Embodiment 1
[0049] like Figure 1-3As shown, the present invention discloses a pressure limiting valve fatigue test device, including: a housing 1, an actuator plug 3, a push-pull electromagnet 4 and a host computer, the housing 1 includes an oil storage tank 11 and a pressurized cylinder 12, the The top of the pressurizing cylinder 12 communicates with the bottom of the oil storage tank 11, and both the oil storage tank 11 and the pressurizing cylinder 12 store organic oil;
[0050] The oil inlet end of the pressure limiting valve 2 penetrates into the upper end of the pressurized cylinder 12 through the oil storage tank 11, and the pressure limiting valve 2 is provided with an oil hole 21 communicating with the oil storage tank 11, and the oil is immersed in the The oil hole 21, the oil storage tank 11 is provided with a flow sensor 15 for detecting the oil flow rate at the oil hole 21;
[0051] The actuating plug 3 is located in the pressurizing cylinder 12, the actuating plug 3 is in...
Embodiment 2
[0066] The present invention also discloses a fatigue test method for a pressure limiting valve using the pressure limiting valve fatigue test device described in Embodiment 1, such as Figure 4 As shown, the method includes the following steps:
[0067] S1. Set the test parameters on the host computer; such as the number of executions, the temperature range of the oil required for the experiment, the maximum pressure that the executive plug 3 applies to the oil, etc.;
[0068] S2. Detect the temperature of the engine oil, if the temperature of the engine oil is lower than the minimum set value t, then execute step S3, otherwise execute step S4;
[0069] S3, start the heater 13 to heat the engine oil, and execute step S2;
[0070] S4. Detect the temperature of the engine oil, if the temperature of the engine oil is higher than or equal to the maximum set value T, then execute step S5, otherwise execute step S6;
[0071] S5, the heater 13 stops heating;
[0072] S6, the push...
