Submersible Sewage Pump

WQ series submersible sewage pump is composed of water pump. seal and motor. The motor is located in the upper part and is divided into single-phase and three-phase asynchronous motors. Used between pump and motor double-end mechanical seal, each fixed end seal is sealed with O-type oil-resistant rubber sealing ring for static sealing The mechanical seal of key parts adopts cemented carbide and high-quality silicon carbide as material, the shaft is made of 45 # steel or stainless steel.to ensure the shaft has reliable mechanical strength and certain wear resistance and corrosion resistance.

The stator of the high-power sewage pump is embedded with a thermal control switch. Normal temperature is"normally closed" state, when the stator temperature reaches 125°C, the switch opens. A water leakage probe is installed in the oil chamber for water leakage detection. The signal line of the oil and waterintake probe is connected. Connect any line to the leakage circuit breaker; when the mechanical seal on the pump side leaks and the oil-water ratio in the oil chamber reachesa certain concentration, the oil-water probe will send an alarm signal and the power supply is cut off and the pump stops working automatically.
