在修理压缩机时,对吸排气阀检修的重要性,已在82年12月份第4期概述过,在此不再重复。近来我国新建的大、中型冷库,基本上采用8ASJ17型双级氨压缩机,因为它具有结构紧凑,占地面积小,产冷量大,运转平稳等优点。我公司5千吨冷库亦采用此机器,现对该机器的吸、排气检修方法分述如下: 一、吸气閥的检修拆去气缸盖,如图1所示,取出假盖(安全块)弹簧及排气阀部件,卸去导向圈上的6只六角紧固罗钉,取出导向圈及外阀座,就看到座落在气缸套端面上的吸气阀片,在这缸套
The importance of servicing intake and exhaust valves when repairing compressors was outlined in Issue 4, December, 82 and will not be repeated here. Recently, China’s newly built large and medium-sized cold storage, basically using 8ASJ17-type two-stage ammonia compressor, because of its compact structure, small footprint, large capacity, smooth operation and so on. My company 5 tons of cold storage also use this machine, now the machine suction, exhaust maintenance methods are described below: First, the suction valve maintenance Remove the cylinder head, shown in Figure 1, remove the fake cover (safety block ) Spring and exhaust valve parts, remove the six hexagonal fastening screw guide ring, remove the guide ring and the outer valve seat, you can see is located in the cylinder liner on the suction valve tablets in the cylinder liner
