Umpakishi we-RTTS ubukhulu becala yenziwe nge-J-shaped groove transposition mechanism, i-mechanical slips, i-rubber barrel kunye ne-anchor ye-hydraulic. Xa ipakethe ye-RTTS ithotywa emthonjeni, i-friction pad ihlala isondelelene nodonga lwangaphakathi lwe-casing, i-lug isekupheleni kwe-groove ye-transposition, kwaye i-rubber barrel ikwi-free state. Xa umpakishi wehliswa kubunzulu obumiselwe kwangaphambili, phakamisa kuqala umtya wombhobho ukuze i-lug ifikelele kwindawo ephezulu ye-slot emfutshane, kwaye ngelixa ugcina i-torque, yehlisa umtya wombhobho ukuze usebenzise umthwalo woxinzelelo.
Ngenxa yokuba ujikelezo lwesandla sasekunene soluhlu lombhobho lubangela ukuba ilug ihambe isuka kumqolo omfutshane iye kwigophe elide, i-mandrel esezantsi ihlehla xa icinezelwe, icone yokutyibilika ihlehla ukuze ivule isiliphu, kwaye imiphetho yebloko yealloyi ivuliwe. i-slip ifakwe kwi-casing wall, kwaye emva koko Iikhatriji zerabha zanda phantsi koxinzelelo de zombini iikhatriji zicinezelwe ngokubhekiselele eludongeni lwe-casing, zenze isitywina.
Xa umahluko woxinzelelo olubi lovavanyo mkhulu kwaye uxinzelelo olungaphantsi kombhobho werabha wokupakisha mkhulu kunoxinzelelo lwekholamu ye-hydrostatic ngaphezulu kompakishi, uxinzelelo olusezantsi luya kuhanjiswa kwi-anchor ye-hydraulic ngombhobho wevolumu, kubangele ukutyibilika kwe-anchor ye-hydraulic ukuvula kwaye ukutyibilika ukunyuka. I-alloy slips ijonge phezulu, ukwenzela ukuba umpakishi ahlaliswe ngokuqinileyo eludongeni lwangaphakathi lwe-casing ukukhusela umtya wombhobho ukusuka phezulu.
Ukuba umpakisheli uphakanyiselwe ngaphandle, sebenzisa nje umthwalo onzima, vula ivalve yokujikeleza kuqala ukulinganisa uxinzelelo oluphezulu kunye nolusezantsi lwe-cylinder yerabha, i-hydraulic anchor slips iya kurhoxa ngokuzenzekelayo, kwaye emva koko iqhubeke nokuphakamisa, i-cylinder yerabha iya kukhulula uxinzelelo. nokubuyela kwinkululeko yayo yantlandlolo. Ngeli xesha, i-lug ibuyela ngokuzenzekelayo kwi-groove emfutshane ukusuka kwi-groove ende kunye ne-slope, i-cone ihambela phezulu, kwaye i-slips ihoxisiwe, kwaye umpakishi unokuphakanyiswa ngaphandle kwe-wellbore.
