liquid 1. Liquid back: When the refrigerant returned to the compressor is not a pure gas state, but contains liquid, the influence of the liquid refrigerant on the compressor is negative. If there is too much liquid, it may even cause liquid shock, even if there is no liquid shock, it will happen. Wet compression causes oil to run away.

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:
