Vavu ya Gulugufe Yapamwamba Kwambiri
✧ Kufotokozera
Vavu ya gulugufe yogwira ntchito bwino kwambiri ndi mtundu wa valavu yopangidwira ntchito zovuta zomwe zimafuna kutseka kodalirika, mphamvu yothamanga kwambiri, komanso kutsekedwa mwamphamvu. Mavavu amenewa amagwiritsidwa ntchito kwambiri m'mafakitale monga mafuta ndi gasi, kukonza mankhwala, kupanga magetsi, ndi kukonza madzi, pakati pa ena. Amadziwika ndi kuthekera kwawo kowongolera kuyenda bwino komanso kupirira zovuta pakugwira ntchito. Zina mwazinthu zofunika kwambiri za ma valve a gulugufe othamanga kwambiri ndi izi: Kutseka Molimba: Ma valve awa apangidwa kuti achepetse kutuluka kwa madzi ndikupereka chisindikizo chodalirika ngakhale m'malo opanikizika kwambiri kapena kutentha kwambiri. Kapangidwe Kolimba: Ma valve a gulugufe othamanga kwambiri nthawi zambiri amapangidwa ndi zinthu zolimba, monga chitsulo chosapanga dzimbiri kapena zitsulo zakunja, kuti azitha kuwononga kapena kuwononga. Kugwiritsa Ntchito Mphamvu Yochepa: Ma valve ambiri a gulugufe othamanga kwambiri amapangidwira kuti azigwira ntchito molimbika pang'ono, zomwe zimathandiza kuti zinthu zigwire bwino ntchito komanso kuchepetsa kuwonongeka kwa ma valve. Kapangidwe Kotetezeka Pamoto: Ma valve ena a gulugufe othamanga kwambiri amapangidwira kuti akwaniritse miyezo yotetezeka pamoto, kupereka chitetezo chowonjezera pakagwa moto. Kutha Kupanikizika Kwambiri: Ma valve awa ndi oyenera kugwiritsa ntchito omwe amafunikira mphamvu zogwirira ntchito molimbika kwambiri. Mukasankha valavu ya gulugufe yothamanga kwambiri, ndikofunikira kuganizira zinthu monga momwe imagwiritsidwira ntchito, momwe imagwiritsidwira ntchito, momwe zinthu zikuyenderana, miyezo yamakampani, ndi zinthu zachilengedwe. Kukula koyenera ndi kusankha ndikofunikira kwambiri kuti muwonetsetse kuti valavu ikukwaniritsa zofunikira pakugwira ntchito komwe mukufuna.
✧ Mbali za Valavu ya Gulugufe Yogwira Ntchito Kwambiri
Ma Vavu a Gulugufe Ogwira Ntchito Kwambiri ali ndi mipando ya polymer yokhala ndi moyo wopanda malire komanso kukana mankhwala ambiri - mankhwala ochepa amadziwika kuti amakhudza ma polima okhala ndi fluorocarbon, zomwe zimapangitsa kuti zinthuzi zikhale zokongola kwambiri pamavavu amafakitale. Ubwino wake umaposa wa ma polima a rabara kapena ena a fluorocarbon pankhani ya kupanikizika, kutentha ndi kukana kukalamba.
Kapangidwe ka valavu yonse
Tsinde la Vavu ya Butterfly ya High Performance sili pakati pa madera awiri. Chotsitsa choyamba chimachokera pakati pa valavu, ndipo chotsitsa chachiwiri chimachokera pakati pa chitoliro. Izi zimapangitsa kuti diski ichotsedwe kwathunthu ku diski pamtunda wochepa kwambiri kuchokera pa mpando. Onani chithunzi pansipa:
Kapangidwe ka mipando
Ponena za mpando, monga tafotokozera kale, valavu yophimbidwa ndi rabara imatsekedwa poyikira m'manja mwa rabara. Kapangidwe ka mpando wa Valuvu ya Gulugufe Yogwira Ntchito Kwambiri. Chithunzi chomwe chili pansipa chikufotokoza momwe mipando imakhudzidwira muzochitika zitatu:
Pambuyo pa msonkhano: pamene unasonkhanitsidwa popanda kupanikizika
Chikasonkhanitsidwa popanda kupanikizika, mpando umayendetsedwa ndi mbale ya gulugufe. Izi zimathandiza kutseka thovu kuchokera pamlingo wa vacuum mpaka kupanikizika kwakukulu kwa valavu.
Kupanikizika kwa Axial:
Mbiri ya mpando wa G imapanga chisindikizo cholimba pamene mbaleyo ikuyenda. Kapangidwe kake kamachepetsa kuyenda kwambiri kwa mpando.
