The development and use of injection pump test rigs is very important. During the development of injection pump test rigs, there are many issues that warrant attention:
Adjust the injection pump test bench injection advance angle. The injection advance angle changes, most of which is caused by the loosening of the screw of the high pressure pump connecting plate. The injection advance angle should be recalibrated. After adjusting the injection advance angle, tighten the high-pressure pump connecting plate bolts to prevent loosening.
Check and adjust the injection pump test stand. According to experience, as long as the use of diesel is carefully managed, the injection pumps and injectors rarely malfunction. If individual cylinder injectors are poorly atomized and do not burn well, they should be calibrated.
