连杆螺栓因受拉应力疲劳断裂是其主要的断裂形式,但却是较为少见的制冷压缩机故障。本文就某冷库三号制冷压缩机(4AV—12.5)连杆螺栓断裂,并导致相关零部件严重损坏,以及曲轴曲柄销磨损与疲劳损坏的事故进行分析。 一 事故的发生及压缩机损坏程度 1994年6月8日凌晨1时50分,压缩机运转工发现,三号机声音异常,班长指示立即作紧急停车处理,即刻切断三号压缩机及
Connecting rod bolts due to tensile stress fatigue fracture is its main form of fracture, but it is relatively rare refrigeration compressor failure. This article analyzes the fracture of a connecting rod bolt of a refrigerating machine No.3 refrigeration compressor (4AV-12.5), resulting in serious damage of the related parts and the accident of the wear of the crankshaft pin and the fatigue damage. An accident and the compressor damage degree At 1:50 on June 8, 1994, the compressor operator found that the sound of No. 3 machine was abnormal, and the squad leader instructed to make an emergency stop immediately and cut off the No. 3 compressor and
