1. Kodi Ductile Iron ndi chiyani?
Chitsulo chopangidwa ndi ductile ndi mtundu wa chitsulo chomwe chili ndi mphamvu komanso kusinthasintha kowonjezereka poyerekeza ndi chitsulo chachikhalidwe. Izi zimachitika powonjezera zinthu zochepa monga magnesium ku chitsulo panthawi yosungunula. Zotsatira zake zimakhala zinthu zomwe zimatha kupirira kupsinjika kwakukulu popanda kusweka, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pomwe kukana kugwedezeka ndikofunikira.
2. Kodi Chitsulo Chopangidwa ndi Nsalu N'chiyani?
Koma chitsulo chopangidwa ndi chitsulo, kaboni, ndi silikoni ndi chinthu chopangidwa ndi chitsulo chosungunuka. Kawirikawiri, chimakhala chofooka kwambiri kuposa chitsulo chosungunuka ndipo chimadziwika ndi makhalidwe ake abwino kwambiri opangidwa ndi chitsulo komanso kukana kuwonongeka. Komabe, sichili ndi mphamvu yofanana, zomwe zingayambitse ming'alu ikakhudzidwa kwambiri kapena ikagundidwa.
3. Kodi pali kusiyana kotani pakati pa ma valve achitsulo opangidwa ndi ductile ndi ma valve achitsulo opangidwa ndi cast iron?
Kusiyana pakati pa ma valve achitsulo chosungunuka ndi ma valve achitsulo chosungunuka n'kofunikira kwambiri. Nazi mfundo zofunika kuziganizira:
Mphamvu ndi Kusinthasintha:Ma valve achitsulo opangidwa ndi ductile ali ndi mphamvu zambiri komanso kusinthasintha chifukwa cha njira yawo yopangira. Izi zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito ndi mphamvu yamagetsi komanso madera omwe ali ndi katundu wosinthasintha.
Kukana Kudzikundikira:Chitsulo chopangidwa ndi ductile chimakhala ndi mphamvu yolimbana ndi dzimbiri ngati chaphimbidwa bwino. Chitsulo chopangidwa ndi pulasitiki chimakhala chosavuta kugwidwa ndi dzimbiri, zomwe zingafupikitse moyo wake, makamaka m'malo onyowa kapena chinyezi.
Kulemera:Ma valve achitsulo chosungunuka nthawi zambiri amakhala opepuka kuposa ma valve achitsulo chosungunuka omwe ali ndi kukula kofanana. Izi zingathandize kuyika mosavuta ndikuchepetsa ndalama zotumizira kwa opanga.
Mtengo:Kawirikawiri, ma valve achitsulo opangidwa ndi ductile amakhala okwera mtengo kwambiri chifukwa cha zinthu zake zabwino. Komabe, kulimba kwake kungapangitse kuti azigwiritsidwa ntchito bwino pakapita nthawi.
Mapulogalamu:Ma valve achitsulo chosungunuka nthawi zambiri amagwiritsidwa ntchito m'maboma ndi m'mafakitale, pomwe ma valve achitsulo chosungunuka amagwiritsidwa ntchito bwino m'maboma omwe ali ndi mphamvu zochepa komanso m'maboma amkati.
4. Kodi muyenera kusankha chiyani: Ma Vavu achitsulo chosungunuka kapena Ma Vavu achitsulo chosungunuka?
Kusankha pakati pa mavavu achitsulo choponderezedwa ndi chitsulo choponderezedwa kumadalira kwambiri zosowa zanu. Ngati mukufuna valavu yomwe imatha kuthana ndi kuthamanga kwambiri komanso kukana kugunda, chitsulo choponderezedwa ndi chitsulo ndiye njira yabwino kwambiri. Pamagwiritsidwe ntchito omwe mtengo wake ndi waukulu ndipo kufunikira kwake kuli kochepa, chitsulo choponderezedwa chingakhale chokwanira.
5. Ndi chitsulo chiti chomwe chili chotsika mtengo, chitsulo chosungunuka kapena chitsulo chosungunuka?
Chitsulo chopangidwa nthawi zambiri chimakhala chotsika mtengo kuposa chitsulo chopangidwa ndi ductile pansi pa ntchito yanthawi zonse. Izi zimachitika makamaka chifukwa njira yopangira chitsulo chopangidwa ndi ductile ndi yokhwima komanso yosavuta, palibe chifukwa chowonjezera zinthu zomangira ma nodular (monga magnesium) kuti zigwiritsidwe ntchito ngati spheroidizing, ndipo mtengo wa zinthu zopangira ndi mtengo wopanga ndi wotsika. Komabe, chuma ichi chimabwera chifukwa cha mphamvu, kulimba, ndi kukana kugwedezeka—chitsulo chopangidwa ndi ductile ndi chofooka ndipo chili ndi mphamvu yochepa. Mosiyana ndi zimenezi, ngakhale ductile iron ndi yokwera mtengo pa unit iliyonse, mphamvu yake yayikulu komanso kukana bwino ming'alu kumatanthauza kuti ikhoza kupangidwa ndi makulidwe opyapyala a khoma ndipo nthawi zina imachepetsa kulemera konse. Kuchokera pamalingaliro a moyo wonse, ma valve achitsulo chopangidwa ndi ductile nthawi zambiri amatha kuchepetsa ndalama zokonzanso ndi kusintha pambuyo pake chifukwa cha chitetezo chawo chapamwamba, kudalirika, komanso moyo wautali wautumiki. Chifukwa chake, chisankhocho chiyenera kuyeza mtengo wogula kwakanthawi kochepa komanso ubwino wogwiritsa ntchito kwa nthawi yayitali: pazochitika zosafunikira kwambiri ndi kupanikizika kokhazikika komanso mikhalidwe yofatsa yogwirira ntchito, chitsulo chopangidwa ndi ductile mosakayikira ndi chisankho chotsika mtengo kwambiri; pomwe pazochitika zokhala ndi kupanikizika kwakukulu, kugwedezeka, kapena chitetezo, ndalama zowonjezera zoyambira mu ductile iron ndizoyenera ndalamazo.
6. Mapeto
TWSndi kampani yodziwika bwino ya ma valve ku Tianjin. Mzere wake wa malonda umaphimbamavavu a gulugufe, mavavu a chipata, ma valve owunikira, ndi zina zotero. Posankha valavu, ngati mikhalidwe yogwirira ntchito ndi yayikulu ndipo zofunikira pakukana ming'alu ndi zapamwamba, mavalavu achitsulo opangidwa ndi TWS amatha kusankhidwa; ngati mikhalidwe yogwirira ntchito ndi yofatsa komanso bajeti yake ndi yochepa, mavalavu ake achitsulo chopangidwa ndi chitsulo ndi otsika mtengo.
