一、为什么有的柴油机油压表没有压力,指针不动?主要是由于对柴油机润滑系统保养不够造成的。柴油机中的机油具有润滑作用外,还有清洗杂质和冷却的作用。如果长期不换机油,机油就会失去润滑的能力,并且由于润滑系统内金属屑和杂质的增多,会把机油吸油器的滤网和机油过滤器堵死,整个润滑系统也不再循环,油压表也不动 First, why some diesel pressure gauge no pressure, the pointer does not move? Mainly due to inadequate maintenance of the diesel engine lubrication system. Diesel engine oil lubrication, but also the role of cleaning impurities and cooling. If you do not change the long-term oil, the oil will lose the ability to lubricate, and due to the increase in the lubrication system of metal shavings and impurities, the oil filter and oil filter will be blocked, the entire lubrication system is no longer recycled, the oil Pressure gauge does not move
