提高喷油泵的调试质量,对提高发动机的动力性及经济性有很大的意义。在调试工作中应注意以下几点: 1.出油阀“自流”的检验出油阀“自流”是喷油泵调试中常遇到的故障。它有着一定的隐蔽性,不容易被发现,“自流”时喷油嘴仍能喷油。建议把它列入调试工艺,当做一个检验项目来进行。喷油泵固定在试验台上,待遮蔽物喷油冲洗油泵油道后、接通高压油管前,将试验台变速手柄放在空档位置(切断主轴动力),开动试验台(使试验台输油泵供油)。扳动刻度盘,使各缸滚轮体总成依
Improve the quality of fuel pump debugging, to improve the engine power and economy have great significance. In the commissioning work should pay attention to the following points: 1. Outlet valve “self-flow ” inspection out of the oil valve “gravity ” is often encountered in the fuel pump debugging failure. It has a certain degree of concealment, not easy to be found, “self-flow ” when the nozzle can still fuel. It is proposed to include it in the commissioning process, as a test project to carry out. The fuel pump is fixed on the test bench, and after the cover oil injection flushing the pump oil passage, put the speed change handle of the test bench on the neutral position (cut off the power of the main shaft) and turn on the test bench (make the test bench oil pump Oil). Pull the dial, so that each cylinder roller body assembly according to
