【Mechanical Equipment Technology Edition】Daily Question 201803020: Screw Refrigeration Compressors — Basic Structure and Characteristics (2)
Thread Content
This post was last edited by YORK Industrial Refrigeration on 2018-3-22 at 08:18. 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 receive 10-15 points, with the validity period being two days. ============================== Basic structure and characteristics of screw refrigeration compressors (2): The diagram below shows a cross-section of a York screw compressor. The marked areas represent the energy regulation devices. What are the components of these devices? Answer: Energy indication mechanism, oil piston, slider, spring, slide valve guide rod, slide valve ============================== Premium promotions: Mobile equipment——Videos on the repair and adjustment of York compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1806833 Mobile equipment——Maintenance procedures for York screw compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1806833 Mobile equipment——Upgrading of York Quinton control centers https://bbs.hcbbs.com/thread-1804837-1-1.html Mobile equipment——Major repairs of GEA Grasso screw compressors https://bbs.hcbbs.com/thread-1800467-1-1.html Mobile equipment——Disassembly and maintenance of British HOWDEN screw compressors https://bbs.hcbbs.com/thread-1832529-1-1.html Mobile equipment——Disassembly and maintenance of Japanese Maekawa MYCOM screw compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=
Load solenoid valve, cylinder, piston, unload solenoid valve
Spool valve, oil piston, spool valve guide rod, energy indicator.
In order are the piston, spool valve, spring, and slider
Piston, inner sleeve, piston shaft, outer sleeve. The answer might not be professional enough. . .
The energy regulation device consists of an energy control valve and a unloading mechanism; the two are connected by oil pipes, and pressurized oil supplied by an oil pump is used as the power source. Three components: the stem valve-actuating mechanism, the cylinder push rod mechanism, and the oil distribution valve
Spool valve, cylinder piston, capacity indicator, oil pipeline, four-way valve or solenoid directional control valve
From left to right: energy adjustment piston, volume ratio spool, guide rod, energy adjustment spool
It consists of a slide valve, an oil piston, a slide valve push rod, end seats and an oil cylinder, as well as a compression spring.
In order are the piston, spool valve, spring, and slider
