Kumvetsetsa Zaukadaulo Kumbuyo kwa PDC Bits

1) Makhalidwe a PDC kubowola bits

Zithunzi za PDC amapangidwa ndi kubowola pang'ono thupi, PDC kudula mano ndi nozzles. Amagawidwa m'magulu awiri: thupi lachitsulo ndi thupi la masanjidwewo malinga ndi mapangidwe osiyanasiyana komanso njira zopangira. Thupi lonse la pobowola PDC lolimba limapangidwa ndi chitsulo chapakati cha kaboni ndikukonzedwa pogwiritsa ntchito njira zopangira makina. Boolani mabowo pamalo ogwirira ntchito pobowola ndikumangiriza mano odula a PDC ku korona wakubowola ndikumakanikiza atolankhani. Korona wa pobowola amathandizidwa ndi njira yowumitsa pamwamba (kupopera mankhwala a tungsten carbide kuvala wosanjikiza, carburizing, etc.) kuti apititse patsogolo kukana kukokoloka kwake. Ubwino waukulu wa kubowola uku ndikuti njira yopangira ndi yosavuta; kuipa kwake ndikuti thupi lobowola silingagwirizane ndi kukokoloka ndipo mano odula ndi ovuta kuwateteza, kotero sagwiritsidwa ntchito kawirikawiri. Kumtunda kwa bowolo la matrix PDC drill bit ndi thupi lachitsulo, ndipo kumunsi kwake ndi tungsten carbide wear-resistant alloy matrix, yomwe imapangidwa ndikupangidwa pogwiritsa ntchito njira yopangira zitsulo. Gwiritsani ntchito solder yotsika kutentha kuti muwotchere mano odulira a PDC kumalo osungira nyama. Tungsten carbide matrix imakhala yolimba kwambiri ndipo imalimbana ndi kukokoloka. Chifukwa chake, kubowola kwa matrix PDC kumakhala ndi moyo wautali komanso mawonekedwe apamwamba, ndipo kumagwiritsidwa ntchito kwambiri.

2) Mfundo yogwirira ntchito ya PDC kubowola pang'ono

Zobowola za PDC zimathyola miyala mwa kudula. Mano odzicheka okha amatha kudula mosavuta mu mapangidwe pansi pa mphamvu ya kubowola, ndikupita patsogolo kukameta thanthwe pansi pa mphamvu ya torque. Mano ambiri a PDC amagwira ntchito nthawi imodzi, ndipo thanthwe lomwe lili pansi pa chitsime lili ndi malo ambiri aulere, ndipo thanthwe limasweka mosavuta pansi pa shear, kotero kuti mwala wothyola mphamvu ndi wapamwamba ndipo kuthamanga kwa kubowola kuli mofulumira.

3) Kugwiritsa ntchito moyenera ma bits a PDC

Zobowola za PDC zimagwira ntchito bwino m'magawo akulu amitundu yofewa mpaka yapakati-yolimba. Osayenera kubowola zigawo za miyala ndi zofewa komanso zolimba. Pogwiritsa ntchito kuthamanga kwapansi, kuthamanga kwambiri komanso kubowola kwakukulu, kubowola kumakhala ndi zotsatira zabwino.

Chobowolacho chisanalowe mchitsime, pansi pa chitsimecho chiyenera kukhala choyera kuti pasakhale zinthu zogwa.

Chobowolacho chikatsitsidwa koyamba m'chitsime, pobowola pang'onopang'ono komanso liwiro lochepera lozungulira liyenera kugwiritsidwa ntchito pobowola, ndipo kubowola kwanthawi zonse kuyenera kuyambiranso pansi pa chitsime chitapangidwa. PDC kubowola pang'ono ndikubowola kofunikira popanda magawo aliwonse osuntha ndipo ndikoyenera kubowola kothamanga kwambiri.

Posankha azitsulo thupi PDC kubowola bits, pali zinthu zingapo zofunika kuziganizira kuti zitsimikizire kuti zikuyenda bwino. Choyamba, ndikofunikira kuwunika momwe mabowola amagwirira ntchito komanso mawonekedwe ake kuti adziwe kapangidwe koyenera kabowola ndi mawonekedwe ake. Zinthu monga mtundu wa mapangidwe, kuya kwa kubowola ndi liwiro lobowola lofunika zidzakhudza kusankha koyenera kwa chitsulo PDC kubowola pang'ono pantchitoyo.

Kuphatikiza apo, ndikofunikira kuganizira masinthidwe a zida ndi mtundu posankha zitsuloZithunzi za PDC. Kuyika ndi kukula kwa zida zodulira zimagwira ntchito yofunika kwambiri pozindikira kudulidwa bwino komanso kulimba kwa kubowola. Zida zodulira zapamwamba kwambiri pogwiritsa ntchito ukadaulo wapamwamba wa PDC zitha kusintha magwiridwe antchito onse komanso moyo wautumiki wa pobowola, ndikupangitsa kuti ikhale yopindulitsa pantchito zoboola zazitali.

Kuonjezera apo, mapangidwe a hydraulic function of drill bit sangathe kunyalanyazidwa. Dongosolo logwira mtima la hydraulic ndi lofunikira kuti zodulira zizikhala zaukhondo komanso zoziziritsa kukhosi, makamaka m'malo ovuta pobowola. Makina opangidwa bwino a hydraulic amathandizira kupewa kutsitsa pang'ono ndikuwonetsetsa Kuchotsa koyenera kwa zodulidwa, kuthandiza kukonza kubowola ndi moyo pang'ono.

Mwachidule, poganizira zofunikira pakubowola ndikusankha zida zobowola zitsulo zamtundu wa PDC zokhala ndi mapangidwe oyenera ndi mawonekedwe ake, akatswiri obowola amatha kukulitsa luso lobowola ndikupeza zotsatira zapamwamba pamapangidwe ovuta.
