1.绞盘漏油一台GJT112型推土机在施工中出现钢丝绳绞盘处渗油的现象。将钢丝绳全部拉出后发现,液压油是从绞盘座上螺栓处渗出的,且在加大油门时,渗漏较快,怠速时几乎不渗油。初步分析可能是螺栓松动或垫片损坏所致,但更换垫片拧紧螺栓后试机,故障依旧。进一步分析液压原理图认为,原因可能是回油不畅、背压较大
1. Winch leakage A GJT112 bulldozer appeared in the construction of wire rope winch at the phenomenon of oil leakage. The wire rope pulled out and found that the hydraulic oil is from the winch screw seat at the seepage, and increase the throttle, the leakage faster, almost no oil at idle. Preliminary analysis may be caused by loose bolts or gasket damage, but after replacing the gasket Tightening bolts test machine, the fault still. Further analysis of hydraulic schematic that may be due to poor return oil, back pressure larger
