Iingxaki ezine ezingundoqo zokonakala kweBit

Zininzi izizathu zokonakaliswa kwe-core drill, ingakumbi ukubandakanya amazinyo aphukileyo, iipakethi zodaka, umhlwa, umlomo okanye ukuvaleka kwetshaneli, umonakalo ojikeleze umbhobho kunye nawo ngokwawo, njl.

 

Ingxaki yamazinyo eyophukileyo yeCoring bit:

 

I-core drill bit ithwala imithwalo eyahlukeneyo etshintshanayo ngexesha lenkqubo yokomba, ekhokelela ngokuthe ngqo kumazinyo aphukileyo.Kwangaxeshanye, amasuntswana angundoqo nawo axhomekeke kwimisinga yeeddy, ukusika amatye, ukusila kunye nokhukuliseko lodaka.Nangona ezi nzakala zingakhokeli kumazinyo aphukileyo kumanqanaba okuqala, zihlala ziphela ngamazinyo aphukileyo.

 

Ingxaki yengxowa yodaka yeCoring bit:

 

Into ebizwa ngokuba yi-drilling ingxowa yodaka ithetha ukuba ngexesha lokugaya, amandla okusika ilitye likhulu kakhulu, kwaye amanzi akhutshwe kwilitye le-metaplastic, okwenza ukuba i-rock cuttings ibambelele kumzimba we-drill.Ukuba i-cuttings ayisuswanga ngexesha, iya kuqokelela ngakumbi nangaphezulu, okubangela imigodi yodaka.Iingxaki ze-Mudbag zinokuba nefuthe elibi kakhulu kwiibhithi eziphambili kwaye zidla ngokubangela iingxaki ezimbini:

 

I-1.I-core drill bit iqokelela inani elikhulu lokusika, kwaye amazinyo okusika akakwazi ukuchukumisa ukubunjwa, okubangelwa ukuhla kwesantya sokugaya oomatshini:

 

I-2.I-coring bit iqokelela inani elikhulu le-viscous cuttings, eyenza ukuba isebenze njengepiston yetanki yamafutha ukuze ithathe uxinzelelo kwi-shaft xa uxinzelelo luguquguquka kakhulu;

 

Ingxaki yangoku yeCoring bit eddy:

 

Ibhithi engundoqo ityhalelwa eludongeni lwequla phantsi kwentshukumo yobunzulu bokungalingani kwecala, kwaye elinye icala lebit engundoqo likhuhla eludongeni lomthombo.Xa idayimani ishukuma ngokungaqhelekanga, iziko layo lokujikeleza elikhawulezileyo aliseloziko lejometri yedayimani.Imeko yentshukumo ngeli xesha ibizwa ngokuba yi-eddy current.Emva kokuba i-vortex idaliwe, kunzima ukuyeka.Kwangaxeshanye, ngenxa yesantya esiphezulu, intshukumo yombindi wesuntswana ivelisa amandla amakhulu e-centrifugal, kwaye elinye icala le-core bit lityhalelwa eludongeni lomthombo, oluvelisa amandla amakhulu okukhuhlana, ngaloo ndlela kuphuculwa amandla ombane. i-core bit kwaye ekugqibeleni ibangele umonakalo kwi-core bit;

 

Imiba yomonakalo weJet Bounce:

 

Kwinqanaba lokuqala le-core bit, ngenxa yoyilo olungekho ngqiqweni lwe-hydraulic, ukuhamba kwejethi ezantsi komngxuma kukhulu kakhulu, inxalenye yayo eyenza i-diffuse flow, kwaye inxalenye iphinda ibuyele kumphezulu we-core bit.Ijethi enesantya esiphezulu ikhukulisa ngokuthe ngqo icore bit, kuqala konakalisa indawo ephakathi ye-core bit, kwaye ekugqibeleni yonakalise yonke i-core bit.
