离心式压缩机的工作原理：
Working principle of centrifugal compressor:
当叶轮高速旋转时，气体随着旋转，在离心力作用下，气体被甩到后面的扩压器中去，而在叶轮处形成真空地带，这时外界的新鲜气体进入叶轮。
When the impeller rotates at a high speed, the gas rotates with it. Under the action of centrifugal force, the gas is thrown into the diffuser behind, and a vacuum zone is formed at the impeller. At this time, fresh gas from the outside enters the impeller.
叶轮不断旋转，气体不断地吸入并甩出，从而保持了气体的连续流动。
The impeller rotates constantly, and the gas is constantly sucked in and thrown out, thus maintaining the continuous flow of gas.
主要优点：输气量大而连续，运转平稳；机组外形尺寸小，重量轻，占地面积少；设备易损部件少，使用期限长，维修工作量小；由于州苗木 保定通风管道 丝网立柱模具 尼龙输送带 保定空压机 高碑店养老院很高，可以用汽轮机直接带动，比较安全，容易实现自动控制。
Main advantages: large and continuous gas transmission, stable operation; The size of the unit is small, the weight is light, and the floor area is small; The equipment has few vulnerable parts, long service life and small maintenance workload; Because of the high speed, it can be directly driven by the steam turbine, which is relatively safe and easy to realize automatic control.
