我们在下乡工作中,碰到几例由于柴油机倒转而造成的工伤事故,其中有打肿手臂的,有打掉牙齿的,有打伤眼睛的等。因此,切不可忽视柴油机的倒转。柴油机倒转时,进排气行程顺序颠倒,机油泵不供油,对使用惯性油浴式空气滤清器的柴油机,倒转时空滤器油盘中的油往往会被排气冲出,此时柴油机声响极不正常,机件极易磨损。造成柴油机倒转的原因有:(1)供油时间过早,活塞尚未到达应该供油位置之前即爆发作功,将活塞推回,致使曲轴倒转;(2)当柴油机因负荷过重而熄火时,分离离合器后,由于飞轮的惯性作用而倒
In our work in the countryside, we encountered several accidents involving work-related injuries caused by the reversal of the diesel engine, among which swollen arms, broken teeth and wounded eyes were encountered. Therefore, we must not ignore the reverse engine. Diesel reverse, the intake and exhaust stroke reversal sequence, the oil pump does not supply oil, the inertia oil bath air filter diesel engine, inverted space-time filter oil pan oil often will be out of the exhaust, then the sound of diesel Very abnormal, mechanical wear easily. Reasons for causing the engine to reverse are: (1) fuel supply time is too early, the piston has not yet reached the oil supply position before the outbreak of work, pushing the piston back, resulting in crankshaft reversal; (2) when the diesel engine is overloaded due to turn off , After separating the clutch, due to the inertia of the flywheel and down
