Codsiga aragtida la mid ah ee matoorka
1. Marka sharciga la midka ah lagu dabaqayo si ka mid ah matoorka vane ee ku shaqeeya xawaare kala duwan, waa la heli karaa:
• Q1 / Q2 = N1 / N2
• H1 / H2 = (n1 / n2) 2
• p1 / p2 = (n1 / n2) 3
• NPSH1 / NPSH2 = (n1 / n2) 2
Tusaale:
Sawirka jira, moodalku waa SLW50-200B, waxaan u baahan nahay beddel SLW50-200b oo ka socda 50 Hz ilaa 60 Hz.
(laga bilaabo 2960 rpm ilaa 3552 rpm)
50 Hz, Qalabka damaca ayaa leh dhexroor ka mid ah 165 mm oo madax ah 36 m.
H60hz / h50hz = (n60hz / n50hz) ² = (3552/2960) 2 = (1.2) ² = 1.44)
60 Hz, H60hz = 36 × 1.44 = 51.84m.
Isku soo wada duuboo, madaxa matoorka noocan ah waa inuu gaaraa 52m xawaare ka socda.
