Vanes are rotary discs that allow the creation of suction for the removal of air molecules from a vessel or a specific area. A rotary disc vacuum pump operates on a positive displacement pumping principle. It consists of a rotor mounted in a cylindrical housing.
What are vanes?A vane is part of a rotary vane vacuum pump. The rotary vane vacuum pump is characterized by oil-free operation and high operating reliability. Because they are oil-free, they are ideal for industrial applications requiring fast and reliable vacuum.
Operation dry-running rotary vane vacuum pump:A rotary vane vacuum pump operates on a positive displacement pumping principle. It consists of a rotor mounted in a cylindrical housing. A vane is also called a vacuum vane.
- The dry-running rotary vane vacuum pump consists of a cylindrical pump housing assembled with an electric motor.
- Inside the pump housing is an eccentrically arranged rotor with vacuum vanes.
- As the rotor rotates in the pump housing, the vacuum vanes move toward the pump housing wall (centrifugal force), creating chambers in the 360-degree circle.
- Air is drawn in, compressed and pushed out again.
- The pump sucks in this way allowing a vacuum to build up.
Types of vanesA vane is a turntable that allows the creation of suction for the removal of air molecules from a vessel, machine or specific area. These vacuum pumps are widely used for the food, pharmaceutical and medical industries.
There are different types of vanes:
- Carbon vanes
- Steel vanes
- Plastic vanes
Carbon vanes can only be used for dry-running vacuum pumps. Steel and plastic vanes are also suitable for oil-lubricated vacuum pumps. The service life of a vane depends, among other things, on the environment in which the dry-running vacuum pump is located. A wet, dirty, very hot or just cold environment can indeed shorten the life of the vane.
