Sažetak

The non-proportional flow problem of hydraulic pumps with constant pressure regulator in case of simultaneous work in Power Pack Unit with advanced multipump structure in open supply system is presented in the paper. Main parts of hydraulic power pack unit with multipump structure, mounted on board of modern product and chemical tankers and pump constant pressure regulator DP type, are described. Coefficients of non-proportional pump flow phenomena are defined. Analysis of non-proportional flow problem referring to four hydraulic axial piston pumps simultaneously working with pressure constant regulator in Power Pack Unit in open system is presented. The idea of non-proportional pump flow phenomenon reduction is discussed. Conclusions are presented.
