当发动机工作了一定时间,轴瓦配合间隙超过了使用极限值后,进入轴瓦里的润滑油很快流失,不仅马力下降,而且极易发生烧瓦事故。 一看 看机油压力表是否过低。在机油泵等润滑系统各零部件工作均正常,使用的机油也符合当地季节要求的情况下,发动机的机油压力在额定转速下,长期低于正常压力值下限,或从机油压力表上几乎反映不出压力时,说明发动机主轴瓦、速杆瓦与轴颈配合间隙过大,机油渗漏严重,形不成机油压力。
When the engine is working for a certain period of time, the bearing bush with the gap exceeds the limit of use, the lubricating oil into the bushings quickly lost, not only the horsepower decline, but also prone to bush accident. A look at the oil pressure gauge is too low. In the lubrication of oil pumps and other components of the work are normal, the use of oil is also in line with the requirements of the local season, the engine oil pressure at rated speed, long-term below the lower limit of normal pressure value, or almost reflected from the oil pressure gauge No pressure, indicating the engine main bearing, speed lever shim and journal with the gap is too large, serious oil leakage, the shape of the oil pressure.
