Description

Floor-standing version of the stand. The stand contains: a frame structure with an instrument panel, a process tank, two centrifugal pumps (pumping unit: plastic and stainless steel), a system of pipelines and taps, a tank for working fluid (water), a frequency regulator for controlling the shaft speed of one of the pumps; 2 flow meters for measuring flow with an electronic output to a digital display, absolute pressure sensors with a digital output for measuring pressure values ​​at the outlets and suction of pumps, an ADC board, a laptop. Data collection is automated.
The maximum pump head is not less than 20 m, the maximum flow rate is not less than 60 l/min, the motor power of the pump unit is 0.63 kW. System for measuring power consumption by an electric motor.
Overall dimensions of the stand: length x width x height 1400x650x1700
Power consumption, no more, kW 2
Electrical power: single-phase 220 V, 5o Hz
Water tank capacity 90 l
Stand weight without water, no more than 110 kg
Work autonomously without connection to water supply and sewerage. For refueling, taps are provided for connecting the water supply and for draining water into the sewer.
List of laboratory works:
1. Study of the operating and cavitation characteristics of the pump at various rotation speeds.
2. Study of the characteristics of two parallel-connected pumps.
3. Study of the characteristics of series-connected pumps.
4. Study of pressure losses on a system of pipelines and taps for various types of connections
5. Coordination of pump and network characteristics
