Ipayipi le-iron ductileluhlobo lwempahla yepayipi kabanziesetshenziswa ekuphakeleni kwamanzi, emiseleni yamanzi, ekudluliselweni kwegesi neminye imikhakha. Inezici zamandla aphezulu, ukumelana nokugqwala kanye nempilo ende yesevisi. Ububanzi bobubanzi bepayipi lensimbi le-DINSEN ductileI-DN80～DN2600 (ububanzi 80mm～2600mm),ngokuvamile 6 amamitha futhi kungenziwa egcizelele.Izinga lokucindezela: ngokuvamile lihlukaniswa ngohlobo lwe-T (umfutho ophansi), uhlobo luka-K (umfutho ophakathi nendawo) nohlobo luka-P (umfutho ophezulu).Chofoza ukuze uthole ikhathalogi yamapayipi e-iron ductile.
Ngezindlela zokuxhuma zohlelo lwepayipi yensimbi ye-ductile, i-DINSEN ifingqa ngale ndlela elandelayo:
1.Uhlobo lwe-T-socket uxhumano:Kuyisixhumi esibonakalayo esivumelana nezimo, esibuye sibizwe ngokuthi isixhumi esibonakalayo se-slide-in, okuwukuxhumana okuvamile kwamapayipi ensimbi afuywayo. Ukucindezela kokuthintana phakathi kweringi yerabha nesokhethi kanye ne-spigot kwenza uphawu loketshezi. Isakhiwo sesokhethi sicabangela ukuma nokuphambuka kwe-angle ye-rubber, ingakwazi ukuzivumelanisa nendawo ethile yokuhlala, inokumelana nokuzamazama komhlaba okuthile, inezici zesakhiwo esilula,ukufakwa kalula nokubekwa uphawu okuhle, njll. Amapayipi amaningi ensimbi ahambisa amanzi emakethe asebenzisa lesi sixhumanisi.
Izinyathelo eziqondile: 1. Hlanza isokhethi kanye ne-spigot. 2. Gcoba i-lubricant odongeni olungaphandle lwe-spigot kanye nodonga lwangaphakathi lwesokhethi. 3. Faka i-spigot kusokhethi ukuze uqinisekise ukuthi isendaweni yayo. 4. Vala ngendandatho yerabha.
2. Uxhumano lwesokhethi oluzibambele ngokwakho:Yamukela isakhiwo sokuvala isixhumi esibonakalayo sohlobo lwe-T, olusetshenziswa ezimeni lapho ukugeleza kwamanzi ejikeni lepayipi kukhulu kakhulu, noma indawo yokuhlala inkulu kakhulu, okubangela ukuthi isixhumi esibonakalayo siwe kalula. Uma kuqhathaniswa nesixhumi esibonakalayo sohlobo lwe-T, indandatho yokushisela, indandatho egcina ukuvulwa okugudlukayo, i-pressure flange ekhethekile namabhawodi axhumayo ashiselwe ekugcineni kwepayipi kunezelwa ukwenza isixhumi esibonakalayo sibe nekhono elingcono lokulwa nokudonsa. Indandatho egcinayo kanye ne-pressure flange ingashelela, ukuze isixhumi esibonakalayo sibe nekhono elithile lokunweba i-axial kanye nekhono lokuchezuka, elingasetshenziswa lapho i-pier ingakwazi ukusethwa.
3.Ukuxhumana kwe-Flange:Ngokuqinisa amabhawodi axhumayo, i-flange icindezela indandatho yokuvala ukuze kufinyelelwe ukuvala isixhumi esibonakalayo, okuwukuxhumana okuqinile. Kuvame ukuba njaloesetshenziswa ngezikhathi ezikhethekile njengokuxhuma kwe-valve accessory kanye nokuxhumana kwamapayipi ahlukenes. Izinzuzo ukuthembeka okuphezulu nokubeka uphawu okuhle. Ifaneleka ezimweni lapho ububanzi bepayipi bukhulu noma ubude bepayipi bude, futhi bufaneleka nezigcawu lapho uxhumano lwepayipi kanye nezidingo zokuhlakazeka zivame khona. Kodwa-ke, uma ingcwatshwa ngokuqondile, kunengozi yokugqwala kuma-bolts, futhi ukusebenza ngesandla kunomthelela omkhulu emthelela wokuvala.
