下面是黄盖淖乡送来的一台铁牛—55拖拉机的(?)号泵,在喷油泵试验台上测得的数据。缸别 1 2 3 4 额定油量(毫升/200次) 20 20 18 20 怠速油量(毫升/200次) 6 6 8 6 由上述数据发现:11号喷油泵第三缸的额定油量较其它三缸低,而怠速油量却比其它三缸高,同时第三缸油管还伴有发热现象。反复测试多次,结果均同。接着又交换了第一缸、第三缸的喷油器和高压油管, Here is the data from the test pump on the fuel injection pump test bed of a tractor (? Cylinder 1 2 3 4 Rated oil volume (ml / 200 times) 20 20 18 20 Idle oil volume (ml / 200 times) 6 6 8 6 It is found from the above data that the rated fuel quantity of the third cylinder of No.11 injection pump is higher than others Three-cylinder low, while the idle oil is higher than the other three-cylinder, while the third cylinder tubing is also accompanied by fever. Repeatedly tested several times, the results are the same. Then exchange the first cylinder, the third cylinder of the injector and high pressure tubing,
