一是水箱中为什么冒气泡 柴油机水箱中冒气泡,一般是气缸中的高压气体窜入冷却水道造成的。其原因有:(1)未按规定扭矩拧紧缸盖螺母,高压燃气窜入水道;(2)气缸垫使用时间过长,密封性差,造成漏气;(3)气缸垫被冲坏或烧损,造成窜气;(4)缸盖平面加工不平或变形,造成漏气;(5)装配不当,造成缸套台肩处断裂而窜气;(6)缸盖台肩高度过大,造成缸套装入机体后,凸出机体平面高度不足,甚至下降,燃气就会从台肩处窜入水道。
First, why the bubble in the water tank bubbling bubbles in the water tank, usually high-pressure gas cylinder into the cooling water channel caused. The reasons are: (1) failure to tighten the cylinder head nut torque, high-pressure gas fleeing into the waterway; (2) the cylinder pad is too long, poor sealing, resulting in leakage; (3) cylinder pad is washed or burned , Resulting in channeling gas; (4) cylinder head flat surface processing or deformation, resulting in leakage; (5) improper assembly, resulting in cylinder liner shoulder rupture and channeling gas; (6) cylinder head shoulder height is too large, Set into the body, protruding body plane height is not enough, or even decline, the gas will be fleeing into the channel from the shoulder.
