A high-precision anti-interference water leakage detecting sensor is arranged in the sealing oil chamber of the sewage pump, and a thermal element is embedded in the stator winding to absolutely protect the water pump motor. The automatic safety protection control cabinet can be equipped according to the user's needs, and the pump's water leakage, leakage, overload and over-temperature are absolutely protected to improve the safety and reliability of the product. The float switch can automatically control the start and stop of the pump according to the required liquid change, without special care, and is extremely convenient to use. The double-rail automatic coupling installation system can be equipped according to the user's needs, which brings great convenience to installation and maintenance, and people do not have to enter the sump for this purpose. It can be used in the full lift range to ensure that the motor will not be overloaded. The sewage pump has two different installation methods, a fixed automatic coupling installation system and a mobile free installation system. The structure and performance of the self-priming sewage pump in the sewage pump draw on the advantages of similar products at home and abroad, and absorb the use requirements of the users and the improvement suggestions provided by many aspects, and the self-priming and sewage discharge are developed. It can be used like a normal water self-priming pump without a safety valve. It does not need to be filled with water. It can also suck dirt, sediment, waste minerals, manure treatment and all engineering sewage and glue containing large solid blocks and long fibers. Liquid.
The automatic mounting system automatically couples or disconnects the piping system during installation and removal through the coupling device. The WQ submersible sewage pump is an indispensable and important equipment in water treatment. Its safe operation directly affects the safe operation of the entire water treatment system. Therefore, in the WQ submersible sewage pump, the most important problem is to ensure the reliability of the pump, and the key problem affecting the reliability of the sewage pump is the pump. The sealing performance and no overload performance and the service life of important components, in the pump seal, the new sealing technology combined with the sub-impeller fluid dynamic seal and mechanical seal, the sealing reliability has been greatly improved.
