2、離心式壓縮機的工作原理？
2. Working principle of centrifugal compressor?
一般來說，提高氣體壓力的主要目標就是增加單位容積內氣體分子的數量，也就是縮短氣體分子與分子之間的距離，為了達到這一目標，采用氣體動力學的方法，即利用機械的作功元件（高速回轉的葉輪），對氣體作功，使氣體在離心式的作用下壓力得到提高，同時動能也大為增加，隨后在擴壓流道內這部分動能又轉變為靜壓能，而使氣體壓力進一步提高，這就是離心式壓縮機的工作原理。
Generally speaking, the main goal of increasing gas pressure is to increase the number of gas molecules per unit volume, that is, to shorten the distance between gas molecules. In order to achieve this goal, the method of gas dynamics is adopted, that is, the mechanical work element (high-speed rotating impeller) is used to work on the gas, so that the gas pressure is increased under the action of centrifugal The kinetic energy is also greatly increased, and then in the diffuser, this part of kinetic energy is converted into static pressure energy, and the gas pressure is further increased. This is the working principle of centrifugal compressor
