Flow Characteristics of Load Limiting Control for Engine hydraulic System

The load limiting control for engine hydraulic systems is a kind of intelligent electro hydraulic control technology that automatically adjusting the variable pump hydraulic system according to load. The principle of load limiting control system was introduced. The conventional load sensing system and LUDV load sensing system were analyzed on the principle and characteristics. The crane hoisting system was taken as the experimental subject. The experimental results are thought to be in accordance with the analysis of the flow characteristics of the traditional load sensing system, thus providing reference for optimizing the control strategy of the load limiting control system.
