He kupu whakataki ki ngā kupu papu noa (4) – Te āhua ōrite o te papu

ture
Te whakamahinga o te ariā ōrite o te papu

1. Ina whakamahia te ture ōrite ki te papu vane kotahi e rere ana i ngā tere rerekē, ka taea te whiwhi:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2

Tauira：

He papu kei mua, ko te tauira ko SLW50-200B, me whakarerekē te SLW50-200B mai i te 50 Hz ki te 60 Hz.
(mai i te 2960 rpm ki te 3552 rpm)

I te 50 Hz, ko te diameter o waho o te impeller he 165 mm, ā, ko te pane he 36 m.

H60Hz/H50Hz=(N60Hz/N50Hz)²=(3552/2960)2=(1.2)²=1.44
I te 60 Hz, H60Hz = 36×1.44 = 51.84m.
Hei whakarāpopototanga, me eke te pane o tēnei momo papu ki te 52m i te tere 60Hz.
