What are the types of vacuum pump

How many types of vacuum pumps are there

There are two types of vacuum pumps according to the working principle, and three types of vacuum pumps according to vacuum. In the first category, there are six subcategories under two main types. In the second category, there are four subcategories under three main types.

What are the types of vacuum pump

According to the working principle, the gas-delivery vacuum pump can be divided into rotary vane, slide valve, fixed vane, trochoidal, multi-chamber rotary vane,dry screw, liquid ring, roots vacuum pump, traction molecular pump, turbo molecular pump, compound molecular pump, liquid jet vacuum pump, gas jet vacuum pump, steam jet vacuum pump, self-purifying diffusion pump, fractional diffusion pump, diffusion injection pump, ion transport pump.

The gas-capture vacuum pump can be divided into adsorption pump, getter pump, evaporation ion pump, sputtering ion pump, cryogenic pump.

According to vacuum, the vacuum pump can be divided into slide valve vacuum pump, rotary vane vacuum pump, roots vacuum pump.

What is the work of vacuum pump

Vacuum pump is to provide a vacuum environment for experimental equipment through removing air out of the equipment with vacuum. A vacuum environment could guarantee the pressure and pure vacuum that operation process needs.

What is the use of vacuum pump

Vacuum pump applications include pharmaceuticals, pesticides, cosmetics and additives for cleaning hygiene products, soaps and synthetic detergents, surfactants, printing inks and their additives, adhesives, photosensitive materials, water treatment agents and carbohydrate flocculants, papermaking aids agent, leather auxiliary agent, mineral flotation agent, casting chemical, metal surface treatment agent.

What is the principle of vacuum pump

Vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to evacuate the pumped container to obtain a vacuum. The principle is to use an eccentric rotor to form a volume change in the pump cavity through the rotation to expel the gas from the pump. During the suction process, the volume of the suction cavity increases and the vacuum decreases, and the gas in the container is sucked into the pump cavity. During the exhaust process, the volume becomes smaller and the pressure increases, and finally the sucked gas is discharged out of the pump through the oil seal.
