Abstract

A hydraulic control system of a multifunctional hydraulic testing stand comprises a hydraulic oil source module, a high-flow unloading impact simulation and test module, a hydraulic cylinder impact test and buffer performance test module, a proportional component test module, an oil cylinder test and simulation loading module and a pressure oil source output module. In this way, a module is connected with a test oil cylinder and a loading oil cylinder through a component, and corresponding tests are completed. By the adoption of the hydraulic control system, a clean oil source meeting the requirement of the proportional servo component test can be provided, the output pressure and flow are stable and adjustable, the functions of hydraulic impact testing, high-flow unloading impact testing, buffer performance testing, proportional component testing, proportional servo oil cylinder testing, simulation loading and pressure oil source output are integrated through the system, the integration degree is high, and the application range is wide.

Description

Background technique [0001] With the development of the hydraulic industry, people put forward higher and higher requirements for the reliability of the hydraulic system, among which the performance of hydraulic components and hydraulic shock are important factors affecting the life of the hydraulic system, and the current test for hydraulic shock test and hydraulic component test The functions of the test bench are relatively single, which cannot meet the needs of some special testing, and there is a lack of a multifunctional test bench that can effectively combine the above functions. For example, in the working process of a large-tonnage hydraulic press, the hydraulic shock generated during the unloading of its large flow will have a great impact on the performance of the proportional valve. For performance testing, if the above process needs to be simulated experimentally, it is currently impossible to simultaneously complete the testing of the above process through a sing...
