AUTOMATED TRAINING LABORATORY COMPLEX FOR DETECTION OF HYDRAULIC MACHINES CHARACTERISITCS AND MODES Russian patent published in 2010 - IPC G09B23/12 

FIELD: measurement equipment.

SUBSTANCE: invention is related to equipment for demonstration-practical detection of centrifugal pump operation features, characteristics of joint operation of two pumps that are connected parallel to circuit, etc, by students. Complex comprises tables 1, 4. Table 1 consists of horizontal and vertical surfaces 2, 3. On surface 2 there is water-pressure manifold arranged, which starts and ends in makeup tank 5 with drain valve 6. Above tank 2 there are two pump stations 7, 8 fixed. Horizontal section of manifold includes two electronic converters of pressure 18, 21 to register main readings and for control measurement, valve 19 for pressure control, water counter 20. In the end horizontal section branches into two pipes with valves 23, 24 to control water supply and safety tap 27, from where section starts, having pipe 28 of larger diametre compared to the main manifold. On vertical surface 3 of table 1 there is control system and panel 36 for registration and processing of readings in electronic computing machine. On horizontal surface 37 of the second table 4 there is unit 38 of computer with analog-digital converter.

EFFECT: improved accuracy and quality of measurements and automation of all necessary parametres registration.
