The invention discloses a PWM electromagnetic valve durability testing device which comprises a bracket, a booster oil pump, a pressure sensor, a temperature sensor, an oil tank, a closing valve and an oil temperature regulating component. The surface of the bracket is provided with a plurality of electromagnetic valve seats which are uniformly distributed. The side wall of the electromagnetic valve set is provided with a slot. The electromagnetic valve seat is internally provided with an oil path. The electromagnetic valve seat is provided with an electromagnetic valve through the slot. The side wall of the electromagnetic valve outside the electromagnetic valve seat is provided with a separator plate. The side wall of the separator plate is provided with a circular hole. The electromagnetic valve is arranged in the through hole. The upper end of one side, which is next to the electromagnetic valve seat, of the baffle plate is provided with a fixed rod which is fixedly arranged. The side wall of the electromagnetic valve seat is provided with a circular trough which matches the fixed rod. According to the PWM electromagnetic valve durability testing device, in performing durability testing on the electromagnetic valve, mounting and detachment of the electromagnetic valve and the electromagnetic valve seat are facilitated, and PWM electromagnetic valve testing efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of solenoid valve testing devices, in particular to a PWM solenoid valve durability testing device. Background technique [0002] The PWM solenoid valve is a widely used mechanical-electrical-hydraulic integrated product, and the working life of the PWM solenoid valve is a crucial parameter. In the research and development of PWM solenoid valves, the test device for the durability test of PWM solenoid valves is a very critical step. The endurance test needs to simulate the actual working conditions of the solenoid valve under test. The testing device in the prior art may cause wrong judgment on the working life of the tested solenoid valve. [0003] After searching, the Chinese patent authorization number is the patent of CN204166056U, which discloses a proportional solenoid valve durability test device, including a test device bracket and a solenoid valve seat. A plurality of solenoid valve seats are arra...
