我们在试验台上校正495型柴油机Ⅰ号喷油泵的标定和怠速油量时发现:在标定转速1000转/分、最大油门位置时,调好各缸标定油量6~(+0.2)毫升/100次,在怠速250转/分、最小油门位置时,检查怠速油量发现,二、三、四缸的供油量均为规定值1.5毫升/100次,而一缸的供油量只有很少一点。于是调整了一缸供油拨叉,使一缸怠速油量达到规定值。当升速到标定转速、在最大油门位置检查标定油量时,只见二、三、四 When we calibrated the calibration and idle oil quantity of Type 495 diesel engine No. 1 injection pump on the test bench, we found that when the rated speed is 1000 rpm and the maximum throttle position is adjusted, the calibrated oil quantity of each cylinder is 6 ~ (+0.2) ml / 100 times, at idle speed of 250 r / min, the minimum throttle position, check the idle oil found, two, three, four cylinder fuel supply are the provisions of 1.5 ml / 100 times, and a cylinder of fuel supply is only a little less. So adjust a cylinder fork, so that a cylinder of idle oil to achieve the required value. When the speed up to the calibration speed, check the maximum throttle position calibration fuel, I saw two, three, four
