一、使用中出现的问题东德挖掘机水平轴上三个片式摩擦离合器经常产生漏气现象,主要是压缩空气从水平轴中心孔经A处通入风缸5,容易从大小活塞环16、17与风缸内表面处泄出,使气压不足。摩擦盘3压不紧摩擦片14,易产生打滑,这样一方面使挖掘机动作操纵不灵,另一方面经常打滑使摩擦片磨损严重,并产生热量,使橡胶密 First, the use of the problems East German excavators horizontal friction clutch on the three-chip often have leaks, mainly compressed air from the horizontal axis through the center hole A through the cylinder 5, easy to size piston ring 16 , 17 and the inner surface of the cylinder leak, so that lack of pressure. Friction plate 3 does not press the friction plate 14, easy to produce slippery, so that the excavator action on the one hand not working, on the other hand often slippery friction plate to wear and heat, so that the rubber seal
