distinguished by the fact that the electric motor in them is located above the pumping part. This made it possible to reduce the dimensions of the housing, as well as connect the electrical cable to the upper part of the unit.

Advantages of water jet pumps

Submersible pumps of this brand have whole line advantages over similar models from other manufacturers. Thanks to them, they have earned numerous positive reviews. Among the advantages of these units are the following:

• The borehole and well pump of the Dzhileks brand works very quietly, which is important for country houses and dachas.
• Compact dimensions allow you to choose a unit for any well size.
• Unlike vibration models, submersible pumping units of the Vodomet series do not create turbulences in the water that raise silt and sand from the bottom.
• Acceptable cost, since the pumps are of domestic production.
• High performance and efficiency.
• The units can work even in dirty water containing sand, silt or clay within 2-5 kg/m³.
• Due to the washed motor (water circulates between the stator shell and the unit housing), the electric motor is effectively cooled.
• Another significant advantage is the use of two separate sealing parts in the design. They not only protect the electric motor from high pressure, but also ensure its tightness and separate oil filling of the internal parts.
• In models of the PROF series, the membrane and seal are protected (this function is not provided in other units).

Important to know: pumps must be lowered into the shaft of a hydraulic structure on steel cables. This is the only way to be sure of the reliability of fixation.

Varieties

All pumps of the Vodomet series can be divided into two types:

• well unit;
• borehole pump.

Dzhileks brand well pumps are suitable for use in relatively shallow structures (8-10 m). They can also be used in open reservoirs and various water tanks.

The main condition for the operation of such a unit is sufficient dimensions of the tank, well or reservoir. The thing is that it is necessary to install not only the pumping unit there, but also the float switch.

Many reviews say that the Vodomet well pump differs from the downhole unit in a number of advantages:

• The efficiency of such a device is much higher. Consequently, submersible pumps for wells with the same technical characteristics will give greater productivity than similar downhole equipment.
• They are less sensitive to dirty, silty or sandy water than well pumps.
• In such models, it is not necessary to use protection against operation in the absence of water, since there is a simple float switch.
• The price of such units is in the range of $ 90-130, which is lower than the cost pumping equipment for wells.

Models

Submersible pumping units of the Vodomet series are produced in various modifications. All of them are different technical parameters and power. Usually the marking of pumps of this brand looks like this - 55/50A (there may be other combinations of numbers). The letter designation "A" indicates that the pumping equipment is equipped with a float switch that produces automatic shutdown in the absence of water. The numbers in the designation indicate such characteristics:

• The first number is the flow rate of the pumping equipment at the outlet. It is measured in l/min. This value is determined with fully open taps, in conditions where there is no resistance to the movement of water.
• The second number is the maximum head that can be reached with fully screwed taps. Measured in meters.

Based on the marking, we can draw the following conclusions about the operation of units of various modifications:

1. Deep pumps 60/32 with a flow rate of 60 liters per minute will work more efficiently in water intake facilities with a small debit. At the same time, the performance of the hydraulic structure should not be lower than the performance of the pumping equipment. Otherwise, the pump can quickly pump all the water from the water intake and will work "dry". This can lead to failure of the unit.
2. A device marked 60/52 can provide water consumption of 35-40 liters per minute (more than 2 m³ per hour). This is equal to four faucets open at the same time.
3. A Gilex brand pump marked 60/72 with a similar water flow will provide a stronger pressure. Such units allow you to move water over longer distances, so they are suitable if the source is away from home.
4. The 115 liters per minute borehole pump is suitable for use in medium to high production wells. In this case, the debit of a hydraulic structure can be about 4 m³ per hour. Submersible pumping equipment model range 115/115 is one of the most powerful devices. The power of such pumps reaches 2200 kW.
5. For water supply of multi-storey buildings, it is better to use units with a flow rate of 150 l / min. They can only be installed in hydraulic structures with high performance. It is also better to use them when the water flow is more than 4 m³ per hour.

How to choose?

Of course, you can make a choice of a Water Jet pump model based on customer reviews, but it’s still worth doing a simple calculation yourself. To determine the required pressure of pumping equipment, it is necessary to take into account the required pressure in consumer taps. It is important not to forget about possible pressure losses in the pipeline, as well as the height difference between the consumer and the source.

• if this value is less than 5 m, then you can use a pumping unit with a pressure not higher than 35 m. Submersible pumping equipment Vodomet 55/35 is suitable for this purpose;
• if from the water mirror to the earth's surface within 5-25 m, you can buy a pump with a pressure of 40-50 m, for example, a pumping unit Vodomet 60/52;
• at a distance of 25-45 m, it is better to use a model with a pressure indicator in the range of 60-75 m. For these purposes, a submersible device Water cannon 60/72 is suitable;
• if from the water surface to the top of the earth 45-60 m, it is better to choose more powerful units with a pressure from 90 to 150 m. The device of the 115/115 model range will cope well with this task.

