The limit vacuum of reciprocating vacuum pump system (also known as piston vacuum pump) is 4x102pa-103pa for single stage, 1pA for double stage and 45m3 / h-20000m3 / h for pumping from sealed container. The content of extracted gas is not more than 35t. If auxiliary equipment, such as refrigerator, is added, swallowing gas can also be extracted. The reciprocating vacuum pump system has a large exhaust volume, which is mainly used for vacuum impregnation, steel vacuum treatment, vacuum distillation, vacuum concentration, vacuum crystallization, vacuum dry bath, vacuum filtration and concrete vacuum operation.
Reciprocating vacuum pump system is not suitable for conveying corrosive gas or gas containing particle dust. If there is dust in the suction valve, a filter must be installed at the inlet of the pump. The oil-free reciprocating vacuum pump adopts the piston ring and sealing ring made of self-lubricating materials, so it is unnecessary to add lubricating oil in the cylinder; an oil separator is added between the cylinder and the engine body (the length is greater than one stroke length), so as to prevent the lubricating oil in the engine body from leaking into the cylinder along the piston rod, thus no pollution is caused to the pump system. Oil free reciprocating vacuum pump has vertical and horizontal structures.
The application scope of reciprocating vacuum pump system is as follows: ① in the environment requiring vacuum cleaning; ② when the air bird needs to be recovered, the recovered gas can be filled in the air chamber to ensure the purity of the gas; ③ when the flammable and explosive gas is removed, the inert gas can be filled in the air chamber. Isolate the chamber to prevent air (suspicious auxiliary equipment) from leaking into the cylinder and avoid accidents.
