Abstract

A test bench device of a hydraulic valve is formed by a pump station and a test bench. The pump station comprises a first pump device and a second pump device which are installed on an oil tank. The test bench is provided with an oil inlet communicated with the first pump device and two working oil openings communicated with the second pump device. An oil return opening is arranged on the test bench and connected with an overflow valve. The test bench device of the hydraulic valve is less in leakage, simple and compact in structure and low in operating noises, and reduces influence of pump station noises on health of workers.
