Imyitozo ya PDC bits nozzles
Intangiriro
Carbide nozzle ya sima ni kimwe mubice byingenzi bigize diyama ya diyama, tungsten carbide drill bit nozzle ikoreshwa muguhindura, gukonjesha, no gusiga amavuta yibice byimyitozo, nozzles ya karbide nayo irashobora guhanagura ibyuma byamabuye hepfo yiziba hamwe no gucukura amazi mu bihe byakazi byumuvuduko mwinshi, kunyeganyega, umucanga, no guhubuka bigira ingaruka mugihe cyo gushakisha peteroli na gaze gasanzwe.Carbide nozzles nayo ifite hydraulic rock gucamo ibice.Nozzle isanzwe ni silindrike;irashobora gutanga umusaruro uringaniye ukwirakwiza hejuru yigitare.
Tungsten karbide nozzles ikoreshwa cyane cyane mugukata neza hamwe na bits ya cone roller yo gukonjesha amazi no gukaraba ibyondo, dukurikije gucukura ibidukikije bya geografiya, tuzahitamo imigezi itandukanye y'amazi n'ubunini bw'imyobo muburyo bwa tungsten.
Ubwoko bwa karbide nozzles
Hariho ubwoko bubiri bwingenzi bwa karbide nozzles ya bits.Imwe iri hamwe nuudodo, indi ntayindi.Carbide nozzles idafite urudodo ikoreshwa cyane cyane kuri biti ya roller, karbide nozzles ifite urudodo ikoreshwa cyane kuri biti ya PDC.Ukurikije ibikoresho bitandukanye byo gukoresha ibikoresho, hari ubwoko 6 bwurudodo rudodo rwa bits ya PDC:
1. Kwambukiranya imirongo ya shobora
2. Amashurwe yindabyo zo mumutwe
3. Inyuma ya mpande esheshatu
4. Imbere ya mpandeshatu y'imbere
5. Y ubwoko (3 slot / grooves) urudodo
6. ibyuma byiziga byimyitozo bito no gukanda.
Igikoresho cya Kedel kirashobora kubyara ubwoko bwinshi bwimitwe ya nozzle ya PDC ya drits bits muri metric na imperuka.Ihuriro ryigihugu rihuriweho hamwe, urudodo rwiza, hamwe nudodo twihariye harimo icyiciro cya 3 cyuzuye, ukuri kwukuri kurwego rwabanyamerika.Ukurikije ibyo usabwa kuri biti ya karbide, birashobora gushushanywa no guhinduranya.
Ntidushobora kubyara gusa tungsten karbide nozzles, ariko kandi turashobora no kubyara amajwi akurikije ibishushanyo cyangwa ingero.Nozzles iraboneka muburyo butandukanye bwuburyo bwubunini hamwe nubunini bukomatanyirijwe kumurongo wo hasi-umwobo.Ibyiciro byacu-byageragejwe byateguwe kuburemere bukomeye no kwambara birwanya imbaraga-nyinshi za porogaramu.Turashobora guhuza icyiciro cyihariye cya tungsten karbide yibikoresho byawe.Dufite uburambe bwo gukora imiterere nubunini butandukanye bwa tungsten alloy nozzles.
