The training laboratory stand is designed to carry out laboratory experiments on “Hydraulic equipment” course in secondary specialized and higher educational institutions.
On the frame supporting structure of the stand, made in the form of a one-sided basis with a table, there are two panels: hydraulic and electric. The electrical panel of the stand shows a hydraulic circuit diagram. At the bottom of the stand is a hydroelectric station and a bedside table with drawers for storing pipelines, hydraulic devices with mounting plates. The hydraulic panel of the bench contains a type-setting field on which the necessary devices with mounting plates are installed in the laboratory work. Devices are connected using flexible pipes and quick couplings.
Before conducting a laboratory experiment, it is necessary to assemble a system diagram of the required configuration. It allows to increase the number of experiments performed, as well as change, if necessary, the functionality of the stand in the future.
The basic equipment of the stand includes:
- three-phase electric motor;
- gear pump;
- pressure filter;
- two pressure hydraulic valves (direct and indirect action);
- pressure reducing valve (indirect action);
- manual control valve;
- two-line flow controller;
- adjustable throttle.
When selecting hydraulic devices, the matching of their characteristics in pressure and flow rate is ensured, which allows them to conduct experimental studies in various modes, including nominal ones.
The information-measuring system of the stand allows you to measure:
- pressure (four manometers),
- flow rate (two flowmeters – volumetric and high-speed types),
- fluid temperature
- time (electronic stopwatch).
The manufacturer, at the request of the customer, is ready to increase the list of equipment included in the delivery and increase the number of laboratory work performed at the stand.
A set of methodological and technical documentation intended for the teaching staff is supplied with the stand.
