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....
The molecular pump is a vacuum pump that uses a high-speed rotor to transfer momentum to the gas molecules so that they gain directional velocity and are thus compressed, driven towards the exhaust...
1. Flange connection
This is the most commonly used form of connection in valves. According to the shape of the joint surface, it can be divided into the following categories:
● Smooth type: it is ...
Sometimes, the demand for vacuum in enterprise production requires multiple vacuum pumps to be connected in series to form a vacuum unit to meet the requirements. In a stable and reliable vacuum sy...
The scroll vacuum pump evolved from the scroll compressor. Its structural principle was first invented by the French engineer Cruex in 1905, but due to technological limitations at the time, it was...
