Intangiriro kumagambo asanzwe ya pompe (4) - Guhuza pompe

amategeko
Gushyira mu bikorwa ibitekerezo bisa na pompe

1. Iyo amategeko asa nayo akoreshwa kuri pompe imwe ikora kumuvuduko utandukanye, irashobora kuboneka:
• Q1 / Q2 = n1 / n2
• H1 / H2 = (n1 / n2) 2
• P1 / P2 = (n1 / n2) 3
• NPSH1 / NPSH2 = (n1 / n2) 2

Urugero ：

Kubaho pompe, moderi ni SLW50-200B, dukeneye guhindura SLW50-200B kuva 50 Hz ikagera kuri Hz 60.
(kuva 2960 rpm kugeza 3552 rpm)

Kuri 50 Hz, uwimuka afite diameter yo hanze ya mm 165 n'umutwe wa m 36.

H60Hz / H50Hz = (N60Hz / N50Hz) ² = (3552/2960) 2 = (1.2) ² = 1.44
Kuri 60 Hz, H60Hz = 36 × 1.44 = 51.84m.
Kurangiza, umutwe wubwoko bwa pompe ugomba kugera kuri 52m kumuvuduko wa 60Hz.
