辽宁518—22/60、东风—28/30拖拉机采用大连产喷油泵,由于操作不当,有时因飞球座总成卡入传动盘三角区,使供油拉杆达不到最大油量位置,或因柱塞偶件磨损严重,使油量、尤其是起动油量大减—导至不易起动或不能起动。有的驾驶员打开检视窗盖,撬柱塞调节叉,使供油拉杆向增加油量方向移动。可是,调速器油门拉板变形了,原来装配调整状态遭到破坏。结果各工况油量增加,各工况转速升高,当转速升高到一定程度时,对转速便失去控制,以致引起“飞车”。轻者造成机械加剧磨损,重者会造成机械事故。
Liaoning 518-22 / 60, DF-28/30 tractor Dalian production injection pump, due to improper operation, sometimes fly ball seat assembly snap into the drive plate triangle, the fuel rod can not reach the maximum fuel position, or Due to the serious wear and tear of the plunger, so that the amount of oil, especially the starting oil greatly reduced - leading to not easy to start or can not start. Some drivers open the window cover, pry plunger adjustment fork, the fuel rod to increase the amount of oil to move. However, governor throttle pull plate deformation, the original state of assembly has been damaged. As a result, the amount of oil in each working condition increased and the rotational speed of each working condition increased. When the rotational speed increased to a certain extent, the rotational speed was out of control and the “flying car” was caused. Light caused by mechanical aggravate wear and tear, severe cases can cause mechanical accidents.
