QW submersible sewage pump product introduction
QW submersible sewage pump is mainly used in municipal engineering, industrial, hospitals, construction, hotels, restaurants and other industries. For discharging sewage sludge, waste water,city with solid and long fiber (including occasions corrosive,aggressive media), has the advantages of high efficiency, anti winding, no blocking, automatic coupling, high reliability andautomatic control, in the carriage of solid particles and long fiberwaste, has a unique function. Can according to user requirements for automatic water level control, and automatic protection device and control cabinet, automatic installation of dual rail system etc..
QW submersible sewage pump use application
1, The motor rated voltage 380V, frequency 50HZ AC power supply.
2, The transmission medium temperature not exceeding 40 °.
3, The delivery of liquid medium pH value 4-10.
4, Conveying the solid medium volume ratio below 2%.
5, The transmission medium density is less than 1.2 × 103Kg/m3
QW submersible sewage pump performance characteristics
QW submersible sewage pump structure is compact, and set the various status display, protection device, safe, reliable operation ofthe pump.
1, The cable sealing design, eliminates the hidden trouble of water leakage cable.
2, Stator insulation class F, with thermal protection element.
3, 18.5KW above pump adopts automatic cooling circulating waterpump, ensure the operation safety at the lowest water level.
4, The motor cavity is arranged at the bottom of the float switch, the motor side mechanical sealing monitoring.
5, At the upper end of the pump and motor oil chamber is provided with an oil-water probe of mechanical seal, pump sideimplementation monitoring, once the water leakage, the control system will alarm protection.
6, Bellow type mechanical seal, and sealing materials for tungsten carbide, silicon carbide and tungsten carbide, prevents water from entering the motor, to ensure safe and reliable operation of the motor.
7, Balanced mechanical seal external pressure for vice impeller,prevent water from entering into the oil chamber, thereby prolongingthe service life of the electric pump.
