This post was last edited by YORK Industrial Refrigeration on 2017-11-13 at 08:25. Starting from now, in order to enhance communication among users, a 【Daily Question】 activity has been launched on the Mechanical Equipment Technology forum. We hope everyone will participate actively to progress and improve together! ! ! Rewards: 3 points for active participation, 10-15 points for correct answers. This question is valid for two days; no scoring will be given after that period. In the previous discussion, we talked about the factors that affect the gas delivery coefficient, and one of the most significant factors is gas leakage. What are the pathways through which gas leaks inside the compressor? Leakage losses are divided into two types: one is internal leakage (which directly affects efficiency) ； One type is external leakage (which directly affects the gas flow rate), which occurs when gas leaks along the outer circumference of the rotor and the inner wall of the machine, at the contact points between the rotor and other components, or along the gap between the rotor end face and the end cover. http://attach01.hcbbs.com/forum/201711/04/082814nzk7cktqktql92kn.jpg http://attach01.hcbbs.com/forum/201711/04/082815jvkvejo0k05fjoe5.jpg ================================ Premium promotions: Mechanical equipment——York screw compressors: maintenance procedures https://bbs.hcbbs.com/thread-1806833-1-1.html Mechanical equipment——Upgrading York Quontum control centers https://bbs.hcbbs.com/thread-1804837-1-1.html Mechanical equipment——Major repairs for GEA Grauso 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 Maekawa MYCOM screw compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1786445
Mechanical seal leakage between the rotor and the front and rear wall panels, as well as between rotors

Leakage refers to the escape of gas through gaps; internal leakage is the leakage that occurs within the elemental volume isolated from the intake pipe. Internal leaks mainly include those between the rotor and the front and rear wall plates, between rotors, and those from the mechanical seal.
