I-Thermal Effect ku-PDC Cutter

Bekwaziwa ukuthi izingcezu ze-PDC zisebenza kahle kakhulu kunezingqimba zama-roller cone, kodwa lokhu ngokwesiko kubonakala kuphela ngenkathi kubholwa amatshe athambile. Lokhu kungase kube ngenxa yokuthi u-50% wamandla okubhola angachithwa ngumsiki ogugile. Ngaphezu kokugqokwa okubangelwa ukusebenzisana phakathi kwedwala nomsiki, imiphumela yokushisa ingasheshisa izinga umsiki azogqoka ngalo.

Uma imiphumela yokushisa ibinganakiwe, bekungabangela ukuthi ukuguga kwebhithi kube wumsebenzi womthwalo ofakwe kancane kanye nebanga elihanjiwe ngenkathi uthintana netshe. Njengoba sazi, akunjalo. Imiphumela yokushisa inomthelela esilinganisweni okugqoka ngaso amabhithi.

Kuthiwa ukuguga kwensimbi kuhlobene nobulukhuni bezinto eziqhumayo kanye nensimbi. Kuma-abrasive athambile anesilinganiso esingaphansi kuka-1.2, isilinganiso sokugqoka siphansi. Njengoba isilinganiso sobunzima obuhlobene budlula u-1.2, izinga lokugqoka likhuphuka kakhulu.

Uma ubheka i-quartz, esukela ku-20- 40% wokwakheka kwamatshe amaningi, ubulukhuni buphakathi kuka-9.8-11.3GPa kanye nobe-tungsten carbide yi-10-15GPa. Lobu bubanzi buphumela esilinganisweni esisuka ku-0.65 siye ku-1.13, sihlukanisa lobu budlelwano njengento elimazayo ethambile. Uma i-tungsten carbide isetshenziselwa ukusika amatshe ku-350 oC noma ngaphansi, ahlangabezana nezinga lokuguga elifana nele-abrasive ethambile njengoba kulindelekile.

Uma izinga lokushisa lingaphezu kuka-350 oC, ukuguga kuyasheshiswa futhi kuhlotshaniswa kangcono naleyo ye-abrasive eqinile. Kulokhu, kuphetha ngokuthi ukugqoka kukhuphuka ngomphumela oshisayo. Ukunciphisa ukugqokwa kwe-PDC, kungaba kuhle ukulawula izinga lokushisa labasiki.

Ngenkathi ucwaningo lwemiphumela eshisayo ekugqokeni kwe-PDC luqala, i-750oC kwakuyizinga lokushisa eliphezulu eliphephile lokusebenza. Lokhu kushisa kwasungulwa, ngoba ngaphansi kwalokhu kushisa kwe-microchipping kwakuyimpahla ebonakala kusisiki.

Ngaphezu kuka-750 ℃ ​​izinhlamvu zedayimane ezigcwele zazikhishwa ongqimbeni lwedayimane futhi lapho zifinyelela emazingeni okushisa angaphezu kuka-950 ℃ i-tungsten carbide stud yaba nokonakala kwepulasitiki. Ukuqonda kwabasiki kanye ne-PDC bit geometry kumele kucace ukuze kunikeze ulwazi olwanele lapho ukhetha kancane.

I-Zzbetter ihlinzeka ngesisiki se-PDC sekhwalithi ephezulu esinokuzinza okuhle kwe-thermal. Ithimba lethu lisebenza kanzima kakhulu ukwenza imikhiqizo esezingeni. Sibheke ngabomvu ukukhonza ibhizinisi lakho.

Uma unentshisekelo kubasiki be-PDC futhi ufuna ulwazi olwengeziwe kanye nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE I-IMEYILI ezansi nekhasi.
