What is a Rotary Vane Vacuum Pump?
A rotary vane vacuum pump is a kind of positive-displacement pump, which is one of the basic equipment for removing gas from sealed containers. Generally, the gap between the rotary vane and the pump cavity is sealed by oil, so the rotary vane vacuum pump is usually regarded as a kind of oil-sealed mechanism vacuum pump.
introduction to rotary vane vacuum pump
The rotary vane vacuum pump is one of the basic equipment for removing gas from sealed containers. A rotor is arranged in the pump chamber, and a rotary vane is arranged in the rotor slot. When the rotor drives the rotary vane to rotate, the rotary vane is closely attached to the chamber wall, and the inlet and exhaust ports are separated. The volume of the intake manifold is periodically expanded to inhale, and the volume of the exhaust chamber is periodically reduced to compress the gas. The exhaust valve is exhausted to obtain a vacuum. Its working performance consists of two parts: high pressure stage and low pressure stage. Its suction port is connected with vacuum equipment. When operating, the gas in the container is inhaled and discharged in large quantities. When the equipment is vacuumed, the high pressure stage exhaust valve is closed and the high pressure is closed. The gas at the stage inlet will be transferred to the second stage, and a certain vacuum can be obtained by inhaling and discharging the vacuum device through the second stage.
The rotary vane pumps play an important role in many industries, which can support other devices in order to complete operations. For example, rotary vane pumps are commonly used in the automotive field. With these pumps, various products, allowing movement of fluids, can be made by automakers, such as automatic transmissions, brakes, power steering systems, and more. These pumps can also be incorporated into dispensing machines for soft drinks and coffee. Furthermore, the rotary vane pumps can be used in laboratories and other industries as well.
Vacuum pump oil is a kind of lubricating oil specially developed for vacuum pumps on vacuum equipment, which is divided into mineral oil and synthetic oil. Vacuum pump oil is suitable for reciprocating booster pumps, mechanical booster pumps and oil-sealed mechanical vacuum pumps. It can also be used for various diffusion vacuum pumps. It is recommended for vacuum pumps in the fields of crafts, ceramics, chemistry, etc.
