Ngwa nke echiche myirịta nke mgbapụta
1. Mgbe a na-etinye iwu yiri nke ahụ na otu mgbapụta vane na-agba ọsọ na ọsọ dị iche iche, enwere ike nweta ya:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2
Ọmụmaatụ:
Igwe mgbapụta dị adị, ihe nlereanya bụ SLW50-200B, anyị chọrọ mgbanwe SLW50-200B site na 50 Hz ruo 60 Hz.
(site na 2960 rpm ruo 3552 rpm)
Na 50 Hz, impeller nwere mpụta dayameta nke 165 mm na isi nke 36 m.
H60Hz/H50Hz=(N60Hz/N50Hz)²=(3552/2960)2=(1.2)²=1.44
Na 60 Hz, H60Hz = 36×1.44 = 51.84m.
Iji chịkọta ọnụ, isi nke ụdị mgbapụta a kwesịrị iru 52m na ọsọ 60Hz.
