Kuchita Kwapamwamba V Mpira Valve
Chidule
Kudulidwa kwa V kuli ndi chiŵerengero chachikulu chosinthika ndi chiwerengero chofanana cha kutuluka, kuzindikira kulamulira kokhazikika kwa kuthamanga ndi kutuluka.
Kapangidwe kosavuta, voliyumu yaying'ono, kulemera kopepuka, njira yoyenda yosalala.
Kupereka ma wrth lalikulu nati zotanuka zolipirira zodziwikiratu kuti ziwongolere bwino nkhope yosindikiza ya mpando ndi pulagi ndikuzindikira kusindikiza kwabwino. Pulagi ya eccentric ndi mapangidwe a mipando amatha kuchepetsa kuvala.
Kudula kwa V kumapangitsa kuti pakhale mphamvu yometa mphero kuti itseke media yomwe ili ndi ulusi. Ndikoyenera makamaka kutsegula ndi kulamulira zofalitsa za kukhuthala kwakukulu ndi zofalitsa zomwe zimakhala ndi ulusi ndi ma granules.
