Hydraulic valve test bench (multi-way valve test bench) to test hydraulic directional valve, pressure valve and flow control valve hydraulic control valve three categories of dynamic and static performance, testing agricultural machinery, forklifts, loaders, excavators and marine multi-channel valve dynamic and static performance. Can be equipped with CAT Computer Aided Testing System. Test coverage, test items, test request complies with GB/T8104-1987, GB/T8105-1987, GB/T1987 and other relevant national standards. Hydraulic valve test bench YYFSYT-75KW Main technical parameters: Test Range: directional valves, pressure valves, flow control valves Maximum test pressure: 35MPa Maximum test power: 75KW maximum test flow: 400L/min test accuracy: ISI-B level control: manual or computer product names feature multi-way valve test bench test bench is the 1.8-47T excavators Sunward multi-way valve used in the test was developed. Test parameters through sensors, data acquisition and IPC to achieve static and dynamic data acquisition, processing, printing pressure loss curve, internal leakage curve, safety valves and other pressure characteristic curve, micro valves and safety valves transient response characteristic curve characteristic curve test reports and data management pilot projects `main safety valve set pressure verification ① ② ③ commutation median leakage test ④ ⑤ commutation bit leakage test pressure test performance parameters meet the standard JB / 8729.2-1998" hydraulic multi-channel changer the valve test methods "The hydraulic multi-way directional valve test method pressure; ⑤ Sealing performance GB/T8104, GB/T8105, GB/T8106 total power 110.5KW (75kw + auxiliary motor) KW test pressure 0 ~ 40MPa Flow Range 0.01 ~ 600L / min speed range 0 ~ 1500r/min system temperature water cooling Water cooling control mode structure and composition dynamic system, hydraulic control system, hydraulic oil filtration temperature control system, the workpiece clamping device installation, electrical control systems, data acquisition test systems Scope 1.8- 47T excavator used in multi-way valve
