近年来,我县有很多长白山-12型手扶拖拉机(发动机为X195柴油机),在使用中经常发生烧瓦的故障。为了排除故障,我们进行了多次分析、研究,并对转子式机油泵进行了试验,证明油泵没问题,经过检查,发现烧瓦是由如下原因造成: 1.使用中不经常保养、更换机油,当机油滤清器的滤网损坏后,机油内的杂质、铁屑等被吸入机油滤清器油管内,堵住油道,使机油泵泵不上润滑油引起烧瓦。 2.在拆装机油滤清器时,忘掉安装空心螺栓和滤清器油管接头处的密封铜垫圈,产生漏气,使机油泵泵不上油,而引起烧瓦。 In recent years, my county has a lot of Changbai Mountain -12 walking tractor (engine for the X195 diesel engine), in the use of frequent bushings failure. In order to troubleshoot, we conducted a number of analysis, research, and rotor type oil pump was tested to prove that the pump no problem, after inspection, found that the tile is caused by the following reasons: 1. The use of less regular maintenance, replacement of oil When the filter of the oil filter is damaged, the impurities in the oil, iron filings and the like are sucked into the oil filter oil pipe to block the oil passage, so that the oil pump does not cause the oil pump to cause burning of the oil. 2. When dismantling the oil filter, forget the installation of hollow bolts and filter pipe joints at the seal copper washer, resulting in leakage, so that the oil pump is not oil, causing the bush.
