Description

technical field [0001] The invention relates to the technical field of hydraulic testing, in particular to a hydraulic testing system of an actuator and a hydraulic testing device thereof. Background technique [0002] In order to test the watertightness of equipment and related parts and the water pressure performance of the body, it is necessary to use hydraulic testing equipment for testing; hydraulic testing is an indispensable part of industrial production. [0003] In real life, the water pressure test equipment will be unstable due to the unstable output pressure of the water pump during use, which may easily cause damage to the workpiece under test and unstable pressure, which cannot meet the test requirements, and there is a great potential safety hazard; for this reason, how to solve the pressure Stability has become an urgent problem to be solved. [0004] A water pressure automatic monitoring system disclosed in a Chinese patent (application number: 202110693370...
