- The paper presets flow characteristics of a hydraulic unit made up of a cylinder and a plunger, which is typical for most of precision pairs, as a function of contamination content in the working fluid. The consideration cover typical cases, including flow of contaminated fluid via an interstice (positive allowance), when the manifold plunger (spool) is in its initial position and the flow rate Qz of the working fluid at the manifold inlet is higher than the flow rate Q via the interstice, the manifold plunger (spool) is in its initial position and the flow rate Qz of the working fluid at the manifold inlet is lower than the flow rate Q via the interstice and when the manifold plunger moves against the manifold cylinder (body). Mathematical relationships, determined for all the above cases, define the following characteristics: volume of contaminants captured upstream the interstice, volume of contaminants captured in the interstice, volume of contaminants that flow out downstream the interstice, flow rate of the working flow downstream the interstice as a function of time, average velocity for the working fluid that flows out of the interstice as well as time interval that is necessary to fill in the interstice. Distribution of contaminants along the interstice length is described as well. The determined relationships served as a basis to find out interconnections between volumes of fluid that flows via an interstice and duration of the flow process.
