2xz Series rotary vane vacuum pump is double stage high speed oil sealed rotary vane vacuum pump.Its pumping principle is as same as that of 2X type pump .Rotors are eccentrically mounted within the cylindrical housing of the stators and vanes are fitted freely inside the respective slots of the rotor.
2xz Series 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 .
2xz Series 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.
Field of Application :
1) The pump is one of the basic equipments to exhaust a sealed vessel.
2) The pump is allowed to work continuously for many hours at a stretch under atmospheric temperature of 5 degree-40 degree 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.
