1 Introduction

The G.U.N.T. HM 291Axial Flow Impeller Turbine Unit with

PC Data Acquisition is part of an equipment series that

facilitates the investigation of a wide range of hydraulic engi-

nes and machines such as pumps, fans and water turbines.

All demonstration units in this range are equipped with

electronic sensors for PC data acquisition.

In addition to the demonstration unit, the HM290 TurbineService Unit, an Interface Module and a PC Data Acquisition

Card with analysis software are required. This set-up permits

the measured values to be displayed graphically and also

facilitates the recording of characteristic curves.

Using the HM291 demonstration unit, the characteristic be-

haviour of a water turbine (impulse-type turbine) can be

determined.

- Power as a function of volumetric flow rate, pressure and

speed

- Recording of torque characteristic

- Determination of the turbine efficiency

The system is suitable for both practice-related training in

vocational colleges and for laboratory experiments in techni-

cal colleges and universities.

The system is only intended to be used for training and

experimental purposes.AllrightsreservedG.U.N.T.

To create a new curve you must first define the

measured variables that are to be displayed. Use

button (9) for this.

A list of available measured variables is then dis-

played. Whereas you can only select one variable

for the abscissa (x axis , up to four different varia-

bles can be displayed simultaneously for ordinates(y axis). This permits almost any imaginable shape

to be displayed.

Then, you must assign a name to the curve. You

can do this using button (4). A dialog window then

opens in which you can input the curve name and

any other comments that you wish to make.

Now you can initiate the actual recording of the

measured values. A crosshair indicates the current

measured value(s). If these measured values are

satisfactory and stable you can use button (6) toadd a new measuring point to the curve. The

measuring points do not have to be in a single row

for this Additional measuring points are added in

the magnitude of the x axis. If you wish to delete a

measuring point, first select it using (3) and then

click button (5). The current x value is displayed.

You can have more than one curve drawn in the

same diagram simply by creating a new curve

using (4). If there is more than one curve in the

diagram you can use button (1) to activate the

curve you wish to edit. This allows other measuring

points to be subsequently added.

Using (7) you can print out curves; use (8) to print

out measured values in table format.

Use menu item file(10) to save plots to a file.

window using the mouse button and then entering

new scale limit values.

5.1.1 Software Calculations

The following calculations are performed by the

software.

The flow is measured by a turbine over its charac-

teristic curve for flow/ frequency.

The mechanical useful output power for the turbine

is calculated from the torque (in Ncm) and speed

(in rpm):

Pmech

=2

60100Mn in W

The hydraulic output power for the turbine is calcu-

lated from the pump head (in bar) and the pumping

flow rate (in l/min):

Phyd=100

.

in W.

The efficiency level is yielded from the ratio of

mechanical useful output power to the hydraulic

input power:

5.2 Recording the turbine characteristic curve

Torque, power and efficiency level are applied

over speed to determine the turbine characteristic

curve. The flow rate remains constant for this.

- Switch on the interface module.

- Close the ball cock on the HM290 completely.

- Switch on pump HM290.

- Using the ball cock, adjust the flow rate and

pressure to the required levels.

- Loosen the adjusting screw for the turbine bra-

ke completely and record the first measuring

point without any load applied. The turbine is

running at maximum speed.

- Increase the load gradually using the adjusting

screw and record the subsequent measuring

points. When doing this, wait for the measured

value to achieve a steady state.

- Finally, increase the load until the turbine locksup. The characteristic curve is then completely

recorded.

Recording of the turbine characteristic curve can

then be repeated for other flow rates.

Different characteristic curves are obtained when

the torque or flow rate is varied while speed is kept

constant.

5.3 Results

You can print out the stored test results.

The name of the student and the date can be

entered in the headers of the print-outs.

The following figure shows a graphic of the turbine

characteristic curves. In the example presented

here, the stored test results file was loaded into

ExcelTM.

Flow was full out for this test.

The torque characteristic curve decreases as it is

typical for water turbines at higher speed. But the

characteristic curve it not straight as per theory. At

zero torque the turbine reaches its no-load speed

of arround 5100 rpm. The maximum torque of

around 5 Ncm is reached at around 1000 rpm.

The power output curve indicates the turbines

maximum power of 12W over a relatively broad

range of speed.

At this speed, the turbine also achieves its maxi-

mum efficiency of nealy 25%. At this speed the

water leaves the runner with a minimum of lost and

the output loss reaches a minimum. The direction

of water flow can be clearly observed due to the

transparent housing. The low efficiency can be

explained by the relatively high losses in four small

nozzles and a lot of friction in the lines and hoses.

The test results can also be printed out as a table

with numeric values.