Izinyathelo eziqondile: 1. Faka ama-flange kuzo zombili iziphetho zepayipi. 2. Faka i-gasket yokuvala phakathi kwama-flange amabili. 3. Bopha i-flange ngamabhawodi.
4. I-arc welding:Izinduku zokushisela ezifanele ezifana nezinduku zokushisela ze-MG289 zingakhethwa ukuze zishiselwe, futhi amandla aphakeme kunalawo ensimbi eyinsimbi. Uma usebenzisa i-arc hot welding, preheat 500-700℃ngaphambi kwe-welding; uma induku yokushisela i-nickel-based alloy welding ene-plasticity enhle kanye nokumelana nokuqhekeka okuphezulu kukhethiwe, i-arc cold welding ingasetshenziswa futhi, enokukhiqiza okuphezulu, kodwa i-arc ebandayo ye-welding inesivinini sokupholisa okusheshayo, futhi i-weld ijwayele isakhiwo somlomo omhlophe kanye nokuqhekeka.
5. Ukushisela igesi:Sebenzisa intambo yokushisela yohlobo lwe-RZCQ, efana nentambo yokushisela yensimbi ene-magnesium, sebenzisa ilangabi eliphakathi nendawo noma ilangabi elibuthakathaka le-carburizing, futhi uphole kancane ngemva kokushisela.
Izinyathelo eziqondile: 1. Hlanza ukuphela kwepayipi. 2. Qondanisa ukuphela kwepayipi kanye nokushisela. 3. Hlola ikhwalithi ye-weld.
6. Ukuxhumana okunentambo:Ipayipi lensimbi elinemicu ohlangothini olulodwa lixhunywe kwilunga elinemicu ehambisanayo.Ifanele izicelo ezinobubanzi obuncane kanye nezingcindezi eziphansi.Kulula ukuyifaka nokuhlakaza, kodwa ukusebenza kwayo kokubekwa uphawu kulinganiselwe, futhi inezidingo eziphakeme zokunemba kokucubungula intambo nemisebenzi yokufaka.
Izinyathelo eziqondile zezinye izindlela zokuxhuma: 1. Cubungula imicu yangaphandle ekugcineni kwepayipi. 2. Sebenzisa izintambo zangaphakathi ukuze uxhume. 3.Vala nge-sealant noma nge-tape eluhlaza.
7.Uxhumano lwendandatho yokuvala uphawu lwe-Elastic: Faka indandatho yokuvala enwebekayo ekugcineni kwengxenye yepayipi ngayinye, bese ucindezela izingxenye ezimbili zamapayipi phakathi bese uzixhuma ndawonye ngesixhumi esidonsayo. Indandatho yokuvala iqinisekisa ukusebenza kokuvala uxhumano kanyeilungele amapayipi anama-diameter amancane.
8.Uxhumano lwerigi yephiko elingangeni manzi:Weld the water stop wing ring on the ductile iron pipe, and direct it into one piece ngesikhathi kwakhiwa izindonga zikakhonkolo eziqinisiwe. Ivame ukusetshenziselwa ukuxhuma amapayipi ensimbi e-ductile ukuze kukhishwe amanzi ngezindonga ezifana nemithombo yokuhlola.
Ngamafuphi, indlela yokuxhuma yamapayipi ensimbi ye-ductile ingakhethwa ngokusho kwesimo sokwakha. Ngokuqondile,uxhumano lwesokhethi lufanele amapayipi angaphansi komhlaba, uxhumano lwe-flange lufanele izikhathi ezidinga ukuhlakazeka njalo, uxhumano lwe-threaded lufanele amapayipi amancane-ububanzi, uxhumano lwe-welding lufanelekile ezindaweni ezinomfutho ophezulu kanye nokushisa okuphezulu, futhi uxhumano lwemishini lufanele izimo zesikhashana noma eziphuthumayo.
Xhumana ne-DINSEN ukuze uthole isisombululo sakho sokuxhuma ipayipi lensimbi elenziwe ngezifiso
