Amfani da ka'idar kamanceceniya ta famfo
1. Idan aka yi amfani da irin wannan doka ga famfon vane ɗaya da ke gudana a gudu daban-daban, za a iya samunta:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2
Misali:
Akwai famfo, samfurin shine SLW50-200B, muna buƙatar canza SLW50-200B daga 50 Hz zuwa 60 Hz.
(daga 2960 rpm zuwa 3552 rpm)
A mita 50 Hz, bututun yana da diamita na waje na 165 mm da kan mita 36.
H60Hz/H50Hz=(N60Hz/N50Hz)²=(3552/2960)2=(1.2)²=1.44
A mita 60, H60Hz = 36×1.44 = mita 51.84.
A taƙaice dai, kan wannan nau'in famfo ya kamata ya kai mita 52 a gudun 60Hz.
