Abstract:Aiming at the problems of the few functions, poor reliability, and low test accuracy and efficiency of the existing hydraulic multi-way valve test platform, a multi-function hydraulic multi way valve test platform based on Programmable Logic Controller (PLC) was designed. The test platform was composed of hydraulic test system, work station, PLC acquisition control system, touch screen and host computer, and etc. The practical applications show that the test platform can meet the test requirements of the hydraulic control and electro-hydraulic proportional control of multi-way valve, and have high test accuracy and efficiency, as well as high reliability and friendly user interface. It will provide the experimental support for the test, design and maintenance of the product leaving factory.
