Ikhwalithi ephezulu yensimbi engagqwali tube umkhiqizi
Ipayipi lensimbi engagqwali iphephile, inokwethenjelwa, ihlanzekile, ayihambisani nemvelo, iyonga futhi iyasebenza. Udonga oluncane lwepayipi kanye nokuthuthukiswa okuphumelelayo kwezindlela ezintsha zokuxhuma ezinokwethenjelwa, ezilula futhi ezilula zenza kube nezinzuzo ezingenakushintshwa zamanye amapayipi. Kuzosetshenziswa kakhulu kwezobunjiniyela, kudume kakhulu futhi kuthembise.
Ngenxa yokuthi insimbi engagqwali inezindawo eziningi ezinhle ezidingekayo ngezinto zokwakha, kungathiwa iyingqayizivele ezinsimbi, futhi ukuthuthukiswa kwayo kuyaqhubeka. Ukuze kwenziwe insimbi engagqwali ingathathi hlangothi kakhulu ekusetshenzisweni kwendabuko, izinhlobo ezikhona zithuthukisiwe, futhi insimbi engagqwali entsha iyathuthukiswa ukuze ihlangabezane nezidingo eziqinile zezinhlelo zokusebenza ezithuthukisiwe zezakhiwo. Ngenxa yokuthuthukiswa okuqhubekayo kokusebenza kahle kokukhiqiza kanye nekhwalithi, insimbi engagqwali ibe enye yezinto ezingabizi kakhulu ezikhethwe abaklami bezakhiwo.
Insimbi engagqwali ihlanganisa ukusebenza, ukubukeka kanye nezici zokusebenzisa, ngakho insimbi engagqwali isazoba enye yezinto zokwakha ezihamba phambili emhlabeni.
Ngokusetshenziswa kwenqubomgomo yaseShayina yezinguquko kanye nokuvula amathuba, umnotho wezwe usukhule ngokushesha, futhi kwakhiwa inqwaba yezindlu zasemadolobheni, izakhiwo zomphakathi kanye nezindawo zokuvakasha, okubeka phambili izidingo ezintsha zokuhlinzekwa kwamanzi ashisayo kanye nokuhlinzekwa kwamanzi asekhaya. . Ikakhulukazi, abantu banaka kakhulu inkinga yekhwalithi yamanzi, futhi nezidingo ziyanda. Ipayipi lensimbi elakhiwe ngothayela, ipayipi elivamile, lizohoxa kancane kancane esigabeni somlando ngaphansi kwethonya lezinqubomgomo zezwe ezifanele ngenxa yokugqwala kwalo. Ipayipi lepulasitiki, ipayipi eliyinhlanganisela kanye nepayipi lethusi sekuphenduke amapayipi avamile ohlelweni lwamapayipi. Nokho, ezimweni eziningi, ipayipi lensimbi engagqwali linezinzuzo ezengeziwe, ikakhulukazi ipayipi lensimbi engagqwali elinezindonga ezincane ezinogqinsi oluwu-0.6 ~ 1.2mm kuphela. Kuhlelo lwamanzi okuphuza oluseqophelweni eliphezulu, uhlelo lwamanzi ashisayo kanye nohlelo lokuhlinzeka ngamanzi olubeka ukuphepha nokuthuthwa kwendle kuqala, lunezici zokuphepha, ukwethembeka, ukuthuthwa kwendle, ukuvikelwa kwemvelo, umnotho kanye nokusetshenziswa. Kufakazelwe umkhuba wobunjiniyela ekhaya naphesheya ukuthi ingelinye lamapayipi amasha, akonga ugesi kanye nokuvikela imvelo asebenza kahle kakhulu ohlelweni lokuphakelwa kwamanzi. Kuphinde kube yipayipi lokuphakelwa kwamanzi elincintisana kakhulu, elizodlala indima engenakuqhathaniswa ekwenzeni ngcono izinga lamanzi kanye nokwenza ngcono izinga lokuphila kwabantu.
Ohlelweni lwamapayipi okuhambisa amanzi okwakha, ngenxa yokuthi ipayipi lensimbi eliyisithako seliqede umlando okhazimulayo weminyaka eyikhulu, amapayipi epulasitiki amasha ahlukahlukene kanye namapayipi ayinhlanganisela athuthuke ngokushesha, kodwa amapayipi ahlukahlukene asenokusilela okuthile ngamazinga ahlukahlukene, okukude kakhulu. ukuhlangabezana nezidingo zohlelo lwamapayipi okuhambisa amanzi kanye nezidingo zikazwelonke zamanzi okuphuza kanye nekhwalithi yamanzi ahlobene. Ngakho-ke, ochwepheshe abafanelekile babikezela ukuthi ukwakha amapayipi okuhambisa amanzi ekugcineni kuzobuyela esikhathini samapayipi ensimbi. Ngokwesipiliyoni sokufaka isicelo phesheya, ipayipi lensimbi engenasici elinezindonga ezincane libonwa njengelinye lamapayipi anokusebenza okuhle kakhulu okubanzi.
Ipayipi lensimbi engagqwali elincanyana, elakhiqizwa futhi lasetshenziswa kuphela eShayina ngasekupheleni kwawo-1990, liwumndeni omusha osafufusa emkhakheni wezinto zamapayipi. Isetshenziswe kabanzi ekwakheni amanzi kanye namapayipi amanzi okuphuza aqondile.
