柴油机上为保证进油清洁,在低压油路中设置了多道滤芯与滤网,但在柴油机长期工作中,如果油料管理不严,油中混有杂物,容易引起油路堵塞,使油路中压力迅速下降,空气便通过油箱从放气回油管道倒流入内,致使柴油机“熄火”。每次清除油污后,还需排除油路中的空气。据测定,每次排放油路中的空气浪费柴油50～100毫升左右,清除污物浪费的柴油更多,由于排气次数的增加,油管接头螺丝拧动频繁,从而促使了油路漏油或进气。为避免经常去排除油路中的空气,并防止空气从放气回油管倒流,我们改进了原油路。改进后的新油路(见图)把滤清器上的放气螺孔堵死,取消放气回油管,预热塞的油管可接
Diesel engine to ensure oil into the clean, low-pressure oil in the road set up a multi-channel filter and filter, but in the long-term diesel engine, if the fuel management is not rigorous, oil mixed with debris, easily lead to clogging the oil, the oil Rapid pressure drop in the road, the air from the deflated back to the oil tank back into the pipeline, resulting in diesel “flame out.” After each removal of oil, but also need to rule out the oil in the air. It is determined that every discharge of air in the air waste of diesel about 50 to 100 ml, to remove waste dirt more diesel, due to the increase in the number of exhaust pipe fittings screwed frequently, which prompted the oil spill or Intake. To avoid frequent removal of air from the oil circuit and to prevent backflow of air from the bleed oil return pipe, we have improved the crude oil circuit. The improved new oil circuit (see photo) blocked the bleeder screw hole on the filter, cancel the deflation return pipe, and the glow pipe can be connected
