Izinkinga Ezine Ezinkulu Zokulimala Kwe-Core Bit

Kunezizathu eziningi zokulimala kokubhoboza okuyisisekelo, ikakhulukazi okuhlanganisa amazinyo aphukile, amaphakethe odaka, ukugqwala, umlomo wombhobho noma ukuvaleka kwesiteshi, umonakalo ozungeze umlomo wombhobho kanye ngokwawo, njll. Namuhla, ake sihlaziye umgebengu ngokuningiliziwe wokubhola okubalulekile:

 

Inkinga yezinyo eliphukile i-Coring bit:

 

I-core drill bit ithwala imithwalo ehlukahlukene eshintshanayo phakathi nenqubo yokumba, okuholela ngokuqondile emazinyweni aphukile.Ngesikhathi esifanayo, ama-core bits nawo angaphansi kokugeleza kwamanzi, ukusika amatshe, ukugaya kanye nokuguguleka kodaka.Nakuba lokhu kulimala kungaholeli emazinyweni aphukile ekuqaleni, ngokuvamile amazinyo aphukile.

 

Inkinga yesikhwama sodaka se-Coring bit:

 

Okubizwa ngokuthi isikhwama sodaka sokumba kusho ukuthi phakathi nenqubo yokumba, amandla okusika amadwala makhulu kakhulu, futhi amanzi aphuma edwaleni le-metaplastic, okwenza ukuthi ama-rock cuttings abambelele emzimbeni wokubhoboza.Uma ama-cuttings engasuswa ngesikhathi, azonqwabelana kakhulu, okuholela emigodini yodaka.Izinkinga ze-Mudbag zingaba nomthelela omubi kakhulu kuma-core bits futhi zivame ukudala izinkinga ezimbili:

 

I-1.I-core drill bit iqoqa inani elikhulu lokusikwa, futhi amazinyo okusika awakwazi ukuthinta ukwakheka, okuholela ekwehleni kwesivinini sokumba ngomshini:

 

I-2.I-coring bit iqoqa inani elikhulu lokusikwa kwe-viscous, okwenza kube njengepiston yethangi likaphethiloli ukuze ibambe ukucindezela ku-shaft lapho ingcindezi iguquguquka kakhulu;

 

Inkinga yamanje ye-Coring bit eddy:

 

I-core bit iphushwa odongeni lomthombo ngaphansi kwesenzo sokungalingani kwe-lateral okujulile, futhi uhlangothi olulodwa lwe-core bit luhlikihla odongeni lomthombo.Lapho idayimane linyakaza ngendlela engavamile, isikhungo salo sokuzungeza ngokushesha asiseyona isikhungo sejometri sedayimane.Isimo sokunyakaza ngalesi sikhathi sibizwa ngokuthi i-eddy current.Uma i-vortex idaliwe, kunzima ukuyimisa.Ngesikhathi esifanayo, ngenxa yejubane eliphezulu, ukunyakaza kwe-core bit kukhiqiza amandla amakhulu e-centrifugal, futhi uhlangothi olulodwa lwe-core bit lududulelwa odongeni lomthombo, olukhiqiza amandla amakhulu okungqubuzana, ngaleyo ndlela kuthuthukiswe amandla e-eddy current. i-core bit futhi ekugcineni ibangele ukulimala kwe-core bit;

 

Izinkinga Zokulimala Kwe-Jet Bounce:

 

Esigabeni sokuqala se-core bit, ngenxa yedizayini ye-hydraulic engenangqondo, ukugeleza kwejethi phansi kwembobo kukhulu kakhulu, ingxenye yayo eyakha ukugeleza okusabalalisayo, futhi ingxenye iphindela ebusweni be-core bit.I-jet enesivinini esikhulu iguguleka ngokuqondilecore bit, okokuqala kulimaze ingxenye emaphakathi ye-core bit, futhi ekugcineni kulimaze yonke ingxenye ewumgogodla.
