Description
technical field [0001] The invention belongs to the field of experimental equipment, in particular to performance testing equipment for hydraulic valves. Background technique [0002] Hydraulic transmission has many advantages such as high power density, compact structure, flexible layout and high control precision, and is widely used in various electromechanical systems. The hydraulic valve is an important control component of the hydraulic system, and its performance directly affects the performance of the hydraulic system, and is an indispensable component of the hydraulic system. Therefore, testing the performance of hydraulic valves is an indispensable link in the design and production of hydraulic valves. The performance testing of hydraulic valves can guide the design of hydraulic valves and control the production quality of hydraulic valves. The general hydraulic valve performance test system has single performance and small load adjustment range. Therefore, there ...
