QJ (W) series horizontal submersible electric pump

The QJ (W) series horizontal submersible electric pump is a product that our company has redeveloped and designed based on years of research and production of submersible electric pumps. It is also an extension of our well submersible electric pump products. It is mainly used for extracting clean water from open water bodies (such as reservoirs, ponds, canals, etc.), and can also be used as a ground pump. The main unit of this series of electric pumps is composed of a QJ (W) submersible pump and its matching submersible motor, which work underwater as a whole. A specially designed device to help dissipate heat from the motor can force water flow along the motor casing, taking away the heat from the motor and reducing its temperature, ensuring the reliability of motor operation. This series of water pumps also has the advantages of compact structure, small volume, low noise, no secondary pollution, easy installation, use and maintenance, safe and reliable operation, high efficiency and energy saving, and no need to build a pump room.

Usage and characteristics:

The QJ (W) series horizontal submersible electric pump is a redesign developed by our company based on years of research and production of submersible electric pumpsA product that is also an extension of submersible electric pumps for wells. Mainly used for extracting clean water from open water bodies (such as reservoirs, ponds, etc.)Water channels, etc. can also be used as ground pumps. The main unit of this series of electric pumps consists of QJ (W) submersible pumps and their matching submersible motorsDiving underwater as a whole for work. Specially designed a device to help dissipate heat from the motor, which can force water flow along the motor casingMoving, taking away the heat of the motor, thus reducing the temperature of the motor and ensuring the reliability of motor operation. This series of water pumps also hasCompact structure, small size, low noise, no secondary pollution, easy installation, use and maintenance, safe and reliable operation, high efficiency and energy savingAdvantages such as no need to build pump rooms.

Compared with other ground water supply and drainage pumps, the QJ (W) series horizontal submersible electric pump has the advantages of occupying less space, no pollution and leakage, and safetyAdvantages such as easy installation and use. Can be used for water supply in residential areas, high-rise buildings, villas, and other places.

Usage conditions

1. Power supply: three-phase AC, voltage 380V, 660V, 1140V, frequency: 50Hz

2. Water source:

(1) Water temperature: QJ (W) type ≤ 20 ℃

(2) The total content of solid impurities in water (weight ratio) shall not exceed 0.01%

(3) The chloride ion content shall not exceed 400mg/L

(4) PH value 6.5~8.5

The above conditions are basic usage conditions. If the usage conditions exceed the above range, special measures can be made to ensure the normal operation of the pump

Horizontal submersible electric pump

Structural characteristics

The water pump part of the QJ (W) horizontal submersible electric pump is composed of multi-stage centrifugal impellers connected in series in sections, and the impeller of the high head water pump is openBalance holes can effectively reduce axial forces. The pump stages are connected by bolts, and each section is supported by special bearings to ensure water supplyReliability of pump operation. The top of the high lift pump is equipped with a check valve body, which can prevent liquid reflux in the pipeline from damaging the electric pump after shutdown.The water outlet part of the motor cooling device has the effect of a short pipe, so there is no need to equip a separate short pipe, and it is also used to connect and fix the electric pump.The supporting submersible motor is a closed water filled three-phase asynchronous motor, with windings made of water-resistant polyethylene insulation and a multi-layer structure of nylon sheathThe electromagnetic wire. The guide bearing and thrust bearing are both water lubricated bearings, and the upper part of the motor is equipped with a sand control device to prevent sediment from entering the motorInternal cavity of the machine.

Scope of complete supply

1. One set of host

2. Pipelines: water pipes, bends, gaskets, etc

3. Cable: Cable and cable joint materials

4. Control cabinet: start-up and protection devices
