Embodiment Construction
[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0048] figure 1 Among them, it is mainly composed of a hydraulic test system 32, an electrical control system 33, and a data acquisition and processing system 34. The servo valve 9 to be tested is connected to the hydraulic test system 32; wherein, the main oil circuit in the hydraulic test system 32 passes through the cartridge valve The components are divided into a dynamic oil circuit and a static oil circuit. The hydraulic test system 32 is also equipped with a dynamic oil cylinder 2 for testing the servo valve 9 to be tested; the data acquisition and processing system 34 is connected with the hydraulic test system 32 . The system can complete various detection tests in GB / T 15623-1995 (Test method for electro-hydraulic servo valves), such as zero offset and zero drift test, internal leakage test, no-load flow test, flow load pressure drop test, tra...
