Bench For Study And Training In Hydrostatic And Association Of Serial And Parallel Pump And Data Acquisition (DL HPC-4-CLS)
PL-624012
Workbench for load loss study. It has PVC pipes with different diameters to compare measurements, which are connected by means of flanges to allow their removal, if necessary.
The system is controlled via inverters, Venturi tube and tube for experiments, observations and Reynolds number calculations, which can be easily changed between smooth tubes, simply by replacing the flanges.
To drain unused water, the bank has well-placed hydraulic drains.
Didactic activities
The system allows the following experiments:
- Anti-discharge head research;
- Load loss study on different tubes, connections including smooth tubes, straight tubes of different diameters, hard expansion and contraction, 50 mm radius elbow, 100 mm radius elbow, 90° tube, length 45°, type "t" connection, type "y" connection;
- Study of flow measurement in different measuring instruments including at least: Use of the scale in a volumetric tank, Venturi meter; performance and efficiency of a centrifugal pump;
- Operation of the centrifugal pump;
- Head height measurement;
- Conversion between pressure - height;
- Pressure/flow characteristics of centrifugal pumps;
- Available suction height;
- Filling the pump;
- Sizing and selection of centrifugal pumps;
- Parallel operation characteristics of two similar pumps;
- Series operation characteristics of two similar pumps;
- Parallel operation characteristics of two similar pumps operating at different speeds;
- Series operation characteristics of two similar pumps operating at different speeds.
Goals
Experiences in hydrodynamics and observation of hydraulic phenomena, such as:
- Association of pumps in series and in parallel, such as:
- Series connection of the pumps: R2, R4, R5 and R3 = Open with R4 and R1 = Closed.
- Parallel connection of the pumps: R1, R2, R3 and R4 = Open with R5 = Closed.
- Head loss in pipes and connections.
- Head loss in ascending lines and connections
- Head loss in tubular descent and connections
- Pressure comparison in pipes of different gauges (from ½ to 2 inches)
- Turbulence in rough pipe and smooth pipe
