分配泵转速下降会造成机车功率不足。对此,可以通过调整解决。首先对外部进行调整。将高速限位螺钉松开外旋。如外部调整收效不大,可打开油泵顶盖进行内部调整。先检查油量控制阀开度,若过小可适当加大(但是不可调得太大,开度太大会造成高速断油不彻底,甚至飞车)。通过以上调整效果如果仍不佳,可将调速弹簧取下,换挂钩位置以增加弹簧拉力,必要 Dispense pump speed decline will cause the locomotive power shortage. In this regard, can be adjusted to solve. First adjust the external. Loosen the high speed limit screw. If the external adjustment is not effective, you can open the pump cover for internal adjustment. First check the fuel control valve opening, if too small may be appropriate to increase (but can not be adjusted too much, the opening is too large will cause high-speed oil is not complete, and even speed). Through the above adjustment effect if still not good, you can remove the governor spring, change the hook position to increase the spring tension, it is necessary
