Constant Power Variable Electro-hydraulic Control Of The Radial Piston Pump

In this paper the method of simulation is mainly discussed, which aimed at the virtual experiment graphs of electro-hydraulic proportional with sensitive-load valve regulator, computer technology controlling radial piston pump system.this totally different with traditional control method, overcome tradition control structure of way complicated, Control precision low shortcoming, computer technology, electric liquid proportion technical application carry on with pump this to it control constant power.This text fill to control characteristic radial piston pump carry on theory analyse ontroi, Askcontral hydralic control constant power radial variable post that expound the fact fill in pump and traditional radial post fill in pump compare relatively originally. It has a characteristic such as being simple, light, small of structure This text sets out from variable foot-path to the systematic structure of filling in the pump of the control coanstant power. Have discussed tentatively that the whole variable controls principle and basis that each component of link is designed Using simulink aimed at the result of experiments carries out dynamic characteristic of the pump system and drown more ideal result( I )Replace with automatically controlled one ordinary to control characteristic (II )Load sensitive techanologyis is used in the control constant power radial variablepost(III)Rational design controller, proportion flow valve, load sensitive valve make output of pump flow satisfied, thus achieve control characteristic purpose that power replace with automatically controlled one ordinary to control constant power the valve...
