手拖或小四轮拖拉机上的柴油机曲轴油封渗漏问题具有普遍性,导致渗漏的因素众多,较为复杂。你处新买的长春—12型小四轮拖拉机飞轮油封漏油,我们分析可能是以下几种原因造成的: 1.油标指示器卡死,造成机油压力过高; 2.负压(阀)管不起作用,造成曲轴箱压力过高; 3.机油泵出口压力和流量过高; 4.油封唇口的质景不佳、维修安装方法不当。如果是第1、2种原因造成的,可修复油标指示器或负压(阀)管;如果是第3种原因,则必须增加机
Trailer or small four-wheel tractor diesel engine crankshaft oil seal leakage is widespread, leading to leakage of many factors, more complicated. Your newly purchased Changchun -12 small four-wheel tractor flywheel oil seal leakage, our analysis may be caused by the following reasons: 1. Oil indicator stuck, resulting in excessive oil pressure; 2. Negative pressure (valve ) Tube does not work, causing the crankcase pressure is too high; 3. The oil pump outlet pressure and flow is too high; 4. Oil seal lip poor quality, repair and installation improper. If it is caused by the 1st and 2nd reasons, the oil indicator or negative pressure (valve) pipe can be repaired; if it is the 3rd reason, you must increase the machine
