Product Features
WQ/B flameproof submersilble sewage pump is the company's latest development of submersilble pumps according to marketdemand, is the latest product with inaependent intelectual propery ighis, The pump is mature in siucture, relable in opercfion anaexcellent in perfomance. lt is mainly used in petroleum and petrochemical customers;Products, GB3836.1-2010, explosive environment, ist part: General reguirements for eauiomentGB3836.2-2010 explosive environment-Parsecond: equipment protected by fameproof enclosure "a".Explosion proof sians are: Exd ll BT4 (can be desianed according to requirements Exd l Ct4);The whole stip casing head submersilble cable seal design; cable end processing special, even if the cable sheath damaged doesnot have the water soaked into the motor, ol resistant rubber sot cable with naional standard GB/ 5013.4 and JB/T 8735.2: But the end oicable can not conltact wih water, waier inio the calle wi seiousy reduce the insullion resstance of the cable, allecing he safely of the motorHigh perfomance of squlrel cage induction motor, especialy for submersille pump design manufacture, confoms to the GB755standord. the motor insulction class is f, protecfion arade of the motor shel is lPX8, power is less than or eaual to 75kW ivoe pump, motostator wih 145 DEG C thermal protector, the maximum working temperature is 145 degrees cenigrade, ensure that the water pumprunning motor is not running to prevent overheating, buming equipment;Blade or runner type large channel impeller, with strong ani winding and no clogging perfomance, good perfomance, matureand stable, through dynamic and static balance test, stable operation;Pump head and motor coaxal, using shor axs exienson siucture design, compact stucture, rom desan and manutactuing to reducethe deflection of the shaft, vilbration when running smal, so that the sealing and bearing life longer;[wo sinale face mechanical seal independent seal, the motor and the pump completely sealed isolcfion, mounted in seres, providesdouble insurance, to further improve the reliablity of the seal, the pump to ensure long-tem reiable operation;Pump body is a single volute, distibuted around the impeler to colect lquid, the fow surface smooth and smooth, cross section of thechannel, high effciency, no plug;iyoe pumo power is larger than lkw, the chamber cover in the upper part of the stator chamber and the oll chamber cavily areprovided with leak signal sensor, capable of monitoing the operation state of the pump continuously and eftectively, can realize theprotection of the pump control cabinet, to eliminate the fault, ensure the pump operation;,Bearings use roling beaings, which can bear axial and radial loads, and are completely separoted fom the medium convevec
by the pump;1 ikw pump type cooling water jacket can be configured according to user needs, through the special structure design of the circulatingcoolina woter in the iacket, ake the motor heat, even in the diry oump instolation envronment or the woter level is ow under thecondition of nomal operation.
