Ukusetyenziswa kwethiyori yokufana kwempompo
1. Xa umthetho ofanayo usetyenziswa kwimpompo ye-vane efanayo esebenza ngezantya ezahlukeneyo, inokufumaneka:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2
Umzekelo:
Ipompo ekhoyo, imodeli yi-SLW50-200B, sifuna utshintsho lwe-SLW50-200B ukusuka kwi-50 Hz ukuya kwi-60 Hz.
(ukusuka ku-2960 ukuya ku-3552 rpm)
Kwi-50 Hz, i-impeller inobubanzi obungaphandle be-165 mm kunye nentloko ye-36 m.
H60Hz/H50Hz=(N60Hz/N50Hz)²=(3552/2960)2=(1.2)²=1.44
Kwi-60 Hz, i-H60Hz = 36 × 1.44 = 51.84m.
Ukushwankathela, intloko yolu hlobo lwempompo kufuneka ifikelele kwi-52m ngesantya se-60Hz.
