Ngwa nke myiri ike nke mgbapụta
1. Mgbe a na-etinye iwu yiri ya na otu mgbapụta vane na-agba na ọsọ dị iche iche, a ga-enweta ya:
• Q1 / Q2 = N1 / N2
• H1 / H2 = (N1 / N2) 2
• P1 / P2 = (N1 / N2) 3
• NPSH1 / NPSH2 = (N1 / N2) 2
Ihe Nlereanya:
Dị na mgbapụta, ihe atụ ahụ bụ slw50-200b, anyị kwesịrị ịgbanwe slw50-200-200-200t site na 50 hz.
(site na 2960 rpm rue 3552 rpm)
Na 50 hz, onye na - emepụta ihe nwere dayameta 165 mm na isi nke 36 m.
H60Hz / H50Hz = (N50HZ) ² = (3552/2960) 2 = (1.2) ² = 1.44
Na 60 Hz, H60Hz = 36 × 1.44 = 51.84m.
Nchịkọta, isi ụdị ụdị mgbapụta a kwesịrị iru 52m na 60hz ọsọ.
