PENGARUH PERUBAHAN KECEPATAN TERHADAP KARAKTERISTIK POMPA SENTRIFUGAL

Sari

Usage of pump as a supply irrigate especially boiler for the activator of turbine require to have capacities, high depress, even BHP (breake horse power), able to measured or constant. Degradation and increase of rotation will cause at pump characteristic change goodly, capacities, head, and BHP require to be conducted by effort, so that pump rotation earn electrics pressure constant decreased also cause at degradation of speed.
This research aim to to know influence of speed turn around to characteristic pump sentripugal. Approach taken by test 2 pump of sentripugal with speed turn around variedly equal to 50 Rpm ( giration of permenit) as follows: 3250 rpm, 3200 rpm, 3150 rpm, 3100 rpm, 3050 rpm, 3000 rpm, 2950 rpm, 2900 rpm, 2850 rpm, 2800 rpm, 2750 rpm, 2650 rpm, 2600 rpm, 2250 rpm, 2550 rpm which is the each tested with the same time. To know influence between speed turn around with characteristic pump hence used with regretion analysis.
This analysis is obtained that change of speed have an effect on proportional to yielded capacities, change of speed have an effect on rank two quadratic to high depress which yielded and change of speed have an effect on rank 3 to yielded axis energy. Whereas constant pump efficiency.
