Inkcazelo emfutshane:
I-Swivels ye-rotary drilling rig isetyenziswa ikakhulu ukuphakamisa i-kelly bar kunye nezixhobo zokomba. Amalungu aphezulu kunye asezantsi kunye ne-intermediates ye-elevator zonke zenziwe ngensimbi ephezulu ye-alloy; Zonke iibheringi zangaphakathi zamkela umgangatho we-SKF, olungiselelwe ngokukodwa, kunye nokusebenza okugqwesileyo; Zonke izinto zokutywinwa ngamalungu athunyelwa kwamanye amazwe, axhathisa ukubola kunye nokuguga.

Iingenelo
1. I-swivel ye-rotary drilling rig yisakhiwo sokudibanisa isinyithi, kunye namalungu aphezulu nangaphantsi, ama-intermediates, njl. Emva komatshini ongqongqo, inkqubo yonyango yobushushu engqongqo iya kwenziwa phambi kokulungiswa.
2. Ukuthwala i-SKF kunye ne-FAG zamkelwa ukuthwala kwangaphakathi.
3. Into yokutywina i-NOK, igrisi kwi-cavity yangaphakathi ethwele akulula ukuvuza, kwaye udaka kunye ne-sundries kwi-cavity yangaphandle akulula ukungena kwi-bearing cavity, ukwenzela ukuba kuqinisekiswe ukusebenza okuqhelekileyo kokuthwala.
