When using a variety of sewage pump without moorings so sewage pump must use the water level control principle to use. Otherwise, for example WQ sewage submersible pump in the water drained after cannot promptly stop the pump will cause sewage pump water cooling, and leads to the phenomenon that the submersible sewage pump motor burned, sewage pump failure can not automatically stop when will sewage pump fault phenomenon intensified.
The water level of the sewage pump control principle is mainly used to float ball liquid level sensor to the control cabinet and the control principle of the sewage pump is stopped, the floating ball is fixed inside the tank such as pool depth of 6 meters we preset the highest level of 5.5 meters, the lowest level of 1 meters to 5.5 meters, the water level float with the water level floating up when the floating ball is fed to the control cabinet signal to start the sewage pump, as the water level dropped to the lowest level of 1 meters will float along with the inverted signal after the float float will be inverted back to the control cabinet to the sewage pump sewage pump water level off, regardless of what way the sewage pump sewage pump control products all the control principle basically is such.
Sewage pump can be widely used in food, construction, paper making, sugar refining, metal (such as metal electrolysis), mining and water resources exploitation (such as cooling water, seawater desalination and desalination) and other industries. According to the requirements of different types of sewage pump can be divided into municipal sewage pump and industrial use of sewage pump. Municipal sewage pump is mainly used for the following transmission medium pumping sewage (e.g. residential area sewage, fecal sewage, wastewater sedimentation tank washing water), sludge (such as activated sludge, sludge, sludge digestion and sludge) and rain.
The digested sludge is the sludge which is obtained after the anaerobic digestion of the original sludge. However, the best choice of sludge similar to the sludge pump mud pump more appropriate.
