This post was last edited by YORK Industrial Refrigeration on 2018-4-13 at 09:36. This year’s 【Daily Question】 is divided into three categories: screw refrigeration compressors, refrigeration systems, and oil circuit systems, aiming to provide a comprehensive understanding of refrigeration technology. (If you encounter something you don’t know or can’t answer, please actively look up information; as you do so, your skills will improve!) ) All participants in the comments on this post will receive 1-3 wealth points; those who give complete answers will get 10-15 points, with the validity period being two days. ============================== Screw refrigeration compressor oil circuit system (1): Which parts of the screw compressor require oil? What role does oil play in a compressor? Answer: Oil serves to lubricate the bearing areas. It also acts as a lubricant and sealant for the screw parts. In the case of shaft seals, oil functions as a sealant. Oil applies pressure to the balance piston in order to counteract the axial force exerted by the screw. As for the oil piston, oil applies pressure to push the slide valve or slider forward. ============================== Premium promotions: Mechanical equipment——Videos on the maintenance and adjustment of York compressors: https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1806833 Mechanical equipment——Maintenance procedures for York screw compressors: https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1806833 Mechanical equipment——Upgrading of York Quontum control centers: https://bbs.hcbbs.com/thread-1804837-1-1.html Mechanical equipment——Major repairs of GEA Grasox screw compressors: https://bbs.hcbbs.com/thread-1800467-1-1.html Mechanical equipment——Disassembly and maintenance of British HOWDEN screw compressors: https://bbs.hcbbs.com/thread-1832529-1-1.html Mechanical equipment——Disassembly and maintenance of Japanese MYCOM screw compressors: https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=

Compressor lubricant is used in the host, oil pipes, coolers, etc. Its function is to lubricate the moving parts of the compressor cylinders and the exhaust valves, as well as to provide rust prevention, corrosion protection, sealing, and cooling effects.
Oil is needed at the rotor to cool it down and provide lubrication

1. Lubrication of the male and female rotors, as well as for sealing and cooling purposes. 2. Injected into the balance piston to counteract axial forces. 3. Lubrication of the radial bearings. 4. On both sides of the stage piston, it enables unloading and loading. 5. On both sides of the slider piston, it is used to adjust the stage ratio
