Choose vacuum pump according to metallurgical gas volume

Posted on Fri, 20 Jul 2018 01:54:55 +0000

A vacuum is a given space with a gas pressure below 101,325pa. In a vacuum, the pressure of the gas, the fineness is generally expressed in natural gas, the smaller the pressure value, the thinner the gas. There are many kinds of industrial vacuum pumps, pump performance test methods need to be t...

Gas rate of oil diffusion pump

Posted on Wed, 18 Jul 2018 02:43:31 +0000

The pumping speed of the oil diffusion pump remains unchanged within a wide range of inlet pressure. At this time, the pumping speed of the pump is independent of inlet pressure. However, under low and high inlet pressure, the pumping speed of the pump tends to decrease. In the low inlet pressure...
