Mentioned screw unit for many enterprises we use for the refrigeration system we are not unfamiliar, it is the core of our refrigeration system components, and when it running for a period of time requires daily maintenance and maintenance work of screw machine enterprises, in order to ensure the normal operation of the better, to create more benefits for our business. In order to have a comprehensive grasp of the screw unit, which requires our professional staff must be on the structure and working principle of screw machine needs to have a comprehensive understanding, today Xiaobian Dongxing summarizes some of the points, and everyone to share.
At present, the fuel injection screw machine is one of the main types of refrigeration compressors. Screw machine is divided into two types of twin-screw and single screw, twin-screw machine is commonly known as screw compressor. We say the screw machine maintenance, that is, the maintenance of twin-screw machine.
Screw machine is usually by Yang rotor, Yin rotor, airframe, sliding bearings, thrust bearings, shaft seal, balance piston and so on. Understand the composition of the screw machine in the screw machine maintenance when it can be more smoothly. A pair of rotors, the positive rotor and the negative rotor, are arranged in the cylinder whose cross section is a double circle. The positive rotor and the negative rotor cooperate to carry out the process of suction, compression and exhaust so as to complete the running process of the screw machine.
If you can do the daily maintenance and maintenance of the screw unit, you can effectively extend the service life of screw machine, so enterprises must carry out regular maintenance work on the screw machine.
