东风_4型机车静液压系统软管,在装配管接头时,须掌握合适的扣压量。如扣压量过大,就容易出现钢丝层断或锁紧环断裂的现象。相反,扣压量小,就出现管接头芯处渗漏或接头脱落的现象。为了使液压软管接头在使用过程中安全、可靠和耐用,我们认为应正确掌握软管接头的扣压程度。东风4型机车静液压软管的扣压程度,完全取决于锁紧环内径的大小。我段采用的测量计算方法如下(见图1)。
Dongfeng _4 locomotive hydrostatic system hose, pipe fittings in the assembly, to grasp the appropriate amount of buckle. If the amount of buckling is too large, it is easy to break the wire layer or the phenomenon of breaking the locking ring. In contrast, the amount of buckling is small, there is leakage at the connector core or connector off phenomenon. In order to make the hydraulic hose fittings safe, reliable and durable during use, we think that the degree of pressure on the hose fittings should be correctly grasped. Dongfeng 4 locomotive hydrostatic hose buckling degree depends entirely on the size of the locking ring diameter. The measurement method used in my paragraph is as follows (see Figure 1).
