Water cannon pump: description and technical characteristics. Well pump Centrifugal water jet pump

Downhole pump by definition cannot be cheap. When working in a filter well, it is regularly exposed to particles of sand and silt, and water has to be delivered from artesian structures to a sufficiently high height.

In search of a reliable device at an affordable price, owners of private plots most often choose a water pump manufactured by Dzhileks. In this material, we will consider in detail the device and the principle of operation of the equipment, we will talk about the features of its selection and use.

Pumps "Vodomet" have a fairly wide range of applications. With their help, you can pump water from wells of various depths, as well as from wells and open reservoirs.

They perfectly cope with the autonomous water supply of a private house, are used for watering the site, garden, etc. In this case, the diameter of the well should be 100 mm or more.

The case is made of high quality stainless steel. The top point of the pump is sealed in such a way that during its operation sand and other contaminants do not enter the casing from above.

The pump motor is enclosed in a sealed glass filled with oil. This design eliminates Negative influence external factors and protects the engine from damage.

The design and dimensions of the “Vodomet” pump allow it to be installed in wells with a casing pipe with a diameter of 100 mm or more

The device is oil-filled, asynchronous, the motor rotor is squirrel-cage, mounted on rolling bearings. The motor is partially protected from overheating by a thermal protector built into the stator winding. In addition, an additional cooling factor is water passing through a special annular gap left between the housing and the motor stator.

To balance the external and internal pressure of the engine, a special membrane is used. This allows the motor seal to be unloaded. As a result specifications allow you to use the pump "Vodomet" at a depth of up to 30 meters. The top and bottom covers are arranged in such a way that all components of the device are in correct position about the central axis.

An important feature of the pump design is the presence of so-called “floating” impellers, which have the ability to run in. efficiency of traditional pumping equipment largely depends on the size of the gap that is formed between its moving and static parts.

The larger such a gap, the more internal fluid leakage occurs inside the device, and the lower its efficiency. During the operation of the pump, the moving elements are gradually erased, which increases the clearance, and the efficiency becomes even lower. The design of the "floating" impellers of the "Vodomet" pump gives them the ability to move in the axial direction.

Deciphering the markings of various models

The marking of the pump in the form of letter indices reflects the design features of individual models:

• "BK"– the cable length of this model is 1 m.
• "A"(automatic) - the presence of a float switch that prevents the situation of "dry running".
• "PROF"– pumps for wells without an automatic shutdown system.
• "M"(main) - equipped with a fitting that allows you to use the pump on the surface, as an element of the water supply system.
• "HOUSE"- additionally equipped with components for the organization of automated water supply of a private house.
• "H"- Availability electronic system automatic control pump.

Devices marked with the index “A” can be installed in wells or other structures where there is sufficient free space for mounting a float switch.

The Russian company "Dzhileks" produces equipment for the organization of water supply, heating and sewerage. Among the wide variety of products, a special place is occupied by pumps that pump water from underground wells, wells and open reservoirs. These products can be seen in large industrial and agricultural enterprises and in everyday life.

For example, a Dzhileks pump for a well will help organize the supply of drinking water to a private house or cottage. There is also equipment that will raise water from a deep well, and if necessary, you can use it to irrigate gardens.

The main feature of the equipment of a young and rapidly developing company is the use modern technologies, simplicity, quality and reliability. All pumps are fully adapted to the harsh conditions of the Russian climate and water composition.

Pumps are less expensive than foreign analogues, many components and components are Gilex's own development. Along with this, high-tech parts supplied from other countries are widely used, which are distinguished by high-quality technical characteristics. The presence of reliable automation can protect devices from damage in emergency cases.

The range of products impresses with its breadth and areas of application:

• pumps for drinking water;
• sewerage;
• pumping other types of liquids;
• irrigation of crop areas.

Dzhileks pumps for pumping water from a well

These units are mainly used for open water sources with a large area - wells, individual reservoirs and natural reservoirs. It is in such places that it is easier to pump water and place additional equipment in the form along with the pump. The electric motors of these pumps are protected from water ingress and contain a so-called cooling jacket. In private houses and cottages, they are used quite often.

The principle of operation of the float switch is simple - if the water level falls below a certain mark, then the float drops and opens the contacts of the pump motor. This ensures the safety of the product in such a situation.

Similar products are marked as follows - Water jet PROF 55/35 A, where the first digit 55 indicates the flow rate, measured in liters per minute, and the second digit indicates the pressure, which is also measured in liters. The letter "A" means automatic, that is, the use of a float switch. Depending on the design and diameter of the casing, the parameters of the pump may be different.

Advantages of pumps for wells:

• high efficiency;
• reliability and durability;
• low prices - from 7 to 11 thousand rubles, depending on the capacity;
• the ability to pump water with sufficiently large impurities and sand particles;
• the use of materials that do not impair the quality of drinking water.

