1现存问题普通空压机4L-20/8,在日常的使用维护工作中,平衡和曲轴的固定设计上采用图1结构(曲轴体嵌入平衡铁防止位移,克服离心力靠2件M27螺栓固定,螺栓浇铅防退)。从长期使用来看,平衡铁压紧固定螺栓松脱,平衡铁飞出砸坏空压机机身事故时有发生。为杜绝设备损坏事故发生,浅谈 1 Existing Problems General air compressor 4L-20/8, in the daily use and maintenance work, the balance and the crankshaft fixed design using the structure of Figure 1 (crankshaft embedded in the balance iron to prevent displacement to overcome the centrifugal force by 2 pieces of M27 bolts, Bolt lead-back). From the long-term use point of view, the balance iron compression bolts loose, balance iron flying out smashed air compressor airframe accidents have occurred. In order to prevent equipment damage accidents, talk about
