This post was last edited by YORK Industrial Refrigeration on 2017-10-20 at 08:33. Starting today, in order to enhance communication among users, we have launched the \"One Question per Day\" activity on the Mechanical Equipment Technology forum. We hope everyone will participate actively to progress and improve together! ! ! Rewards: 3 wealth points for active participation, 10-15 wealth points for correct answers. This question is valid for two days; no scoring will be given after that period. As shown in the figure below, which part, the blue one or the red one, is the spool and which one is the slider? Please also explain their functions Red slide valve, blue slider: The slide valve is used to adjust the compressor capacity; the slider is used to adjust the compression ratio of the compressor. ================================ Premium promotions: Mechanical equipment——York screw compressors: Maintenance procedures http://bbs.hcbbs.com/thread-1806833-1-1.html Mechanical equipment——Upgrading York Quinton control centers http://bbs.hcbbs.com/thread-1804837-1-1.html Mechanical equipment——Overhaul of GEA Grasox screw compressors http://bbs.hcbbs.com/thread-1800467-1-1.html Mechanical equipment——Disassembly and maintenance of British HOWDEN screw compressors http://bbs.hcbbs.com/thread-1832529-1-1.html Mechanical equipment——Disassembly and maintenance of Japanese Maekawa MYCOM screw compressors http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1786445

Red is the [sliding valve], blue is the [slider]
Blue slider (content volume ratio spool), red energy spool. Valves and sliders are generally used in screw compressors to regulate the compressor’s load; when the slide valve opens, the compressed medium is returned to the inlet. Sliding valve regulation; it is the external pressure ratio ； Adjustable slider for the volume ratio of the content ；
Blue is the spool, red is the slider
Red is the spool, blue is the slider. The main function of the slide valve is to control the flow direction of the fluid ； The main function of the slider is to adjust the volume ratio of the compressor.
The blue one is the slider, which is used to adjust the volume ratio of the compressor. Red indicates that the slide valve is used to regulate flow and adjust the amount of cooling capacity
Red is the spool, blue is the slider； The slide valve is used to regulate flow, similar to backflow, while the slider is used to adjust the pressure ratio, namely the so-called volume ratio, primarily by adjusting the working length of the rotor
