Itholakala kokubili kwe-straight blade kanye ne-helical blade,ama-centralizers aqinileziyithuluzi elibalulekile lokukhulisa amandla oketshezi ekusetshenzisweni komthombo ovundlile. Leziama-centralizersaklanywe ngezakhiwo zesimanjemanje, aqinisekisa ukuthi angakwazi ukumelana nomthelela omkhulu futhi aguge ngenkathi egcina ubuqotho ngisho nasemazingeni okushisa aphezulu.
Idizayini ye-blade eqondile yalezi zinto ezimaphakathi inikeza uketshezi oluhle kakhulu lokugeleza okubushelelezi, okusebenzayo ngaphakathi komthombo. Lo mklamo unciphisa ingozi yokudlula uketshezi, ukhuthaze ukugudluzwa kwemigodi esebenza kahle kanye nokuma kodaka okungcono. Ukwengeza, umklamo we-blade oqondile usiza ukuvimbela ukuhluka kwamashubhu okunamathela, kuthuthukise inqubo yokumba iyonke.
Ngakolunye uhlangothi, idizayini efanele ye-helical blade ithuthukisa ukuthuthumela koketshezi, idale umphumela we-vortex osiza ukuxubana kodaka nokugudluzwa koketshezi. Lo mklamo uwusizo ikakhulukazi lapho kudingeka khona uketshezi oluxutshwe kahle, njengasemithonjeni ephambukile noma lapho kubholwa ukwakheka okuhlukahlukene kakhulu. Idizayini ye-helical blade iqinisekisa isikhala esihle kakhulu se-casing, inciphisa ubungozi bokunamathela okuhlukile, futhi ithuthukisa ikhwalithi ye-wellbore.
Leziama-centralizers aqinilezifaneleka kokubili emithonjeni eqondile nevundlile, okuyenza ibe ithuluzi eliguquguqukayo ekusetshenzisweni okuhlukahlukene kokumba. Noma ngabe zisebenza ogwini noma zikhetha kahle i-offshore, lezi zindawo ezimaphakathi zinikeza ukusebenza okuhle nokuthembeka.
Lokhuama-centralizersisakhiwo sivumela ukufakwa kalula kunciphisa isikhathi somsebenzisi kanye nokukhulisa ukusebenza kahle. Ukwengeza, i-material inokumelana okuhle kakhulu kwamakhemikhali, okwenza lezi zinto ezimaphakathi zilungele uketshezi oluningi lokumba kanye nezimo ze-wellbore.
Kafushane, inhlanganisela yeama-centralizers aqinilengemiklamo ye-helical blade eqondile nesesandleni sokudla ikhulisa i-hydrodynamics futhi iqinisekisa ukugudluzwa okusebenzayo kwe-borehole kanye nokubekwa kodaka. Noma ngabe usebenza ogwini noma ogwini, leziama-centralizersangamathuluzi anokwethenjelwa athuthukisa ukusebenza kahle kokumba kanye nekhwalithi yobuhle jikelele.
