Debugging method for fuel injection pump

(1) Debugging during using. Remove all oil outlet pipe joints, and rotate the dial to make the oil outlet of cylinder 1 start to leak. Then align the scale with any integer scale as the 0 scale. Rotate the dial according to the working order, and observe whether the interval angle of each cylinder's oil supply is 60 degrees (for a six cylinder fuel injection pump), with a deviation within 0.5 degrees. 

(2) Debugging the starting oil quantity. Start the test bench with the speed at 200rpm. Then set fuel injection to 200, and rotate the control arm to the maximum fuel supply position before pressing the counting button. The standard fuel injection volume should be 26ml. If the fuel injection volume is abnormal, the position of each cylinder shift fork on the fuel supply rod should then be adjusted separately. 

(3) Debugging of rated speed fuel supply. Start the test bench with the speed at 900rpm, the other operating steps are the same as (2). The standard fuel injection volume should still be 26ml. If the fuel injection volume is abnormal, it can be adjusted uniformly by adjusting the rated speed fuel volume adjustment screw. 

(4) Debugging of idle fuel supply. Start the test bench with the speed at 250rpm, and set fuel injections to 200 before pressing the counting button. The standard fuel injection volume should be 6ml. If the fuel injection volume is abnormal, it can be adjusted uniformly by adjusting the idle fuel volume adjustment screw.
