Ndi kupita patsogolo kwaukadaulo waku China, mavavu opangidwa ndi ChemChina agwiritsidwanso ntchito mwachangu, omwe amatha kumaliza kuwongolera kolondola, kuthamanga, kuchuluka kwamadzi ndi kutentha.M'makina owongolera opangira mankhwala, valavu yoyang'anira ndi ya chachikulu The actuator, chitsanzo chake ndi mtundu wa chipangizocho zimakhudza kwambiri kukhazikika kwa dera lowongolera.Ngati kusankha ndi kugwiritsa ntchito valavu yoyang'anira sikuli koyenera, kudzawopseza kwambiri moyo wautumiki wa valve yoyendetsa, ndipo ngakhale mkhalidwewo uli wovuta, ungayambitsenso dongosololi kuti libweretse mavuto oimika magalimoto..Ndi chitukuko cha makina opanga mafakitale, valavu yowongolera pneumatic imagwiritsidwanso ntchito kwambiri ngati chowongolera chodziwika bwino.Valavu yamtunduwu imakhala ndi mawonekedwe odalirika komanso mawonekedwe osavuta.Lili ndi tanthauzo lofunika kwambiri poonetsetsa chitetezo cha dongosolo.Zotsatirazi Kusanthula mozama pa kusankha ndi kugwiritsa ntchito ma valve olamulira pneumatic panthawi ya mankhwala odzipangira okha.
1. Kusankhidwa kwa valavu ya pneumatic control control 1. Kusankhidwa kwa mtundu wa valve yolamulira ndi kapangidwe kake kumachokera ku kusiyana kwa kupweteka kwake.Mpweya wowongolera ma valve ukhoza kugawidwa m'mitundu iwiri yosiyana, yomwe ndi sitiroko yowongoka ndi sitiroko ya angular, molingana ndi kapangidwe kake Potengera mfundo, ma valve owongolera ma pneumatic amatha kugawidwa m'mavavu agulugufe, ma valve aang'ono, ma valve a manja, ma valve a mpira, ma valve a diaphragm, ndi mavavu olunjika-kupyolera pampando umodzi.Pakalipano, valavu yowongoka yokhala ndi mpando umodzi ndiyo valavu yoyendetsera yomwe ili ndi kutayikira kochepa kwambiri pakugwiritsa ntchito.Ntchito yothamanga ndi yabwino ndipo mapangidwe ake ndi osavuta.Ikhoza kugwiritsidwa ntchito m'madera omwe ali ndi zofunikira zowonongeka kwambiri, koma njira yake yothamanga imakhala yosokoneza, yomwe imakhala yoletsedwa pamlingo winawake.Kupititsa patsogolo kukula kwa ntchito yake.Valavu yowongoka yokhala ndi mipando iwiri ndiyosiyana ndi valavu yowongoka yokhala ndi mpando umodzi.Palibe okhwima kufunikira kwa kutayikira.Ndizoyenera kugwiritsidwa ntchito m'malo omwe ali ndi kusiyana kwakukulu kwapantchito.Tsopano, valve yowongoka yokhala ndi mipando iwiri ndiyomwe imagwiritsidwa ntchito kwambiri ku China.Mtundu wa valve yowongolera.Mavavu a manja amatha kugawidwa m'mitundu iwiri, mavavu a manja osindikizidwa kawiri ndi mavavu a manja osindikizidwa amodzi.Mavavu a manja ali ndi kukhazikika kwapadera, phokoso lochepa, ndi disassembly yabwino ndi kusonkhana.Komabe, mawu awo ndi okwera kwambiri ndipo zopempha zokonzanso zimakhalanso zapamwamba.Choncho, kukula kwa ntchito kumakhalanso ndi zovuta zina.Njira yoyendetsera valavu ya diaphragm ndi yosavuta, imapanganso ndikugwiritsa ntchito PT-FE ndi PFA yokhala ndi corrosion resistance resistance, yomwe ili yoyenera kwambiri kuti igwiritsidwe ntchito m'madera amphamvu a alkali kapena a asidi amphamvu, koma ntchito yowonongeka ndi yochepa kwambiri.2. Kusankhidwa kwa zida zopangira ma valve Kugwiritsira ntchito ma valve olamulira kumakhala ndi zofunikira zovuta kwambiri kuti musawononge dzimbiri, kuthamanga kwa kutentha ndi kutentha.Chifukwa chake, ma valve owongolera apano nthawi zambiri amagwiritsa ntchito zida zachitsulo zotayidwa, zomwe zimatha kusintha bwino kukana kwa dzimbiri kwa valavu yowongolera.Ndipo compressive mphamvu;zitsulo zosapanga dzimbiri zimagwiritsidwa ntchito kwambiri muzopangira zida zamkati za valve yolamulira.Ngati dongosololi lili ndi zofunikira zochepa zowonongeka, mukhoza kusankha zisindikizo zofewa.Ngati dongosololi lili ndi zofunika kwambiri pakutha, muyenera kugwiritsa ntchito Hastelloy .Posankha zipangizo zosagwira dzimbiri, m'pofunika kufotokoza mwachidule ndi kulingalira za ndende yamadzimadzi, kutentha ndi kupanikizika, ndi kupanga chisankho chokhudzana ndi mantha a makina.3. Mfundo yogwiritsira ntchito ndi ubwino wa valavu yoyendetsa pneumatic (1) Kusanthula kwa ndondomeko ya ntchito ya valavu yolamulira pneumatic The valve position ndi zigawo zina zimatha kukwaniritsa zotsatira za kuyendetsa valavu, ndipo zimathanso kumaliza kusintha kofanana kwa kusintha, ndiyeno gwiritsani ntchito zizindikiro zowongolera zosiyanasiyana kuti mutsirize kuyika kwa sing'anga kutentha kwa mapaipi, kuthamanga, kuthamanga ndi zina.Valavu yowongolera ma pneumatic ili ndi mawonekedwe oyankha mwachangu, kuwongolera kosavuta, ndi chitetezo chamkati, ndipo palibe chifukwa choyikira zida zoteteza kuphulika.Chipinda cha mpweya chikakhala ndi chizindikiro cha kupanikizika, nembanemba imawonetsa kukankhira, kukoka mbale yoponyera, tsinde la valve, ndodo yokankhira, kasupe wopondereza, ndi phata la valve kuti lisunthe.Pambuyo pakulekanitsidwa kwa valve pampando wa valve, mpweya woponderezedwa udzazungulira.Pambuyo pa kukakamizidwa kwa chizindikiro kufika pamtengo wina, valavu idzakhalabe pamtunda wofanana.Valavu yowongolera pneumatic imakhala yodalirika kwambiri, mawonekedwe osavuta, ndipo sidzawonetsa kuwala kwamagetsi pakugwira ntchito.Chifukwa chake, kuchuluka kwake komwe kumagwiritsidwa ntchito ndikwambiri, ndipo kumatha kugwiritsidwanso ntchito m'malo otumizira mafuta omwe ali ndi zofunikira zotsimikizira kuphulika.
