Interpretation of working principle of sewage submersible pump

With the price of housing in our country has been high, housing is now more and more intensive, in the usual sewage treatment, manure pumping and hotel sewage treatment and so on need to be timely and effective, these sewage treatment can not be separated Sewage treatment vehicles, however, because of site constraints, sometimes need to install their own equipment, such as pumps can be mounted on tricycles, tractors, gas cars, with the use of the motor. But if you do not understand the use of sewage submersible pumps, it is estimated to encounter a lot of trouble. Sewage submersible pump works explain Next, the main submersible pump sewage works: 1, the main pump is the so-called main pump of the vacuum pump is directly drawn to the vacuum vessel, in order to obtain the vacuum required to meet the process requirements of the vacuum pump, ultra-high Vacuum pump Ultra-high vacuum pump is the vacuum pump working in the ultra-high vacuum range. 2, roughing pump roughing pump refers to the atmospheric pressure began to reduce the pressure of the vacuum system to another suction system can start working vacuum pump, rough vacuum pump or low vacuum pump rough, low vacuum pump is from the atmosphere to reduce the pressure is to be pumped container After working in the low vacuum or rough vacuum pressure range of the vacuum pump. 3, the fore-pump The fore-stage pump is used to maintain the pressure of the previous stage of the other pump to its maximum allowable pressure below the previous level of the vacuum pump, high vacuum pump High vacuum pump is to work in a high vacuum range vacuum pump. 4, maintain the pump to maintain the pump means that when the vacuum system is very small, can not effectively use the main pump. To this end, in the vacuum system is also equipped with a lower suction speed auxiliary foreline pump to maintain the normal operation of the main pump or vacuum pump to maintain the vacuum required for the evacuated container. Suction sewage truck vacuum pump is a rough vacuum pump, it can get the ultimate vacuum of 2000 - 4000Pa, series atmosphere jet up to 270 - 670Pa. Water ring pump can also be used as a compressor, called the water ring compressor, is a low pressure compressor, the pressure range of 1 - 2 × 105Pa gauge pressure. The use of equipment, the level of efficiency, the need for its working principles and methods of use to do more detailed research, with the increase in the use of such products in our country, to do more research on it not only can improve the vitality of products, but also can improve The competitiveness of products.
