【Mechanical Equipment Technology Edition】Daily Question 20171010: Assembly of Screw-Type Refrigerant Compressors (2)
Thread Content
This post was last edited by YORK Industrial Refrigeration on 2017-10-13 at 08:34. 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. Identify the names of the tools shown in the image. Extra question (state the role of each tool during compressor assembly): Dial indicator, vernier caliper, feeler gauge, micrometer. Dial indicator: concentricity, assembly clearance, inner diameter, etc. Vernier caliper: shaft diameter. Feeler gauge: assembly clearance. Micrometer: shaft diameter. ================================ Premium promotions: Mechanical equipment—maintenance procedures for York screw compressors http://bbs.hcbbs.com/thread-1806833-1-1.html Mechanical equipment—upgrading of York Quinton control centers http://bbs.hcbbs.com/thread-1804837-1-1.html Mechanical equipment—major repairs of GEA Grasso 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
Dial indicator, vernier caliper, feeler gauge, micrometer. A dial indicator should be used for alignment and measuring the rotor’s play ； A vernier caliper can measure the outer diameter of shafts and the inner diameter of bearings ； Use a feeler gauge to measure the gap between the rotor and the front and rear wall panels ； Use a micrometer to measure the thickness of the shimming pad. I’m speaking based on the approach used when maintaining rotary vane blowers.
