Chiyambi cha mawu a pampu wamba (4) - Kufanana kwa pampu

lamulo
Kugwiritsa ntchito chiphunzitso chofanana cha mpope

1. Chilamulo chofananachi chikagwiritsidwa ntchito papampu yomweyi yomwe ikuyenda pa liwiro losiyana, itha kupezeka:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2

Chitsanzo:

Pampu yomwe ilipo, chitsanzo ndi SLW50-200B, tifunika kusintha SLW50-200B kuchokera ku 50 Hz kupita ku 60 Hz.
(kuchokera 2960 rpm mpaka 3552 rpm)

Pa 50 Hz, choyikapocho chimakhala ndi m'mimba mwake wa 165 mm ndi mutu wa 36 m.

H60Hz/H50Hz=(N60Hz/N50Hz)²=(3552/2960)2=(1.2)²=1.44
Pa 60 Hz, H60Hz = 36×1.44 = 51.84m.
Pomaliza, mutu wa mpope wamtunduwu uyenera kufika 52m pa liwiro la 60Hz.
