The QX type engineering submersible electric pump consists of three parts: water pump, seal, and electric motor. The electric motor is located at the upper part of the electric pump and is a three-phase asynchronous motor; The water pump is located at the lower part of the electric pump and has a centrifugal impeller and volute structure; Hard alloy mechanical seals are used between the pump and the motor, and "O" - shaped oil resistant rubber seals are used for static sealing at each fixed stop.  
·The shaft of the electric pump is treated with hard chrome plating, which can effectively improve the wear resistance and corrosion resistance of the shaft, and also facilitate the maintenance and disassembly of the impeller.
·The electric pump is equipped with a thermal protector, which can automatically disconnect the power supply to protect the motor in case of phase loss, overload, motor overheating, etc.
This series of submersible electric pumps is widely used in construction sites, mines, farmland, and other places. It is an ideal equipment for pumping liquids containing trace amounts of small particles, such as mine water, domestic wastewater, and river pond water. Shanghai Yugong Pump Industry, a water pump manufacturer in Shanghai, welcomes new and old users to purchase.  

2、 Submersible pump usage conditions:
Submersible electric pumps can operate continuously and normally under the following usage conditions:
1. The medium temperature shall not exceed+40 ℃;  
2. The pH value of the medium is between 6.5-8.5;  
3. The volume ratio of solid impurities in the medium shall not exceed 0.5%, and the particle size shall not exceed 3mm
4. The power supply has a three-phase voltage of 380V, a frequency of 50Hz, and a voltage fluctuation range of 0.9-1.1 times the rated value.
5. Diving depth not exceeding 5m
