What is the adjustment method of fuel injection pump?

What is the adjustment method of fuel injection pump? Oil pump nozzle spring manufacturers for you to introduce:

(1) debugging of oil supply time. Remove all the outlet pipe joints, turn the dial so that the outlet of cylinder 1 just starts to bleed oil, align the scale with an integer scale as the 0 scale, turn the dial according to the working sequence, and observe whether the interval Angle of oil supply for each cylinder is 60 degrees (six-cylinder fuel injection pump), and the deviation is within the range of 0.5 degrees.

(2) debugging of starting oil. Start the test bench, set the rotation speed at 200rpm, and the number of oil injection at 200 times. Rotate the control arm to the maximum oil supply position, and press the counting button. The standard injection volume should be 26ml. If the injection volume is abnormal, the positions of the shifting forks of each cylinder on the oil supply rod can be adjusted respectively.

(3) adjustment of oil supply at rated speed. In addition to setting the rotating speed at 900rpm, other operation steps (2) are required for starting the test bench. The standard fuel injection amount should still be 26ml. If the fuel injection amount is abnormal, it can be adjusted uniformly by adjusting the oil amount adjustment screw at the rated speed.

(4) adjustment of idle fuel supply. Start the test bench, set the speed at 250rpm, and set the number of oil injection at 200 times. Press the counting button. The standard fuel injection amount should be 6ml. If the fuel injection amount is abnormal, it can be adjusted uniformly by adjusting the idle oil adjustment screw.
