油泵工作过程中,由于燃油不清洁,油泵芯套会产生磨损,油泵芯套磨损后,在芯子的斜槽处,特别是小油门位置可以清楚地看出白色的条纹,严重的可以看出粗的拉毛线或斑点。此时油泵不能产生应有的压力,降低泵油性能,严重的使喷油嘴不喷油,若用棉线将套筒上的回油孔堵死,容易发生飞车事故。同时,棉絮很容易被燃油带出,引起出油阀、喷油嘴针阀关闭不严,甚至引起喷油嘴咬死。对已磨损的油泵芯套可采用以下临时办法:在油泵芯子的润滑环槽处,绕上几翻尼龙线,以减少芯套之间的间隙,使压力有所恢复。特别是在大油门位置效果更好。实践证明,这种临时办法可使芯套延长使用100小时。当发现泵
Oil pump work process, due to fuel is not clean, pump core sleeve will wear, pump core sleeve wear, the core chute, especially the small throttle position can clearly see the white stripes, serious can be seen Rough wool or spots. At this time the pump can not produce the proper pressure, reduce the performance of the pump oil, so that the nozzle is not serious fuel injection, if the sleeve to the oil return hole blocked, prone to speed accidents. At the same time, the batt is easily carried out by the fuel, causing the oil valve, nozzle needle valve closed lax, and even caused the nozzle bite. The wear of the pump core sleeve can be used as an interim measure: In the pump core lubrication ring groove, winding several times around the nylon line to reduce the gap between the core sleeve, so that the pressure has been restored. Especially in the throttle position better. Practice has proved that this temporary approach can make the core cover extended use of 100 hours. When the pump is found
