Muhimman Kayan Raw Biyu na Yankan PDC

Abun yankan PDC wani nau'in abu ne mai wuyar gaske wanda ke haɗa lu'u-lu'u na polycrystalline tare da matsi na tungsten carbide a matsanancin zafin jiki da matsa lamba.

General Electric (GE) ne ya fara ƙirƙira PDC Cutter da farko a cikin 1971. Na farko PDC Cutters don masana'antar mai da iskar gas an yi shi a cikin 1973 kuma bayan shekaru 3 na gwaji da gwajin filin, an tabbatar da su da inganci fiye da murkushe ayyukan carbide. Button bits don haka an gabatar da su ta kasuwanci a cikin 1976.

PDC Cutters an yi su daga tungsten carbide substrate da grit na lu'u-lu'u na roba. Lu'u-lu'u da ma'auni na carbide suna girma tare ta hanyar haɗin sinadarai a ƙarƙashin yanayin zafi da matsanancin matsa lamba.

Abubuwan da suka fi mahimmanci na masu yankan PDC sune lu'u lu'u lu'u-lu'u da ma'aunin carbide.

1. Gishiri na Diamond

Gilashin lu'u-lu'u shine mabuɗin albarkatun ƙasa don masu yankan PDC. Dangane da sinadarai da kaddarorin, lu'u-lu'u da aka yi da mutum yayi kama da lu'u-lu'u na halitta. Yin grit lu'u-lu'u ya ƙunshi tsari mai sauƙi na sinadarai: carbon na yau da kullun yana dumama ƙarƙashin matsanancin matsi da zafin jiki. A aikace, duk da haka, yin lu'u-lu'u yana da nisa daga sauƙi.

Gilashin lu'u-lu'u ba shi da kwanciyar hankali a babban yanayin zafi fiye da lu'u-lu'u na halitta, duk da haka. Saboda mai kara kuzari da aka makale a cikin tsarin grit yana da ƙimar haɓakar zafi sama da lu'u-lu'u, haɓaka daban-daban yana sanya haɗin lu'u-lu'u zuwa lu'u-lu'u a ƙarƙashin ƙarfi kuma, idan lodi ya isa sosai, yana haifar da gazawar shaidu. Idan shaidu sun kasa, lu'u-lu'u suna da sauri asara, don haka PDC ya rasa taurinsa da kaifi kuma ya zama mara amfani. Don hana irin wannan gazawar, dole ne a sanyaya masu yankan PDC daidai lokacin hakowa.

2. Carbide substrate

Carbide substrate an yi shi da tungsten carbide. Tungsten carbide (tsarin sinadarai: WC) wani sinadari ne da ke dauke da tungsten da carbon atom. Mafi mahimmancin nau'i na tungsten carbide shine foda mai kyau mai launin toka, amma ana iya danna shi kuma ya zama sifofi ta hanyar latsawa da sintering.

Tungsten carbide ana amfani da shi sosai a cikin haƙar ma'adinai a cikin manyan hammata na dutsen hamma, hammers na ƙasa, masu yankan abin nadi, ƙwanƙolin garma na doguwar bango, zaɓen shinge mai tsayi, haɓaka reamers, da injunan ban sha'awa na rami.

Zzbetter yana da tsauraran iko don albarkatun ƙasa na lu'u-lu'u grit da substrate carbide. Don yin aikin hako mai na PDC, muna amfani da lu'u-lu'u da aka shigo da su. Hakanan dole ne mu murkushe shi kuma mu sake siffata shi, muna sa girman barbashi ya zama iri ɗaya. Muna kuma buƙatar tsarkake kayan lu'u-lu'u. Muna amfani da Laser Barbashin Girman Girman Analyzer don nazarin girman rarrabuwar barbashi, tsabta, da girman kowane nau'in foda na lu'u-lu'u. Muna amfani da foda na budurwowi masu inganci tare da maki masu dacewa don samar da substrates carbide tungsten.

A Zzbetter, za mu iya bayar da fadi da kewayon takamaiman cutters.
