喷油泵上的高压油管,由于安装不正,硬别着或油管过长,工作中受发动机振动的影响,时间久了油管凸头处很容易别断或振断。若在田间作业时产生断管,得不到及时修理,就要耽误生产。针对这种情况,我们自制了下面图示的一种鼓形圈(内径和外径可根据高压油管的直径加大或缩小),随身携带几个。遇到油管断裂时,取下油管将原凸头用钳子央夹断,修圆管口后将鼓形圈套上,用钳子卡紧油管。用鎯头轻击油管口边缘,使其下翻裹住鼓形圈,即可装机使用。
High-pressure fuel injection tubing, due to improper installation, hard to do or tubing is too long, the work by the impact of engine vibration, oil pipe head for a long time is very easy to break or vibration. If broken pipes are produced during field operations and can not be repaired promptly, production will be delayed. In this case, we made a self-made drum ring as shown below (the inner diameter and the outer diameter can be increased or decreased according to the diameter of the high-pressure tubing) and carry a few with you. In the event of a tubing break, remove the tubing to remove the prongs from the prongs and pinch the prongs, round the prongs and wrap the drums with tubing and tighten the tubing with pliers. Tap the edge of the nozzle with a tip, so that the next turn wrapped around the drum ring can be installed to use.
