umthetho
Ukusetshenziswa kwethiyori yokufana kwephampu
1. Uma umthetho ofanayo usetshenziswa empompini efanayo ye-vane egijima ngesivinini esihlukile, ingatholakala:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2
Isibonelo:
Iphampu ekhona, imodeli yi-SLW50-200B, sidinga ukushintsha i-SLW50-200B isuka ku-50 Hz iye ku-60 Hz.
(kusuka ku-2960 rpm ukuya ku-3552 rpm)
Ku-50 Hz, i-impeller inobubanzi obungaphandle obuyi-165 mm nekhanda elingu-36 m.
H60Hz/H50Hz=(N60Hz/N50Hz)²=(3552/2960)2=(1.2)²=1.44
Ku-60 Hz, H60Hz = 36×1.44 = 51.84m.
Ukufingqa, ikhanda lalolu hlobo lwepompo kufanele lifinyelele ku-52m ngesivinini esingu-60Hz.
