PBSPC Werkbank für serien-/ parallelgeschaltete Pumpen, computergesteuert.

The Computer Controlled Series/Parallel Pumps Bench, "PBSPC", is designed to demonstrate the operational advantages of parallel or series operation, depending on the required duty.

This unit consists of two centrifugal pumps, a feed water tank, circulation pipes, regulation valves, three pressure sensors and a flow sensor.

The centrifugal pumps can operate: alone, coupled in series or in parallel. A three-phase motor activates a pump with possibility of adjustment and measurement of the turn speed as well as the transmitted mechanic torque, and a single-phase motor activates the other pump.

The pumps are installed in a pipes system, which, as it is a closed circuit, avoids the permanent waste of water during the operation.

By the appropriate positioning of the valves it is possible to connect the pumps individually, in series or in parallel, depending on which test is going to be performed.

The "PBSPC" 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 power.
• Mechanic power.
• Efficiency.

Adjustable parameters, as:

• Motor speed and flow.
• Position of the valves.

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.
