1981年12月11日晚,我厂供土霉素专用的1、3号4L-20/8型空压机一级缸同时发生爆炸,经济损失约5600元。经调查、分析,鉴别,造成爆炸原因是: 1.未严格控制加油量(爆炸后污油甚多),油耗比规定多得多。机身油(被臥列十字头导轨底部回油孔严重堵塞,而刮油环刮下来油不能回到曲轴箱内)通过活塞杆填料函压进气缸,长期积存,在高温下积碳。此外,空压机吸气口所处环境低
The evening of December 11, 1981, I plant dedicated oxytetracycline 1,3 No. 4 4L-20/8 air compressor cylinder explosion at the same time, the economic loss of about 5,600 yuan. After investigation, analysis, identification, the cause of the explosion is: 1. Not strictly control the amount of fuel (after the explosion much dirty oil), fuel consumption much more than the provisions. Oil in the fuselage oil is blocked by the oil return hole at the bottom of the cross-head guide rail, and the scraping ring scrapes off the oil and can not return to the crankcase. Press into the cylinder through the stuffing box of the piston rod for long term storage and carbon deposition at high temperature. In addition, air compressor inlet environment is low
