Particularities in determining the functional parameters of a hydrostatic system

Abstract

Adopting an optimal constructive variant for a hydrostatic installation starts from the calculus of functional and dimensional parameters of composing elements. A right choice has to regard the dependencies between the characteristic values for hydraulic elements. In this paper, a reduced power installation is presented. The installation has classical equipment for distribution, adjustment and control in order to action two hydraulic cylinders. One of these has movement in vertical plane, with variable load. The other assures a horizontal movement of a trolley assembly. Also, are defined specific equations which allow determining a dynamic behaviour of equipment, calculating hydrostatic parameters essentials for installation functioning: working fluid pressures and flows, transferred hydraulic forces and powers etc.
