When the intelligent pump working normally, it will be controlled by computer instruction and be disturbed to its operation by the change of load. It is the key performance that the pump transformed its working status according to the computer instruction and the load. In order to estimate and improve this performance, the overall adjustment process of intelligent pump was surely needed to understand. Aircraft carried hydraulic system was entirety analyzed, and the theory of load impact on intelligent pump was studied. The working process of intelligent pump was simulated by using external force and throttle to imitate the load in the AMESim software. Simulation results show intelligent pump can well adjust to the change of instruction and load. Since the effect of two kinds of adjusting can expediently estimate intelligent pumps performance, it has done the groundwork for advancing its performance.