Operation and possible breakdowns

Since pumping equipment is completely submerged in water, it works in extreme conditions. Despite constant improvement, the pump can fail. The most common causes of breakdowns can be such phenomena:

• If the installation and use of the unit was carried out without following the recommendations and instructions of the manufacturer, then there is a high probability of a breakdown.
• Voltage fluctuations in the network can lead to the failure of pumping equipment.
• If the unit is constantly pumping very dirty water with a high content of sand particles, this will accelerate its wear and failure.

Important: a guarantee of a long service life deep pump – correct installation in a hydraulic structure. At the same time, the diameter casing pipe must be at least 100 mm. The unit must be completely submerged in water, but no more than 1.5 m from the bottom of the water intake.

To protect the well from foreign objects, the upper part of the casing string is closed with a special cap. To prevent freezing of water in winter period a caisson is constructed above the upper part of the casing, and the pipeline is connected and laid to the house at a mark located below the freezing point of the soil.

Pumps of the Vodomet series are lowered into the well, suspended on a strong cable, to which it is attached on the sides power cable and a water hose. The rope is securely fixed at the top.

In order to ensure uninterrupted operation of water production, it is necessary to install special equipment. Pumps Dzhileks Vodomet for pumping water, you can install with your own hands near the mouth of a source of drinking or technical water.

In addition, Dzhileks Vodomet pumps for pumping water from a well can be immersed under the surface of the water table. This one is able to extract the required volumes of water from a do-it-yourself well and supply it to the house, outbuildings, greenhouses or gardens.

1 What is the design of Dzhileks Vodomet pumps?

The Gileks Water Jet pump for water extraction is presented in the form of a multi-stage unit, the principle of operation of which is based on the active use of centrifugal force. All Dzhileks Vodomet pumps for pumping water are equipped with floating wheels and a washed motor. A do-it-yourself unit can reliably supply water from:

• reservoir;
• open reservoir;
• Wells.

Due to the presence of floating wheels, the Dzhileks Vodomet pump for pumping water has enough high rates hydraulic efficiency. Reviews about such a pump, for the most part, are only positive.

The technical characteristics of the Jilex Vodomet devices are quite high, this is also evidenced by user reviews. Thanks to a number of design improvements, the Dzhileks Vodomet pump has a fairly compact axial dimensions of the body and a low weight of all rotating working elements.

The consequence of all this is a significantly reduced level of vibration of the unit during its operation. In addition, it will not be difficult to disassemble such a pump with your own hands and repair it.

The use of floating wheels in the pump contributes to the minimum number of blockages that occur due to the ingress of large particles into the system.

In addition, the electric motor of the pump is well protected against sudden overheating. The characteristics of the device allow washing the engine with a stream of water in order to cool it.

In addition, the presented pump can be installed in the well with your own hands. Repair of this unit can also be done by hand.

Feedback on the installation of the pump with your own hands and how it was repaired will help you figure out how to properly carry out the procedure for such work.

The engine is located above the pumping part of the device. Such a feature constructive solution allows you to output the power cable directly from the .

Thanks to this, the pump can be mounted in a well with a minimum working diameter, and it can be easily repaired if necessary.

It should be noted that the presented layout of the pump has proven itself well in cases where the design is used and when it is partially submerged.

The unit itself consists of two main parts - this is the engine and the pump compartment, which is located in a common housing. All other moving parts and elements of the unit are centrally fixed in the housing using a special intermediate support.

It also uses the front and back covers. The pump is designed in such a way that the floating wheels included in it can approach each other.

Due to this, there is a significant reduction in the gap between the parts of the device that are in a movable state and the fixed parts.

This solution avoids the occurrence of internal leaks and, in general, has a positive effect on increasing the efficiency of the entire system.

All presented units, depending on the types of marking, have a different number of repeating steps. All parts in the device are divided into four subspecies. This:

1. Impeller.
2. Cup.
3. The bottom of a glass.
4. Anti-friction washer.

The glasses are made in the form of cylinders made using black polyamide. Each of them is equipped with a belt that rests against the ring.

The ring is inserted into the spacer located in the body. An anti-friction washer is located between the glass and the impeller; it is designed to prevent friction of the mechanism parts.

The whole system is based on the rotation of the impellers located in the glasses. The cylinders are fixed and do not move due to the fact that they are fixed between and the cover.

