我们在Ⅰ号泵检修中,发现21起由于放油螺塞顶死传动盘等零件引起的飞车事故。调速器放油螺塞(标准的为M8×10)过长或密封垫圈漏装、垫圈厚度太薄,均会使螺塞顶在传动盘等零件上,导致传动盘与传动轴套之间的缓冲橡胶块扭断,造成传动盘不随传动轴套一起转动,引起飞车。尤其在突然减小负荷 In our overhaul of pump Ⅰ, we found that there were 21 flying accidents caused by the components such as the top of the dead-end transmission disk on the oil drain plug. Governor drain plug (standard M8 × 10) is too long or missing gasket gasket, washer thickness is too thin, will cause the screw plug on the drive plate and other parts, resulting in the drive plate and the drive sleeve between The buffer rubber block twists and turns, resulting in the drive plate does not rotate with the drive sleeve, causing the car. In particular, suddenly reduce the load
