Vacuum pump is a kind of positive displacement pump. The size of the pump body determines the concave convex power of vacuum pump. At present, the round pump body is widely used in vacuum pump at home and abroad. The advantage of such planning lies in the convenience of processing and installation; therefore, the power of vacuum pump is not high. The main reason is that the impeller of vacuum pump needs more centrifugal force to make the sealing liquid separate the inlet and exhaust of vacuum pump.
The sealing liquid in the vacuum pump can transfer energy and seal effect in the vacuum pump, but the vacuum pump can only reach the planned volume as far as possible because of the structural constraints in the suction and discharge cavity, while the traditional vacuum pump body is the welding pump body, with smooth steel plate surface, and the straight impact of the sealing liquid on the smooth surface will show a straight-line repeated turn back, and then secondary noise will occur, which is smooth The surface of the vacuum pump has no ability to absorb noise.
Low noise vacuum pump features: compact structure, small floor area. Because the gas is compressed in the pump, the power consumption is low. Because there is no oil in the vacuum chamber, the dust will not stay in the pump chamber, but will be discharged out of the pump with the gas from the exhaust port. Moreover, it can deal with the problems of oil emulsification, frequent replacement of working fluid, frequent protection and maintenance, and save the use cost.
