What is it about?
There is very limited literature describing the different flow of hydraulic pumps working parallel and simultaneously in one hydraulic power pack unit. Several investigators have presented analysed hydraulic central power pack with multipump structure as a single-pump with capacity equal simple multiplication of the some smaller standard pump. Such simplified models of the power packs move to the analysis of the single big hydraulic pump, not as group independent smaller pumps. It lead to mistake.

Why is it important?
Our finding show that in the practice different adjustments of regulators move to different flows of individual pumps during simultaneously work in one power pack unit. The non-proportional flow problem creating in such power pack structure and having the influence on total output flow and power
Perspectives
Writing this article was a great pleasure for presentation my personal activity and research during my work in shipyard at one of the biggest hydraulic systems.