Kupanikizika kumbali yolowera:
Kupanikizika kumatembenuza mpando kutsogolo, zomwe zimawonjezera mphamvu yotsekera. Kuyika m'malo opindika kumapangidwira kuti mpando uzizungulira. Iyi ndiyo njira yabwino kwambiri yokwezera.
Mpando wa Vavu ya Gulugufe Yogwira Ntchito Kwambiri uli ndi ntchito yokumbukira. Mpando umabwerera ku mawonekedwe ake oyambirira ukatha kukwezedwa. Kuthekera kwa mpando kuchira kumatanthauzidwa ndi kuyeza kusintha kosatha kwa mpando. Kusintha kosatha kotsika kumatanthauza kuti zinthuzo zimakhala ndi kukumbukira bwino - sizimasinthasintha kokhazikika pamene katundu akugwiritsidwa ntchito. Chifukwa chake, kuyeza kusintha kosatha kumatanthauza kuchira bwino kwa mpando komanso nthawi yayitali yoti chisindikizo chikhalepo. Izi zikutanthauza kutsekedwa bwino pansi pa kupanikizika ndi kutentha. Kusintha kumakhudzidwa ndi kutentha.
Kulongedza tsinde ndi kapangidwe ka zotengera
Mfundo yomaliza yofananira ndi chisindikizo chomwe chimaletsa kutuluka kwa madzi akunja kudzera m'dera la tsinde.
Monga mukuonera pansipa, ma valve okhala ndi rabala ali ndi chisindikizo chosavuta komanso chosasinthika cha tsinde. Kapangidwe kake kamagwiritsa ntchito chitseko cha tsinde pakati pa shaft ndi makapu awiri a rabala a U kuti amange cholumikiziracho kuti chisatuluke madzi.
Palibe kusintha komwe kumachitika pamalo otsekedwa, zomwe zikutanthauza kuti ngati patuluka madzi, valavu iyenera kuchotsedwa pamzere ndikukonzedwa kapena kusinthidwa. Malo otsika a shaft alibe chithandizo cha tsinde, kotero ngati tinthu tating'onoting'ono tisamukira ku malo apamwamba kapena otsika a shaft, mphamvu yoyendetsera imakwera, zomwe zimapangitsa kuti ntchito ikhale yovuta.
Ma Vavu a Gulugufe Ogwira Ntchito Kwambiri omwe awonetsedwa pansipa apangidwa ndi kulongedza kosinthika kwathunthu (shaft seal) kuti atsimikizire kuti ntchito yayitali komanso kuti palibe kutuluka kwa madzi akunja. Ngati kutuluka kwa madzi kwachitika pakapita nthawi, valavuyo imakhala ndi cholumikizira chosinthika kwathunthu. Ingotembenuzani mphete ya nati nthawi imodzi mpaka kutulukako kutayike.
✧ Ubwino wa Valavu ya Gulugufe Yogwira Ntchito Kwambiri
Pakutsegula ndi kutseka valavu yachitsulo chopangidwa ndi chitsulo, chifukwa kukangana pakati pa diski ndi pamwamba pa valavu kumakhala kochepa kuposa kwa valavu ya chipata, sikutha kusweka.
Kutsekeka kapena kutseka kwa tsinde la valavu ndi kochepa, ndipo kuli ndi ntchito yodalirika yodulira, ndipo chifukwa kusintha kwa doko la mpando wa valavu kumafanana ndi kutsekeka kwa diski ya valavu, ndikoyenera kwambiri kusintha kuchuluka kwa madzi. Chifukwa chake, valavu yamtunduwu ndi yoyenera kwambiri kudula kapena kulamulira ndi kugwedeza.

✧ Utumiki Wogulitsa Pambuyo Pogulitsa
Monga wopanga mavavu achitsulo opangidwa ndi akatswiri komanso wogulitsa kunja, tikulonjeza kupatsa makasitomala ntchito yabwino kwambiri yogulitsa pambuyo pogulitsa, kuphatikizapo izi:
1. Perekani malangizo ogwiritsira ntchito mankhwala ndi malingaliro osamalira.
2. Pa zovuta zomwe zachitika chifukwa cha mavuto a khalidwe la malonda, tikulonjeza kupereka chithandizo chaukadaulo ndi kuthetsa mavuto mkati mwa nthawi yochepa kwambiri.
3. Kupatula kuwonongeka komwe kumachitika chifukwa chogwiritsa ntchito bwino, timapereka ntchito zokonzanso ndi kusintha kwaulere.
4.Tikulonjeza kuyankha mwachangu zosowa za makasitomala panthawi ya chitsimikizo cha malonda.
5. Timapereka chithandizo chaukadaulo cha nthawi yayitali, upangiri pa intaneti ndi maphunziro. Cholinga chathu ndikupatsa makasitomala chithandizo chabwino kwambiri ndikupangitsa kuti zomwe makasitomala amakumana nazo zikhale zosangalatsa komanso zosavuta.
