Pump characteristics for parallel and series configuration: Investigation of the behaviour of two identical centrifugal pumps in operation, system control via PLC.

Features:

• operation of centrifugal pumps in parallel and series configuration, plant control using an integrated PLC, integrated router for operation and control via an end device and for screen mirroring on up to 10 end devices: PC, tablet, smartphone.

• Learning objectives/ experiments: investigate behaviour of centrifugal pumps in operation, recording pump characteristics, recording system characteristics, determining efficiency, investigation of series and parallel configuration of pumps, starting up and shutting down pump systems, screen mirroring: mirroring of the user interface on up to 10 end devices, menu navigation independent of the user interface shown on the touch screen, different user levels available on the end device: for observing the experiments or for operation and control.

Specification:

• trainer with 2 centrifugal pumps which are operated in series or parallel configuration

• plant control with PLC, operation via touch screen

• integrated router for operation and control via an end device and for screen mirroring: possible to mirror the user interface on up to 10 end devices

• closed water circuit

• drive motors with adjustable speed

• motor with pendulum bearing, torque measurement via lever arm and force sensor

• inductive speed sensor on the motor

• electromagnetic flow meter

• data acquisition via PLC on internal USB memory, access to stored measured values via WLAN with integrated router/ LAN connection to customer's own network.
