31.长期不清洗机油滤清器滤芯会出现什么故障? 机油滤清器的基本功能是滤清润滑油中的杂质,将清洁干净的润滑油送入主油道。润滑油进入滤清器外腔后,在由机油泵产生的油压的作用下,穿过滤芯进入滤清器内腔,这时润滑油中的杂质颗粒被滤芯滤除,附在滤芯外表面。在柴油机运转过程中,附着在滤芯外表面的杂质越来越多,机油穿过滤芯的阻力增加,进入机油滤清器内腔和主油道的润滑油相应减少,润滑系统机油压力也明显降低。通常把这种现象称作滤芯堵塞。
31. Long-term failure to clean the filter oil filter what will happen? The basic function of the oil filter is to filter the impurities in the lubricant, the clean oil into the main oil. Lubricating oil into the filter after the cavity, the oil pump generated by the oil pressure, through the filter into the filter cavity, then the impurities in the oil filter is filtered, attached to the outer surface of the filter . During the operation of the diesel engine, more and more impurities are attached to the outer surface of the filter element, the resistance of the oil passing through the filter element increases, the amount of lubricating oil entering the inner cavity of the oil filter and the main gallery decreases correspondingly, and the lubricating oil pressure of the lubricating system also decreases significantly . This phenomenon is often called filter plugging.
