Mitundu yosiyanasiyana ya odula a PDC
Mitundu yosiyanasiyana ya odula a PDC
Kubowola ndi ntchito yofunika kwambiri pamakampani amafuta ndi gasi. PDC bits (omwe amatchedwanso Polycrystalline Diamond Compact bit) amagwiritsidwa ntchito pobowola. PDC bit ndi mtundu wa kachidutswa kakang'ono kamene kamakhala ndi odula angapo a Polycrystalline Diamond (PCD) omwe amamangiriridwa ku thupi laling'ono ndikudula miyala mwa kumeta ubweya pakati pa odula ndi thanthwe.
PDC cutter ndi gawo lofunikira kwambiri pakubowola pang'ono, komanso kavalo wobowola. Mawonekedwe osiyanasiyana a PDC cutter amapangidwa kuti akwaniritse ntchito zosiyanasiyana. Kusankha mawonekedwe oyenera ndikofunikira kwambiri, zomwe zimatha kuwongolera magwiridwe antchito ndikuchepetsa mtengo wobowola.
Nthawi zambiri, timagawaniza chodula cha PDC motere:
1. PDC flat cutters
2. Mabatani a PDC
PDC flat cutters amagwiritsidwa ntchito kwambiri pobowola migodi m'minda yamafuta ndi migodi. Itha kugwiritsidwanso ntchito mu diamondi core bit ndi PDC yonyamula.
Ubwino Wachikulu kwa ocheka a PDC:
• Kuchulukana kwakukulu (kutsika pang'ono)
• High compositional & structural homogeneity
• Kuvala kwakukulu ndi kukana mphamvu
• Kukhazikika kwapamwamba kwa kutentha
• Kuchita bwino kwambiri komwe kulipo pamsika
PDC lathyathyathya wodula awiri osiyanasiyana kuyambira 8 mpaka 19mm ::
Zomwe zili pamwambazi ndizomwe ogwiritsa ntchito angasankhe. Nthawi yomweyo, mitundu yosiyanasiyana yazinthu imatha kupangidwa ndikusinthidwa malinga ndi zomwe ogwiritsa ntchito amafuna.
Monga lamulo, odula akuluakulu (19mm mpaka 25mm) amakhala ankhanza kuposa odula ang'onoang'ono. Komabe, iwo akhoza kuwonjezera kusinthasintha kwa torque.
Odula ang'onoang'ono (8mm, 10mm, 13mm ndi 16mm) awonetsedwa kuti amabowola pamlingo wokwera kwambiri (ROP) kuposa ocheka akuluakulu pamapulogalamu ena. Ntchito imodzi yotereyi ndi miyala yamchere mwachitsanzo. Ma Bits amapangidwa ndi ocheka ang'onoang'ono koma ambiri amatha kupirira kutsitsa kwakukulu.
Kuphatikiza apo, odula ang'onoang'ono amatulutsa tizidutswa ting'onoting'ono pomwe odula akulu amatulutsa zazikulu. Kudula kwakukulu kumatha kuyambitsa zovuta pakuyeretsa dzenje ngati madzi akubowola sangathe kunyamula zodulidwazo.
Zithunzi za PDC
Kunyamula kwa PDC kumagwiritsidwa ntchito ngati chotchingira chotchinga chamoto chotsitsa pansi, chomwe chimagwiritsidwa ntchito kwambiri m'makampani opangira mafuta ndi mafakitale apansi otsika. PDC yonyamula ili ndi mitundu yosiyanasiyana kuphatikiza PDC yotulutsa ma radial, PDC thrust kubala.
Zovala za PDC ndizolimba kwambiri kuvala. Poyerekeza ndi chikhalidwe cha tungsten carbide kapena zitsulo zolimba za alloy, moyo wa diamondi ndi nthawi 4 mpaka 10, ndipo amatha kugwira ntchito pa kutentha kwakukulu (pakali pano kutentha kwakukulu ndi 233 ° C). Dongosolo lonyamulira la PDC limatha kuyamwa katundu wochulukirapo kwa nthawi yayitali, ndipo kutayika kocheperako pagulu lonyamula kumawonjezera mphamvu zamakina.
Mabatani a PDC amagwiritsidwa ntchito kwambiri pobowola pang'ono DTH, cone bit, ndi diamondi kusankha.
Zosankha za diamondi zimagwiritsidwa ntchito kwambiri pamakina amigodi, monga ng'oma zochulukira migodi, ng'oma za Longwall shearer, makina oboola ngalande (makina a chishango, makina obowola mozungulira, tunnel, ng'oma zamakina, ndi zina zotero)
Mabatani a PDC makamaka akuphatikizapo:
(1) Mabatani a PDC: omwe amagwiritsidwa ntchito makamaka pakubowola kwa DTH.
(2) PDC conical mabatani: makamaka ntchito kondomu pang'ono.
(3) PDC parabolic mabatani: makamaka ntchito kudula wothandiza.
Poyerekeza ndi mabatani a tungsten carbide, mabatani a PDC amatha kusintha kukana kwa abrasive nthawi zopitilira 10.
Mabatani okhala ndi PDC
PDC conical cutters
PDC parabolic mabatani
Kupatula kukula kwake, titha kupanganso zojambula zanu.
Takulandilani kuti mupeze zodula za zzbetter PDC, magwiridwe antchito apamwamba, mtundu wosasinthika, komanso mtengo wapamwamba kwambiri.
