Vhurai Chakavanzika cheKurebesa Drill Bit Hupenyu uye Nekukurumidza Kuchera!

1. Kusarudza Mhando Yezino Yakakodzera yeRoller Cone Drill Bits

Kusarudza rudzi rwezino rwakakodzeraroller cone drill bitshaingowedzeri hupenyu hwesevhisi chete asi zvakare inovandudza mitengo yekupinda uye inoderedza mitengo yekuchera. Sarudzo yerudzi rwezino inonyanya kuenderana nechimiro chedombo uye michina yedombo, kusanganisira simba rayo rekumanikidza, kuoma, uye kudhiraivha. Pamusoro pezvo, zvinhu zvakaita sechibhorani dhayamita, zvemukati memvura, uye tekinoroji kuita kwechibhorani chinofanirwa kutariswa:

① Yekuumbwa kwedombo rakaoma:

Ball-tooth drill bits inowanzoshandiswa. Aya mabheti ane mazino mapfupi uye akatsimba, anogona kumirisana nepamusoro axial pressure, ichiita kuti aenderane nekuboora mumatombo akaomarara uye anopwanya.

② Yekuumbwa kwedombo rakapfava:

Wedge-tooth drill bits anowanzo shandiswa. Aya mabheti ane mazino akareba uye akapfupika, zvichiita kuti ave akanakira kuchera mune akapfava kana epurasitiki dombo.

Kusarudzwa kusina kunaka pakati pemhando mbiri idzi kunogona kutungamirira kune kusakosha. Kushandisa bhora-mazino mabheti mudombo rakapfava kunogona kukonzera hupenyu hurefu asi kuderera kwakanyanya kwekupinda, izvo zvinotungamira kukwirisa kwese kwemitengo yekuchera. Sezvineiwo, kushandisa wedge-zino mabheti mune yakanyanya kuoma, abrasive dombo inogona kuita kuti mazino alloy asakara kana kutsemuka nekukurumidza. Naizvozvo, kusarudza rudzi rwezino rakakodzera kunowedzera kuita zvishoma uye hupenyu hurefu.

2. Kunatsiridza Drilling Parameters

Kupinda kwechibhorani kunokanganiswa nezvinhu zvakawanda, zvinosanganisira chimiro chedombo uye mashandiro edombo, axial pressure inoshandiswa pabhiti, kumhanya kwekutenderera kwechibhorani, torque yebhiti, dhizaini yemazino, huwandu hwemazino ari kubata dombo, uye huwandu hwemhepo yakatsikirirwa inoshandiswa pakuchenesa chibhorani. Pakati peizvi, iwo akakosha maparamita anotaridza kudhirowa kweaxial pressure, kutenderera kumhanyisa, uye kuyerera kwemhepo yekubvisa kucheka:

①Axial Pressure uye Bit Hupenyu:

Yakakwana axial pressure yakakosha kuti inyatsopwanya dombo, sezvo richifanira kuunza kushushikana kwakakwana kukunda simba rekumanikidza redombo. Nekudaro, kune yakaringana huwandu hweaxial pressure. Kunyanya kudzvanya kupfuura iyi chiyero hakuzo wedzera mwero wekupinda uye kunogona kukonzera kupera nguva isati yakwana kana kukuvadzwa kwemabhengi ebhiti kana mazino ecarbide.

② Kutenderera Kumhanya:

Mukati mehumwe uwandu, mwero wekupinda unowedzera nekumhanya kwekutenderera. Nekudaro, kumhanya kwakanyanya kunogona kuita kuti zviome kubvisa zvicherwa kubva muchibhorani, zvichikonzera kuputika kwedombo kwechipiri uye kuzunguzika kwakasimba, izvo zvinopfupisa hupenyu hushoma. Optimal kumhanya inovimbisa yakakwana nguva yekubatana pakati pemazino nedombo kuti ibudirire kuputika kwevhoriyamu. Kune matombo akaomarara, kukurumidza kutenderera kwepamusoro kunorambidzwa nekuda kwekuwedzera kwekuita mitoro, iyo inomhanyisa kupfeka pameno nemabhengi. Sezvineiwo, mudombo rakapfava, yakakwira-speed, yakaderera-kudzvanywa nzira inowanzoshanda.

