Iivalvu Eziyilwe Ngoomatshini: Inzuzo Esebenzayo Kwicandelo Leoyile Negesi LaseMntla Melika
Kwintsimi, ukuthembeka kubaluleke ngaphezu kwayo nayiphi na enye into. Oko kuyinyani ngakumbi kwizicelo zeoyile negesi kulo lonke elaseMntla Melika, apho iivalvu zichatshazelwa kuxinzelelo oluphezulu, ulwelo olubolayo, kunye nokujikeleza kobushushu imihla ngemihla. Phakathi kwezinto ezininzi ezisebenzayo, umzimba wevalvu eyenziweyo ufumene udumo ngokuqina kunye nobomi obude benkonzo.
Amandla Onokuthembela Kuwo
Ngokungafaniyo nee-castings, imizimba yeevalvu ezenziwe ngobumba yenziwa ngamandla okucinezela, atshintsha ulwakhiwo lwentsimbi kwaye aphucule ukuthembeka kwayo koomatshini. Isiphumo siyinxalenye eqinileyo, enamandla kunye neziphene ezimbalwa zangaphakathi. Kwizicelo zokwenyani—nokuba ngumgca wokuhambisa igesi e-Alberta okanye iyunithi yokucubungula eTexas—lo mahluko kumgangatho wezinto ezibonakalayo uguqulela ekuvuzeni nasekungaphumelelini okuncinci.
Iinkqubo zoxinzelelo oluphezulu, ingakumbi ezo zisebenza kwi-6,000 psi nangaphezulu, zifuna izinto ezingayi kuqhekeka xa zilayishwa ngokuphindaphindiweyo. Iivalvu zentsimbi ezenziwe ngomatshini zisingatha ezi meko ngomngcipheko omncinci wokudinwa, nto leyo ezenza zilungele ukusetyenzwa kwii-separators, ii-compressors, kunye neevalvu zolawulo oluhamba ngesantya esiphezulu.
Ukuxhathisa ukugqwala, ityuwa, kunye noxinzelelo
Izixhobo zombane ezikwiGulf of Mexico zijongene nokufuma okuphezulu nomoya ogcwele ityuwa. Izixhobo ezikwilwandle zihlala ziphatha igesi emuncu kunye nolwelo olubolayo. Nokuba yeyiphi na indlela, iivalvu kufuneka zihlale ziqinile. Imizimba eyenziwe ngentsimbi engagqwaliyo okanye i-alloy efana ne-A182 F316 kunye ne-F51 inika ukumelana okungcono kokugqwala kunezixhobo eziqhelekileyo.
Oku akuyonto nje yokuqina—kungokunciphisa iindleko zokulungisa zizonke. Umzimba wevalvu omelana nokugqwala kwemingxuma kunye nemingxunya uya kuhlala iminyaka emininzi ebaleni ngaphandle kokufuna ukutshintshwa. Oko kunempembelelo elinganisekayo kwixesha lokungasebenzi kunye neshedyuli yomsebenzi.
Ukuchaneka koomatshini = Ukulingana ngcono, Ukuhamba ngcono
Enye inzuzo edla ngokungananzwa yezixhobo ezibunjiweyo kukusebenza kwazo ngendlela efanayo. Ngenxa yokuba isinyithi sifana ngakumbi, abavelisi banokufikelela ekunyamezeleni okuqinileyo. Isiphumo kukuba iindawo zokutywina zilungelelaniswe ngcono kwaye iindlela zokuhamba zihambe kakuhle. Kubasebenzisi bokugqibela, oko kuthetha ukuba iingxaki zokutywina azikho, ukufakwa lula, kunye nokusebenza ngcono kwexesha elide.
Iinjineli kunye nee-OEM eMntla Melika ezichaza izinto zevalvu ezenziwe ngomatshini ochanekileyo zixela amazinga aphantsi okulahlwa kunye nokuhlanganiswa okubushelelezi ngexesha lokuhlanganiswa kwevalvu. Ingakumbi xa kusetyenzwa kwiinkcukacha ze-API 602, ASME B16.34, okanye ze-NACE MR0175, yonke inkcukacha ibalulekile.
Ukuhambelana okuqinisekisiweyo kweCandelo loNikezelo
Esinye isizathu sokuba ii-valve bodies ezenziwe ngobuqili zikhethwe kwiiprojekthi zaseMntla Melika ngamaxwebhu. Ababoneleli abadumileyo babonelela ngokulandelela ubushushu, iingxelo zovavanyo lwezinto ezibonakalayo, kunye namaxwebhu okuthobela umthetho kwi-lot nganye. Olu landelelwano alupheleli nje kwimithetho—ludla ngokufunwa ngabaqhubi xa besebenza kunye nokuhlolwa.
Njengoko iinkampani ezininzi zase-US naseKhanada ngoku zikhetha ukufumana imveliso yengingqi, izixhobo ezenziwe ngobuqili zibonelela ngenzuzo yochungechunge lokubonelela ngempahla. Amaxesha okukhokela amfutshane, uthutho lwezinto lunokuqikelelwa ngakumbi, kwaye unxibelelwano lulula xa usebenza namaqabane anamava aqondayo iikhowudi zoshishino lwasekuhlaleni.
Ukusebenza Okwenyani, Kungekuko nje Iinkcazo zePhepha
Ukukhethwa kwe-forged over cast akuyonto ithethwayo. Idatha yasentsimini ibonise ukuba imizimba yevalvu yentsimbi edibeneyo ihlala ixesha elide kwinkonzo yoxinzelelo oluphezulu. Amaqela okulungisa ekuye kwafuneka atshintshe i-castings eqhekekileyo phakathi komjikelo awadingi ukweyiseka. Iindawo ezidibeneyo zihambelana ngakumbi, zithembekile ngakumbi, kwaye zifanelekile ngakumbi kulindelo oluguqukayo lweziseko zeoyile negesi zanamhlanje.
Okukwintsusa
Ukuba wakha okanye ugcina iivalvu zeenkqubo ezisezantsi, eziphakathi, okanye ezisezantsi eMntla Melika, ukukhetha umzimba wevalvu eyenziwe ngomgunyathi akuyonto nje ifunekayo—lutyalo-mali olukrelekrele. Imalunga nokuphepha ukusilela, ukunciphisa amaxesha okulungisa, kunye nokubonelela ngoxolo lwengqondo kubaqhubi kunye nee-EPC ngokufanayo.
