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 it goes out of the line pure water. 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 Vodomet with index "A" are 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 a hydraulic accumulator to install an autonomous water supply system using a Vodomet 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.

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.

Selecting a model of a submersible borehole pump Vodomet

Two numbers in its designation will help you choose the right pump model. The first number indicates the maximum flow rate in liters of water per minute at the outlet of the pump in the absence of resistance to water flow. The second number shows the maximum head in meters developed by the pump during dead end operation.

For example: the WATERJET 60/52 pump, with a free spout, delivers 60 liters of water per minute (3.6 cubic meters per hour), and when the supply is cut off, i.e. with closed water taps, it develops a pressure of 52 meters (5.2 atm.). In the limit mode, the pump is practically not used. It is most often operated at the so-called "working point", with a nominal (50% of maximum) flow at a nominal (50% of maximum) pressure. However, you can choose a pump according to the maximum parameters.

VODOJOT pumps with a maximum flow of 60, 115 and 150 liters of water per minute were developed on the basis of many years of analysis of average water consumption and the performance of water sources. VODOJOT pumps with a maximum flow rate of 60 liters of water per minute are designed for water supply sources (well, well, etc.) with a small and medium flow rate and with an expected moderate flow rate (2-3 cubic meters per hour or 35 - 40 l / min, t .e. 3-4 taps) with nominal water flow.

VODOJOT pumps with a maximum flow rate of 115 liters of water per minute are designed for water supply sources (well, well, etc.) with an average and increased flow rate and with an expected increased (3-4 cubic meters per hour or 50 - 65 l / min) nominal water consumption.

Pumps submersible water jet with a maximum flow rate of 150 liters of water per minute are intended for water supply sources (well, open reservoir, etc.) with a high flow rate and with an expected high (4-6 cubic meters per hour or 65 - 100 l / min) nominal water flow.

The maximum pump head should be selected depending on the vertical distance, from the ground surface to the static water level in the source:
- if this distance does not exceed 5 meters, you need a pump with a pressure of 30-32 meters;
- if this distance is up to 25 meters, you need a pump with a pressure of 45-52 meters;
- if this distance is from 25 to 45 meters, you need a pump with a pressure of 60-75 meters;
- if this distance is from 45 to 60 meters, you need a pump with a head of 92-115 meters.

Submersible borehole pumps Water cannon are not equipped with a built-in non-return valve, therefore, in some cases, it is recommended to install a non-return valve on the pump outlet. For example, when a pump is operating in an automatic water supply system for a pressure-controlled pump, a check valve maintains pressure in the system, preventing water from flowing out. Moreover, the check valve should be installed in the pressure line near the pump, since in this case it protects the system from hydraulic shocks, preventing the formation of voids in the pipeline.

A valve installed above 7 meters from the surface of the water in the source cannot prevent the formation of voids in the pipeline, and this leads to water hammer at the moment the pump is turned on. However, the installation of a check valve directly at the outlet of the pump, with a slight deepening of the pump under water, can lead to the formation airlock in the pump and the water will not reach the first impeller, which will lead to "dry run" pump. Therefore, with a slight (up to one meter) deepening of the pump, the check valve should be installed at a distance of 1 to 7 meters from the pump.

In the case of using the pump for filling containers or watering, when periodically removing the pump from the source, the check valve should not be installed, since the hose filled with water is not light in weight. However, care must be taken in this case, otherwise, after turning off the pump, water flows back through the pump and the hose works like a vacuum cleaner. Therefore, a hose dropped to the ground during a backflow can cause the pump to clog.

Water jet pump device

The pump consists of a pump part and a wetted electric motor, located in a single housing made of high quality stainless steel. The components are centered in the housing by means of front and rear covers, as well as an intermediate support. Pump motor oil-filled, sealed, asynchronous with squirrel-cage rotor on rolling bearings. A thermal protector is built into the stator winding to protect the motor from overheating. The motor seal is unloaded, as the pressure inside and outside the motor is equalized by the membrane, the maximum submersion depth of the pump under water is 30 meters. The pump motor is cooled by the pumped water, so the pump must not be allowed to run when there is no flow.

Design feature "floating" pump impellers "Water cannon" is their running-in. It is known that the gap between the rotating and stationary parts of the hydraulic part of the pump is the cause of internal leakage in the pump, which reduces its efficiency. Therefore, ensuring small gaps in a traditional pump is a difficult technological task. During operation, these gaps increase, which, accordingly, reduces the already low efficiency of the pumping stage of a traditional pump.

In the "VODOMET" pump, the impellers are "floating", as they have the ability to move in the axial direction, clinging, under the action of working pressure, to the rear surface of the guide vane (diffuser) of the previous stage. In this case, the contact occurs along one of the two pairs of rubbing surfaces. In the first hours of operation, the plastic shoulder of the impeller in the cover of the guide vane (diffuser) is intensively worn, while electricity consumption increases somewhat and the flow-pressure characteristic decreases. This wear and tear results in "lapping" collar, providing "zero" clearance. Then, unloading the first rubbing pair, the second pair of rubbing surfaces comes into contact. This is an anti-friction washer and a ceramic ring. Since the friction of these parts in water occurs without wear, and a "zero" gap has already formed in the zone of the sealing shoulder, the pump reaches the optimal operating mode. This mode is characterized by an increase in the flow-pressure characteristic and a decrease in electricity consumption.

All parts of the pump that come into contact with the pumped water are made of materials approved for contact with foodstuffs. In the rear cover of the pump with the outlet pipe, there are two lugs for fixing the cable. A water-resistant, hygienic cable of the required length exits from the rear cover of the pump, which reduces the risk of incorrect connection of the pump.

Pump with index "BK"- with cable length 1 m. Pump with index "BUT"(automatic) is equipped with a float switch that prevents the pump from running without water. Such a pump can be used in a well or other source that has enough space to use a float switch. An anti-friction sleeve is installed in the front cover of the pump, which serves as a support for the shaft of the pump part.
In the front cover of the submersible pump, there are suction windows 1.5 x 1.5 mm in size, which prevent the penetration of large particles into the pump.
In the front cover of the pump with an index "M"(main) a fitting is mounted, which allows the pump to be used as a surface pump built into the water supply line.
it is completed with a hydraulic accumulator, a control panel and the necessary shut-off valves that allow you to assemble.
Pump with index "H"(frequency converter) equipped with electronic system automatic control, which provides " smooth start» pump, protection against "dry running"(from the operation of the pump without water consumption) and the exact maintenance of the specified pressure in the water supply system, regardless of the flow rate.
