Download this article in .PDF format. When a ,hydraulic, pump operates, it performs two functions. First, its mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line to the pump. Second, its mechanical action delivers this liquid to the pump outlet and forces it into the ,hydraulic system,.

Into the ,hydraulic system, (node 1) the negative flow Q = –200 l/min (according to the accepted direction of flows) moves. The ,hydraulic, circuit contains 9 elements and 14 nodes and is described by ,system, of differential-algebraic equations of the 31-st order. Main parameters of the ,hydraulic system,: ,hydraulic, cylinder: piston diameter 100 mm,

Hydraulic, systems can be open centre ,system, or closed centre ,system,. An open centre ,system, is one having fluid flow, but no pressure in the ,system, when the actuating mechanisms are idle. The pump circulates the fluid from the reservoir, through the selector valves, and back to the reservoir.
