全自动搅拌车排气管滴水冒蓝烟是怎么回事?

所属分类:行业新闻 发布时间:2020-12-22 来源:http://www.shanqijituan.com 浏览量:18

全自动搅拌车的排气可能会冒蓝烟,并且排气管可能会垂下。
The exhaust of the fully automatic mixer may emit blue smoke and the exhaust pipe may hang down.
当机油严重地插入燃烧室并蒸发时,废气变成蓝烟。蓝烟实际上是油蒸气的冷凝。柴油发动机在冷启动或低负载期间可能会发出蓝烟,但在汽车温暖或负载增加时会消失。这是因为如果燃烧不完全,通常会燃烧掉油蒸气并散发出黑烟。
When the oil is heavily inserted into the combustion chamber and evaporates, the exhaust gas turns into blue smoke. Blue smoke is actually condensation of oil vapor. Diesel engines may emit blue smoke during cold start or low load, but will disappear when the car is warm or when the load increases. This is because if the combustion is not complete, oil vapor will be burned and black smoke will be emitted.
烟灰蓝烟的结果是燃料消耗的迅速增加,导致大量的碳沉积物和其他燃烧产物,降低了喷油器和活塞环的性能,以及活塞和气缸套等磨损环的性能。加速。应尽可能避免。
The result of soot blue smoke is a rapid increase in fuel consumption, resulting in large amounts of carbon deposits and other combustion products, which reduces the performance of fuel injectors and piston rings, as well as the performance of wear rings such as pistons and cylinder liners. Speed up. It should be avoided as much as possible.

1.倒角的活塞环或扭曲环移位,并且油泵(混凝土搅拌机)进入燃烧室。
1. The chamfered piston ring or twisted ring is displaced and the oil pump (concrete mixer) enters the combustion chamber.
2.柴油机长时间低负荷运转(负荷小于30-50%),气缸压力低。
2. The diesel engine runs at low load for a long time (the load is less than 30-50%), and the cylinder pressure is low.
3.闯入操作不足。测试表明,新的或检修过的柴油发动机通常需要运转30-40小时才能达到良好的技术条件。直接正常负载运行而没有磨合是蓝烟的更常见原因。
3. Insufficient intrusion operation. Tests show that new or overhauled diesel engines usually need to run for 30-40 hours to reach good technical conditions. Direct normal load operation without running in is the most common reason for blue smoke.
4.与活塞环和气缸套内表面的光滑度,椭圆度,锥度相匹配的间隙不符合要求,或者由于连杆弯曲,活塞偏心,主轴孔和气缸套不垂直,吹蓝色的烟雾。
4. The clearance matching with the smoothness, Ovality and taper of the inner surface of the piston ring and cylinder liner does not meet the requirements, or because the connecting rod is bent, the piston is eccentric, the main shaft hole is not vertical to the cylinder liner, and blue smoke is blown.
5.油底壳太多,油压太高,粘度太低,活塞环磨损,失去弹性或活塞与缸套之间的间隙太大,油底壳类型空气滤清器油盘中的油太多。
5. There are too many oil pans, too high oil pressure, too low viscosity, worn piston rings, loss of elasticity, or the gap between piston and cylinder liner is too large, and there is too much oil in the oil pan of air filter of oil pan type.
