Tungsten carbide Nozzle don PDC Drill Bit

    PDC drill bits kayan aikin fasa dutse ne masu inganci da ake amfani da su sosai wajen hako mai da iskar gas, binciken yanayin kasa, da sauran fagage. Tungsten carbide bututun ƙarfe yana ɗaya daga cikin abubuwan da ke cikin sa. Yawanci ana shigar da shi a ramin ruwa na ɗimbin rawar jiki na PDC, tana allurar ruwa mai matsa lamba don samar da sanyaya, tsaftacewa,  da kuma taimakawa wajen fasa dutse. Ayyukansa yana tasiri kai tsaye ga rawar jiki amma yana da

rayuwar sabis da ingancin hakowa.

I.  Hanyar Haɗin Nozzle:

    Dole ne ya dace da ramin ruwa na PDC drill bit. Haɗin gama gari shine haɗin da aka zare (na waje ko na ciki, tare da daidaiton matakin 3A zuwa

    tabbatar da cewa babu yabo a karkashin babban matsin lamba). Wasu ƙananan nozzles suna amfani da tsangwama (latsa-fit), wanda ke hana sassautawa bayan shigarwa.

II. Halayen Abun Ciki: Tungsten Carbide (WC)

    1. Babban Tauri da Sawa Resistance: Tungsten carbide's taurin shine na biyu kawai ga lu'u-lu'u, yana mai da shi juriya ga yashwar da barbashi a cikin ruwa mai hakowa (kamar yashi da tarkacen ƙarfe), yana tsawaita rayuwar bututun ƙarfe.

    2. Resistance Lalacewa: Yana jure lalata daga abubuwan da ke tattare da sinadarai a cikin ruwan hakowa (kamar gishiri da acid).

    3. Tasiri Resistance: Tungsten carbide yawanci yana amfani da cobalt (Co) azaman a

daure, samar da wani mataki na tauri da hana karaya.

III. Fasalolin Tsarin Tsarin Carbide Nozzle

    1. Streamlined Inner Bore: Yana rage tashin hankali kuma yana inganta ingantaccen ruwa. Nau'o'in gama-gari sun haɗa da:

    2. Madaidaicin Bore: Mai sauƙi kuma mai dorewa, dace da hakowa na al'ada.

    3. Venturi: Tsarin haɗakarwa-mai haɗawa yana haɓaka ƙimar kwarara kuma yana haɓaka cire guntu.

    4. Daban-daban Girma: The bututun ƙarfe diamita na ciki (yawanci 6-16mm) aka zaba bisa ga hakowa ruwa kwarara kudi da ake bukata allura gudu.

    Zane mai Matsala: Babu buƙatar maye gurbin duk abin rawar soja bayan lalacewa, rage farashin kulawa.

IV. Babban ayyuka na tungsten carbide nozzles sune kamar haka:

    1. sanyaya masu yankan

Masu yankan ɗigon rawar soja na PDC suna haifar da babban adadin zafi yayin da suke jujjuyawa cikin sauri don yanke dutsen.  Yawan zafin jiki na iya haifar da carbonization da gazawar Layer lu'u-lu'u. Ruwan hakowa mai tsananin ƙarfi da ake fitarwa daga bututun tungsten carbide bututun ƙarfe yana kawar da wannan zafin kai tsaye, yana kiyaye zafin mai yankewa a cikin amintaccen kewayon   (yawanci ƙasa  700°C)  kuma yana hana lalacewar zafi.

    2. Tsaftace Yankan Dutse

Yankan dutsen da aka yi a lokacin yankan na iya tarawa a kusa da masu yankan, yana haifar da "ballin laka" (haɗin yankan yankan da hakowa ruwa da ke manne da bututun haƙori), yana rage ƙarfin fashewar dutsen. Jet ɗin ruwa mai sauri daga bututun ƙarfe ya watse da sauri tare da kawar da yankan, yana riƙe ingantaccen hulɗa tsakanin mai yankewa da dutsen.

    3. Rushewar Dutsen Taimakon Ruwa

Jet ɗin daga bututun ƙarfe (a cikin sauri har zuwa 100-200 m / s) yana tasiri saman dutsen, yana haifar da fashewar hydraulic. Wannan synergistic sakamako, haɗe tare da inji yankan mataki na cutters, rage dutse karya juriya, muhimmanci ƙara shigar azzakari cikin farji gudun, musamman a cikin wuya formations.

V. Aikace-aikace

Ana amfani da nozzles na Carbide da farko a cikin al'amuran masu zuwa:

    1. Tsarin sassauƙa mai laushi zuwa matsakaita mai ƙarfi, irin su shale da dutsen farar ƙasa, inda suke dacewa da ingantaccen aikin juzu'i na raƙuman ruwa na PDC.

    2.  Rijiyoyi masu zurfi/tsaye suna buƙatar matsa lamba mai yawa da madaidaicin iko na ruwa, inda amincin nozzles carbide na tungsten yana da mahimmanci.

    3.  Samfuran da ba su da kyau sosai, kamar dutsen yashi na quartz, suna ba da juriya mafi inganci idan aka kwatanta da daidaitattun nozzles na ƙarfe na gami.
