Kodi pali kusiyana kotani pakati pa thupi lachitsulo ndi matrix body PDC bit

Kubowola kwa PDC kumapangidwa makamaka ndi odula a PDC ndi chitsulo, kuphatikiza kulimba kwachitsulo komanso kusamva kukana kwa polycrystalline diamondi yaying'ono kumapangitsa kuti PDC ikhale ndi zithunzi mwachangu pobowola. Thupi lachitsulo PDC limakhala ndi liwiro lothamanga pamapangidwe ofewa pomwe matrix body PDC bit ndi odana ndi kuvala osamva, matrix body bit amatha kubowola molimba poyerekeza ndi chitsulo cha PDC bit chifukwa cha tungsten carbide matrix body, koma imakhala yocheperako poyerekeza ndi zitsulo thupi PDC kubowola pang'ono. Ngati mukufuna chilichonse mwazinthu za PDC, pls lumikizanani ndi Far Eastern Drilling

Matrix Body PDC Bits vs. Steel Body PDC Bits

Ngati mwagwira ntchito pobowola nthawi iliyonse, mwina mwamvapo za PDC bits. PDC imayimira "polycrystalline diamond compact," yomwe imatanthawuza zakuthupi zomwe zimapanga malo odulidwawa. Matrix Body PDC ndi Steel Body PDC amapangidwa ndi gululi.

Zidutswa izi zimapita ndi mayina ambiri. Nthawi zambiri amatchedwa:

• Zithunzi za PDC
• Zojambula za diamondi za polycrystalline
• Zosakaniza za chip mano
• Zojambula za diamondi za polycrystalline

PDC bits amagwiritsidwa ntchito pobowola mafuta - koma amadziwikanso m'mafakitale ena. Iwo analengedwa mu 1976 ndipo ndi otchuka monga tsopanozidutswa za roller-cone(mtundu wa kanyama kakang'ono kamene kamakhala ndi mbali zozungulira). Ngakhale ma PDC ali ndi mbiri yakale yopambana, akupitiliza kusinthika ndikusintha mosalekeza kudzera m'makona, makonzedwe, ndi zida zatsopano komanso zatsopano. Tizidutswa tating'onoting'ono timeneti timagwira ntchito bwino pakumeta miyala yomwe idapangidwa m'malo moiphwanya. Chaka chilichonse, kupita patsogolo kwatsopano kwaukadaulo kumathandizira magwiridwe antchito a PDC bits ndikuwongolera liwiro loboola.

Tizidutswa tating'onoting'ono timeneti timadziwika kuti "mphuno-to-grindstone" pamakampani obowola - amatha kugwira ntchitoyo ndipo amatha kukhala othandiza kwambiri pamitundu yosiyanasiyana ya mautumiki ndi mapangidwe - palibe magawo osuntha kuti atseke, ayi. kukangana, kubowola kothandiza pazosowa zanu zonse.

Kodi PDC Bits Ndi Chiyani?

Pali mitundu iwiri yoyambirira yaZithunzi za PDC- matrix body PDC bits ndi zitsulo thupi PDC bits. Onsewo ali ndi tizidutswa tating'ono tating'ono tomwe timakhala ndi timiyala todulira tinayi mpaka 8, kapena masamba, omwe amakupiza kuchokera pakati. Tsamba lililonse limakhala ndi zodula pakati pa khumi ndi makumi atatu. Tizigawo timene timatulutsa timadzi timene timamwazikana kuti tizizizirira, ndipo pansonga pake pali pobowola. Ngati mukuyesera kulingalira pang'ono izi, zikuwoneka ngati korona yomwe mfumu ingavale.

Mabotolo a PDC amagwiritsidwa ntchito pobowola mafuta ndi gasi, kubowola m'nthaka, kubowola chitsime chamadzi, kubowola zomangamanga, migodi ndi kubowola kopingasa.

Sayansi Pambuyo pa PDC Bits

Mwina munaphunzira kusukulu kuti diamondi ndi chinthu chovuta kwambiri chodziwika kwa munthu. Zili choncho! Ndipo ndi yabwino kudulira zida zina monga miyala yoboola.

PDC bits amagwiritsa ntchito diamondi zazing'ono, zotsika mtengo, zopangidwa ndi anthu m'mapangidwe awo odula. Njira yopangira diamondi pazigawozi ndizovuta. Mwachidule, nayi njira yopangira ma diamondi kubowola:

• Ma diamondi ang'onoang'ono opangidwa amapangidwa
• Kenako diamondizo amaziphatikiza kukhala milu ikuluikulu ya makhiristo
• Makristalowo amapangidwa kukhala matebulo a diamondi
• Matebulo a diamondi amamangiriridwa kuchitsulo, nthawi zambiri tungsten carbide, ndi zitsulo zomangira
• Izi zimakhala gawo lodula la pang'ono - pali ocheka ambiri pa tsamba lililonse la pang'ono
• Odulawo amamangiriridwa ku masambawo, omwe amamangiriridwa ku thupi la pang'ono

Pamodzi, ocheka ndi masamba pansonga ya PDC bit amagwiritsidwa ntchito kudula miyala yamitundu yonse.

Ma diamondi Opangidwa mu Drill Bits

Monga mukuonera, ma diamondi opangidwa ndi zinthu zofunika kwambiri pa ma PDC bits. Popanga zitsulozi, njere zazing'ono kwambiri za diamondi (zomwe zimatchedwanso diamondi grit) zimapangidwa. Grit iyi ndi yolimba kwambiri koma imakhala yosakhazikika pamlingo wa molekyulu ikatentha. Chifukwa chake, pang'ono yanu ya PDC imatha kulephera ngati siyinaziziritsidwe mokwanira ikagwiritsidwa ntchito.

Mosasamala kanthu, ma diamondi opangidwa amakhala osamva kuvala; iwo ndi zinthu zabwino kwa moyo wautali ndi durability. Mtundu wachitsulo umasintha ngati mutasankha matrix kapena zitsulo thupi - koma diamondi ndi yofunika kwambiri. Ma bits a PDC amatha kukhala ndi moyo wautali bola atakhazikika mokwanira.
