I-PEX imele i-cross-linked polyethylene. Yaziwa nangokuthi i-XPE noma i-XLPE. Ukunwetshwa kwe-PEX kuthathwa njengokukhetha kwesimanjemanje nokuthuthukile kwamapayipi amanzi asekhaya, izinhlelo zokufudumeza ezikhazimulayo ze-hydronic kanye nezinhlelo zokupholisa, ukufakwa kwezintambo zezintambo zikagesi ezidonsa kanzima, ukuthuthwa kwamakhemikhali, nokuthuthwa kwendle nama-slurries. Ngakolunye uhlangothi, i-crimp iyisixhumi sikagesi esingathengiswa esisetshenziselwa ukuhlanganisa izintambo eziboshiwe ndawonye.
Kulokhu okuthunyelwe sizomboza:
Ukwandiswa kwe-PEX
Udinga amapayipi ahlanzekile futhi ahlanzekile amise okwesikwele ukuze wenze ukunwetshwa kwe-PEX. Kufanele usebenzise ithuluzi le-expander ukuze wandise izindandatho ngokuvumelana nomyalelo onikezwe umenzi. Ukugcinwa ngendlela efanele kanye nokusetshenziswa kokugcoba kuzokusiza ukuthi uthole ukuxhumana okuhlala isikhathi eside kwekhwalithi ephezulu. Ngakolunye uhlangothi, ukunwetshwa okungalungile kungase kuholele ekuvuzeni kunciphise isikhathi sokuphila sepayipi neshubhu - ngakho-ke, qaphela.Indlela Eyisisekelo Yokusebenza Yokunwetshwa kwe-PEX
I-PEX inesici esikhethekile sokwandisa kanye nenkontileka. Ekuqaleni, ubukhulu bamapayipi, amashubhu, kanye nomkhono uyakhuliswa ukuze kube lula ukufaka. Lapho umkhono wepulasitiki ushibilika futhi uhlangana endaweni yokuxhuma i-PEX iyashwabana ukuze ukufakwa kuqine.Ungayifaka kanjani i-PEX Tubing?
Okokuqala, kufanele unqume ubude be-PEX bese usika i-PEX ngokwesidingo sakho. Bese wengeza indandatho yokunweba ekugcineni kwe-PEX. Ngemva kwalokho gcoba inhloko enwetshiwe bese ubeka inhloko yokunweba evalwe ngokugcwele ekugcineni kwe-PEX. Ngokwenza kanjalo, ungaqinisekisa ukuzungeza nokufinyela okufanele. Okulandelayo cindezela i-trigger futhi uyibambe kuze kube yilapho ichopho lendandatho lishaya ngemuva kwekhoni yesinweshi. Uzoqaphela ukuthi ikhanda liyashintsha kancane ngokunwetshwa ngakunye. Lapho i-ringtone iphuma cindezela i-trigger futhi ubale ukunwebeka okwengeziwe okungu-3-6 ukuze inganciphisi ibuyele kusayizi ngokushesha. Lapho indandatho isiphumile, gcina i-trigger icindezelekile futhi ubale ukunwetshwa okwengeziwe okungu-3-6. Ukwenza lokhu kuzoqinisekisa ukuthi unesikhathi esanele sokuxhuma okufakela kwakho ngaphandle kokuhlehlela emuva kusayizi ngokushesha okukhulu. Kufanele uhlole ukufakwa ngemuva kwamahora angama-24. Kufanele uqaphele izinga lokushisa lendawo yokusebenza ngoba izinga lokushisa linomphumela obalulekile ekwandeni. Ngakho-ke, kuphinde kuthinte inqubo yokufaka.Izinzuzo Zokunwetshwa kwe-PEX
Ukuguquguquka okuphezulu, ukuqina, ubude bekhoyili ende, nesisindo esilula kanye nokumelana okuhle nomonakalo owenziwe yiqhwa kanye nokugqwala, umgodi, nokukala kwenza i-PEX yaduma phakathi kwamapayipi amanzi. Njengoba ukuxhuma uhlelo lwe-PEX kulula ukulufunda kuyathandwa futhi phakathi kwabasanda kuhlanganyela. Uma kuqhathaniswa nethusi ne-PEX yethusi ihlala isikhathi eside. Ukuvumelana nezimo okunikezwa yi-PEX kunciphisa ukuxhumeka kufika kuhhafu kwezinye izinhlelo zokusebenza. Ngakho-ke, i-PEX ibhekwa njengenye yezindlela zokufaka amapayipi ezisheshayo ezitholakalayo.Izingozi Zokunwetshwa kwe-PEX
