The so-called vacuum refers to a gas state with a pressure lower than 101325Pa in a given space. In the vacuum state, the lean degree of gas is usually expressed by the pressure value of the gas. Obviously, the smaller the pressure value, the thinner the gas. There are various vacuum pumps in the industry. There are prescribed test methods for the performance of various pumps. The main parameters are:

The machine used to generate compressed air is also called compressed air machine, also called air compressor, or air compressor for short. The motor directly drives the compressor to make the crankshaft produce rotational movement, drive the connecting rod to make the piston produce reciprocating motion, and cause the cylinder volume Variety.
