我们采用一种磨具,研磨油咀头体内密封锥面近处,大大提高了原配修复油咀头的比率。从1970到现在,用此磨具修好了大量喷油器。一、用一种磨具研修油咀头的分析在针阀和针阀体互研后由于针阀和阀体密封锥面在长期工作中的冲击磨损,破坏了原来的配合。另一方面在修复过程中,由于用研磨剂反复互研密封锥面,结果在油咀头体的密封锥面下端产生了一圈凸台(如图
We use a grinding tool, grinding oil tip close to the body sealing cones, greatly improving the original repair Fu Tsu Tsui ratio. From 1970 till now, a large number of injectors were repaired with this grinding tool. First, with a kind of grinding wheel repair oil Tsui analysis in the needle valve and needle body after the research as a result of needle and valve seal cone in the long-term work of the impact of wear and tear, undermining the original with. On the other hand in the repair process, due to repeated research with the abrasive seal cone, the results in the oil tip of the cone seal the lower end of a circle of boss (Figure
