Ndeupi musiyano uripo pakati pesimbi muviri uye matrix muviri PDC bit

PDC drill bit inogadzirwa zvakanyanya nePDC cutters uye simbi, ichibatanidza kunaka kusimba kusimba kwesimbi uye kupfeka-kupokana kwepolycrystalline diamond compact inoita kuti PDC ive nekukurumidza tsoka mukuchera. Muviri wesimbi PDC bit ine kukurumidza kukurumidza mukuumbwa kwakapfava nepo matrix muviri PDC diki ichinyanya kupikisa kupfeka, matrix body bit inogona kudhiraivha yakaoma kana ichienzaniswa nesimbi muviri PDC bit nekuda kwetungsten carbide matrix body, asi ine zvishoma zvishoma zvichienzaniswa nesimbi muviri PDC drill bit.

Matrix Body PDC Bits vs. Steel Body PDC Bits

Kana iwe wakashanda mukuchera chero nguva yenguva, iwe wakambonzwa nezvePDC bits. PDC inomirira "polycrystalline diamond compact," inotsanangura musanganiswa wezvinhu unoumba mabits' aya ekucheka nzvimbo. Ose Matrix Body PDC uye Steel Body PDC anogadzirwa neiyi komboni.

Mabhii aya anoenda nemazita akawanda. Vanowanzonzi:

• PDC Bits
• Polycrystalline diamond compact bits
• Composite chip mazino bits
• Polycrystalline diamond yekucheka block bits

PDC bits anowanzo shandiswa pakuchera oiri - asi anozivikanwa mune mamwe maindasitiri zvakare. Ivo vakagadzirwa muna 1976 uye vakangofarirwa iye zvinoroller-cone bits(rudzi rwebhiti rine zvikamu zvinotenderera). Nepo maPDC mabhiti aine nhoroondo refu yekubudirira, anoramba achishanduka uye anogara achivandudza kuburikidza neatsva uye matsva ekucheka makona, kuronga, uye zvinhu. Aya mabheti anoshanda zvakanyanya sezvo achishanda kugera maumbirwo ematombo pane kuapwanya. Gore rega rega, kufambira mberi kutsva mune tekinoroji kunovandudza kushanda kwePDC bits uye kunatsiridza kumhanya kwekuchera.

Aya mabhiti anozivikanwa se "nose-to-the-grindstone" mabhiti eindasitiri yekuchera - anoita kuti basa riitwe uye anogona kushanda zvakanyanya kune akasiyana siyana masevhisi nemhando dzekugadzira-hapana zvidimbu zvinofamba kuti zviputike, kwete. kukakavara, kungochera kunoshanda kune zvese zvaunoda.

Chii chinonzi PDC Bits?

Kune maviri ekutanga masitaera ePDC drill bits- matrix muviri PDC mabheti uye simbi muviri PDC mabheti. Ose ari maviri akafanana akaumbwa mabheti akatenderera ane mana kusvika masere ekucheka zvimiro, kana mablades, anofefetera kubva pakati. Chipande chega chega chinozoiswa pakati pevatema gumi kusvika makumi matatu. Mabhiti ane migero yemvura yakaparadzirwa kuti itonhodze, uye pane muromo wemuromo wepamusoro pebhiti. Kana iwe uri kuyedza kufungidzira zvishoma izvi, zvinotaridzika senge korona ingapfekwa namambo.

PDC mabits anoshandiswa kuchera oiri negasi, kuchera geothermal, kuchera matsime emvura, kuchera kuvaka, kuchera uye kuchera kwakatwasuka.

Iyo Sainzi Kuseri kwePDC Bits

Ungave wakadzidza kuchikoro kuti dhaimani chinhu chakaoma zvikurusa chinozivikanwa nomunhu. Zviri! Uye yakanakira kucheka kuburikidza nezvimwe zvinhu zvakaita sematombo maumbirwo ekuchera.

PDC mabheti anoshandisa madhaimani madiki, asingadhure, akagadzirwa nevanhu muzvimiro zvavo zvekucheka. Nzira yekugadzira madhaimondi pazvimedu izvi yakaoma. Yakarerutswa, heino maitiro ekugadzira madhaimondi eku drill bits:

• Madhaimani madiki ekugadzira anogadzirwa
• Madhaimani anobva aunganidzwa kuita makristasi makuru
• Makristasi acho anobva aumbwa kuita matafura edhaimani
• Matafura edhaimani anobva asungirirwa kusimbi, kazhinji tungsten carbide, uye simbi inosunga
• Ichi chinova chikamu chekucheka chebhiti - kune vakawanda vanocheka pane imwe neimwe blade yebhiti
• Vanocheka vanobva vasungirirwa kune mashizha, ayo akabatanidzwa nemuviri webhiti

Pamwe chete, vanocheka uye mashizha pamucheto wePDC bit anoshandiswa kucheka kuburikidza nematombo emhando dzemarudzi ose.

Synthetic Diamonds muDrill Bits

Sezvauri kuona, madhaimani ekugadzira ndiwo akakosha zvinhu zvePDC bits. Mukugadzira mabits aya, ma-ultra-diki tsanga dzedhaimondi (inonziwo diamond grit) inogadzirwa. Iyi grit inogara yakasimba asi inova isina kugadzikana pa molecular level kana yapisa. Saka, yako PDC bit ingangokundikana kana isina kunyatsotonhodzwa kana ichishandiswa.

Zvisineyi, madhaimani ekugadzira haagone kupfeka; iwo ndiwo akakodzera zvinhu zvehupenyu hurefu uye kusimba. Mhando yesimbi inoshanduka kana ukasarudza matrix kana simbi yemuviri bhiti - asi dhaimondi rakakosha. PDC bits inogona kuva nehupenyu hurefu chero bedzi ichinyatsotonhorera.
