The invention relates to the technical field of superchargers, in particular to a hydraulic high-frequency supercharger for fatigue testing of parts, which comprises an outer sleeve, a linear driving part and a supercharging part which are separately arranged in the outer sleeve, and a connecting column which is arranged at one end of the outer sleeve and is communicated with the supercharging part, a leakage detecting part used for detecting the total leakage amount of the linear driving part and the pressurizing part is arranged between the linear driving part and the pressurizing part, a cooling part used for cooling is arranged on the outer side of the pressurizing part, a split type structure is adopted, by controlling the segmentation length of high-precision parts, the percent of pass of the parts can be effectively guaranteed, the machining difficulty is reduced, and meanwhile the machining efficiency is improved. Meanwhile, when a certain part is damaged, targeted replacement can be conducted, interference caused by other structures is avoided, the heat dissipation effect is good, abrasion is small, high-pressure and high-frequency working conditions can be borne, meanwhile, the total leakage amount of a system can be automatically detected, and the abrasion degree of the supercharger can be evaluated.
Description
technical field [0001] The invention relates to the technical field of superchargers, in particular to a hydraulic high-frequency supercharger used for fatigue testing of parts. Background technique [0002] A complete vehicle needs to be composed of a large number of structural parts. These structures are either welded or bolted together to form the complete vehicle structure. They carry random loads from the ground or random loads from the internal power system. In theory, all These structures will fatigue failure after a certain period of time. Before the product is finalized, a series of analysis and tests must be carried out by the fatigue life tester to ensure that the component or system component can meet a certain life requirement. Of course, the life requirement of the system level is much lower than that of the component. Class life requirements. The fatigue life testing machine needs to use a hydraulic high-frequency booster, which pressurizes the low-pressure ...
