1.如何恢复机油压力 135系列柴油机的机油压力值偏低并由此而引发事故,是较为常见的问题。笔者曾多次遇见此类情况,后经仔细分析和反复实践,发现这多半是由于卸压弹簧的毛病所造成。检查和恢复的方法如下: 卸下机油压力调节螺钉处的卸压弹簧,检查该弹簧的弹力(可用新弹簧与被检弹簧串联夹在台钳上进行压缩,观察他们压缩量的区别加以判断)。当旧弹簧不能再用而又无新弹簧可供更换时,可对旧弹簧采用本刊1993年第1期第29页“旧弹簧修复”一文所介绍的方法进行处理。如果卸压弹簧弹力正常或更
1. How to restore the oil pressure 135 Series diesel engine oil pressure is low and thus lead to accidents, is a more common problem. I have repeatedly met such a situation, after careful analysis and repeated practice, found that most of the problems caused by the pressure relief spring caused. Check and restore as follows: Remove the oil pressure adjusting screw at the pressure relief spring, check the elastic force of the spring (available new spring and the inspected spring clamp in the vise on the compression, to observe the difference between their compression to be judged) . When the old spring can not be reused and no new spring is available for replacement, the old spring may be treated in the manner described in our first edition, page 29, “Old Spring Repair.” If the relief spring elastic normal or more
