Description
technical field [0001] The invention belongs to the field of detection equipment, and in particular relates to a detection device for the lift angle of a plunger helical line. Background technique [0002] The plunger coupling is a precision coupling inside the diesel fuel injection pump, usually including two parts: the plunger and the plunger sleeve. When working, the plunger assembly can generate low-pressure fuel into high-pressure fuel, and deliver it to the high-pressure oil pipe through the oil outlet valve assembly, and finally inject the fuel into the combustion chamber. In order to adjust the circulating oil supply of the fuel injection pump, various helixes are arranged on the head of the plunger. According to the requirements of different diesel engine working conditions, the lift angle of the helix of the plunger will also change accordingly. Designers can adjust the rate of change of fuel supply through the change of the lift angle of the plunger helix, so as ...
