Anthu ambiri ogwiritsa ntchito vacuum pump amakayikira akamaganizira zowonjezerafyuluta ya fumbi, nthawi zambiri amada nkhawa ndi funso limodzi: mukayika fyuluta, kodi liwiro la kupopa lidzachepa? Nkhawa imeneyi ndi yomveka bwino.
Kuchokera pamalingaliro a chiphunzitso, nkhawa iyi si yolondola. Fyuluta ya fumbi imakhala ndi fyuluta, ndipo mpweya uyenera kudutsa mu ulusi wa chinthu ichi usanalowe mu pampu ya vacuum. Izi zikufanana ndi mpweya womwe umadutsa mu ukonde wokhuthala, womwe ungakumane ndi kukana kwina. Kukana kumeneku kungapangitse kuti mpweya usayende bwino, kotero kwenikweni, kuwonjezera fyuluta kungakhudze liwiro la kupopa mpaka pamlingo wina.
Komabe, kukula kwa zotsatira izi kumadalira kwambiri ngati wogwiritsa ntchitoyo ali ndianasankha bwino kusalala kwa kuseferaya fyuluta. Kusalala kwa kusefa kumatanthauza kukula kwa tinthu tating'onoting'ono komwe fyuluta ingathe kugwira. Kulondola kwambiri kumatanthauza ma pores ocheperako pakati pa ulusi wa fyuluta, zomwe zimapangitsa kuti mpweya ukhale wolimba pamene mpweya ukudutsa. Mosiyana ndi zimenezi, kulondola kochepa kumatanthauza ma pores akuluakulu komanso kukana kochepa.
Ndiye kodi munthu angasankhe bwanji kusalala koyenera kwa kusefera? Yankho lake limadalira momwe fumbi lilili pamalo ogwirira ntchito. Ngati tinthu ta fumbi ndi tating'onoting'ono,kusalala kwa kusefa kotsikandikokwanira kupereka chitetezo chokwanira pamene kuchepetsa kukhudzidwa kwa liwiro la kupopa. Kumbali inayi, ngati fumbi lili losalala kwambiri ndipo likuika pachiwopsezo chachikulu pa pampu, kusalala kwakukulu ndikofunikira - ndipo kukhudzidwa kogwirizana ndi kuthamanga kwa kupopa kumakhala kusinthana kovomerezeka kwa chitetezo cha pampu.
Mwachizolowezi, pansi pa mikhalidwe yambiri yogwirira ntchito, chosankhidwa bwinofyulutaili ndi zotsatira zochepa chabe pa liwiro la kupopa. Mapampu ambiri otulutsa mpweya amapangidwa ndi malire enaake a magwiridwe antchito, ndipo kukana pang'ono kumeneku sikukhudza kwambiri magwiridwe antchito a zida zonse. M'malo mwake, ngati wogwiritsa ntchito asankha kusayika fyuluta ya fumbi chifukwa cha nkhawa yokhudza liwiro la kupopa, fumbi lidzalowa mu pampu mwachindunji, zomwe zimapangitsa kuti zinthu zofunika kwambiri monga ma impeller, ma rotor, ndi zisindikizo ziwonongeke. Pakapita nthawi, magwiridwe antchito a pampu adzachepa, ndipo pazochitika zazikulu, amatha kugwira ntchito kapena kulephera. Mtengo, nthawi, ndi kutayika kwa kupanga komwe kumakhudzana ndi kukonza pampu yowonongeka kumaposa kwambiri kukhudzidwa kochepa pa liwiro la kupopa komwe kumachitika chifukwa cha fyuluta yosankhidwa bwino.
Chifukwa chake, ogwiritsa ntchito sayenera kupewa kuyikafyulutachifukwa choopa kuchepa kwa liwiro lopopera. Chinsinsi chili mukusankha kusalala koyenera kwa kuseferakutengera mtundu wa fumbi, kuchuluka kwa fumbi, ndi zofunikira za pampu yotulutsa mpweya. Kuphatikiza apo, kukonza nthawi zonse - monga kuyang'anira kuthamanga kosiyana ndi kuyeretsa kapena kusintha zinthu zosefera zotsekeka - ndikofunikira kuti fyuluta ikhale bwino. Mphamvu ya fyuluta pa liwiro la kupopa ndi yovomerezeka komanso yotheka, pomwe kuteteza pampu yotulutsa mpweya ndikofunikira kwa nthawi yayitali. Pakati pa ziwirizi, kukhazikitsa fyuluta ndiye chisankho chanzeru komanso chotsika mtengo.
