活塞式空气压缩机是广泛采用的一种机器。着火爆炸是其最严重的事故。这里就一件空气压缩机爆炸事故作一简要介绍和粗浅分析。供大家参考。 一、事故的概况 西宁某钢厂一台7L-100/8型活塞式空气压缩机,已安装使用七年多。七六年三月大修后,经调试于一个星期天下午一时三十分开车,三个小时以后,于四时二十八分突然爆炸。机房内顿时充满了黑烟。 爆炸后发现:一级气缸完好无损; 二级气缸的四只排气阀附近的一块缸壁及排气管均爆掉;排气管与缸体的连接螺栓被拉断;阀盖紧固螺栓多数拉断;阀盖飞出,打到房顶上;排气管摔落在机器左侧,弯管凸部摔凹;排气管内有约5毫米干燥积碳;残缸内有许多润滑油,缸壁有一层油膜;余隙阀室内充满水及油;排
Piston air compressor is a widely used machine. Fire explosion is its most serious accident. Here for a brief summary of the air compressor explosion accident and superficial analysis. For reference. First, the accident profile Xining, a steel mill 7L-100/8-piston air compressors, has been installed to use more than seven years. After its overhaul in March 1976, it was commissioned to drive on a Sunday afternoon at 1.30 pm and suddenly exploded at four-two-eight hours after three hours. Machine room suddenly filled with black smoke. Explosion was found: a cylinder intact; two cylinder exhaust valve near the four walls and an exhaust pipe burst; exhaust pipe and the cylinder connecting bolt is pulled off; bonnet captive bolts Most pulled off; bonnet fly out, hit the roof; exhaust pipe fell on the left side of the machine, elbow bend concave; exhaust pipe has about 5 mm dry carbon deposition; residual lint cylinder has many lubricants , Cylinder wall has a layer of oil film; clearance valve room filled with water and oil; row
