This year’s 【Daily Question】 is divided into three categories: screw refrigeration compressors, refrigeration systems, and oil circuits, 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; by doing 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 airflow regulation mechanism (5): Stepless adjustment of the screw compressor from 0 to 100% – what range of load levels is optimal for operation? ； State the volume ratio of compressors you have seen. Answer: Based on the relationship between the spool position and exhaust volume shown in the diagram below, it is clear from the DA curve that the spool performs better when at a position above 50%! Internal volume ratio: 1.5, 2.6, 3.6, 4.0, 5.0, etc. ============================== High-quality promotions: Mechanical equipment——Videos on the repair 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 Quinton 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 Maekawa MYCOM screw compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=
It is more economical to operate at a load of over 40%
It is more economical to operate at a load of over 40%
It is more economical to operate at a load of over 40%.
It is best to maintain the load at around 85%, which enables safe, stable, and long-term operation. The cost-effectiveness is high at this time, and efficiency is excellent.
