Computer Controlled Multipump Testing Bench (4 types of pumps)

The Computer Controlled Multipump Testing Bench (4 types of pumps), allows the students to study the operating characteristics of several types of pumps.

ATENG 11828 — Computer Controlled Multipump Testing Bench (4 types of pumps)

(for main items)

• With this unit there are several options and possibilities:
• Main items: 1, 2, 3, 4, 5 and 6.
• Optional items: 7, 8, 9, 10 and 11.
• Let us describe first the main items (1 to 6):
• 1 ATENG 11828. Unit:
  Unit designed to demonstrate the operating characteristics of several types of pumps.
  Anodized aluminum frame and panels made of painted steel.
  The unit includes wheels to facilitate its mobility.
  Main metallic elements made of stainless steel.
  Diagram in the front panel with distribution of the elements
  similar to the real one.
  Fully instrumented self-contained unit.
  The unit is mounted on a structure with a work surface covered
  by a plastic sheet.
• Four pumps (computer controlled):
• Centrifugal Pump: pedestal or of free axis type, made of
  brass.
• Maximum flow: 80 l/min.
• Maximum height: 20 m.w.c. (meters of water column).
• Efficiency: 35%.
• Axial Pump: with propeller, which works in an acrylic casing
• with thin interstices between the propeller and the casing. Unit: ATENG 11828
• Maximum flow: 50 l/min.
• Maximum height: 2 m.w.c. (meters of water column).
• Efficiency: 15%.
• Gear Pump: of positive displacement, with casing of a melted piece and two rotors in form of a
  straight cylindrical gear.
• Maximum flow: 35 l/min.
• Maximum height: 45 m.w.c. (meters of water column).
• Efficiency: 75%.
• Peripheral Pump: also known as regenerator or turbine pump, with a runner of straight blades inside
  an annular casing and an axis of activation on two lubricated ball bearings.
• Maximum flow: 40 l/min.
• Maximum height: 22 m.w.c. (meters of water column).
• Efficiency: 30%.
  Motor for each pump, with independent operating.
  Variation of speed by frequency converter, located in the control interface box, computer controlled.
  There are two pressure tappings in each pump, one at the admission and other at the discharge of the
  pump.
  Calibrated volumetric tank of 0 – 10 l for low flows and of 0 – 45 l for high flows. It includes a level
• sensor (capacitive, length: 300 mm) to determine the water flow and the water level in the volumetric
  tank, an indicating transparent tube and a graduated scale.
  Water storage tank, with capacity of 160 l approx. It includes an indicating transparent tube.
  Two “U” shape weirs.
  Two stilling baffles.
  Valves for centrifugal, peripherical and gear pumps.
  Control valve for axial pump.
  Eight admission pressure sensor and discharge pressure sensor for each pump.
  Reading of torque (Nm) of the pump.
  The software can determine the pump manometric height, the hydraulic and mechanic power and the
  efficiency.

Complete Technical Specifications (for main items)

• The complete unit includes as well:
  Advanced Real-Time SCADA.
  Open Control + Multicontrol + Real-Time Control.
  Specialized Control Software based on LabVIEW.
  National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
  Calibration exercises, which are included, teach the user how to calibrate a sensor and the
  importance of checking the accuracy of the sensors before taking measurements.
  Projector and/or electronic whiteboard compatibility allows the unit to be explained and
  demonstrated to an entire class at one time.
  Capable of doing applied research, real industrial simulation, training courses, etc.
  Remote operation and control by the user, as well as remote support from technical
  support, are always included.
  Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
  Designed and manufactured under several quality standards.
  Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
  calculations, etc. Apart from monitoring user's knowledge and progress reached.
  This unit has been designed for future expansion and integration. A common expansion is
  the Scada-Net (ESN) System which enables multiple students to simultaneously
  operate many units in a network.
