The sewage pump adopts a unique single blade or double blade impeller structure, greatly improving the sewage passing capacity, and can effectively pass through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter. The mechanical seal adopts a new type of hard and corrosion resistant tungsten carbide material, and the seal is improved to a double end seal, which allows the pump to operate safely and continuously for more than 8000 hours in the oil chamber for a long time. The overall structure is compact, small in size, low in noise, significant in energy saving, and convenient in maintenance. It does not require the construction of a pump house. It can work by diving into the water, greatly reducing project costs.

The sealing oil chamber of the sewage pump is equipped with a high-precision anti-interference water leakage detection sensor, and a thermal sensitive element is embedded in the stator winding to provide absolute protection for the water pump motor. According to user needs, it can be equipped with a fully automatic safety protection control cabinet to provide absolute protection against water leakage, leakage, overload, and overheating of the pump, improving the safety and reliability of the product. The float switch can automatically control the start and stop of the pump according to the changes in the required liquid, without the need for special personnel to take care of it, making it extremely convenient to use Double guide rail automatic coupling installation system can be equipped according to user needs, which brings great convenience to installation and maintenance, and people do not need to enter the sump for this purpose. ⑧ It can be used within the full lift range, ensuring that the motor does not overload. There are two different installation methods for sewage pumps: fixed automatic coupling installation system and mobile free installation system. The structure and performance of the self priming sewage pump in the sewage pump, drawing on the advantages of similar products at home and abroad, and absorbing the use requirements and improvement suggestions provided by the vast number of users in various ways, is developed to integrate self priming and sewage drainage, which can be similar to ordinary clean water self priming pumps without the need for a bottom valve and irrigation, and can also suck dirt, sediment, waste mineral impurities containing large solid blocks and long fibers Treatment of feces and all engineering sewage and colloidal liquids.

The automatic installation system uses a coupling device to automatically connect or disconnect the pump from the piping system during installation and disassembly. 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 main issue of Z is to ensure the reliability of the pump, while the key issues affecting the reliability of the sewage pump are the sealing performance and non overload performance of the pump, as well as the service life of important components. In the sealing of the pump, a new sealing technology combining hydrodynamic sealing and mechanical sealing of the auxiliary impeller is adopted, The sealing reliability has been greatly improved.
