umthetho
Ukusetshenziswa kwethiyori efanayo yepompo
1. Lapho umthetho ofanayo usetshenziselwa iphampu efanayo ye-vane esebenza ngejubane elihlukile, ingatholakala:
• Q1 / Q2 = N1 / N2
• I-H1 / H2 = (N1 / N2) 2
• I-P1 / P2 = (N1 / N2) 3
• I-NPSH1 / NPSH2 = (N1 / N2) 2
Isibonelo:
Iphampu ekhona, imodeli yi-SLW50-200B, sidinga ushintsho SLW50-200B kusuka ku-50 Hz kuya ku-60 Hz.
(kusuka ku-2960 RPM kuya ku-3552 RPM)
Ku-50 Hz, impeller inobubanzi obungaphandle ka-165 mm nekhanda lama-36 m.
H60hz / h50hz = (N60hz / N50hz) ² = (3552/2960) 2 = (1.2) ² = 1.44
Ku-60 HZ, H60HHZ = 36 × 1.44 = 51.84m.
Ukufingqa, inhloko yalolu hlobo lwepompo kufanele ifinyelele kuma-52m ngejubane le-60hz.
