What is a rotary vane vacuum pump?

A rotary vane vacuum pump in its simplest definition is a type of pump technology that enables the compression of air inside the pump chamber to create suction for the removal of air molecules from a vessel or area. Rotary vane vacuum pump works on a positive-displacement pumping principle.

Structure description of rotary vane vacuum pump

The rotary vane vacuum pump is a kind of positive displacement pump, which continuously operates the rotary vane in the pump chamber to inhale and compress the gas, and finally discharge it through the exhaust port. The pump is mainly composed of stator, rotor, rotary vane, etc. The rotor is eccentrically installed into the stator cavity. There are two rotary vanes in the rotor slot, and the rotary vane spring is placed between the two rotary vanes. The inlet and exhaust ports on the stator are separated into two parts by the rotor and the rotor. When the rotor rotates in the stator cavity, under the combined action of the spring tension and its own centrifugal force, the end of the rotary vane slides against the inner wall of the pump cavity, periodically expanding the cavity volume on the air inlet side and inhaling gas. Gradually reduce the volume of the exhaust port, compress the inhaled gas, and then discharge it from the exhaust port to achieve the purpose of pumping.

Frequently Asked Question

Do you have any question?

Rotary vane vacuum pump works on a positive-displacement pumping principle. The design consists of a rotor, which is mounted eccentrically inside a cylindrical housing or stator. Blades, mounted inside the rotor, move in and out due to centrifugal force following the internal surface of the housing.

The air is injected into the compressor through a valve, where it is contained between the rotor and the chamber wall, located in a chamber. As the rotor turns, the air becomes compressed, and the volume decreases.

Rotary pumps are commonly used for pumping high viscosity liquids such as oil including in handling lube oil and fuel oil in engine rooms. They are typically classified based on the type of rotating element they utilise.
