Guangdong pre-flow pump industry; what kind of axial flow submersible pump?
The axial flow submersible pump and the QHB type mixed flow submersible electric pump are updated products of the traditional water pump-motor unit. The motor driving the water pump is a dry fully enclosed submersible three-phase asynchronous motor. This type of submersible electric pump It can be immersed in water for a long time and has a series of incomparable advantages over traditional units.
1 Since the motor and water pump are integrated, there is no need to carry out the labor-consuming and time-consuming assembly process of motor-transmission mechanism-water pump axis alignment at the installation site, making on-site installation convenient and fast.
2 Due to submersible operation in water, the geotechnical and structural engineering of the pumping station can be greatly simplified, the installation area can be reduced, and the project cost can be saved by 30 to 40%.
3 The noise is low and there is no high temperature in the pumping station, which improves the operating environment. A fully underground pumping station can be built as required to maintain the environmental appearance of the ground.
4 The submersible motor adopts double or triple mechanical seals, grade F (temperature resistance 155 ℃), moisture-proof insulation, and protection grade IP68 (IEC). The pump section adopts a nationally designed hydraulic model, which has high reliability and is interchangeable with traditional water pump performance, making it easy for users to select.
6 It is easy to operate and easy to realize remote control and automatic control.
QZB and QHB submersible electric pumps can be used for farmland drainage and irrigation, and can also be used for industrial and mining docks, urban water supply and drainage, water supply projects, and power station water supply and drainage. Axial flow submersible electric pumps are suitable for low lift and large flow situations. Mixed flow submersible electric pumps have high efficiency and good cavitation performance. They are suitable for situations with large water level changes and high lift requirements. The transmission medium is raw water or light sewage. The maximum temperature of the transported liquid is 50 ℃.
