Valavu kulamulira ndi mtundu wa vavu zomwe lapeza linafalitsidwa kwambiri ntchito m'mafakitale zosiyanasiyana. chipangizo angagwiritsidwe ntchito ngati kutentha Mtsogoleri yosavuta kapena mbali ya zovuta dongosolo ndondomeko kulamulira mu mode yaotomatiki. Kaya zimenezi, mfundo yofunika kwambiri ndi kusankha vavu.
Ngati valavu ulamuliro amasankhidwa molondola, izi adzaonetsetsa osati mulingo woyenera kulamulira molondola, komanso zosavuta kupewa mavuto monga kukokoloka ndi mkulu phokoso mlingo. Nthawi zina, vavu ali bandiwifi kuti amadziwa mogwirizana ndi ntchito pa dzanja, ndi kuti kuchepetsa mlingo phokoso ayenera mitundu ya zolimba kukhala akuluakulu awiri mwadzina mukonda.
Valavu kupewa kovuta kukatenga chifukwa chakuti m'pofunika yolumikizana zingapo zofunika kuti Kwenikweni, ndi matanthauzo ofananafanana. Kusankha valavu ndi otsika-bandiwifi kapena m'matangadza ake zotsala chingakhale chifukwa cha mavuto kwambiri. Ngati valavu kulamulira ali ndi bandiwifi waukulu kwambiri, zimenezi zimapangitsa kuti mfundo kuti sasamalira mlingo woyenera molondola kulamulira. Ichi ndi chifukwa chakuti valavu tsinde kudzalimbikitsa mtunda yaing'ono (osaonekera poyerekeza ndi sitiroko zonse). zolakwa amenewa nthawi zambiri amachititsa kuti Kusakhazikika kwa dongosolo lonse, komanso kulephera kwa onse valavu ndi galimoto lonse. Nthawi zina valavu ulamuliro amusankha kuti kuthamanga dontho kudutsa chipangizo linali lotsegula pazipita kuti vutoli makamaka kwa mlingo waukulu nthunzi otaya. Ngati ife kulankhula za Zochita izi zikutanthauza kuti kusankha ikuchitika pa dontho vavu kuthamanga.
An chizindikiro zofunika kuti ayenera kutsogoleredwa posankha vavu nthawi, ndi phokoso. valavu ayenera anasankha kuti utsi mathamangidwe nthunzi pa kubwereketsa si upambana 30% ya liwiro la phokoso. chizindikiro ichi kawirikawiri kuposa chifukwa chakuti awiri mwadzina valavu ndi laling'ono kwambiri, ndi mmene chishalo ali ndi mphamvu ndithu. Tseka-kutali ndi malamulo vavu angakhale ndi kapangidwe chapadera chimene chimathandiza kuchepetsa kwambiri mlingo phokoso. Mu mayunitsi amenewa awiri chishalo-pulagi akuimira mu mawonekedwe a yamphamvu perforated, zomwe zayamba kumachepetsa phokoso ndi cavitation Sachita (pamene valavu ntchito mu madzi).
Vavu kusankha, zinadziwika, ayenera kuchitidwa ndi lamulo nkhani ndithu ya zinthu, zomwe kwambiri complicates ndondomekoyi. Njira yodalirika kupewa mavuto ndi kutembenukira kwa WOPEREKA kumukhulupirira, ndi akudziwa chokwanira. Izi kumulola kupereka kasitomala khalidwe mankhwala pazipita. Nkofunika kulabadira mfundo zina, pakati womwenso kuti: mbiri ya Mlengi, woyenerera wa valavu kwa kukonza, n'zotheka kusintha mphamvu kapena ntchito valavu, komanso magawo ena kuti bwanji magwiritsidwe antchito.
