Introduction

An overview,
The company developed the WQ series of suction sewage submersible pump, suitable for all kinds of harsh environments of sewage and sludge pumping discharge deposition. Water pump for the suction, can dry face of surface water. Motor for diving three-phase asynchronous motor. Cover an area of an area small, easy installation and use, reliable and durable, long service life.
Second, using the environment and working conditions
1, the power frequency 50 hz, the use of the rated voltage of 380 v or 660 v (tolerance: + / - 5%) of the three-phase ac power supply.
2, transmission medium solid volume ratio below 2%, the medium density maximum 1.2 x 103 kg/m after.
3, transport medium since the pH value of 4 ~ 10.
4, medium temperature does not exceed 40 ℃.
Three, structure features
1, WQ series under suction sewage submersible pump by diving three-phase asynchronous motor and sewage pump is composed of two parts. A pump body straight, at the bottom of the motor and its intermediate a reliable mechanical seal device, can effectively prevent the cooling fluid in the motor and the exchange between pumping medium, ensure water pump long-term reliable operation.
2 for polyethylene water resistant nylon sheathed for motor winding, electromagnetic wire, the motor can be divided into two type oil charge and water filling. Oil filling machine lumen and 10 sealed cavity perfusion machine oil or 25 # transformer oil (for pumps, vertical submerged on bearing is limited, can not fill), motor adopts the centripetal ball bearings; Cavity filled with clean water in the water filling machine (must fill), upper with water lubricated sliding bearing, the lower the centripetal ball bearings, ball bearings to the heart of indoor filling high temperature molybdenum disulfide grease, easy tear open outfit, easy maintenance.
3, small flow water pump for centrifugal or turbulent flow structure, used for pumping ordinary sewage engineering high-lift lose drainage; Large flow for shuangliu non-clog pump or mixed flow structure, is used in the coal washery sewage circulation, slurry pumping and agricultural river water, etc.
4, electric pump design full consideration without blocking a key problem, make the impurity particles through good performance.
5 installed cooling jackets, motor shell, motor can work in a certain time above the water, electric pump structure, adopting the built-in structure was sent liquid discharge by motor, motor parts can work long time above the water.
Excessively high 6, in order to prevent the motor chamber pressure casing crack, in the upper cover is equipped with a pressure relief valve.
