Ukusetshenziswa kwemfundiso yokufana kwephampu
1. Uma umthetho ofanayo usetshenziswa kuphampu efanayo ye-vane esebenza ngesivinini esihlukile, ungatholakala:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2
Isibonelo:
Njengoba kukhona iphampu, imodeli iyi-SLW50-200B, sidinga ushintsho lwe-SLW50-200B kusuka ku-50 Hz kuya ku-60 Hz.
(kusukela ku-2960 rpm kuya ku-3552 rpm)
Ku-50 Hz, i-impeller inobubanzi bangaphandle obungu-165 mm kanye nekhanda elingamamitha angu-36.
H60Hz/H50Hz=(N60Hz/N50Hz)²=(3552/2960)2=(1.2)²=1.44
Ku-60 Hz, i-H60Hz = 36×1.44 = 51.84m.
Ngamafuphi, ikhanda lalolu hlobo lwephampu kufanele lifinyelele kumamitha angu-52 ngesivinini esingu-60Hz.
