sharciga
Codsiga aragtida isku midka ah ee bamka
1. Marka sharciga la midka ah lagu dabaqo isla bamamka vane-ga oo ku socda xawaare kala duwan, waxaa la heli karaa:
•Q1/Q2=n1/n2
•H1/H2=(n1/n2)2
•P1/P2=(n1/n2)3
•NPSH1/NPSH2=(n1/n2)2
Tusaale:
Bamka jira, qaabku waa SLW50-200B, waxaanu u baahanahay beddel SLW50-200B laga bilaabo 50 Hz ilaa 60 Hz.
(laga bilaabo 2960 rpm ilaa 3552 rpm)
At 50 Hz, impeller wuxuu leeyahay dhexroor dibadda 165 mm iyo madaxa 36 m.
H60Hz/H50Hz=(N60Hz/N50Hz)²=(3552/2960)2=(1.2)²=1.44
60 Hz, H60Hz = 36×1.44 = 51.84m.
Marka la soo koobo, madaxa bamka noocaan ah waa inuu ku gaaro 52m xawaarihiisa 60Hz.
