Submersible sewage pump is a kind of used for transportation of solid particles and fiber hybrid liquid such as sewage and industrial waste water, mud and other environmental protection industry pump products. WQ type submersible sewage pump is composed of sewage pump, sealing system, submersible motor, control and protection system, automatic installation system, and so on. Different from the general sewage pump is: WQ type submersible sewage pump pump and motor coaxial rotating, and at the same time to dive into the work. The sealing system of the pump can effectively prevent the liquid from entering the motor chamber, and the safe operation of the motor is protected. Control and protection system to make the pump leakage, oil leakage, overload, overheating, lack of equal fault, the timely warning and downtime for repair.
Two, technical key
The automatic installation system is connected with the pipeline system or disconnected when the pump is installed and disassembled by the coupling device. WQ type submersible sewage pump is an indispensable important equipment in water treatment. It's safe operation directly affects the safe operation of water treatment system, therefore, in the WQ type submersible sewage pump, the main problem is to ensure the reliability of the pump, and the effects of sewage pump key problems using reliability and sealing performance of the pump and the non overload performance as well as the important parts of life, in the pump the seal, the vice impeller fluid power sealing new sealing technology combined with mechanical seal, the sealing reliability is improved greatly. While in the non overload performance, we use the theory of hydraulic design process for the pump, and adopts the double channel impeller, the pump not only has great ability through and it is more important in the whole range of lift pump power will not exceed the rated power of motor and motor overload.
