The single-stage oil-lubricated rotary vane vacuum pump is a positive displacement oil-sealed mechanical vacuum pump, with an independent rotor-vane pump chamber arranged inside. The rotor in the cylinder is equipped with two (or three) vanes, which are pressed against the inner wall of the pump chamber by centrifugal force, dividing it into independent variable-volume chambers.
The gas directly enters the pump chamber to complete a single compression, and is discharged from the exhaust port after compression. The complete machine uses vacuum pump oil circulation for lubrication and sealing; an oil mist separator is configured to achieve oil-gas separation and oil recycling; a shutdown check valve blocks medium backflow and protects the vacuum-side chamber.
The single-stage compression structure brings stable and reliable pumping speed and vacuum degree. The standard gas ballast valve can handle a small amount of water vapor. It is widely used for standalone vacuum pumping and can also be used as a backing pre-pumping pump for Roots pumps and molecular pumps.
The Leynow series single-stage oil-lubricated rotary vane vacuum pump is suitable for industrial production, scientific research experiments, and vacuum unit matching scenarios with moderate vacuum requirements. Standalone or backing pump solutions can be provided according to process requirements.
The single-stage oil-lubricated rotary vane vacuum pump is an oil-sealed mechanical vacuum pump with single-stage pump chamber compression. The working pressure range is typically 101325~1×10⁻¹ Pa, making it a medium vacuum generation equipment.
