Regarding the inlet medium temperature of air-cooled Roots vacuum pumps
Thread Content
Air-cooled Roots vacuum pumps have specific requirements regarding the inlet temperature. I would like to ask what effects an elevated inlet temperature can have on the pump. Thank you
The best approach to such issues is to use the device’s user manual as a standard; for conditions that go beyond what is specified there, it is necessary to consult the device manufacturer. Because in addition to process-related factors, pumps also involve aspects related to the material of the equipment and mechanical fit.
The key question is: how high is this higher value? Excessively high temperatures can cause the rotor to expand due to heat, leading to friction between the end surfaces and subsequent jamming!
How high is the temperature? Compression releases heat. It is best to cool the incoming gas in advance, so that some of the material can condense
