  1. Pressure of stainless steel vacuum pump For the knowledge of stainless steel vacuum pump, I believe you have a certain understanding, in order to have a better use of it, we should understand its calculation method, the following is a brief introduction for you. Vacuum degree = atmospheric pressure absolute pressure (atmospheric pressure is generally 101325pa, the ultimate absolute pressure of water ring vacuum pump is 3300pa, and the limit absolute pressure of vane vacuum pump is about 10Pa) 1. Limit relative pressure: the relative pressure is how much lower the measured intern
