Pompu yanu imataya mphamvu yake, zomwe zimakukakamizani kuti mudzazenso chingwe chokoka madzi mobwerezabwereza. Izi zimawononga nthawi, zimaika pachiwopsezo moto wa pompu kuzima, komanso zimaletsa kuyenda kwa madzi ofunikira.

A Valavu ya phazi la PVCndi mtundu wa valavu yoyezera yophatikizidwa ndi chotsukira, chomwe chimayikidwa pansi penipeni pa chingwe chokokera madzi cha pampu. Ntchito yake ndikusunga madzi mu chitoliro, kusunga pampu yokonzekera, ndikutseka zinyalala.

Ndikukumbukira kukambirana ndi Budi za ntchito yaikulu yothirira yomwe kasitomala wake ankapereka. Ankakumana ndi mavuto nthawi zonse ndi mapampu awo. Mapampuwo ankayikidwa pamwamba pa matanki amadzi, ndipo m'mawa uliwonse ogwira ntchito ankafunika kuthera nthawi yambiri akumawakonzanso. Tinazindikira vuto mwachangu: sankagwiritsa ntchitomavavu a mapaziNdi gawo laling'ono komanso lotsika mtengo, koma ntchito yake m'dongosololi ndi yayikulu. Kufotokoza momwe valavu yosavuta iyi imathetsera vuto lokhumudwitsa komanso lokwera mtengo ndi chitsanzo chabwino kwambiri cha momwe gawo loyenera limapangira kusiyana konse.

Kodi kugwiritsa ntchito ma valve a mapazi a PVC ndi kotani?

Mukukonza pompu yotungira madzi kuchokera pachitsime, thanki, kapena dziwe. Koma kodi mungatani kuti madzi asatuluke ndikusunga mchenga kapena masamba akuwononga pa pompu yanu?

Ma valve a mapazi a PVC amagwiritsidwa ntchito kumapeto kwa mzere wokokera madzi pa pampu iliyonse yomwe siili m'madzi. Amachita ntchito ziwiri zofunika kwambiri: kusunga pampu yoyambira ndi kusefa madzi asanalowe mu dongosolo.

Tiyeni tikambirane njira ziwirizi, chifukwa zonse ndi zofunika kwambiri pamakina abwino opopera madzi. Choyamba ndi kupopera madzi. Mapampu ambiri, monga mapampu a centrifugal, ndi abwino kwambiri posuntha madzi koma ndi oipa kwambiri posuntha mpweya. Amafunika madzi olimba mu chitoliro chokoka madzi kuti agwire ntchito. Pampu ikasiya kugwira ntchito, mphamvu yokoka imafuna kukoka madzi onsewo m'chitsime kapena mu thanki. Valavu ya phazi imagwira ntchito ngati chotenthetsera madzi.chitseko cholowera mbali imodziMadzi akhoza kukokedwa, koma sangatulukenso. Izi zimapangitsa kuti paipi ikhale yodzaza ndipo pampu "ikhale yokonzeka" kugwira ntchito. Chachiwiri ndikusefaChotchingira, kapena chotsukira, chomwe chili kunja kwa valavu ndiye mzere woyamba wodzitetezera. Chimaletsa masamba, miyala, nsomba, ndi zinyalala zina zazikulu kuti zisalowe mu chitoliro. Izi zimaletsa zinyalalazo kuti zisatseke chitoliro cha pampu, zomwe zingayambitse kutha kapena kulephera kwathunthu.

Kugwiritsa Ntchito Kawirikawiri kwa Ma Valves a Mapazi a PVC

Kugwiritsa ntchito	Chifukwa Chake Chikufunika
Machitidwe a Madzi a Zitsime	Zimathandiza kuti pampu ikhale yolimba komanso kuti mchenga usalowe.
kuthirira	Zimaletsa kutayika kwa madzi oyambira komanso zimaletsa udzu/zinyalala kuti zisatseke ma sprinkler.
Maiwe ndi Nyanja	Amasefa zamoyo zam'madzi ndi matope, ndipo amasunga mawonekedwe abwino.
Maenje a Sump	Kuonetsetsa kuti pampu ya sump ili yokonzeka kugwira ntchito nthawi yomweyo ikafunika.
Matanki a Madzi	Imasunga chitoliro cha madzi chomwe chimakoka madzi kuti chigawidwe.

Kodi cholinga cha valavu ya phazi n'chiyani?

Mukudziwa kuti mukufunika valavu ya phazi, koma simukumvetsa bwino momwe imagwirira ntchito. Popanda kumvetsetsa "chifukwa chake," zimakhala zovuta kufotokoza kufunika kwake kapena kuthetsa vuto la makina olakwika bwino.

Cholinga chachikulu cha valavu ya phazi ndikusunga chitoliro cha pampu. Chimakwaniritsa izi mwa kugwira ntchito ngati valavu yowunikira yomwe imalola kuyenda mbali imodzi yokha—kulowa mu chitoliro, osati kutulukamo.

Ganizirani izi ngati mlonda wa pachipata pansi pa chitoliro chanu chokoka madzi. Pakati pa valavu iliyonse ya phazi ndivalavu yoyezeramakina. Mkati mwa ma valve athu a Pntek, muli kachidutswa kakang'ono kapena mpira, komwe nthawi zambiri kumakhala ndi kasupe. Pampu ikayaka, imapanga mphamvu yokoka. Mphamvu yokoka iyi imakhala yokwanira kukoka chidutswacho kutsegula, zomwe zimapangitsa kuti madzi azitha kulowa mu chitoliro. Madziwo amatsikira ku pampu ndikutuluka kupita ku dongosolo lanu. Pampu ikazima, mphamvu yokoka imatha. Tsopano, kulemera kwa mzati wonse wa madzi mu chitoliro kumabwerera pansi pa chitolirocho. Kupanikizika kumeneku, kuphatikiza ndi kasupe, kumatseka chitolirocho nthawi yomweyo. Izi zimatseka madzi mu chitolirocho. Ntchito yosavuta iyi ndi cholinga chonse: kuonetsetsa kuti mukayambanso kuyambiranso pampu, madzi ake amakhala okonzeka kutuluka, zomwe zimalepheretsa kuti asaume.

