Zithini izinto eziphambili zeRoller Reamer Cutter kunye nomlinganiselo wazo?

Xa uyila, ukhetha, okanye uthengaI-Roller ReamerUmsiki, izinto kunye nobukhulu zizinto ezibalulekileyo ezichaphazela ngqo ukusebenza kwayo, ixesha layo lokuphila, kunye nokusetyenziswa kwayo. Nazi izinto ezibalulekileyo ekufuneka uziqwalasele:

1. Izinto ekufuneka ziqwalaselwe xa ukhetha izinto

Izinto eziphambili ezigugileyo zeRoller Reamer Cutter zizicuthi zeroller kunye nomzimba. Ukukhethwa kwezinto kufuneka kuthathele ingqalelo ubulukhuni, ukumelana nokuguguleka, ukuqina kwempembelelo, kunye nokumelana nobushushu obuphezulu.

(1) Izinto Zokusika Iirola

-Tungsten Carbide (WC)

- Eyona ndlela ixhaphakileyo yokukhetha, enika ubulukhuni obuphezulu (HRA 90+) kunye nokumelana nokuguguleka.

- Ifanelekile kwiindlela eziphakathi ukuya kweziqinileyo kakhulu (umz., igranite, iquartzite).

- Nika ingqalelo kumxholo we-cobalt (Co) (6% ~ 15%)—i-cobalt ephezulu iphucula ukuqina kodwa inciphisa ubulukhuni.

- I-PDC (iPolycrystalline Diamond Compact)

- Ifanelekile kwiindlela ezithambileyo ukuya kweziphakathi ezinzima, kwaye inokumelana nokuguguleka okuhle kodwa ikwazi ukumelana nempembelelo ephantsi.

- Isetyenziswa kakhulu ekubholeni ioyile kunye nokuhlola ijoloji.

- Iingubo zeCeramic okanye eziqinileyo kakhulu (umz., iTiN, iDLC)

- Isetyenziswa kwiindawo ezirhabaxa kakhulu kodwa ngexabiso eliphezulu.

(2) Izinto zomzimba

- Intsimbi ye-Alloy (umz., 4140, 4340)

- Ifuna unyango lobushushu bokucima nokupholisa (QT) ukuze komelezwe amandla nokuqina.

- Intsimbi Engagqwaliyo (umz., 17-4PH)

- Isetyenziswa kwiindawo ezirhabaxa (umz., ukugrumba olwandle, ukwakheka kwe-asidi).

- Unyango lomphezulu (umz., i-chrome plating, i-nitriding) lunokuphucula ukumelana nokuguguleka.

Amanqaku oKhetho lwezinto ezibalulekileyo:

✅ Khetha izinto zokusika iirola ngokusekelwe kubulukhuni bokwakheka kwazo (ilitye eliqinileyo → ikhabhayithi ye-tungsten, ilitye elithambileyo → i-PDC).

✅ Cinga ngemithwalo yempembelelo ukuze uphephe ukuqhekeka nokuqhekeka.

✅ Kwiindawo ezirhabaxa (umz., amanzi anetyuwa, i-H₂S), sebenzisa intsimbi engagqwaliyo okanye izinto zokugquma ezikhethekileyo.

2. Izinto eziqwalaselwayo kubungakanani

Ubukhulu beRoller Reamer Cutter buchaphazela ngokuthe ngqo ukuhambelana kwayo nobubanzi bemigodi, uzinzo, kunye nokusebenza kakuhle kokusika.

(1) Ububanzi obungaphandle (OD)

- Kufuneka ilingane nobubanzi be-borehole ekujoliswe kuyo (ngesiqhelo ibe nkulu kancinci kune-drill bit yokulungisa i-hole hole).

- Cinga ngokunyamezelana (± 0.1~0.5mm) ukuqinisekisa ukuchaneka kokujikeleza.

- Xa kugrunjwa ioyile, kufuneka kuhambelane nemigangatho ye-API (umz., i-API 7-1).

(2) Ubude

- Ichaphazela uzinzo—i-reamers ezinde zibonelela ngesikhokelo esingcono kodwa zinokwandisa ukungqubana.

- Uluhlu oluqhelekileyo: 200mm ~ 1500mm (kuxhomekeke kwisicelo).

(3) Inani kunye noLungiselelo lweeSika

- Ii-roller cutters ezi-3 ukuya kwezi-6 zezona zixhaphakileyo—ii-cutters ezininzi ziphucula uzinzo kodwa zinyusa imfuno ye-torque.

- Ulungiselelo lweHelical lunciphisa ukungcangcazela, lufanelekile ekubholeni imingxunya enzulu.

(4) Uhlobo loQhagamshelo (Umsonto)

- Imisonto ye-API (umz., i-NC50, i-6 5/8″ REG) yezixhobo zokugrumba ioyile.

- Uqhagamshelo olukhethekileyo (umz., IF, FH) kufuneka luhambelane nomtya wokubhola.

Amanqaku oKhetho loBukhulu obuPhambili:

✅ I-OD mayihambelane nobukhulu bequla ekujoliswe kulo, kubalwe ukuguguleka kwexesha.

✅ Umlinganiselo wobude ukuya kububanzi (L/D) uchaphazela uzinzo—ii-reamers ezinde zingcono kwimingxuma enzulu.

✅ Uqhagamshelo lwemisonto kufuneka luhambelane nomtya wokubhola ukuze kuthintelwe ukungasebenzi kakuhle komngxuma ongaphantsi komhlaba.

3. Ezinye iiParameters ezibalulekileyo

- I-RPM ephezulu:Ichaphazela ubomi bokusika—kufuneka imiselwe ngokusekelwe kwizinto ezisetyenzisiweyo kunye nokuthambisa.

-Ubushushu bokusebenza:Iindawo ezinobushushu obuphezulu (umz., imithombo enzulu) zifuna ii-alloys ezimelana nobushushu.

- Ukuhambelana kodaka/ne-coolant: Qinisekisa ukuba izinto ziyamelana nokugqwala okuvela kulwelo lokugrumba.
