Abstract
In control hydraulic components (servo valves, LS regulators, etc.) there is
a need for precise mathematical description of fluid flow through radial
clearances between the control piston and body of component at zero overlap,
small valve opening and small lengths of overlap. Such a mathematical
description would allow for a better dynamic analysis and stability analysis
of hydraulic systems. The existing formulas in the literature do not take
into account the change of the physical properties of the fluid with a change
of thermodynamic state of the fluid to determine the flow rate through radial
clearances in hydraulic components at zero overlap, a small opening, and a
small overlap lengths, which leads to the formation of insufficiently precise
mathematical models. In this paper model description of fluid flow through
radial clearances at zero overlap is developed, taking into account the
changes of physical properties of hydraulic fluid as a function of pressure
and temperature. In addition, the experimental verification of the
mathematical model is performed.
