Mini Lab Mechanical Sealed Rotary Vane Oil Pump
Advantages of rotary vane vacuum pump:
√ Compact size, light weight, low noise.√ The automatic return oil check, oil does not return.√ No pollution, energy-saving, nice appearance.√ Competitive price and easy to operate.
Applications of rotary vane vacuum pump:
Widely used in electronic, refrigeration, light source, chemical industry, medical treatment, glass king,evaporation and dry industries and so on. Can be installed with booster pump, diffusion pump and molecular pump as the first stage pump, easily start as it equipped a valve on the axis to prevent oil returning to the pump chamber when stopping the pump, prolong the life of pump oil with the installation of a gas ballast valve to avoid vapor condensates and mixes into pump oil. Oil mist trap equipment also installed to protect the environment.
Operating principle of rotary vane vacuum pump:
A rotary vane vacuum pump is an oil-sealed rotary displacement pump. The pumping system consists of a housing, an eccentrically installed rotor, vanes that move radially under centrifugal and resilient forces and the inlet and outlet. The inlet valve, if available, is designed as a vacuum safety valve that is always open during operation. The working chamber is located inside the housing and is restricted by the stator, rotor and the vanes. The eccentrically installed rotor and vanes divide the working chamber into two separate compartments with variable volumes. As the rotor turns, gas flows into the enlarging suction chamber until it is sealed off by the second vane. The enclosed gas is then compressed until the outlet valve opens against atmosric pressure. The outlet valve is oil-sealed. When the valve is open, a small amount of oil enters the suction chamber and not only lubricates it but also seals the vanes against the housing (stator).
