Cryogenic Pump of Overview A cryogenic pump is a type of pump that uses a low-temperature surface below 20K to condense gas molecules for pumping, and is currently the highest limit vacuum pump. It is mainly used in large-scale vacuum systems, such as high-energy physics, preparation of supercond...

Cryogenic pumps are mainly divided into the following categories Cryogenic condenser pump: Uses low-temperature surface condensation of gas molecules to achieve pumping, suitable for high vacuum environments. Cryogenic adsorption pump: Using adsorbents (such as activated carbon) to adsorb gas mol...

Low-temperature liquid pump of operating temperature range The working temperature range of low-temperature liquid pumps is generally between -185 ℃ and -269 ℃, which is affected by factors such as materials and sealing performance. 1.Low Temperature Liquid Pump of Characteristics Low temperature...

Screw vacuum pump The ultimate vacuum degree is the point on the pumping speed curve where the pumping speed is 0. It should be emphasized that the ultimate vacuum is not the higher the better, or this point is not very important. What is important is the pumping inflection point and the slope be...