1.1 Types of models

All units are divided into three main categories. These can be pumps for extracting water from a well; a special cooling jacket is supplied with such devices.

In most cases, the systems are used in the arrangement of private houses or summer cottages. Downhole type units are used to provide water supply from those wells that have a large diameter.

In addition, such pumps are used in all kinds of tanks and reservoirs. Chastotnik type systems are widely used in areas where uninterrupted water supply is required in automatic mode.

As a rule, these are cottages and suburban areas. An important advantage of such a device is the ability to provide the desired level of pressure in the entire water supply line.

The pressure level is not affected by the number of points from which water is drawn. Feedback on pumps is mostly positive.

1.2 Specifications and reviews

Here are some specific parameters of the most common models.

2 The most common malfunctions and their repair

One of the most common unit malfunctions that require repairs is that when the device is turned on, the pump does not pump water.

If you listen carefully, you can sometimes hear a barely noticeable buzz. Sometimes the device does not make any sounds at all and can be shocked at the moment when the user touches its case.

All these signs indicate that there was a partial abrasion of the covers located between the stages and the impellers. In order for the unit to work again, it must be completely disassembled and worn out impellers and covers must be replaced.

In addition, another cause may be a faulty capacitor. In such cases, the incorrect operation of the device is due to the ingress of water through the cable passage into the cavity of the capacitor compartment.

A faulty capacitor is subjected to mandatory replacement. In the event that when the start button is pressed, the pump does not turn on, first of all, you should make sure that there is voltage in the electrical network.

First of all, the integrity of the cable, which provides power to the unit, is checked. It happens that the control panel of the device fails.

In this case, it is almost impossible to make repairs on your own. Here you will need the help of a qualified specialist.

You should also act if protection is often triggered, which is activated in the event of a breakdown of the power cable and leakage of electricity.

If during start-up the device turns on, but does not pump water, check that the valve is installed correctly.

In this case, the pump must be lifted out of the well and make sure that the valve is installed properly. Sometimes it happens that an air lock forms inside the unit.

To eliminate it, it is necessary to immerse the pump to a greater than usual depth. In this case, the valve is installed at a height exceeding 1 meter.

Another reason for such a problem may be improper installation and installation of a check type valve. In this case, the pump is also removed and the check valve is reinstalled.

If, when the system is turned on, a partial supply of water is produced and its pressure constantly weakens, then, most likely, the equipment was operated without turning off for quite a long time. The reason for the low pressure is a clogged cleaning filter.

If it is clogged, the filter is disassembled and cleaned. Otherwise, it is completely replaced.

During the intake of water, the pump in some cases gets a large number of sand. In such a situation, the unit is placed in a container with water and it is pumped.

In order to avoid such moments in the future, you need to take care of installing an additional cleaning filter. If the equipment has completely stopped pumping water, then first of all the unit should be de-energized and removed from the well in order to conduct a detailed inspection.

With such a breakdown, the cause may be a significant decrease in the water level in a well or well. It is necessary to immerse the pump to an even greater depth.

In some cases, equipment jamming occurs. Often this is observed with severe contamination of all channels. If it is not possible to eliminate the cause with your own hands, then you should contact a qualified specialist or a service center.

Each well in the summer cottage for supply from the depth pure water, must be equipped with a device such as a water jet pump. This device, like a water jet pump, makes it possible to receive water from a well where there is no water.

Powerful specifications water cannon pumps allow you to lift water from great depths. The water jet pump is small in size, has a very simple design, and endowed with the simplest automation.

1 Features and differences

Water jet pump "" regardless of size, models are always made only at domestic enterprises. All pumps of this line are adapted to the Russian climate. And we know that water resources(highways) have never been clean in our country.

As a result of this, even the simplest water cannon can pump the dirtiest water and not fail for a long time. The channels inside the pump are practically not contaminated.

The most important advantage of the pump is that it is able to clean itself. Pumps are also good because, in addition to Soviet components, you can easily pick up spare parts for them from French, American and even German production. At the same time, the price of a water jet pump is much lower than, for example, German or French counterparts.

Now the pump is constantly being improved. The quality of performance is improving, the design has become an order of magnitude better. Here, for example, if we talk about the latest model of a water jet pump for a well, then in it the electric motor is located above the location of the pumping part. As a result, the Water Jet water pump has a body that is an order of magnitude smaller. It became possible to connect electrical cable to the top.

All water jet pumps for wells have a wetted motor. This means that water passes between the casing and the stator sheath. As a result, the engine is continuously cooled.

The water jet pump for the well has high-quality dividing seals. These seals protect the motor and also give a complete seal to the housing.
