PBRC Banco de Bomba de Pistão, Controlado por Computador (PC)

The Computer Controlled Piston Pump Bench, "PBRC", is a bench-top unit that consists of a piston pump, a feed tank, flow meter tank calibrated for taking flow measurements, circulation pipes, manual valves and a solenoid valve, computer controlled, as well as the enough control elements for the pump experiments: two pressure sensors and two level switches.

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 Piston Pump Bench, "PBRC", unit has instrumentation and sensors to allow the measurement, from the computer, of most representative parameters of the piston pump:

• Admission and discharge pressure.
• Torque.
• Motor speed.

The software allows to calculate, with the measurement of the parameters:

• Total flow driven.
• Height of the pump.
• Hydraulic and mechanic power.
• Volumetric efficiency.

The unit includes the typical items a piston pump should have, such as: relief valve and damping chamber.

So one of the most important objetives of this unit is to study the influence that the presence of the damping chamber has.

The flow meter tank has a drain with a solenoid valve, computer controlled, to facilitate the discharge of the water into the feed tank, in case the water level in the flow meter tank is too high.

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.
