柴油机曲轴箱负压值的高低对柴油机的性能有较大的影响,曲轴箱负压值低不但会使机油消耗量增加(窜、烧机油),引起各静、动接合面处渗漏,而且在活塞与缸套密封不好时,还会使柴油机机温升高等。S1100、S1100T型柴油机原采用通气管式的曲轴箱降压,后改用呼吸器式负压阀装置代替。下面谈谈影响S1100柴油机曲轴箱负压值的有关因素: 1.空气滤清器的型号不同装通气管的S1100柴油机如配装的是三级空气滤清器,在额定工况下新机曲轴箱负压值一般在980～1076帕。而更换一只A型空气滤清器,其曲轴箱负压值一般
The negative pressure value of the diesel engine crankcase has a greater impact on the performance of the diesel engine. The negative crankcase pressure will not only increase the oil consumption (channeling, burning oil), causing leakage at the static and dynamic joints, but also In the piston and cylinder seal is not good, but also make diesel engine temperature rise. S1100, S1100T-type diesel engine used snorkel crankcase decompression, later replaced with respirator negative pressure valve device instead. Here to talk about the impact of S1100 diesel engine crankcase negative pressure value of the relevant factors: 1. The type of air filter with different snorkel installed S1100 diesel engine is equipped with a three-stage air filter, under the rated conditions of the new machine crankshaft Negative pressure value of the box is generally 980 ~ 1076 Pa. The replacement of a A-type air filter, the crankcase negative pressure value in general
