IADC637 9 7/8 tricone bits yokubhoboza imithombo yamanzi esitokweni sokwakheka kwamadwala aqinile

I-IADC 637 (Code X) TCI journal sealed bearing tricone bit, ifakwe isivikelo segeji, yenzelwe ngokukhethekile ukwakheka okuqinile okunamandla aphezulu okucindezela asukela ku-100-150 MPa (14,500-23,000 PSI) — inzuzo eyinhloko ebonakala empendulweni yeklayenti lokugcina. Ngobubanzi bosayizi obungu-9 5/8” kuya ku-9 7/8”, isebenzisa izinto ze-tungsten ukuze ivumelane nezidingo zokujikeleza kodaka ekubholeni imithombo yamanzi, futhi ihambisana namajethi avamile anezinhlangothi ezintathu. Amakhasimende abika ukumelana kwayo okuhle kakhulu nokuguguleka kanye nokujikeleza kodaka okuzinzile, okuvumela ukusebenza kahle kokwakheka okuqinile. Okwamanje, umklamo wokuvikela we-bearing kanye negeji ovaliwe wandisa impilo yawo yesevisi, uthuthukisa ukusebenza kahle kokubhoboza kanye nokonga izindleko.ukusebenza.
