Ndiyakuthanda ukudala umxholo okhululekileyo ogcwele iingcebiso kubafundi bam, wena. Andilwamkeli uxhaso oluhlawulelweyo, uluvo lwam lolwam, kodwa ukuba ufumanisa ukuba izindululo zam ziluncedo kwaye ugqibela ngokuthenga into oyithandayo ngenye yeekhonkco zam, ndingafumana ikhomishini ngaphandle kwendleko ezongezelelweyo kuwe.

Kukho i-4 yoqhagamshelo oluqhelekileyo lwe-PEX olubandakanya i-crimp PEX, i-clamp yensimbi engenasici, i-push-to-connect, kunye nokwandiswa okubandayo nge-PEX-reinforcing rings. Namhlanje siza kuxoxa kuphela ngokudibeneyo kwe-PEX yecrimp.
Kule posi siza kugubungela:
Amanyathelo ama-6 e-Crimp PEX
Udinga isixhobo sokusika umbhobho, isixhobo crimp, iringi yecrimp, kunye ne go/no-go gauge ukwenza i-crimp PEX joint. Emva kokuqokelela izixhobo eziyimfuneko landela amanyathelo axoxwe apha ngokulandelayo. Inyathelo 1: Sika uMbhobho ukuya kubude obufunwayo Qinisekisa ubude ofuna ukusika umbhobho kuyo. Emva koko thabatha umsiki wepayipi kwaye usike umbhobho ubude obufunekayo. Ukunqunyulwa kufuneka kube lula kunye nesikwere ukuya ekupheleni kombhobho. Ukuba uyenza rhabaxa, ijijekile, okanye i-engile uya kugqiba wenze unxibelelwano olungagqibelelanga ekufuneka uluphephe. Inyathelo 2: Khetha iRingi Kukho iintlobo ezi-2 zamakhonkco e-copper crimp. Enye yi-ASTM F1807 kwaye enye yi-ASTM F2159. I-ASTM F1807 isetyenziselwa ukufakwa kwentsimbi kwaye i-ASTM F2159 isetyenziselwa ukufaka iplastiki. Ngoko ke, khetha umsesane ngokohlobo lofako ofuna ukulwenza. Inyathelo lesi-3: Slayida iRingi Slayidela iringi yecrimp phantse i-intshi ezi-2 udlule phezu kombhobho wePEX. Inyathelo 4: Faka iFitting Faka ukufakela (iplastiki/intsimbi) kumbhobho kwaye uhlale uyityibilikisa de ifike kwindawo apho umbhobho kunye nokufakwa kuthintana. Kunzima ukumisela umgama njengoko uhluka kwizinto eziphathekayo kunye nomvelisi ukuya kumenzi. Inyathelo lesi-5: Cofa iRingi usebenzisa isixhobo seCrimp Ukucinezela iziko leringi umhlathi wesixhobo se-crimp phezu kweringi kwaye uyibambe kwii-90 degrees ukuya kwi-fitting. Imihlathi kufuneka ivalwe ngokupheleleyo ukwenzela ukuba udibaniso oluqinileyo lwenziwe. Inyathelo 6: Jonga uQhagamshelwano ngalunye Ukusebenzisa i-go/no-go gauge qinisekisa ukuba uqhagamshelwano ngalunye lwenziwe ngokugqibeleleyo. Ungajonga kwakhona ukuba isixhobo sokukrazula sifuna uhlengahlengiso okanye hayi nge go/no-go gauge. Khumbula ukuba uqhagamshelo olugqibeleleyo aluthethi uqhagamshelo oluluqilima kakhulu kuba uqhagamshelo oluqine kakhulu lukwayingozi njengodibaniso olukhululekileyo. Ingenza ukuba umbhobho okanye ukulungeleka konakele kubangele indawo yokuvuza.Iindidi zegeji yeGo/No-Go
Iintlobo ezimbini zeegeyiji zokuhamba / zokungahambi ziyafumaneka kwimarike. Uhlobo loku-1: I-Slot enye-I-Hamba / i-No-Hamba i-Slot-Out Gauge Uhlobo lwe-2: i-Slot ephindwe kabini-Hamba / i-No-Go Cut-Out GaugeI-Slot eNye-Hamba / Hayi-Hamba iNyathelwe Sika iGauji
I-single-slot go/no-go stepped-out gauge ilula kwaye iyakhawuleza ukuyisebenzisa. Ukuba ucrimp ngokugqibeleleyo uya kuqaphela ukuba iringi yecrimp ingena kwi-milo engu-U esikiweyo ukuya kumgca ophakathi kwe-GO kunye ne-NO-GO yeempawu kunye nokumisa phakathi. Ukuba uyaqaphela ukuba i-crimp ayingeni kwi-cut-shaped cut-out okanye ukuba i-crimp icinezelekile ngokugqithisileyo oko kuthetha ukuba awuzange udibanise ngokuchanekileyo. Emva koko kufuneka uqhawule umdibaniso kwaye uqale inkqubo kwakhona ukusuka kwinqanaba loku-1.Slot kabini-Hamba/No-Go Cut-Out Gauge.
