If the pump outlet is changed from 6" to 4" by a joint, will this have any impact on the pump? In real projects, we often hear similar requests. Kuchepetsa kupusa kwamadzi kwa pampu kumatha kuwonjezera kuthamanga kwa madzi, koma chifukwa chowonjezeka cha pampu, chimawonjezera kuchepa kwa hydralic.
Reducing the water outlet of the pump is actually equivalent to closing the outlet valve of the pump. Reducing the outlet diameter is equivalent to increasing the local resistance coefficient. Kutsatira mtundu wa Darcy-Weisbach, kukakamizidwa kwa dongosolo kumatha kulumpha osagwirizana (kutsimikizira kuwonetsa kuti kuchepetsa 10%% yowonjezera), pomwe kuchuluka kwake kumawonetsa lamulo la qíable Valuminika.
Ngakhale kuti mphamvu ya shaft imachepera pafupifupi 8-12% ndi kuchepa kwamphamvu, kulimba mtima kwamphamvu komwe kumachitika chifukwa cha kuchuluka kwa mipweya kungawonjezere ndi 20-30%, makamaka pafupi ndi nthawi yovuta kwambiri.
Mphamvu yopumira imawonjezera kukakamiza kwapampu: pomwe dongosolo lomwe likugwira ntchito mogwirizana ndi HQ Cluve ndi malo osinthira pa neipe neipe dechin, ndi zolosera zamphamvu zimafunikira kudzera mu kupindika.
Ngati njira yotetezera idapitilira, kuyenda kwamadzi osauka kumabweretsa kukakamizidwa pampu yamadzi, kumawonjezera katundu, ndipo galimoto idzadzaza. Ngati ndi kotheka, mphamvu ya votix iyenera kuloseredwa mu cfd kuyerekezera, ndipo kuyamwa kameneka kuyenera kuphatikizidwa ndi maluwa opanga kuti muwonetsetse kuti mtengo wamagalimoto amayendetsedwa pansipa 85% ya mtengo wovota.
Zimakhudza mwachindunji kuyenda kwa pampu yamadzi, komwe kuli kokulirapo madzi a pampu yamadzi, kuyenda kwa pampu yamadzi, komanso mosemphanitsa. (Kuthamanga koyenda kumalumikizidwa ndi malo ogulitsira madzi. Kuyeserera kumawonetsa kuti kuchepetsa 10% mu diameter kumafanana ndi Kuchepetsa kwa 17-19%)