2. Kusanthula kwa machitidwe othamanga a valve yolamulira Makhalidwe oyenda a valve olamulira akuphatikizapo kuyendetsa ntchito ndi kuyenda bwino.Pansi pa chikhalidwe chakuti kusiyana kwapakati pakati pa cholowera ndi chotulukira kumakhala kosalekeza, kutuluka kwa valve yoyanjanitsa ndiko kuyenda koyenera.Izi otaya bwino ali ndi mzere wolunjika, Parabola, mwamsanga kutsegula, kuchuluka makhalidwe.Pankhani yamakhalidwe abwino, njira yodziwongolera yokha yamankhwala imadalira mfundo ya chipukuta misozi popanga.Kupanga dongosolo kumakhala ndi malamulo okhwima pa makhalidwe a valve yolamulira.Malinga ndi chinthu ichi, posankha, m'pofunika kusanthula amplification factor of valve regulating.Pewani kusintha kwa coefficient.Ponena za mawonekedwe othamanga, valavu yolamulira idzawonetsa kusintha kwa kayendetsedwe ka kayendetsedwe ka ntchito, zomwe zimakhala zosavuta kuyambitsa mafunso ogwedezeka.Pamene ntchito yaikulu yotsegulira ikugwiritsidwa ntchito, valve yolamulira idzawoneka ngati ikuchedwa, ndipo n'zosavuta kusonyeza kuti kusintha sikuyenera nthawi yake ndipo kusintha sikumveka.Poganizira izi, valavu yoyendetsera kayendedwe ka mzere sayenera kugwiritsidwa ntchito mu dongosolo lokhala ndi kusintha kwakukulu.
3. Njira zodzitetezera poika valavu yoyang'anira Musanakhazikitse valavu yoyendetsera, valve yoyendetsa iyenera kufufuzidwa mosamala komanso mwachidziwitso.Paipiyo ikatsukidwa bwino, kuyikako kumatha kuchitika.Panthawi yoyikapo, ndikofunikira kusunga zowongoka kapena zowongoka.Panthawi imodzimodziyo, ndikofunikanso kukhazikitsa mabatani kutsogolo ndi kumbuyo kwa valve yolamulira kuti atsimikizire chitetezo ndi kukhazikika kwa ntchito yoyendetsa valve.Kuphatikiza apo, pakukhazikitsa, ndikofunikiranso kusanthula njira yoyendetsera.Pofuna kuonetsetsa kuti chipangizocho chili ndi ubwino wake, chipangizocho chiyenera kuikidwa pansi pazovuta zochepa.M'pofunikanso kuonetsetsa kuti kutalika kwa gawo la chitoliro chowongoka mu njira yolowera kulowera kumakwaniritsa zofunikira za ndondomekoyi.Ngati kuyikako kumafuna valavu yaing'ono ya m'mimba mwake, kumafunika kutsatira mosamalitsa ndondomeko zokonzekera.Nthawi zonse, gawo la chitoliro chowongoka panjira yotulutsira liyenera kukhala 3 mpaka 5 kuwirikiza kawiri kuposa m'mimba mwake.Pakuyika, ndikofunikira kusiya malo okwanira kuti athandizire chitetezo ndi ntchito yotsatira, ndikuwongolera kuchuluka kwa mapaipi.Posankha njira yolumikizira mapaipi, zinthu zosiyanasiyana zokopa ziyenera kufotokozedwa mwachidule ndikuwunikidwa.4. Pomaliza, valavu yolamulira ndiyo chigawo chachikulu cha mankhwala odzipangira okha.Kusankhidwa, chipangizo ndi chitetezo cha valve yolamulira chidzakhudza ntchito ya mankhwala.Chifukwa chake, wogwiritsa ntchitoyo ayenera kutsatira mosamalitsa malangizo a chipangizocho ndikufotokozera mwachidule Kusanthula mitundu yosiyanasiyana, nthawi zonse sankhani valavu yowongolera.Ndi chitukuko cha sayansi ndi ukadaulo, kuwongolera kwamankhwala kwadziwikiratu kwaperekanso zofunika kwambiri pakuwongolera ma valve.Izi zimafuna kufufuza mozama pa ma valve oyendetsa kuti apititse patsogolo kudalirika ndi kukhazikika kwa ma valve oyendetsa.
