Research on Controllable High Pressure and Large Flow Test Equipment

To meet requierment of dynamic characteristic test of high pressure and large flow relief valve of hydraulic support,controllable high pressure and large flow test equipment is developed.The techniques such as piston accumulator,closed-loop proportional flow control and multi-accumulators relay are studied.The AMEsim software is used to model and simulate.The results of simulation show that device can meet requirements of test standard.