I-Leaching BPA namanye amakhemikhali anobuthi, athambekele ezinambuzaneni, amagciwane, nokuhlasela kwamakhemikhali, ukuzwela ukukhanya kwe-UV, izinga lokushisa eliphezulu, kanye nokwenzeka kokuvuza kwamanzi yikona okungalungile okuyinhloko kokunwetshwa kwe-PEX. Ake ngikhulume okwengeziwe ngephuzu ngalinye. Kunezinhlobo ezi-3 ze-PEX eziqanjwe nge-PEX A, i-PEX B, ne-PEX C. Uhlobo A no-C luvame ukuba nezinkinga zokuleaching, uhlobo B kuphela olubhekwa njengephephile. Njengoba i-PEX yenziwe ngezinto zepulasitiki maningi amathuba okuthi ilinyazwe izinambuzane namakhemikhali. Ezinye izinkampani ezilawula izinambuzane zithi kusengozini enkulu ekulimaleni izinambuzane. Iningi labakhiqizi be-PEX baphakamisa inani elilinganiselwe lokuchayeka kokukhanya kwe-UV futhi abanye babakhiqizi baphakamisa ubumnyama obuphelele. Kubalulekile ukuqaphela ngesikhathi sokufakwa kwe-PEX. Njengoba i-PEX ingase yonakaliswe izinga lokushisa eliphezulu akufanele ufake i-PEX ezindaweni lapho izochayeka khona ekukhanyeni okwehlile noma isifudumezi samanzi. I-PEX ayinazo izinto ezilwa namagciwane. Ngoba impahla ekwazi ukungena kancane yoketshezi lwe-PEX ingangena epayipini futhi ukungcola kuzokwenzeka.Inkalipho
I-Crimp ilula kakhulu kunokufakwa kwe-PEX. Uzoqonda ubulula bayo ezigabeni ezilandelayo. Asambe.I-Basic Working Mechanism ye-Crimp
Kufanele ufake isiphetho esihlutshiwe socingo kusixhumi se-crimp, Bese usikhubaza ngokusika intambo ngokuqinile. Udinga itheminali, intambo, kanye nethuluzi lokugoqa (i-Crimping plier) ukuze wenze le nqubo. Njengoba uxhumano lwe-crimp lungavumeli noma yiliphi igebe phakathi kwezintambo zocingo kuphumelela kakhulu ukumelana nokwakheka kokugqwala ngokuvimbela ukungena kokubili komoyampilo kanye nomswakama.Indlela yokwenza i-Crimping Joint?
Isinyathelo sokuqala ukuthenga ithuluzi le-pex crimping. Ungathenga i-ratchet crimper noma i-crimper manual kuye ngokukhetha kwakho kanye nesabelomali. I-ratchet crimper kulula ukuyisebenzisa kune-crimper eyenziwa ngesandla. Bese ukhetha i-crimping die efanele igeji yocingo oyisebenzisayo. Ngakho-ke, kubalulekile ukunquma i-wire gauge. Intambo ebomvu inegeji esukela ku-22-16, intambo eluhlaza okwesibhakabhaka inegeji engu-16-14, kanti intambo ephuzi inegeji engu-12-10. Uma ucingo lungezi ne-insulation enemibala ungabheka ukupakishwa kwalo ukuze uthole igeji. Bese udweba ucingo nge-crimper bese ususa isivikeli. Ngemva kokuhlubula izintambo ezimbalwa sonta lezo ndawonye bese ufaka lolu cingo olusontekile kusixhumi. Ukubeka umgqomo wesixhumi endaweni efanelekile ye-crimper ukuwukhama. Uma uthola ukuthi uxhumano luxega, ungathengisa ilunga phakathi kwesixhumi nocingo. Ekugcineni, vala uxhumano nge-tape kagesi.Izinzuzo zeCrimp
Ukufakwa kwe-crimp ishibhile, kulula, futhi kuyashesha. Njengoba ukuxhunywa kwe-crimp kudala uphawu olubamba umoya phakathi kwekhebula nesixhumi kuvikelwe ezimeni zemvelo ezinjengomswakama, isihlabathi, uthuli nokungcola.I-Cons of Crimp
I-crimp fitting ine-conggiligible con to mention. I-con eyodwa ingaba ukuthi udinga amathuluzi athile ohlobo ngalunye lwetheminali engakubiza kakhulu.IZwi Final
Ukufakwa kwe-crimp kubonakala kulula kimi kunokulinganisa kwe-PEX. Futhi, i-cons of the crimp fitting incane kune-PEX expansion fitting. Ngokuya ngesidingo sakho nezimo ungasebenzisa kokubili ukwenza ukuxhumana. Ingxenye ebalulekile ukwenza isinqumo esifanele esimweni esithile. Uma unolwazi olunzulu mayelana kokubili okufakwayo futhi uyazi futhi umehluko wabo ukwenza isinqumo esifanele kuzoba lula kuwe.
