Rotary Vane Vacuum Pump Application
1. The pump is one of the basic equipment to exhaust a sealed vessel. It can be used either independently as main and can also be served as for pump for booster pump diffusion pump and molecular pump or as holding pump for a vacuum system and as a pre-pumping for different kinds of the pumps. So that is can be applied in electro-vacuum industries, vacuum flask manufacturing, vacuum welding and as an accessory to those fine gauges or meters where vacuum is required .It is more suitable for laboratory use because of its small size ,less weight and quiet operation.
2.The pump is allowed to work continuously for many hours at a stretch under atmospheric temperature of 5℃-40℃ and intake pressure below 1230pa.While the pumped gas containing moisture of a relative humidity of more than 90% gas-ballast valve should be open.
3. Whit the inlet port widely opened to atmosphere the pump is not allowed to work more than one minute.
4.The pump is not suitable for pumping over-oxidized, poison, explosive and corrosive gas as well as gases which react chemically with the pump oil contain particles of dust.
Rotary Vane Vacuum Pump Description
2XZ-4 type pump is equipped with gas-ballast valve. Its function is to fill the exhaust space with certain amount of air ,when the valve is open ,so to reduce the proportion of the partial pressure of vapor in the total discharge pressure .As the partial pressure of vapor is lower than that of the saturated vapor pressure corresponding to the working temperature of the pump, vapor can be discharged from the pump with the filled air in order to avoid condensation of vapor in the pump oil and to prevent oil from emulsifying by the condensed vapor so as to prolong the useful lift of oil .However the ultimate vacuum of the pump shall drop ,and the temperature of the pump shall rise when the gas-ballast valve is open .
2XZ-4 type pump has the outstanding achievements of small size, less weigh ,quiet operation and easy to start .Besides devices to prevent from sucking back of oil and leakage of oil from axle sealing to contaminate environment are also provided.
