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 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...
The helium mass spectrometer leak detector is based on mass spectrometry technology and employs the helium tracer method for leak detection. Due to its high precision and reliability, it has become...
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...
TRP Double stage rotary vane vacuum pump is one of the fundamental vacuum acquiring equipment in vacuum applications.which is widely used in scientific research and teaching the require high or low...
