The basic principle of submersible sewage pump

First, the basic principles
Submersible sewage pump is a kind of pump used in the environmental protection industry to transport solid-liquid mixed liquid such as solid particles, fiber, such as domestic sewage, industrial wastewater, mud and so on. WQ submersible sewage pump consists of sewage pump, sealing system, submersible motor, control and protection system, automatic installation system and other parts. And the general sewage pump is different: WQ-type submersible sewage pump and motor coaxial rotation, and dive into the liquid at the same time work. The pump sealing system can effectively prevent the liquid into the motor cavity, the protection of motor safe operation. Control and protection system to pump in the event of leakage, oil spills, overload, overheating, lack of equal fault, timely alarm and shutdown for repair.
Second, the technical key

The automatic mounting system allows the pump to be automatically connected or disconnected from the piping system during installation and removal by a coupling device. WQ submersible sewage pump is an indispensable important equipment in water treatment. Its safe operation directly affects the entire water treatment system safe operation, therefore, in the WQ type submersible sewage pump, the most important question is guarantees the water pump use reliability, but affects the sewage pump use reliability the key question is the pump Sealing performance and no overload performance and important parts of the service life of the seal in the pump, we use the auxiliary impeller hydrodynamic seal and mechanical seal combination of new sealing technology, the sealing reliability has been greatly improved. In the absence of overload performance, we use the whole field theory of pump hydraulic design, while using dual-channel impeller, the pump not only has a greater capacity and more importantly, the pump in the entire range of power will not exceed Motor rated power using motor overload.
