Interest has increasingly shifted from load-sensing (pressure controlled) systems to flow controlled systems. In this paper an interesting configuration that uses pre-compensated valves with flow sharing properties is studied. The fundamental difference between a traditional load sensing (LS) system and a flow controlled system is that the pump is controlled based on the operator’s total flow demand rather than maintaining a certain margin pressure over the maximum load pressure. One of the main advantages with flow controlled systems is the absence of the feedback of the highest load pressure to the pump. Flow controlled systems also present some challenges, one being how to handle auxiliary functions with unknown flow demands. Auxiliary functions are typically support legs, external power takeouts etc. This paper analyses one kind of flow controlled system and shows one way of dealing with auxiliary functions.
