Intangiriro kumagambo asanzwe ya pompe (4) - Guhuza pompe

amategeko
Gushyira mu bikorwa ibitekerezo bisa na pompe

1. Iyo amategeko nk'aya akoreshwa mu kuvoma ka vane yiruka ku muvuduko utandukanye, urashobora kuboneka:
• Q1 / Q2 = N1 / N2
• h1 / h2 = (n1 / n2) 2
• P1 / P2 = (n1 / n2) 3
• NPSH1 / NPSH2 = (n1 / n2) 2

Urugero:

Ibisanzwe biriho, icyitegererezo ni isahani50-200B, dukeneye guhindura sliw50-200B kuva 50 hz kugeza 60 hz.
(kuva 2960 RPM kugeza 3552 RPM)

Kuri 50 hz, umufasha afite diameter yo hanze ya mm 165 numutwe wa m 36 m.

H60hz / h50hz = (n60hz / n50hz) ² = (3552/2960) 2 = 1.2) ² = 1.44
Kuri 60 HZ, H60Hz = 36 × 1.44 = 51.84m.
Kuri Guverinoma, umutwe wubwoko bwa pompe ugomba kugera kuri 52m kumuvuduko wa 60hz.
