Description
technical field [0001] The invention belongs to the field of machinery, and in particular relates to a solenoid valve fatigue tester for an electric control pump. Background technique [0002] The VE pump supplies oil to the single plunger, and through the distributor, the fuel is supplied to each combustion chamber for combustion. The functions of the VE pump mainly include oil supply distribution, start-up and speed regulation, advance angle adjustment, stop and so on. The electronically controlled VE pump mainly electronically controls the fuel injection volume, fuel injection advance angle, and shuts down when the fuel is cut off. [0003] Solenoid valves for electronically controlled pumps are important electrical components. The working performance and parameters of this accessory play a very important role in the development and application of electronically controlled pumps. Therefore, it is necessary to verify the performance of solenoid valves under different volt...
