Ipayipi lensimbi elithambileuhlobo lwepayipi olusetshenziswa kabanziesetshenziswa ekuhlinzekweni kwamanzi, ekukhipheni amanzi, ekudlulisweni kwegesi nakwezinye izinkambu. Inezici zamandla aphezulu, ukumelana nokugqwala kanye nokuphila isikhathi eside. Ububanzi bepayipi lensimbi elithambile le-DINSEN bunguDN80～DN2600 (ububanzi obungu-80mm～2600mm),ngokuvamile amamitha ayi-6 futhi ingenziwa ngezifiso.Izinga lokucindezela: ngokuvamile lihlukaniswe ngohlobo lwe-T (ukucindezela okuphansi), uhlobo lwe-K (ukucindezela okuphakathi) kanye nohlobo lwe-P (ukucindezela okuphezulu).Chofoza ukuze uthole ikhathalogi yamapayipi ensimbi athambile.
Ngezindlela zokuxhuma zesistimu yamapayipi ensimbi athambile, i-DINSEN izifingqa kanje:
1.Ukuxhumeka kwesokhethi yohlobo lwe-T:Kuyisixhumi esiguquguqukayo, esibizwa nangokuthi isixhumi esingena ngaphakathi, okuyi-interface evamile yamapayipi ensimbi athambile asekhaya. Ingcindezi yokuxhumana phakathi kwendandatho yerabha kanye nesokhethi kanye ne-spigot yakha uphawu loketshezi. Isakhiwo sesokhethi sicabangela indawo kanye ne-engeli yokuphambuka kwendandatho yerabha, singazivumelanisa nesisekelo esithile, sinokumelana okuthile nokuzamazama komhlaba, sinezici zesakhiwo esilula,ukufakwa okulula nokuvalwa okuhle, njll. Amapayipi amaningi ensimbi asebenzisa amanzi emakethe asebenzisa lesi sixhumi esibonakalayo.
Izinyathelo ezithile: 1. Hlanza isokhethi kanye ne-spigot. 2. Faka i-lubricant odongeni lwangaphandle lwe-spigot kanye nodonga lwangaphakathi lwesokhethi. 3. Faka i-spigot kusokhethi ukuqinisekisa ukuthi isendaweni yayo. 4. Vala ngendandatho yerabha.
2. Ukuxhumeka kwesokhethi okuzibambela:Yamukela isakhiwo sokuvala isixhumi sohlobo lwe-T, esisetshenziswa ezimweni lapho ukuphonswa kwamanzi ekugobeni kwepayipi kukhulu kakhulu, noma indawo yokuhlala inkulu kakhulu, okwenza kalula isixhumi sokuxhuma siwele. Uma kuqhathaniswa nesixhumi sohlobo lwe-T, indandatho yokushisela, indandatho yokugcina ukuvulwa okushukumayo, i-flange ekhethekile yokucindezela kanye nama-bolt okuxhuma ashiselwe ekugcineni kwe-spigot yepayipi kuyangezwa ukwenza isixhumi sokuxhuma sibe nekhono elingcono lokulwa nokudonsa. Indandatho yokugcina kanye ne-flange yokucindezela kungashelela, ukuze isixhumi sokuxhuma sibe nekhono elithile lokunwebeka kanye nokuphambuka, elingasetshenziswa lapho i-pier ingakwazi ukusethwa.
3.Ukuxhumeka kwe-Flange:Ngokuqinisa amabhawodi okuxhuma, i-flange icindezela indandatho yokuvala ukuze kufezwe ukuvalwa kwe-interface, okuyi-interface eqinile. Ngokuvamile kuba njaloesetshenziswa ngezikhathi ezikhethekile njengokuxhumeka kwezesekeli zama-valve kanye nokuxhumeka kwamapayipi ahlukenes. Izinzuzo ukuthembeka okuphezulu kanye nokuvala okuhle. Ifanele izimo lapho ububanzi bepayipi bukhulu khona noma ubude bepayipi bude, futhi ifaneleka nasezindaweni lapho ukuxhumeka kwepayipi kanye nezidingo zokuliqaqa zivame khona. Kodwa-ke, uma ligqitshwe ngqo, kunengozi yokugqwala kuma-bolts, futhi ukusebenza ngesandla kunomthelela omkhulu emphumeleni wokuvala.
