我局使用的RAK-2A型铲车,在使用中,经常出现柴油机自动灭火的现象。据我们分析,其主要原因是由于进油孔和过滤筛太小,如遇油渣,过滤筛堵死,进油不畅,当发动机工作时,油泵不断供油,而油箱开关封闭不严,空气从油开关进人油管,经常漏气,因此使得柴油机自动灭火。 RAK-2A forklifts used by our bureau, in use, often appear automatic fire extinguishing diesel engine phenomenon. According to our analysis, the main reason is that because the oil inlet hole and the filter sieve are too small, in case of oil residue, the filter sieve is blocked and the oil enters poorly. When the engine is working, the oil pump keeps supplying oil while the oil tank switch is not closed tightly, Air from the oil switch into the tubing, often leaks, so that the automatic diesel fire extinguishing.
