Description:

QW type submersible nonclog sewage pump is made up of motor and pump, they are separated through oil isolation room and mechanical seal, it is short in length that motor and pump share the same axle (rotor), the structure is compact. Equipped with many kinds of protectors, it is running reliably, the function of its main parts are as follows:
　1. signal line: equipped with control box, protecting the pump fully, including leakage, phase reversal, short circuit, overheated, overload, etc
2. motor stator: its insulation is B grade or F grade.
3.water leakage probe. This component is installed in the oil room, if the mechanical seal was damaged, and water enters into the oil room, it will send out the signal to the control system so as to protect the pump.
4.Mechanical seal: Adopting in-series seal, the material is the wear-resisting carbonization tungsten, featuring being reliable, wear resisting, longer life, etc.
5.Impeller: have better handling capacity, can reduce the trouble of jamming and twisting of big fiber rubbish, etc.
6.Pump body: harmonize with impeller, ensure the pump has high efficiency.
7. seal rings: Installed at the mouth place of pump body, make mouth surround as impeller office wear and tear, can change the sealed ring because of operating, so as to ensure the pump runs with the best efficiency.
