The use range of sewage pump: (1) enterprise unit wastewater discharge. (2) the discharge system of urban sewage treatment plant. (3) subway, basement, civil air defense system drainage station. (4) discharge of sewage from hospitals, hotels and high-rise buildings. The sewage drainage station in the residential area. The municipal engineering construction site in the mud, dilute emissions. Water supply device, tap water factory. The farms and rural sewage irrigation. To exploration and mining equipment for water treatment. The place of the shoulder arm, pumping mud.
The characteristic of the sewage pump is to adopt the unique single leaf or double blade impeller structure, which greatly improves the ability of passing through the dirt. It can effectively pass 5 times of the fiber diameter of the pump caliber and the solid particles with a diameter of about 50% of the pump diameter. (2) mechanical seals adopt new hard and corrosion-resistant tungsten carbide materials. At the same time, seal is improved to double face seal, so that it can run in oil chamber for a long time, enabling pump to run safely and continuously for more than 8000 hours. 3. The overall structure is compact, small volume, small noise, significant energy saving effect, convenient maintenance, no need to build a pump house, and can work in the water, which greatly reduces the project cost. The high precision anti disturbance water leakage detection sensor is set up in the seal oil chamber of the pump, and the heat sensitive element is buried in the stator winding, and the pump motor is absolutely protected. 5. According to the needs of users, the automatic safety protection control cabinet is equipped to protect the leakage, leakage, overload and over temperature of the pump, so as to improve the safety and reliability of the product. The float switch solution based on the required changes, automatic control of pump start and stop, without special care, it is very convenient to use. And according to user needs with double rail automatic coupling installation system, which brings great convenience to installation and maintenance, this may not enter the sewage pit. It can be used in the whole range of lift, while the motor is not overloaded. We have two different installation methods, fixed automatic coupling installation system, mobile free installation system.
The structure and performance of self-priming sewage pump sewage pump, learn the advantages of similar products at home and abroad, suggestions are provided and and absorption use requirements of the majority of users, to develop into a set of self suction and discharge in a can, like water self-priming pump that does not need safety valve, not need water, and aspirate containing big solid block, long fibers of dirt, sediment, mine waste contamination, waste treatment and sewage works all and colloidal liquid;
The sewage pump can be divided into self suction pump, underwater discharge pump, knife type sewage pump and automatic sewage pump according to the difference of discharge mode. Because it can transport with hard solids, fibers, liquid, and particularly dirty, sticky and slippery liquid, is widely used in mining, papermaking, printing and dyeing, environmental protection, oil refining, petroleum, chemical industry, farm, dyeing, wine, food, chemical fertilizer, coking plant, building, marble factory, mud, sand, mud, sewage pond, dirty liquid suction feeding sewage treatment thick liquid, filling and suspended matter in.
The selection and maintenance of sewage pump for sewage pump is the most critical issue is the reliability problem, because of the need of transmission medium of solid materials are mixed with liquid, the problem of the sewage pump in a sealed, motor bearing capacity, bearing arrangement and the use of requirements to be higher than the average pump, so in the selection, we must clearly understand the sewage pump sealing reliability and load capacity.
