K-type diffusion pump and K-type metal oil diffusion pump are 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, need to be equipped with a front-stage pump. The K diffusion pump is applied to the electronics industry, chemical industry, atomic energy industry and space simulation test.
Two, K type diffusion pump working principle:
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.
