Water hydraulic cylinder leakage detection test bed for simulating dynamic load impact

The invention belongs to the technical field of water hydraulic pressure, and particularly relates to a water hydraulic cylinder leakage detection test bed for simulating dynamic load impact, which comprises a water hydraulic cylinder, the water hydraulic cylinder comprises a first water cavity and a second water cavity, and a leakage detection device is arranged in the first water cavity; the hydraulic water loop is fixedly communicated with the second water cavity; the hydraulic cylinder comprises a first oil cavity and a second oil cavity, and the piston end of the hydraulic cylinder is fixedly connected with the piston end of the water hydraulic cylinder; and the hydraulic oil loop is fixedly communicated with the first oil cavity and the second oil cavity. The dynamic load impact simulated by the hydraulic system is more suitable for the actual working condition, whether leakage occurs under the dynamic load impact or not is detected by detecting the change of the capacitance, the accuracy is high, the o
