Oil diffusion pump price

The oil diffusion pump should also be applied to electronic industry, chemical industry, atomic energy industry and space simulation test. Oil diffusion pump is used for high vacuum and ultra-high vacuum pumping high vacuum system without serious harm to the working fluid gas, it can not directly exhaust to the atmosphere, the need to equip the front pump.

Oil diffusion pump structure:

The oil diffusion pump is mainly composed of pump body, diffusion nozzle, steam conduit, oil pan, heater, diffuser, cooling system and jet nozzle.

The working principle of oil diffusion pump:

The current stage pump pumps the diffusion pump into the pre-vacuum of about 10 pa, and the working fluid with low saturated vapor pressure at room temperature is heated by a heater. The generated oil vapor moves upward along the steam duct, directed by several stages of nozzles and spews out at high speed, bringing the gas diffused in the oil vapor to the front stage. The oil vapor is ejected into the air from the front stage pump. After the pump wall is cooled, the oil vapor flows back to the bottom of the pump and repeats its work to achieve high vacuum.


Oil diffusion pump price:

The price of oil diffusion pump depends on the type, structure and technology of vacuum pump. If you don't know the type, you can refer to this.


The vacuum is achieved by ribbed vacuum pump. Different types of pumps, it has a certain working conditions and scope, in the selection of vacuum pumps, we should fully consider its characteristics and specifications, and from the design system of the following four conditions.


1. the volume (including piping) and productivity requirements of vacuumed containers.


2. the degree of vacuum required.


3. the types of gases drawn.


4. the bleed and leakage of work and system during work.