Kuba kabini slot go/no-go gauge kufuneka wenze uvavanyo Hamba kuqala kwaye ke uvavanyo akukho-hamba. Kufuneka ubeke kwakhona igeyiji phambi kokwenza uvavanyo lwesibini. Ukuba uqaphela ukuba i-crimp ring ingena kwi-slot ye-"GO" kwaye unokujikeleza kwi-circumference ye-ring oko kuthetha ukuba i-joint yenziwe ngokuchanekileyo. Ukuba uqaphela okuchaseneyo, oko kuthetha ukuba i-crimp ayifaki kwi-slot "GO" okanye ingena kwi-slot ethi "NO-GO" oko kuthetha ukuba i-joint ayenziwanga ngokuchanekileyo. Kwimeko apho, kuya kufuneka uqhawule umdibaniso kwaye uqale inkqubo ukusuka kwinqanaba loku-1.Ukubaluleka kwegeji yeGo/No-Go
Ngamanye amaxesha abatywini bayayihoya igeyiji ye-go/no-go. Uyazi, ukungavavanyi umdibaniso wakho kunye ne-go/no-go gauge kunokukhokelela ekulinganeni okomileyo. Ke, siya kucebisa kakhulu ukuba ube negeyiji. Uya kuyifumana kwivenkile yokuthengisa ekufutshane. Ukuba awukwazi ukuyifumana kwivenkile yokuthengisa siya kucebisa ukuba u-odole kwi-intanethi. Ukuba ulibele ukuthatha igeyiji ngalo naliphi na ithuba ungasebenzisa i-micrometer okanye i-vernier ukulinganisa i-diameter yangaphandle yeringi ye-crimp emva kokugqiba umsebenzi we-crimping. Ukuba umdibaniso wenziwa ngokufanelekileyo uya kufumana ububanzi buwela kuluhlu olukhankanywe kwitshathi.| Ubungakanani bombhobho oqhelekileyo (i-intshi) | Ubuncinci (i-intshi) | Ubuninzi (i-intshi) |
| 3/8 | 0.580 | 0.595 |
| 1/2 | 0.700 | 0.715 |
| 3/4 | 0.945 | 0.960 |
| 1 | 1.175 | 1.190 |
Amazwi okugqibela
Ukulungisa injongo yakho yokugqibela ngaphambi kokuba uqalise iprojekthi kubalulekile ukwenza iprojekthi iphumelele. Ke, lungisa into ojolise kuyo kuqala, kwaye ungangxami nokuba ungumfakeli onobuchule. Thatha ixesha elaneleyo ukujonga ukugqibelela kwejoyinti ngalinye kwaye ewe ungaze ungayihoyi igeyiji yokuya/yokuhamba. Ukuba ukoma komile kwenzeka ingozi iya kwenzeka kwaye awuyi kufumana ixesha lokuyilungisa.
NdinguJoost Nusselder, umseki weZixhobo zeGqirha, umthengisi womxholo, kunye notata. Ndiyathanda ukuzama izixhobo ezitsha, kwaye kunye neqela lam ndiye ndenza amanqaku ebhlog anzulu ukusukela ngo-2016 ukunceda abafundi abathembekileyo ngezixhobo kunye neengcebiso zokwenza.
