Modeling a File Type Pump for Use with a Pump Trip
TIMESTAMPS
0:10 File type pumps are reviewed.
0:25 The word, "File" refers to an underlaying diagram used to model a pump trip: 20 different pump files (i.e., pump types) available, only used in modelling trips.
1:40 Unique data for file-type pumps: Efficiency, File #, Rated Head, Rated Flow, Rated Speed, Inertia.
2:05 For info on parallel and pump resistance, see the video, "Modeling Standard (Table) Pumps in KYpipe and Surge."
2:12 Review of Elevation and Grade settings.
3:04 Rated Head and Rated Flow.
3:48 Rated Speed at an operating point.
3:50 To get the pump File Number and Inertia, use the built-in tool under Tools, Select Pump File/Calculate Inertia.
5:45 Now look at File-Table Pump: the only difference is how data is entered. For a File-Table type pump, the curve data are entered into the pump ID.
6:22 Advanced Tip - Surge and steady-state results will not match when using a file-type pump to model a pump trip.
