1.发动机转速增加,油压反而降低一495K型柴油机,三号保养后使用约100小时,突然出现一种怪现象:怠速时,机油压力为0.2兆帕(2公斤力/厘米~2);而中速以上时,油压只有0.1兆帕(1公斤力/厘米~2)。经过检查,发现一大片铅油贴在集滤器滤网中间。这样,当柴油机转速低时,机油吸力小,滤网因有弹性而张开,可以吸入机油。当柴油机转速增高时,机油泵吸力很大,滤网因脏被吸起,其上的铅油片恰好堵住进油孔,致使机油泵进
1. The engine speed increases, but the hydraulic pressure is reduced by 495K diesel engine. After maintenance for 100 hours on the 3rd, a strange phenomenon suddenly occurs. At idle, the oil pressure is 0.2 MPa (2 kgf / cm ~ 2). Above medium speed, the hydraulic pressure is only 0.1 MPa (1 kgf / cm ~ 2). After inspection, I found a large piece of lead oil stuck in the middle of filter strainer. In this way, when the diesel engine speed is low, the oil suction is small, the filter is open due to elasticity, which can inhale the oil. When the diesel engine speed increases, the suction pump is very large, the filter is dirty due to be sucked, the lead on it just plug the oil into the hole, causing the oil pump
