Large Flow Electric/Diesel Fire Fighting Water Pump
WQ(QW)non-cloggingsubmergedsewage pumpiscomposed of motor and pump that are isolated by oil isolationchamber and mechanical seal components.it is a product ofmechanical and electricalintegration,with motor and pumpsharing a common shaft (rotor) to feature overall short dimensionsand compact structure of pump. And it is equipped with manyprotective devices to keep pump running safely and reliably. Thefunctions of its main components are set forth below:
Signal line 1:equipped with full automatic pump controlcabinet to carry out complete protection on pump, including waterleakage, phase failure, short circuit, overheating, motor overloadand etc.
Motor stator 8: insulation of level B or F.
Water leakage probe 11: fitted inside the oil chamber. Oncemechanical sealis damaged and water comes into the oichamber, the probe will send out signal and the control system willcarry out protection on the pump.
Mechanical seal 13:use of double channel seal in series.made of hard tungsten carbide to feature reliable sealing, wearresistance, long service life and so on.
Impeller 17:single or double channel structure to offeroutstanding throughput capacity to handle sewage containingarge material and fibre, and to decrease the failure of cloggingand winding.
Pump body 15: matched with impeller to offer high efficiency.Sealing ring 18: fitted at the ring of pump body. When there isabrasion at the body ring caused by the running of impeller, havethe sealing ring replaced to maintain pump running at the bestefficiency.
