This post was last edited by YORK Industrial Refrigeration on 2018-3-29 at 09:44. 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.) ============================== Answer: Screw refrigeration compressor gas flow control mechanism (1): What are the main components of the energy control mechanism? I. Energy regulation indicators: disc type and rod type. II. Oil circuits and energy regulation control valves: manual four-way valves and electromagnetic directional valve assemblies. III. Energy regulation actuators: spools, sliders, spool guide rods, springs, oil pistons, and oil cylinders. ============================== 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 Grasso 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=
Energy regulation mechanisms, bearings, couplings, etc
What are the main components of an energy regulation mechanism? Energy indicator mechanism, oil piston, slider, spring, spool guide rod, spool
The gas flow rate adjustment mechanism consists of three parts: the first part includes a slide valve, a slide valve stem, an oil piston, a hydraulic cylinder, a compression spring, and end seats; the second part is the gas flow rate adjustment indicator; the third part is the oil circuit and the gas flow rate adjustment control valve.
It consists of a slide valve, an oil cylinder, an oil piston, a four-way solenoid directional control valve, and oil pipelines
It consists of three parts: fuel supply, control, and actuator.
It is mainly composed of cylinders, oil pistons, tie rods, rotating rings, push rods, springs, as well as oil distribution valves.
The energy regulation mechanism consists of a slide valve, an oil cylinder, an oil piston, a connecting rod, a return spring, a four-way directional control valve, oil pipelines, and an energy indicator.
Indicator mechanism: Energy indicator. Control mechanism: Four-way valve, connection piping. Actuating mechanism: Cylinder, oil piston, slide valve, spring, slide valve rod, slider.
The energy regulation mechanism of a refrigeration compressor mainly consists of an oil cylinder, an oil piston, tie rods, a rotating ring, a push rod, springs, and an oil distribution valve
