Product overview:
QW submersible sewage pump, QW submersible sewage pump adopts large flow channel anti-blocking hydraulic components design, greatly improve the sewage through ability, can effectively pass through the pump diameter of 5 times fiber material and the diameter of the pump diameter of about 50% of the solid particles.Reasonable design, reasonable supporting motor, high efficiency, remarkable energy saving effect.Mechanical seal adopts double series seal, made of hard wear-resistant tungsten carbide, which is durable and wear-resistant, and can make the pump run safely and continuously for more than 800 hours.Pump compact structure, small volume, easy to move, easy to install, no need to build pump room, diving into the water can work, greatly reduce the project cost.There is an oil-water probe in the pump oil room. When the mechanical seal on the pump side is damaged, the water enters the oil room and the probe signals to protect the pump.
Automatic safety protection control cabinet can be equipped according to the needs of users to monitor the leakage, electricity leakage, overload and overtemperature of the pump to ensure reliable and safe operation of the pump.Double guide rail automatic coupling installation system, to the installation of pump installation, maintenance has brought great convenience, people do not have to enter and exit the sump.The float switch can change according to the required water level.Automatic control of the pump stop, without special care.Ensure that the motor does not run under load within the range of using head.The motor can adopt the water jacket type external and third party circulation cooling system according to the use situation, which can ensure the safe operation of the electric pump under the condition of no water (dry).Installation mode has fixed automatic coupling installation and mobile free installation two kinds, can meet different occasions.QW type non-clog diving sewage pump consists of two parts: motor and pump, which are separated by oil isolation chamber and mechanical sealing components. It is an electromechanical integration product. Motor and pump share the same shaft (rotor).
Signal line 1: equipped with fully protected water pump control cabinet to protect the pump in all aspects, including leakage, phase break, short circuit, overheating, motor overload, etc. Motor stator 8: B or F insulation.Leakage probe 11: the element is installed in the oil room. When the mechanical seal is damaged, water enters the oil room, and the probe can send a signal to protect the pump by the control system.Mechanical seal 13: adopt double series seal, choose new hard corrosion resistant tungsten carbide material, with reliable seal, wear resistance, long life and other characteristics.Impeller 17: the impeller adopts single channel or double channel structure, with a strong ability to pass through large materials and fiber waste, reduce the blockage, winding fault.Pump body 15: with impeller, so that the pump has a high efficiency.Seal ring 18: installed in the pump body at the mouth ring, when the impeller due to the operation of the mouth ring wear, can be replaced by the seal ring, to ensure the pump to operate with the best efficiency.
