Axial-flow submersible pumps, QZB-type axial-flow submersible pumps and QHB-type mixed-flow submersible pumps are the replacement products of the traditional water pump-motor unit. The motor driving the water pump is a dry-type fully enclosed submersible three-phase asynchronous motor. This type of submersible motor The pump can be immersed in water for long-term operation, and has a series of unparalleled advantages of traditional units.
Because the motor and the water pump are integrated, there is no need to carry out the labor-consuming and time-consuming assembly process of the axis of the motor-transmission mechanism-water pump at the installation site, and the on-site installation is convenient and fast.
Due to submerged operation, the geotechnical and building structure engineering of the pumping station can be greatly simplified, the installation area can be reduced, and the project cost can be reduced by 30-40%.
The noise is low and there is no high temperature in the pumping station, which improves the operating environment. An all-underground pumping station can be built as required to maintain the environment on the ground.
The submersible motor adopts double or triple mechanical seals, class F (temperature resistance 155 ℃) moisture-proof insulation, and protection class IP68 (IEC). The pump section adopts a nationally designed hydraulic model with high reliability and interchangeability with traditional water pump performance, which is convenient for users to select.
Convenient operation, easy to realize remote control and automatic control.
The use of this type of submersible electric pump is the most thorough way to solve the problem of building pumping stations along the river and lakes where the water level fluctuates greatly, and to solve the problem of motor flood control, and it eliminates the long shaft and intermediate bearings between the pump and the pump, making the unit run more stable reliable.
QZB and QHB submersible electric pumps can be used for irrigation and drainage of farmland, as well as for industrial and mining docks, urban water supply and drainage, water supply engineering, and power station water supply and drainage. Axial-flow submersible pumps are suitable for low-lift and large-flow occasions. Mixed-flow submersible pumps have high efficiency and good cavitation performance. They are suitable for occasions with large water level fluctuations and high head requirements. The conveying medium is raw water or mild sewage. The highest temperature of the liquid being transported is 50 ℃.
