reciprocating vacuum pump
Molecular formula :

nature : reciprocating piston pump gas for a vacuum pump. Its basic structure and principles with the same reciprocating compressors. But the vacuum pump high compression ratio, the gas pressure suction small, so I pump the volume gap must be smaller, and from inhalation valve to be more flexible and lightweight. I gap to reduce the negative impact of piston cylinder connected with the balance at both ends around the airway. Intake and exhaust valve use of slide-valve structure, instead of valve springs. Generally dry operations. If gas, which contains large amounts of steam, we must get rid of condensation steam after re-entering the pump for high vacuum.
