I. Mechanical pumps
The main function of the mechanical pump is to provide the necessary pre-stage vacuum for the start-up of the turbomolecular pump. Commonly used mechanical pumps include mainly ...
Many vacuum process installations are equipped with a Roots pump on top of the pre-stage pump, both to increase the pumping speed and to improve the vacuum. However, the following problems are ofte...
The primary objective of a vacuum pump is to generate, maintain, or improve a vacuum state within an enclosed space. By removing air or other gases, the vacuum pump reduces the pressure within the ...
1. The number of fan blades is small, and the air volume generated is small.
2. The fan speed is low, the wind pressure and air volume are small.
3. The motor has high power and high current, r...
High vacuum gate valve has three driving modes:manual, pneumatic and motor-driven, which have the advantages of smooth action, small size, reliable use, good sealing performance and long life, etc....
