Compared with the K series metal oil diffusion pump, the TK type metal oil diffusion pump can increase the pumping speed by 30-50%. It is also used in the electronics industry, chemical industry, atomic energy industry, and space simulation tests. TK type metal oil diffusion pump is used in high vacuum and ultra high vacuum to remove the gas that does not seriously harm the working liquid in the high vacuum system. It cannot directly exhaust to the atmosphere and requires a foreline pump.
Working principle of TK metal oil diffusion pump: After the current stage pump draws the pre-vacuum in the diffusion pump to about 10pa, the working fluid with low saturated vapor pressure at room temperature is heated by the heater, and the oil vapor generated upwards along the steam duct The movement is directed by several stages of nozzles and ejected at high speed, bringing the gas diffused in the oil vapor to the front stage. Excluded from the foreline pump to the atmosphere, after the oil vapor is sprayed on the pump wall, after cooling, it flows back to the bottom of the pump, thus repeating the work to achieve the purpose of high vacuum.
1. Large pumping speed (compared to K series pumps, the pumping speed of TK and KT pumps can be increased by 30-50%)
3.Long service life
It is often used in situations that require high pumping time and large exhaust volume
