①一台195-1型柴油机连续3次烧瓦,仔细观察发现,该机刚开始工作时,机油压力正常,工作一段时间后,机油压力降为零。停机休息一会儿再起动,机油压力又正常。工作一段时间后,机油压力又降为零。拆检后发现,机油中进入了碎树叶和铁屑。经分析认为,柴油机工作一段时间后,机油中的杂质就会吸附在吸油盘的滤网上,堵塞机油通道,使机油压力降为零。停机后,机油泵的吸力消失,滤网上的杂质 ① A 195-1 diesel engine burned 3 times in a row, a closer inspection found that the machine just started working, the normal oil pressure, working for a period of time, the oil pressure dropped to zero. Stop and then rest for a while, the oil pressure is normal. After working for some time, the oil pressure dropped to zero again. Disassembled found that the oil into the broken leaves and iron filings. After analysis, diesel engine work for some time, the oil impurities will be adsorbed on the suction plate filter, blocking the oil passage, the oil pressure dropped to zero. After the shutdown, the pump suction disappears, the filter impurities
