PDC waxay xirxirtaa tuubooyinka
Hordhac Wax-soo-saar
Neefka carbide-ka sibidhka ah waa mid ka mid ah qaybaha muhiimka ah ee birta dheemanka ah, tungsten carbide tungsten kabid sanka sanka lagu shubo si aad u nadiifiso, u qaboojiso, iyo saliidda talooyinka tuubooyinka feerka dareere ku jira xaaladaha shaqada ee cadaadiska sare, gariir, ciid, iyo slurry saameeya inta lagu jiro raadinta saliidda iyo gaaska dabiiciga ah.Nozzles-ka Carbide sidoo kale waxay leeyihiin saameyn kala-jajabineed.Dhuunta caadiga ah waa cylindrical;waxay soo saari kartaa qaybinta cadaadiska dheellitiran ee dusha dhagaxa.
Neefsashada carbide tungsten waxaa inta badan loo isticmaalaa biraha goynaya go'an iyo kootada kolayba biraha qaboojinta iyo dhaqidda dhoobada, sida ku cad qodista deegaanka juqraafi, waxaan dooran doonaa socodka biyaha kala duwan iyo cabbirka dalool qaabka qaab tungsten nozzles.
Noocyada sanbabada carbide
Waxaa jira laba nooc oo waaweyn oo kaarbiid nozzles oo loogu talagalay jajabyada layliga.Mid baa dun leh, midna dun malaha.Nozzles kaarbide ah oo aan dun lahayn ayaa inta badan loo isticmaalaa birta rullaluistemadka ah, nalalka carbide ee dunta leh ayaa inta badan lagu dabaqaa qaybta laydhka ee PDC.Marka loo eego furaha qalabka wax ka qabashada ee kala duwan, waxaa jira 6 nooc oo nozzles dun ah oo loogu talagalay jajabyada PDC:
1. Duubka dunta jeexdin ee ka gudubta
2. Duubka dunta nooca ubaxa plum
3. Duubka dunta lix geesoodka ah ee dibadda ah
4. Duubabka dunta lix geesoodka ah ee gudaha
5. Nooca Y (3 Afyare / grooves) dunta dunta
6. Biraha biibiile ee giraangiraha giraangiraha iyo tuubooyinka dillaaca ee riixaya.
Qalabka Kedel wuxuu soo saari karaa inta badan noocyada dunta biibiile ee PDC ee dunta metric iyo Imperial.dunta qalafsan ee qaran midaysan, dun fiican, iyo dun gaar ah oo ay ku jiraan fasalka saxda ah ee 3, saxnaanta ugu saraysa heerka Maraykanka.Marka loo eego shuruudahaaga loo yaqaan 'carbide bit', waxaa lagu qaabayn karaa iyada oo la beddeli karo.
Ma soo saari karno oo kaliya tungsten carbide nozzles caadiga ah, laakiin sidoo kale waxaan awoodnaa inaan soo saarno nozzles habaysan iyadoo loo eegayo sawirada ama muunadaha.Nozzles ayaa lagu heli karaa qaabab kala duwan oo kala duwan iyo isku darka cabbirka inta badan codsiyada qodista godka hoose.Darajooyinkayada goobta lagu tijaabiyay waxaa loogu talagalay adkaanta ugu badan iyo xirashada caabbinta ee codsiyada awoodda qulqulka sare.Waxaan kuu diyaarin karnaa qalabka carbide tungsten ee gaarka ah adiga.Waxaan leenahay khibrad si aan u soo saarno qaabab kala duwan iyo cabbirro tungsten alloy nozzles.
