Structurally the stand consists of two devices:
- hydraulic device measurement and control module;
The devices are connected by electric and pipe lines. The hydraulic device measurement and control module has frame structure with single sided base containing table, two hydro panels and measurement and control panel.
The measurement and control panel contains basic hydraulic circuit. The circuit is fixed and does not require any assembling before doing laboratory works. Mineral oil is used as operating fluid.
The stand contains: three-phase electric motor, gear-type pump, two pressure hydro valves, filter, one distributor with electromagnetic control and five manually controlled distributors, two-port discharge valve, controlled hydro valve, twin throttle with back valve, hydraulic accumulator, subplates, connection fittings and pipes.
High enough pressures and fluid flow rates visualize the studied processes and facilitate learning the material. Fluid discharge ratio can be widely varied. The information and control system allows to measure pressure, discharge, pump axis rotation velocity, pump power, operating fluid temperature, and time. The stand contains 11 manometers (one electrical), integral velocity meter, electronic tachometer, electronic stop watch, digital kW meter, thermometer with bimetallic gauge.
Two electronic gauges allowing to measure pressure in eight pipe cross sections are used for further increasing measurement accuracy in studying local hydraulic resistances (sudden narrowing or widening).
Some hydraulic devices in the stand are modular. In some of the works the experimental results can be compared with calculations allowing to evaluate calculation errors.
The stand is supplied with a complete set of methodical and technical documents for teaching staff.
