InfoSurge Pro allows you to create hydraulic transients by providing a curve which will alter pump and valve operations,
00:10
as well as junction demand changes.
00:13
You can then compare the simulation results from different operational conditions.
00:17
In this example, you perform a pump trip analysis using the Pump File option.
00:22
Once the project starts, click the InfoWater Pro tab to open the InfoWater Pro ribbon.
00:29
In the Project panel, click Initialize.
00:32
First, specify the properties of the pump that should be used in the surge analysis.
00:38
With the Select tool active, from the map, select pump 9_PUMP.
00:44
From the Model Explorer, click the Pump Surge Data button to open the Pump/Turbine Surge Data dialog.
00:51
First, enable the Check Valve Installed option to prevent reverse flow through the pump.
00:56
Then, enter a check valve (CV) opening/closing time of 0.01 seconds.
01:03
Enable the Non-Reopen CV option.
01:07
With this option enabled, the check valve will not open if it has already closed or if the pump and check valve start the simulation closed.
01:16
To assign a pump file, enable the Pump File Provided option.
01:20
The available files are a table defining head and torque as a function of flow and speed
01:26
and will be used as the basis for modelling the selected pump during the simulation.
01:31
Expand the associated drop-down and select 0: Pump File #1 (1270/25).
01:38
Note that there are eight files available to choose from.
01:42
The data within the files are based on experimental data.
01:46
If needed, there is a calculator, Pump File Selector, which can help select the most appropriate pump file.
01:52
In the Pump File Settings group box, assign the following values to the corresponding fields:
01:58
Rated Head (ft): 204
02:02
Rated Flow (gpm): 1866
02:07
Inertia: 40
02:09
Efficiency (%): 80
02:12
Rated Speed (rpm): 1800
02:16
Initial Speed Ratio: 1
02:19
This data would typically come from a pump manufacturer for the selected pump.
02:24
When all values are assigned, click Update to save the settings and close the dialog.
02:31
Next, set the Pump Operation Change data.
02:34
From the Model Explorer, click the Pump Operation Change button.
02:39
In the Speed/Wicket Gate Change Data dialog, set the Pump Disturbance Type: drop-down to 1: Trip.
02:46
Assign a trip start time of 2 seconds.
02:50
This means that 2 seconds into the simulation, the pump will run down according to the data specified in the Pump Surge Data dialog,
02:58
where the non-reopen check valve and pump file were selected.
03:02
Click Update to save the changes and close the dialog.
03:06
You are now ready to run a surge analysis.
03:09
From the Model Explorer, click the Run Manager button.
03:12
Or, from the ribbon, on the Analysis panel, click the Run button.
03:17
From the Run Manager dialog, click the Run button to run a surge analysis.
03:23
When the analysis is complete, click OK to close the Run Manager.
03:28
Now, from the ribbon, InfoWater Pro tab, View panel, click Report Manager.
03:34
In the Report Manager dialog, click the New button to open the Output Report/Graph dialog.
03:41
From the Available Output Sources, select *Active*.Surge.
03:46
From the Graph Report tab, select Surge Node Graph, and then click Open.
03:52
Now, select Junction 10 to view its pressure profile.
03:55
Note how the minimum and maximum pressure readings indicate the effects of the pump shutdown.
04:01
Close the Report Manager.