Well pumps

They are centrifugal type devices with so-called "floating" impellers. They are used in deep sources of drinking water, and can also be used in wells. The case diameter of these products is 98 millimeters, made of high quality stainless steel, the electric motor is in an oil cup, which ensures its cooling and stability of operating parameters.

These units are used in wells with a depth of no more than 30 meters. They are powerful and high performance. There are pumps for marginal underground sources, where the amount of replenished water is small, and there are pumps for pumping large volumes of water.

Advantages borehole water cannons Gilex:

1. High efficiency, and hence good technical characteristics.
2. Using the principle of centrifugal force is more beneficial not only in terms of pump efficiency, but also saves the well itself. For example, vibration products, in addition to great noise, create soil vibrations, which can lead to the destruction of the well and its tightening with sand.
3. Ability to pump water with a high content of foreign particles.
4. Profitability.
5. Reliability and durability due to double protection of the product - from high water pressure and sealing of the electric motor.
6. Ease of maintenance and operation.
7. Prices are also very democratic - from 7 to 17 thousand rubles.

Water supply system "Chastotnik"

Submersible type pumps Dzhileks "Chastotnik" are designed to create an autonomous water supply with constant water pressure, mainly for residential buildings and dachas. And this is achieved by using a filling tank (hydraulic accumulator) with a control unit.

In fact, the principle of operation of these units resembles pumping station, with the only difference that it is used on the surface, and the submersible pump is at depth. At the top there is only a hydraulic accumulator and a control unit that controls and controls the operation of the electric motor, a system for maintaining a given level of water pressure.

Many people ask why this system is called a chastotnik. It's simple - in the control unit there is a frequency converter, the functions of which are to provide soft start electric motor and maintaining the required water pressure.

The submersible household pump "Vodomet" of the Gileks brand has a number of undoubted advantages:

1. Creation of uninterrupted water supply.
2. Economy due to use storage tank and control unit.
3. Durability and reliability.
4. Low noise level unlike a conventional pumping station.
5. Protection of the main parts and details from overloads in the electrical network.

Submersible pumps of the "Chastotnik" system can operate at a well depth of up to 30 meters. The letter "Ch" has been added to the product labeling. For example, the designation of a similar design is the Water Cannon PROF 115/95 H, here the first numbers indicate the water flow in liters per minute, and the second part indicates the magnitude of the water pressure in meters.

The cost of these products ranges from 29 to 39 thousand rubles.

How to choose a Gilex pump

When choosing pumps for pumping water, a homeowner should consider the following factors:

1. Depth, diameter of the well.
2. The quality characteristics of drinking water, in particular, it is worth paying attention to the content of impurities of silt and sand. If they are more than normal, then any device of this type may fail prematurely.
3. The state of the electrical network, especially the frequency and magnitude of power surges.
4. And, of course, the price. However, choosing a cheaper model does not always mean its durability and reliability.

Some tips before buying a Gilex pump:

1. Many homeowners do not always delve into the depth of the issue - it seems to them that they bought the unit, installed it, and it should work properly for decades. However, the pump is a device that runs on electric current, the instability of its parameters may cause damage or deterioration of performance. Therefore, knowing domestic electrical networks, you should take care of purchasing a voltage stabilizer, which, among other things, will save all other appliances that consume electricity in the house.
2. You should not buy the most powerful pump, as this is not always economically feasible. In addition, if water is not collected in the well so quickly, that is, its low productivity, then this will not lead to anything good. Such a unit will quickly pump out the contents of the well, and then it will run idle - there is a possibility of its failure.
3. The composition of the water also affects the performance of the Gilex pump, like any other similar device. On the forums you can often see negative reviews about Gilex pumps, often all the comments boil down to the fact that it fails due to the high content of iron, lime and sand impurities. Even if you install an expensive imported pump famous brand, then it will also fail without taking into account and analyzing the water content in the well. And for some reason, some people are accustomed to speak negatively about domestic products. And often they are not worse than foreign goods.

Therefore, only taking into account all the norms and requirements for pumping equipment will help you choose the best product that will last for many years.

The pump "Vodomet" for a well is a multi-stage equipment with floating impellers washed by water. Water cooling is one of the important factors which prolongs the life of the device.

This pump "Dzhileks" for a well, the photo of which is presented in the article, has a fairly wide area of ​​​​use. It can be used in tanks, as well as open reservoirs. The equipment is perfectly adapted to difficult Russian conditions. To create it, the manufacturer uses durable and wear-resistant materials. For example, granite and ceramics are selected for. With regard to such important element, as impellers, a wear-resistant polymer is used for them.

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

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 this problem may be correct installation and installation of a check 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 has been 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.

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, they contain parameters that allow them to adapt the equipment 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 of 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 surface of the earth 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 of 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 the 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 cable is securely fixed at the top.