Ndi chiyani chabwino, ma valve a mkuwa kapena PVC foot?

Mukuwona ma valve onse a mkuwa ndi PVC omwe alipo. Muyenera kudziwa chomwe mungakulangizeni, chifukwa kusankha zinthu zolakwika kungayambitse dzimbiri, kuipitsidwa, kapena ndalama zina zosafunikira kwa makasitomala anu.

Palibe chilichonse mwa izi chomwe chili chabwino kuposa china chilichonse; chisankho chabwino kwambiri chimadalira momwe chimagwiritsidwira ntchito. PVC ndi yabwino kwambiri polimbana ndi dzimbiri, kuyanjana ndi mankhwala, komanso mtengo wake. Mkuwa ndi wabwino kwambiri pogwiritsidwa ntchito pamavuto amphamvu komanso pamavuto omwe amafuna kulimba kwambiri.

Funso limene ndimakambirana ndi Budi nthawi zambiri chifukwa makasitomala ake amakumana ndi mavuto osiyanasiyana. Kwa makasitomala ake ambiri pankhani ya ulimi, ulimi wa m'madzi, kapena kusamutsa madzi ambiri, nthawi zonse ndimalimbikitsa PVC. Chifukwa chake n'chosavuta: dzimbiri. Madzi ku Indonesia, makamaka madzi apansi panthaka, amatha kukhala ndi mchere womwe umawononga zitsulo pakapita nthawi. Mkuwa ukhoza kuwononga pang'onopang'ono kapena kuvutika ndi kuchotsedwa kwa zinki, kenako nkulephera. PVC ndi pulasitiki, kotero siigonjetsedwa ndi dzimbiri ndi dzimbiri. Idzakhala nthawi yayitali m'malo awa. Ndi yopepuka kwambiri komanso yotsika mtengo. Komabe, ngati kasitomala akukumana ndi kupsinjika kwakukulu kapena pamalo pomwe valavu ingagundidwe kapena kukanda ndi miyala (monga mumtsinje wothamanga), ndiye kuti kulimba kwa mkuwa kungakhale chisankho chabwino. Koma pafupifupi 90% ya ntchito zopopera madzi wamba, PVC imapereka phindu labwino kwambiri komanso moyo wautali wautumiki.

Ma Valves a PVC vs. Brass Foot

Mbali	Valavu ya Phazi la PVC	Vavu ya Mkuwa ya Phazi
Kukana Kudzikundikira	Zabwino kwambiri	Zabwino, koma zimatha kuwonongeka
Mtengo	Zochepa	Pamwamba
Kulemera	Zopepuka kwambiri	Zolemera
Kukana Mankhwala	Zabwino kwambiri	Wosauka
Kuyeza kwa Kupanikizika	Yabwino kugwiritsa ntchito mwachizolowezi	Zabwino kwambiri pa kuthamanga kwa magazi
Zabwino Kwambiri	Zitsime, ulimi wothirira, matanki, maiwe	Kugwiritsa ntchito mafakitale mokakamiza kwambiri

Kodi pampu ingagwire ntchito popanda valavu ya phazi?

Muli ndi kasitomala amene akufuna kuchepetsa ndalama ndipo akufunsani ngati angangosiya valavu ya phazi. Muyenera kuwapatsa yankho lomveka bwino lokhudza zoopsa zomwe zingachitike pa chisankhochi.

Inde, pampu ya centrifugal imatha kugwira ntchito popanda valavu ya phazi, koma ndi lingaliro loipa kwambiri. Imataya mphamvu yake nthawi iliyonse ikazima, zomwe zimafuna kukonzedwanso ndi manja nthawi zonse komanso kuwononga kwambiri pampu.

Ndingauze kasitomala uyu kuti kuyesa kusunga ndalama zochepa pa valavu ya phazi kungawawonongere ndalama zambirimbiri pa pompo yatsopano. Izi ndi zomwe zimachitika popanda valavu ya phazi. Pampu imayenda, kenako imayima. Madzi onse omwe ali mu chitoliro chokoka madzi nthawi yomweyo amabwerera m'chitsime. Nthawi ina mukatsegula pompo, pompo imakhala yodzaza ndi mpweya. Impeller ya pompo imangozungulira, osatha kupanga kukoka madzi. Izi zimatchedwa "kuuma." Madzi omwe amayenda mu pompo si chinthu chokha; komanso ndi choziziritsira komanso mafuta a zisindikizo za pompo. Pampu ikauma, zisindikizo zimatentha kwambiri mwachangu. Zitha kusungunuka kapena kusweka mumphindi yosakwana imodzi, zomwe zimapangitsa kuwonongeka kosatha ndi kutuluka madzi. Njira yokhayo yoti zigwirenso ntchito ndikutsanulira madzi pamanja mu chingwe chokoka madzi mpaka zitadzaza. Kuchita izi nthawi iliyonse ndi vuto lalikulu lomwe limalepheretsa kwathunthu cholinga cha makina opopa madzi okha.
