造成柴油机拉缸的原因主要有10个方面:(1)冷却水不足、气缸套润滑不良冷却水大量消耗、泄漏、放水螺塞松脱,冷却水流尽,造成机温过高,破坏了油膜,使活塞与缸套呈半干摩擦状态,进而造成缸套与活塞拉伤;气缸套润滑油量不足,机油黏度过高或过低,与活塞配合间隙过小等,也会使气缸套表面因局部润滑不良、摩擦加剧而使温 There are mainly 10 reasons that cause the cylinder of cylinder of diesel engine: (1) Insufficient cooling water, poor lubrication of cylinder liner Large consumption of cooling water, leakage, looseness of drain plug and cooling water flow, resulting in excessive engine temperature and destruction of oil film. Piston and cylinder liner is semi-dry friction state, resulting in cylinder liner and piston strain; lack of cylinder liner oil, oil viscosity is too high or too low, and the piston with the gap is too small, etc., will make the cylinder liner surface due to local Poor lubrication, increased friction and temperature
