Control concept for an advanced load-sensing system
In this contribution, an upgraded version of conventional hydraulic-mechanical load sensing (hmLS) is presented, whose goal is the improvement of both the energetic and dynamic behaviour of the standard system in the main working range. The presented system is controlled depending on the operating point either with the aid of a conventional volume flow controller or an electro-proportional volume flow limiter with reduced pressure difference between the pump pressure and maximum load pressure. This is intended to provide the necessary precision at smaller swivelling angles and lower overall power transmission as well as improved efficiency at a larger swivelling angle using conventional components suitable for mobile use.