③ Kuyerera Kwemhepo uye Kubviswa Kwekucheka:

Huwandu hwekuyerera kwemhepo hunokanganisa zvakananga kuita zvishoma. Kuwedzera kuyerera kwemhepo kunochenesa chibhorani, kunonatsiridza mamiriro ekuchera, kunoderedza kupera kwemazino, uye kunopa kutonhora kuri nani kwemabheyiri, zvichibva zvawedzera hupenyu hushoma. Nekudaro, kucheneswa kwechibhorani kunotsamira kwete chete pakuyerera kwemhepo asiwo neanular nzvimbo pakati pepombi yekuchera nemadziro echibhorani, iyo inotaridza kudzoka kwemhepo. Kugadziridza kubviswa kwekucheka kunoda kuenzanisa compressor simba uye kuderedza kusingakoshi kushandiswa kwemhepo.

④ Kuvandudza Unyanzvi hweMushandi:

Maoperator anofanirwa kugadzirisa axial pressure uye kutenderera kumhanya zvinoenderana nekuchinja kwematombo kuti aenderane nemamiriro ekuchera, nekudaro kudzivirira kusaenzana kwebhiti kupfeka. Mukuwedzera, ivo vanofanira kutevedzera mitemo yekushanda:

- Ita shuwa kuti chibhorani chakachena uye hachina zvinhu zvekunze usati wachera.

- Chengetedza rig yakagadzikana uye shandisa kumhanya kuri pakati nepakati paunotanga chibhorani kudzivirira kutsauka, izvo zvinogona kuderedza hupenyu hushoma.

- Nyorera yakaderera axial kudzvanywa kwekutanga kune mabits matsva, uchibvumira kumhanyisa-munguva, usati wawedzera kune akajairwa mazinga.

- Gara uchipa mhepo yakakwana yekubviswa kwekucheka panguva yese yekuchera, kunyangwe kana uchibvisa chidimbu kubva mugomba.

- Pazvibhorani zvakanyorova kana pakushandisa guruva remvura-yemvura, sarudza mabhiti ane mabhomba akakodzera kuti uwedzere mhepo yemuno, kudzivirira bhiti.

- Gara uchiongorora bit mushure mekuchera. Kupisa kusina kuenzana mumakoni kunogona kuratidza nzira dzakavharwa dzekutonhodza, dzinofanira kucheneswa nekukasika.

-Nzvenga kushandisa mapaipi ekubooresa akabhenda, sezvo achigadzira mitoro isina kuenzana, ichikonzera kupfeka kwenzvimbo uye kukuvadzwa kudiki.

- Dzivirira kukanganisa kwekushanda kudzivirira kudonhedza mabhiti muchibhorani kana kuzviisa pamitoro inongoerekana yaitika.

- Kana kuchera kwambomira, tenderedza makoni nemaoko uye ufuridze marara kuti uve nechokwadi chekutangisazve kushanda.

-Shandisa stabilizer pamusoro peiyo bit kuti uchengetedze kurongeka kwechibhorani, kuderedza kuzunguzika, uye kugadzirisa bhiti kuita.

Mastabilizer anobatsira pakati peiyo bhiti, kudzivirira kutsauka kwechibhorani, uye kuderedza kuzunguzika, zvichikonzera kushanda kwakapfava, kudzikiswa kwemazino, uye hupenyu hwakawedzerwa kune ese ari maviri uye zvikamu zvawo. Mabhiti ane alloy anoisa zvakare anowedzera kupfeka kuramba, kudzivirira kupera nguva isati yakwana pamapedhi anodzikamisa uye kuwedzera zvakanyanya kugadzikana uye kusimba.
