Analysis of energy losses in a hydraulic load sensing proportional valve
Аннотация
The paper presents modeling and simulation of a hydraulic proportional valve PVG 32 by Danfoss widely used in agricultural machinery. A suitable mathematical model is created in LMS Amesim and SolidWorks Flow simulation software programs with the analysis of its energy performance. Their outcomes are validated with the experimental results to correctly describe the real valve characteristics. Since the spool valves are designed with overrunning loads in mind, considerable throttling losses are observed in the discharge line when the machine is operating with a resistive load.Therefore; this paper suggests the possibility of implementing energy saving techniques in the valve by using independent metering and gives simulation model for further use.
