Drivers who drive small concrete mixers all year round should have met such a problem: the oil road is blocked. The solution to this problem is to exhaust air. Today we will talk about how to deal with it.

打扫空气之前，先检查存油。油箱存油缺乏时，应加满后进行排气。由于油箱输油泵这一段油路内柴油压力低于外界大气压力，故这段油路漏气检查应在发动机停熄后进行，防止空气被吸入料系统。小型混凝土搅拌机是一种工作强度大，靠得住性要求高的工程运输车，要担保其的作业情况，平常养护尤为重要。

Check the oil before cleaning the air. When the oil tank is short of oil, it should be filled up and then exhaust. Since the pressure of diesel oil in the oil pipeline from the oil tank to the oil transfer pump is lower than the atmospheric pressure outside, the air leakage inspection of this oil pipeline should be carried out after the engine is stopped to prevent air from being sucked into the fuel system. Small concrete mixer is a kind of engineering transport vehicle with high working intensity and high reliability requirements. In order to ensure its efficient operation, ordinary maintenance is particularly important.

打扫油路空气时，先将手油泵上下往复抽动，并旋松柴油滤清器上的放气螺塞，放气螺塞处溢出的柴油内无气泡中止，再旋紧放气螺塞。接着将手油泵上下往复抽动，并旋松喷油泵油腔上的放气螺塞，滋出的柴油中无泡沫中止，再旋紧螺塞。小型混凝土搅拌机终究旋松高压油管接头，将供油齿条推在大供油方位，运用启动机翻滚曲轴，高压油管接头滥出柴油无泡沫中止，再拧紧管接头。

When cleaning the air in the oil circuit, first move the hand pump up and down, and loosen the vent plug on the diesel filter until there is no bubble in the overflowing diesel at the vent plug, and then tighten the vent plug. Next, the hand oil pump is pumped up and down, and loosens the vent plug on the fuel injection chamber of the fuel injection pump, and the foam is stopped without any foam in the diesel oil, then the screw plug is tightened. Finally, the small concrete mixer will unscrewed the high pressure tubing joint, push the oil supply rack to the large oil supply position, use the starter to roll the crankshaft, overflow the diesel oil pipe joint, overflow the diesel without foam, and then tighten the pipe joint.

小型混凝土搅拌机在进行加油的时候一定要保证油的清洁，要是浑浊的油加入到油箱中就会出现上面这种情况，大家可以到正规的加油站进行加油。

The small concrete mixer must ensure the cleanness of the oil when refueling. If the turbid oil is added into the oil tank, the above situation will appear. You can go to the regular gas station to refuel.
