mutemo
Kushandiswa kwedzidziso yekufanana kwepombi
1. Kana mutemo wakafanana uchishandiswa kune imwechete vane pombi inomhanya nekumhanya kwakasiyana, inogona kuwanikwa:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2
Muenzaniso:
Pombi iripo, modhi iSLW50-200B, tinoda shanduko SLW50-200B kubva pa50 Hz kuenda pa60 Hz.
(kubva pa2960 rpm kusvika 3552 rpm)
Pa50 Hz, impeller ine dhayamita yekunze ye 165 mm uye musoro we 36 m.
H60Hz/H50Hz=(N60Hz/N50Hz)²=(3552/2960)2=(1.2)²=1.44
Pa60 Hz, H60Hz = 36×1.44 = 51.84m.
Kupfupisa, musoro werudzi urwu rwepombi unofanirwa kusvika 52m pa60Hz kumhanya.
