PBAC コンピューター制御軸流ポンプベンチ





The Computer Controlled Axial Pump Bench, "PBAC", is designed to study this type of pumps. It is a bench-top unit that consists of a computer controlled axial pump, a water tank and circulation pipes with a flow regulation valve. Besides, it includes the control elements required for the pump’s testing: two pressure sensors and one flow sensor.

A frequency inverter for the pump, computer controlled, provides the possibility of regulation and measuring the pump motor speed, as well as the measurement of the torque transferred.

The pump is installed in a system of pipes. As the circuit is closed, it prevents a continuous waste of water when working with it.

The Computer Controlled Axial Pump Bench, "PBAC", unit has instrumentation and sensors to allow the measurement, from the computer, of the most typical parameters of the pumps:

  • Motor turn speed.
  • Total impelled flow.
  • The admission and discharge pressure.
  • Torque.
  • Calculated values:
  • Total height.
  • Hydraulic and mechanic power.
  • Efficiency.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.



  1. Determination of the Q vs. r.p.m. Curve for an axial pump.
  2. Determination of the H vs. Q curve for different r.p.m. Of an axial pump.
  3. Determination of the mechanical power vs flow for different r.p.m. of an axial pump.
  4. Determination of the h vs flow curve for different r.p.m. of an axial pump.
  5. Determination of an axial pump’s map.
  6. Sensors calibration.


Additional practical possibilities to be done by the end customer:

  1. Obtaining the H(n) and N(n) curves.
  2. Study of the influence of pressure at the outlet.
  3. Calculation of the axial pump efficiency.

Other possibilities to be done with this Unit:

  1. Many students view results simultaneously. To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
  2. Open Control, Multicontrol and Real Time Control. This unit allows intrinsically and/or extrinsically to change the span, gains, proportional, integral, derivative parameters, etc, in real time.
  3. The Computer Control System with SCADA and PID Control allow a real industrial simulation.
  4. This unit is totally safe as uses mechanical, electrical and electronic, and software safety devices.
  5. This unit can be used for doing applied research.
  6. This unit can be used for giving training courses to Industries even to other Technical Education Institutions.
  7. Control of the PBAC unit process through the control interface box without the computer.
  8. Visualization of all the sensors values used in the PBAC unit process.
  9. By using PLC-PI additional 19 more exercises can be done.
  10. Several other exercises can be done and designed by the user.
