Problem of Non Proportional Flow of Hydraulic Pumps Working with Constant Pressure Regulators in Big Power Multipump Power Pack Unit in Open System

2019 Tehnički Vjesnik  
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 nonproportional flow
