Structurally, the stand consists of two subsystems: hydraulic and electrical. The hydraulic subsystem is made with a closed circulation of the working fluid, which is used as water. When installing the stand, it is not required to connect it to water supply and sewerage systems.
On the front panel of the stand there are digital displays of the measuring system, signal indicators, pump controls, automatic switches for protecting electric motors of pumps, and a schematic hydraulic circuit is shown.
The following equipment is installed on the stand:
- two pumping units, each includes a cantilever-type rotary pump and a 3-phase asynchronous electric motor;
- one hydraulic tank;
- pipelines with shut-off and control valves;
- power supply system;
- data measurement system.
The data measurement system allows to rate pressure (on pumps’ inlets and outlets), instant fluid flow, power on the electric motor inputs. The results of measurements are digitally indicated on an electronic screen.
In order to provide high performance of microprocessor sensors and achieve the required precision the stand features specially designed anti-jamming system.
The stand is supplied with a set of methodical and technical documentation for teaching staff.
