General Description

The Computer Controlled Centrifugal Pump Bench, "PBCC", is a bench-top unit consists of a centrifugal pump computer controlled, a feed water tank, circulation pipes, regulation valves, as well as the enough control elements for the pump experiments: two pressure sensors and a 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 pipes system which avoids the permanent water spending during the operation because it is a closed circuit.

The Computer Controlled Centrifugal Pump Bench, "PBCC", unit has instrumentation and sensors to allow the measurement, from the computer, of the most typical parameters of the centrifugal pump:

• Speed motor.
• 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.
