装配和更换气门座圈是一项重要的修理工序。如果气门座圈材质选择不合理,公差配合及装配工艺不当,以及制造误差,都直接影响发动机的正常工作。冷压锈蚀法装配气门座圈,效果不错。在加工气门座圈时,要保证气门座圈与气门座孔配合紧度在0.15～0.17毫米范围内,锥度在0.005～0.015毫米范围内,圆度在0.010～0.015的范围内。安装时将座圈涂一层溴水后,对正气门座孔,并用力缓慢压入(不要用锤击入)。冷压锈蚀,改变了过去加热升温后再装配的方法。既坚固耐用,又
Assembly and replacement of the valve seat is an important repair process. If the valve seat material selection is not reasonable, tolerances and improper assembly process, and manufacturing errors, all have a direct impact on the normal operation of the engine. Cold pressure assembly valve seat rust, the effect is good. In the process of valve seat, to ensure that the valve seat and valve seat hole tightness in the range of 0.15 ~ 0.17 mm, taper in the range of 0.005 ~ 0.015 mm, roundness in the range of 0.010 ~ 0.015. After installing the seat ring with bromine water, align the valve seat hole and press it in slowly (do not use hammer). Cold pressure corrosion, changing the heating and heating before the reassembly method. Both durable and yet
