Study of operation of spool hydraulic control unit that transmits reduced pressure signal to control hydraulic distributors, control cylinders, parameters of axial piston pumps and hydraulic motors
The article discusses the test results of three modernized hydraulic control units. In the course of the experiments, the nodes are refined with subsequent refinement tests. As a result, of the research, the following results are obtained: a characteristic of the dependence of the differential pre...

| Summary: | The article discusses the test results of three modernized hydraulic control units. In the course of the
experiments, the nodes are refined with subsequent refinement tests. As a result, of the research, the
following results are obtained: a characteristic of the dependence of the differential pressure on the
flow rate, a dependence of the reduction pressure on the angle of the handle, pressure drops in the
working bends of the control unit, etc. The analysis of the results and comparison with theoretical
calculation shows that there are three main types of adjustment characteristics: parallel theoretical —with
laminar flow, three — zone and quadratic — with turbulent mode. |
