# PBEC Computer Controlled Gear Pump Bench

## 創新系統

The Computer Controlled Gear Pump Bench, "PBEC", has been designed to obtain the most important characteristics curves and parameters of a gear pump bench.

## 一般說明

The Computer Controlled Gear Pump Bench, "PBEC", is a bench-top unit consists of a gear 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 system of pipes. As the circuit is closed, it prevents a continuous waste of water when working with it.

The Computer Controlled Gear Pump Bench, "PBEC", has instrumentation and sensors to allow the measurement, from the computer, of the most typical parameters of the gear pump:

• Torque.
• Motor speed.
• Total flow driven.

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

• Height of the pump.
• Hydraulic and mechanic power.
• Volumetric 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.