Ipayipi lensimbi engagqwali elincanyana liqinile futhi liye laqashelwa umphakathi wonjiniyela, futhi izinhlangano ezifanele ziqala ekwehliseni ukushuba kodonga nokunciphisa intengo, ukuze kube lula ukuphromotha okwengeziwe. Ikakhulukazi, intengo yepayipi yensimbi engenasici enobubanzi obuncane ayiphezulu, ngakho-ke indlela yokuxhuma esekelayo, ukwethembeka kanye nentengo yokufakwa kwamapayipi yizici eziyinhloko ezinquma ukuthuthukiswa kwayo. Abathuthukisi basekhaya bazenzele ngokuzimela ubuchwepheshe bokuxhuma kanye nokufakwa kwamapayipi eSichuan, Guangdong, Zhejiang, Jiangsu nakwezinye izindawo, okuyipayipi elithembisayo. UMnyango Wezokwakha kanye neminyango ethintekayo nayo ibheka ukubaluleka okukhulu kulolu hlobo olusha lwamapayipi. Ngokwesaziso sokukhuthazwa nokusetshenziswa kwesilinganiso "sobubanzi obuphezulu kuya odongeni kanye nokunemba okuphezulu kwamapayipi amanzi ensimbi engenasici kanye nomfutho ophezulu wokuphakelwa kwamanzi, ukufakwa kwamapayipi okusekela nobuchwepheshe obukhethekile" esikhishwe isikhungo sokuphromotha ukuphathwa kwemakethe yaseChina kanye ne-gksz [2001] No. 71 idokhumenti, Ukwenziwa kwaziwe kanye nokusetshenziswa kobuchwepheshe bepayipi lensimbi engagqwali enezindonga ezincane ezinodonga oluncane kubaluleke kakhulu ukuthuthukisa izinga lezakhiwo zesimanje zaseShayina kanye nokwenza ngcono kanye nokuqinisekisa izinga lamanzi okuphakelwa kwamanzi.
Ngesikhathi esifanayo, uMnyango Wezokwakha ubheka ukubaluleka okukhulu ekukhuthazeni nasekusetshenzisweni kwamapayipi ensimbi engagqwali anezindonga ezincane《 Izinga lemboni lepayipi lamanzi lensimbi engenasici elincanyana lakhishwa futhi lasetshenziswa ngo-2001. ubunjiniyela bukhishwe nguMnyango Wezokwakha futhi bulungiswa yi-Tongji University. Njengamanje, kunabakhiqizi abangochwepheshe eSichuan, Guangdong, Zhejiang, Jiangsu nakwezinye izindawo ukukhiqiza amapayipi ensimbi engenasici anezindonga ezincane, futhi imikhiqizo isivuthiwe. Ngakho-ke, isikhathi sokuthandwa nokusetshenziswa sesifikile.
Kunezindlela ezihlukahlukene zokuxhuma zamapayipi ensimbi engagqwali. Izinhlobo ezivamile zokufakwa kwamapayipi uhlobo lokucindezelwa, uhlobo lokucindezela, uhlobo lwenyunyana, uhlobo lwe-push, uhlobo lwentambo yokusunduza, uhlobo lwe-socket welding, uxhumano lwe-union flange, uhlobo lwe-welding kanye nemodi yokuphuma kochungechunge lokuxhumana oluhlanganisa ukushisela nokuxhumana kwendabuko. Lezi zindlela zokuxhuma zinezigaba ezahlukene zohlelo lokusebenza ngokuvumelana nezimiso zazo, kodwa eziningi zazo zilula ukuzifaka, ziqinile futhi zithembekile. Iningi lendandatho yokuvala noma izinto ze-gasket ezisetshenziselwa ukuxhuma irabha ye-silicone, i-nitrile rubber kanye ne-EPDM ehlangabezana nezidingo zezindinganiso zikazwelonke, eziqeda ukukhathazeka kwabasebenzisi.
1.Ukuphuka kwamapayipi: nqamula ipayipi ngokobude obudingekayo. Uma uphula ipayipi, ungasebenzisi amandla amaningi ukuze uvimbele ipayipi ukuthi liphume nxazonke.
2. Ukuqothula: ngemva kokunqunywa kwepayipi, i-burr izosuswa ukugwema ukusika indandatho yokuvala.
3. Ukumaka: ukuze ufake ngokuphelele ipayipi yensimbi esisekelweni sokufakwa kwepayipi, ubude bokufaka kufanele buphawulwe futhi budonswe ekugcineni kwepayipi.
4. Umhlangano: indandatho yokuvala izofakwa ngendlela efanele ku-U-groove yokufaka ipayipi, faka ipayipi esisekelweni sokufaka ipayipi bese ulinda ukugoqa.
5. I-Crimping: ngesikhathi se-crimping, ingxenye ye-convex yokufaka ipayipi ifakwe emgodini we-concave we-die, futhi umhlathi u-perpendicular ku-axis yepayipi.
6. Ukuhlola: ngemva kokugoqa, hlola usayizi we-crimping ngegeji ekhethekile.
