QJ(D) type small multi-stage submersible pump for wells is a new generation of products specially developed by the company. It implements GB/T2816-2002 national standard. Its compact structure, excellent performance, easy to use, safe and reliable, is a practical generation. product. The electric pump water consists of three parts: the water pump seal and the electric motor. The pump is located in the upper part of the multi-stage centrifugal impeller. The motor is located in the lower part of the single-phase or three-phase asynchronous motor structure. The pump and the motor are mechanically sealed as seals. The “O” seal is sealed at the mouth seal. Due to the multi-stage impeller structure, the electric pump has high lift and wide application, and can be used in residential water supply, industrial water circulation, agricultural irrigation, construction and construction water and other places. The temperature of the electric pump conveying medium does not exceed 35 degrees Celsius, the PH value is between 6.5-8.5; the power supply is 50 Hz, the single-phase voltage is 220V, the three-phase is 380V, the diving depth is no more than 150m, and the minimum diving depth is not less than 1m.
