要想保证气缸垫的密封性能,避免冲缸垫的现象发生,应陔在修理中做到以下几点: (1)对缸盖要作检查,如有变形,可采用校正或磨削、刮研的方法使气缸盖表面光滑平整。对缸体上表面如有凹陷变形,也需采用同样的方法来达到表面光滑平整。 (2)气缸盖螺栓拧紧时,应按从中间往两头的顺序逐步进行,各个螺栓的扭矩应符合规定要求。对铸铁气缸盖,在试车走热后应对其气缸盖螺栓作再一次紧固。
In order to ensure the sealing performance of the cylinder head gasket, to avoid the phenomenon of red cylinder pad, should be done in the repair of the following points: (1) to check the cylinder head, if deformed, can be used to correct or grinding, scraping Research methods make the cylinder head surface smooth. If the surface of the cylinder concave deformation, also need to use the same method to achieve a smooth surface. (2) When tightening the cylinder head bolts, it should be carried out step by step from the middle to the two ends. The torque of each bolt should meet the requirements. On the cast iron cylinder head, after the test drive to heat the cylinder head bolts for fastening again.