Izinyathelo ezithile: 1. Faka ama-flange kuzo zombili izinhlangothi zepayipi. 2. Faka i-gasket yokuvala phakathi kwama-flange amabili. 3. Bopha i-flange ngamabholithi.
4. Ukushisela i-arc:Izinduku zokushisela ezifanele njengezintambo zokushisela ze-MG289 zingakhethwa ukuze zishiselwe, futhi amandla aphezulu kunensimbi ephonswe ngensimbi. Uma usebenzisa ukushisela okushisayo kwe-arc, shisa kusengaphambili i-500-700℃ngaphambi kokushisela; uma kukhethwa induku yokushisela esekelwe ku-nickel ene-plasticity enhle kanye nokumelana nokuqhekeka okuphezulu, ukushisela okubandayo kwe-arc nakho kungasetshenziswa, okunomkhiqizo ophezulu, kodwa ukushisela okubandayo kwe-arc kunesivinini sokupholisa esisheshayo, futhi ukushisela kuthambekele ekwakhiweni komlomo omhlophe kanye nokuqhekeka.
5. Ukushisela igesi:Sebenzisa intambo yokushisela yohlobo lwe-RZCQ, njengentambo yokushisela yensimbi equkethe i-magnesium, sebenzisa ilangabi elingathathi hlangothi noma ilangabi elibuthakathaka le-carburizing, bese upholisa kancane kancane ngemva kokushisela.
Izinyathelo ezithile: 1. Hlanza ukuphela kwepayipi. 2. Qondanisa ukuphela kwepayipi bese ushibiliza. 3. Hlola ikhwalithi yeshibiliza.
6. Uxhumano olunezintambo:Ipayipi lensimbi elithambile elinezintambo kolunye uhlangothi lixhunywe esihlanganisini esinezintambo ezifanayo.Ifanele ukusetshenziswa okunobubanzi obuncane kanye nokucindezela okuphansi.Kulula kakhulu ukuyifaka nokuyiqaqa, kodwa ukusebenza kwayo kokuvala kulinganiselwe, futhi inezidingo eziphezulu zokunemba kokucubungula intambo kanye nemisebenzi yokufaka.
Izinyathelo ezithile zezinye izindlela zokuxhuma: 1. Cubungula izintambo zangaphandle ekugcineni kwepayipi. 2. Sebenzisa izixhumanisi zangaphakathi zezintambo ukuxhuma. 3.Vala nge-sealant noma i-tape eluhlaza.
7.Ukuxhumeka kwendandatho yokubopha enwebekayo: Faka indandatho yokuvala enwebekayo ekugcineni kwengxenye ngayinye yepayipi, bese ucindezela izingxenye ezimbili zepayipi bese uzixhumanisa ndawonye ngesixhumi sokusunduza. Indandatho yokuvala iqinisekisa ukusebenza kokuvala kokuxhumeka kanyekufanelekile kumapayipi anobubanzi obuncane.
8.Ukuxhumeka kwendandatho yephiko elingangeni manzi okuqinile:Shintshela indandatho yephiko lokumisa amanzi epayipini lensimbi eliyi-ductile, bese uliphonsa ngqo libe yingcezu eyodwa ngesikhathi sokwakha izindonga zekhonkrithi eziqinisiwe. Ngokuvamile lisetshenziselwa ukuxhuma amapayipi ensimbi ayisi-ductile ukuze kukhishwe amanzi ezindongeni ezifana nemithombo yokuhlola.
Ngamafuphi, indlela yokuxhuma yamapayipi ensimbi athambile ingakhethwa ngokuya ngesimo sokwakhiwa. Ngokukhethekile,uxhumano lwesokhethi lufanele amapayipi angaphansi komhlaba, uxhumano lweflange lufanele izikhathi ezidinga ukuhlukaniswa njalo, uxhumano olunezintambo lufanele amapayipi anobubanzi obuncane, uxhumano lokushisela lufanele izindawo ezinomfutho ophezulu kanye nezinokushisa okuphezulu, kanti uxhumano lwemishini lufanele izimo zesikhashana noma eziphuthumayo.
