New Hydraulic High-Pressure Impulse Generator for Long-Duration Impulse Tests

Water hammer wave is widely applied to test hydraulic components in various areas. A new high-pressure impulse generator presented this paper order provide the standard water for long-term usage. combination of a sleeve and rotary spool was used build generator, booster piston amplify output pressure. Mathematical models were established using commercial software, prototype rig built based on simulation results. The experimental results both single repeated periods show feasibility design indicate that can be long-time tests.
