  Two-Stage Axial – Flow Fan

  The was designed for measuring the fan characteristic curve of a two-stage axial fan. For this purpose 2 identical, speed regulated fans are fitted in a pipe. Connections for differential pressure measurement are fitted at appropriate points. Temperature and pressure are measured electronically before and after each stage. A 3-hole sensor with position measurement facilitates the measurement of speed distributions at impellers and guide wheels. In addition, speed and flow rate are measured. For comparison to the fans connected in series, the fans can also be operated separately. The fans each have individually adjustable blades and a guide wheel. All measured data is displayed on the unit and can be processed in other applications by means of the PC data acquisition.

  Pump And Compressor Unit

  The modular system allows the investigation of different machines (reciprocating machines and turbomachines). Each machine is mounted on a base plate, which can easily be fitted into the unit. It is powered by a belt drive. Hoses with quick-action couplings provide the supply lines. The unit itself includes the electric drive motor with speed control, 2 pressure vessels for the compressor experiments, a measuring tank and a supply tank for the pump experiments and a protection cover. The intake and delivery pressure, temperature, motor speed and power are measured and displayed digitally. The corresponding flow is measured indirectly and transferred to the PC data acquisition software.

  Multi-Pump Trainer

  The represents a closed system for training and experiments that is equipped with all the necessary measuring devices. The test rig is equipped with 4 pumps, provision is made for the installation of an additional pump of any type. The pumps fitted comprise 2 identical centrifugal pumps with adjustable speed DC shunt wound motors, a self-priming side channel pump with single phase AC motor, and a reciprocating pump with a single phase AC motor. Manometers on the suction and delivery side of the pumps indicate the relevant pressures in the system. The flow is indicated by a water meter. Volumetric flow rate measurement can be made using the stop watch included. The rotational speed of the drive motors is determined using a handheld tachometer. Current and voltage to the drive motors are indicated in easy to read form on the switch box associated with the test rig. The power regulator for controlling the speed of the DC motors is also to be found there. Torque is determined using a torque wrench with gauge; with the aid of the wrench a counter torque is placed on the shafts of the motors installed as pendulum mechanisms, the torque can then be read off. In this way the provides a wide range of measured data that makes it possible to address key problem areas in pump technology. Due to the closed water circuit and supply from an own
  tank, the test rig is independent of the water mains.

  Series / Parallel Pumps / PC

  The Pump Test Rig was developed for the serial and parallel operation of 2 centrifugal pumps. It is used predominantly for determining pump and system characteristic curves. The measured data is recorded electronically during the experiments. This makes it possible to display and process the data on a PC. At the same time, the measured data is displayed on easy to read digital displays. This allows operation without a PC connected. The test rig basically comprises 2 identical centrifugal pumps that are driven using DC shunt wound motors of adjustable speed. Proximity switches measure the speed of the motors, force transducers on the motor shafts determine the output torque. At all key points on the unit, the pressure is determined using absolute pressure transducers, the flow rate is measured using a magnetic-inductive sensor.
