Kushanda Nheyo yeRoller Bit Drilling Rig
ATricone drill bitine misoro midiki mitatu yekuboorera, imwe neimwe iine mazino akawanda akaomarara. Kana chibhorani chave kushanda, bhinzi rose rinotenderera netsvimbo yekuchera, iyo inonzi "revolution." Musoro wega wega mudiki unotendererawo paaxis yawo, zvichireva kuti roller bit ine zvese zvekuzvitenderedza uye revolution. Pamusoro pemudonzvo wekuchera, pane imwe nzira yekudzvanya iyo inoshandisa yakakosha yakatwasuka yakadzika kudzika, kazhinji makumi akati wandei ematani.
Pasi pekudzvanyirira kwakamira uku, mazino akaomarara emuchinjiziri anotsikirirwa mudombo, zvichikonzera kutsemuka kwenzvimbo. Iyo yakaoma alloy inotsikirirwa mudombo, uye roller bit inotenderera uye ichitenderera, zvichiita kuti dombo pakati pemazino riwane simba rekugera. Ichi chiito chekugera chinowedzera kukuya nekutsemura dombo. Saka, theRotary Tricone Drill Bitsshandisa ese ari maviri axial pressure uye rotational motion kupwanya dombo kuburikidza nekudzvanyirira, kugaya, uye kugera masimba, inova mechanical fracturing process.
Mufananidzo unoratidzwa ndeyemukati roller bit drilling rig, modhi KY-310. Iyo "310" inoreva dhayamita yakajairika yeTricone Drill Bityakashandiswa neirigi iyi, inova 310 mm. Iyi rig yekuchera ine zvinhu zvakasiyana-siyana senge danda rekuchera, tsvimbo yekusimudza, masilinda ekusimudza, chikuva, mashandiro ekufamba, mabheti ekuchera, majeki, masisitimu ekuchenesa guruva, uye mota inotenderera inomanikidza. Rig iyi inonzi "high-rotation" roller bit drilling rig.
Kuenzaniswa nemadhiri ekuchera, iyo yakakura mukana weiyo roller bit drilling rigs ndeye refu yekuchera tsvimbo, inogona kudarika 9 metres imwe neimwe. Netsvimbo mbiri, kureba kwese kunosvika 18 metres, iyo inokwana kumabasa mazhinji emigodhi. Nekusiyana, madhiri ezviboorwa zvema percussion rig anowanzo mapfupi, zvinoda mamwe matsinhiro ekuboora kusvika pakadzika kumwe chete, izvo zvinodzikisira kugona.
Mufananidzo uri pano unoratidza maturusi ekuchera eiyo roller bit rig, kusanganisira Milled Zino Tricone Bits. Iyo torque inoumbwa nezvikamu zvina zvikuru: tsvimbo yekuchera, tsvimbo stabilizer, shock absorber, uye roller bit, senge.Isa Zino Drill Bits.
Kunyangwe iyo rig ichiita sechinhu chimwe chete, ine zvikamu zvidiki zvakawanda, nemazino akaomarara alloy ari iwo akanyanya kunetsa. Kumashure kweiyo roller bit inewo ma alloys akaomarara, seaya anowanikwa mukati Tungsten Carbide Tricone Bits, kuvandudza kupfeka kusagadzikana. TheTCI Tricone Drill Bitsinoratidzwa mumufananidzo yakashandiswa mukuchera kwenguva yakati, uye mazino akaoma alloy akanyanya kupera. Kana mabheti aya akashandiswa kwenguva refu mune ino nyika, kuchera kuderera zvakanyanya. Mumamiriro ezvinhu akadaro, mabheti anofanira kutsiviwa, kana kuti alloys akaoma anogona kutsiviwa kuti adzorere kushanda.
Pamusoro pazvo, maburi madiki pane chibooreso chinobatana nechepakati pechibhorani chekuchera, chinopa nzira yemhepo. Pakuchera, marara ematombo anogadzirwa, uye kana asina kubviswa nenguva, bhiti rinoramba richikuya padombo, zvichideredza zvakanyanya kuchera. Izvi zvinowedzerawo kupfeka padiki uye zvinopfupisa hupenyu hwayo. Nokudaro, mweya wepamusoro-soro unofanirwa kushandiswa kudzinga marara kubva mugomba. Tsvimbo yekuchera idiki mudhayamita pane gomba, ichigadzira gap rekudzinga marara.
Nekuenderera mberi kwetekinoroji uye kuvandudzwa kwehunyanzvi hwekuchera migodhi, ma roller bit drilling rigs, kunyanya ayo anoshandisa.Hard Rock Tricone BitsuyeMvura Mutsime Tricone Bits, inosungirwa kushanduka kuita michina inoshanda zvakanyanya, ine hungwaru, uye inochengetedza zvakatipoteredza. Tinotenda izvozvoSoft Rock Tricone Bitsuye humwe hutsva huchaita basa rakatonyanya kukosha mumabasa emugodhi mune ramangwana, zvichizotungamira kune zvinotoshamisa kubudirira.
