What is the reciprocating vacuum pump?

Also known as the piston vacuum pump, by reciprocating the piston pump chamber (cylinder) of the working capacity of the cyclical changes in the vacuum pump. Reciprocating vacuum pump structure and reciprocating piston compressor similar. Work, the suction pipe is connected to the vacuum container, the exhaust pipe through the atmosphere. Reciprocating vacuum pump pumping large, pumping rate range of 45 ~ 20000 cubic meters per hour, single-stage pump ultimate pressure of about 10 (Pa, two-stage pump up to 1 Pa. Reciprocating vacuum pump can be used for vacuum distillation, vacuum concentration, vacuum Crystallization, vacuum filtration, vacuum drying and concrete vacuum work, etc. If the condenser is installed at the suction inlet of the pump, the gas containing water vapor can be removed; if the filter is installed, the gas containing dust can be removed.
