Imigangatho yoHlelo lwe-Tricone Drill Bit Wear kunye noHlalutyo lokuGxila

IMigangatho yoHlelo lweNkontraka yamazwe ngamazwe

I-International Contractor Association ihlela ukuguga kwebit drill ibe ngamacandelo amathathu: ukuguga kwamazinyo, ukuguga, kunye nokunciphisa i-bit diameter, kunye nemigangatho ethile emiselwe kudidi ngalunye. Olu lwahlulo lusebenza kwiindidi ezahlukeneyo zei-tricone drill bits, kuqukafaka amasuntswana okugaya izinyo,amasuntswana e-tricone yamazinyo agayiweyo, isetyenziswa xa kugrunjwa ioli, igesi, kunye namanzi.

①Umgangatho woHlelo lokuGxilwa kwezinyo

Ukunxitywa kwamazinyo kuhlelwe kumanqanaba asi-8, kunye nemigangatho yokwahlulahlula amazinyo agayiweyo kunye nokufaka amazinyo. Kubaamasuntswana e-tricone yezinyo eligidiweyo, ulwahlulo lusekelwe ekuphakameni kokugqoka. Ukuba ukuphakama kokunxiba kungaphakathi kwe-1/8 yokuphakama kwezinyo, kuhlelwe njengeNqanaba 1. Ukuba ukuphakama kokunxiba kuphakathi kwe-1/8 kunye ne-2/8 yokuphakama kwezinyo, yiNqanaba 2, njalo njalo ukuya kwiNqanaba 8. Lo mgangatho ufanelekile ngokukodwaamasuntswana e-tricone yezinyo eligidiweyokwayeamasuntswana otsaloisetyenziswe kulwakhiwo oluthambileyo.

Kubatungsten carbide faka amazinyo, ukuhlelwa kusekelwe kumlinganiselo wenani lamazinyo aphukileyo okanye alahlekileyo ukuya kwinani lilonke lamazinyo. Ukuba inani lamazinyo aphukileyo okanye alahlekileyo aphakathi kwe-1/8 yetotali, ihlelwa njengeNqanaba 1. Ukuba inani lamazinyo aphukileyo okanye alahlekileyo liphakathi kwe-1/8 kunye ne-2/8 yetotali, yiNqanaba lesi-2, njalo njalo ukuya kwiNqanaba 8. Oku kusebenzaI-Tungsten Carbide Tricone Drill Bitkunye nolunye uyilo lwamazinyo.

Ukunxitywa kwamazinyo kuchazwa ngu "T", kunye ne-T1 emele iNqanaba loku-1 lokunxiba, i-T2 imele iNqanaba lesi-2 lokunxiba, njalo njalo.

② Ukuthwala iMigangatho yoHlelo lweNgqoko

Ukuthwala ukunxitywa kuhlelwe ngokusekelwe kumlinganiselo wexesha lokusetyenziswa kwe-bit kubomi bubonke bokuthwala (ngeeyure), kunye namanqanaba asi-8 okuhlelwa. Kuzo zonke iintlobo zei-tricone rotary drill bits,kuqukaamanzi okomba amasuntswanakwayeamasuntswana amatye e-tricone, ukuba ixesha lokusetyenziswa lifikelela kwi-1/8 yobomi be-bearing, lihlelwa njengeNqanaba 1. Ukuba ixesha lokusetyenziswa lifikelela kwi-2/8 yobomi bokuzala, liyiNqanaba 2, kwaye njalo ukuya kwiNqanaba 8. Xa ixesha lokusetyenziswa liwela phakathi kwamanqanaba amabini, inqanaba eliphezulu linikezelwa.

Ukuthwala ukugqoka kuchazwa ngu "B", kunye ne-B1 ebonisa ukuba i-1/8 yobomi obuthwele isetyenzisiwe, i-B2 ibonisa i-2/8, njalo njalo. Kwiibheringi ezitywiniweyo, imeko yokutywinwa ihlelwa ngamanqanaba amathathu:

-SE (Ukutywina kuyasebenza)

-SF (Utywino alusebenzi)

-SQ (iNgxaki yokutywina)

Olu lwahlulo lubaluleke kakhuluTCI drill bitskunye namanye amasuntswana amatye e-tricone aphezulu.

③Ubumelo lweBit Diameter Wear

Ukubonisa ukunxiba kwi-diameter ye-bit, "1" imele ukuba i-bit igcina i-diameter yayo yokuqala, ngelixa "0" ibonisa ukuba ububanzi buncitshisiwe. Ubungakanani bokunciphisa ububanzi buchazwa ngee-intshi emva kwe "0". Umzekelo, "01/2" ithetha ukuba i-bit's diameter ithotywe nge-1/2 intshi. Oku kubalulekile ekugcineni ukusebenza kakuhle kokomba kwiinkqubo ezahlukeneyo, kubandakanywaioli, igesi, kunyeukugrunjwa kwequla lamanzi.
