Ngiyakuthanda ukudala okuqukethwe kwamahhala okugcwele izeluleko zabafundi bami, wena. Angilwamukeli uxhaso olukhokhelwayo, umbono wami owami, kepha uma uthola izincomo zami zilusizo futhi ugcina uthenga okuthile okuthandayo ngesinye sezixhumanisi zami, bengingathola ikhomishini ngaphandle kwezindleko ezengeziwe kuwe.

Kunokuxhumana okungu-4 okuvame kakhulu kwe-PEX okuhlanganisa i-crimp PEX, insimbi engagqwali yokuqinisa, i-push-to-connect, kanye nokunwetshwa okubandayo ngamaringi aqinisa i-PEX. Namuhla sizoxoxa kuphela ngokuhlanganyela kwe-crimp PEX.
Kulokhu okuthunyelwe sizomboza:
Izinyathelo Eziyisi-6 Zokuthola I-PEX
Udinga umsiki wepayipi, ithuluzi le-crimp, indandatho ye-crimp, kanye ne-go/no-go gauge yokwenza umhlanganyeli we-PEX we-crimp. Ngemva kokuqoqa amathuluzi adingekayo landela izinyathelo okuxoxwe ngazo lapha. Isinyathelo soku-1: Sika ipayipi uye kubude obufunekayo Nquma ubude ofuna ukusika ipayipi. Bese uthatha umsiki wepayipi bese usika ipayipi ubude obudingekayo. Ukusika kufanele kube bushelelezi futhi kube isikwele kuze kube sekupheleni kwepayipi. Uma uyenza ibe mahhadlabhadla, ibe mahlebezi, noma i-engeli uzogcina wenze ukuxhumana okungaphelele okufanele ufune ukukugwema. Isinyathelo sesi-2: Khetha indandatho Kunezinhlobo ezi-2 zamasongo e-copper crimp. Enye yi-ASTM F1807 kanti enye yi-ASTM F2159. I-ASTM F1807 isetshenziselwa ukufaka insimbi futhi i-ASTM F2159 isetshenziselwa ukufaka ipulasitiki. Ngakho-ke, khetha iringi ngokuya ngohlobo lokufafaza ofuna ukulenza. Isinyathelo sesi-3: Shelelezisa iringi Shelelezisa indandatho yecrimp cishe amayintshi angu-2 udlule phezu kwepayipi le-PEX. Isinyathelo sesi-4: Faka i-Fitting Faka okokufakela (ipulasitiki/ insimbi) epayipini futhi uqhubeke uyishelela ize ifike lapho ipayipi nokufaka kuthintana khona. Kunzima ukunquma ibanga njengoba lihluka kusuka kokubonakalayo kuye kokubalulekile kanye nomkhiqizi kuye kumkhiqizi. Isinyathelo sesi-5: Cindezela indandatho usebenzisa Ithuluzi le-Crimp Ukuze ucindezele indandatho phakathi nendawo yomhlathi wethuluzi le-crimp phezu kweringi futhi uyibambe kuma-degree angu-90 ukuya endaweni efanele. Imihlathi kufanele ivalwe ngokuphelele ukuze uxhumano oluqinile lwenziwe. Isinyathelo sesi-6: Hlola Ukuxhumana ngakunye Ngokusebenzisa i-go/no-go gauge qinisekisa ukuthi uxhumano ngalunye lwenziwe kahle. Ungaphinda unqume ukuthi ithuluzi le-crimping lidinga ukulinganiswa kabusha noma cha nge-go/no-go gauge. Khumbula ukuthi ukuxhumana okuphelele akusho ukuxhumana okuqine kakhulu ngoba ukuxhumana okuqine kakhulu nakho kuyingozi njengoxhumano oluxekethile. Ingase yenze ipayipi noma isifakelo sonakaliswe kuphumele endaweni yokuvuza.Izinhlobo zegeji ye-Go/No-Go
Izinhlobo ezimbili zamageji okuhamba/ukungahambeki ayatholakala emakethe. Uhlobo 1: Isikhala Esisodwa - I-Go / No-Go Stepped Cut-Out Gauge 2: Isikhala Esikabili - I-Go/No-Go Cut-Out GaugeI-Single Slot – Hamba / No-Go stepped Cut-Out Gauge
Igeji ye-single-slot go/no-go step-out gauge kulula futhi kuyashesha ukuyisebenzisa. Uma ugoqa kahle uzoqaphela ukuthi iringi yecrimp ingena kusikwa okumise okuka-U kuze kufike emugqeni ophakathi kwezimpawu ze-GO kanye ne-NO-GO bese ima phakathi nendawo. Uma ubona ukuthi i-crimp ayingeni ekusikeni okumise okuka-U noma uma i-crimp icindezelwe ngokweqile lokho kusho ukuthi awuzange uhlike ngendlela efanele. Khona-ke kufanele uhlukanise ukuhlanganisa bese uqala inqubo futhi kusukela kusinyathelo 1.I-Double Slot – Go/No-Go Cut-Out Gauge.
Ukuze uthole i-double slot go/no-go gauge kufanele wenze isivivinyo se-Go kuqala bese emva kwalokho uhlole ukuthi ungahambi. Kufanele ubeke kabusha igeji ngaphambi kokwenza ukuhlolwa kwesibili. Uma ubona ukuthi iringi yecrimp ingena endaweni ethi "GO" futhi ungakwazi ukuzungezisa ukuzungeza iringi okusho ukuthi ilunga lenziwe ngendlela efanele. Uma ubona okuphambene, lokho kusho ukuthi i-crimp ayingeni endaweni ye-"GO" noma ingena endaweni ethi "NO-GO" okusho ukuthi ukujoyina akwenziwanga ngendlela efanele. Uma kunjalo, kufanele uhlukanise ukuhlangana bese uqala inqubo ukusuka kusinyathelo 1.Ukubaluleka kwegeji ye-Go/No-Go
Kwesinye isikhathi abasebenza ngamapayipi baziba igeji ye-go/no-go. Uyazi, ukungahloli ilunga lakho ngegeji ye-go/no-go kungase kuholele ekulinganeni okomile. Ngakho-ke, sizoncoma kakhulu ukuthi ube ne-gauge. Uzoyithola esitolo sokudayisa esiseduze. Uma ungakwazi ukuyithola esitolo sizophakamisa ukuthi u-ode ku-inthanethi. Uma ukhohlwe ukuthatha igeji nganoma yiliphi ithuba ungasebenzisa i-micrometer noma i-vernier ukukala ububanzi obungaphandle beringi ye-crimp ngemva kokuqeda umsebenzi wokucwilisa. Uma ilunga lenziwe ngendlela efanele uzothola ububanzi buwela ebangeni okukhulunywe ngalo eshadini.| Usayizi Weshubhu Lokuqamba (Intshi) | Ubuncane (Intshi) | Ubuningi (Intshi) |

amazwi okugcina
Ukulungisa umgomo wakho wokugcina ngaphambi kokuqala iphrojekthi kubalulekile ukwenza iphrojekthi iphumelele. Ngakho-ke, lungisa okuhlosiwe kuqala, futhi ungajahi ngisho noma uyisifaki esinekhono. Thatha isikhathi esanele sokuhlola ukuphelela kwelunga ngalinye futhi yebo ungalokothi uzibe igeji ye-go/no-go. Uma ukoma kwenzeka ingozi izokwenzeka futhi ngeke usithole isikhathi sokuyilungisa.
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
