Fluid Mechanics TurbomachinesMulti-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. -

Oil Pump Supply Module
The is part of an equipment series that facilitates the investigation of a wide range of engines and machines. Different oil pumps can be operated on the supply module and investigated in terms of their characteristic behaviour. The pumps are connected into the experimental set-up using hydraulic hoses with quick action couplings. The flow is adjusted on a pressure valve and recorded using an oval wheel meter. Other sensors measure the temperature, intake and delivery pressure. The corresponding sensor connections and digital displays are located on the measuring equipment block. All measured data can be transferred to a PC for further processing. The drive motor for operation of the pumps is located on the universal unit.

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.

Pump and Turbine Trainer
Using the Basic Unit, Pump and Turbine Trainer, an extendable experimental concept for basic experiments in the area of hydraulic fluid-flow machines has been realised. Here the forms the basic unit. Equipped with a powerful centrifugal pump and a sealed water circuit with an own supply tank, the module can be used to perform experiments on pumps. Rotational speed, flow rate and back-pressure can be adjusted. The drive power of the pump is determined using the rotational speed and the torque. Modern electronic measuring instruments and digital displays for pressure, flow rate, torque and rotational speed are integrated into the basic unit. Easy to interchange sets with various types of water turbines enable the range of experiments to be expanded to include experiments on turbines

Series / Parallel Pumps
The series and parallel pump test rig is system that has been designed for instructional and experimental use in vocational schools, special colleges and universities. The series and parallel pump test rig can be used, for example, to clarify the differences between serial and parallel operation of two pumps. The test stand includes two identical centrifugal pumps that are driven by speed-controlled DC shunt motors. The speed of the motors is clearly shown on the switch box, together with the current and voltage. The motors are suspended. The driving torque is determined with a torque wrench. The pressure is measured on the intake and delivery side of the pump with manometers. The flow rate in the system is displayed by a water meter. It can also be determined by measuring the differential pressure at a nozzle or orifice.

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.

Side Channel Pump
The test stand is used for investigating the pump characteristic of centrifugal pumps and for process-related measurement exercises. The heart of the system is a small centrifugal pump with a speed-regulated drive. The flow can be measured either with a magneto-inductive flow meter, or using a venturi nozzle and differential pressure transducer. Absolute pressure transducers are provided for measuring the pressures on the intake and delivery sides of the pump. The water temperature is determined using a resistive measuring sensor. The flow rate in the system can be adjusted using ball-cocks. The controls and digital displays are installed in a switch box, this also has a PC interface. Thanks to the data acquisition card and software supplied, the measured data can be displayed, processed and stored on a PC.

Turbine Supply Module
This is a part of an equipment series that facilitates the investigation of a wide range of engines and machines. Different turbines can be operated and studied with this supply module. The turbines are connected to the water circuit using a flexible hose. A powerful centrifugal pump supplies pressurised water to drive the turbine under test. All relevant measured values are acquired using sensors and are displayed on the measuring unit of the supply module. The data acquisition software enables the measured values to be further processed on a PC.
The Universal Drive and Brake Unit is used as a generator to load the turbine. -

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.
