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

lamulo
Kugwiritsa ntchito chiphunzitso chofanana cha pampu

1. Pamene lamulo lofananalo likugwiritsidwa ntchito pa pampu yomweyi ya vane yomwe ikuyenda pa liwiro losiyana, lingapezeke:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2

Chitsanzo:

Pompo ilipo, chitsanzocho ndi SLW50-200B, tikufunika kusintha SLW50-200B kuchoka pa 50 Hz kufika pa 60 Hz.
(kuyambira 2960 rpm mpaka 3552 rpm)

Pa 50 Hz, impeller ili ndi mainchesi akunja a 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.
Mwachidule, mutu wa pampu yamtunduwu uyenera kufika mamita 52 pa liwiro la 60Hz.
