Ekufakweni kukasimende kwemithombo kawoyela negesi, ama-centralizer angamathuluzi abalulekile. Kuyidivayisi ekhethekile esetshenziswa kakhulu ukusiza isikhungo se-casing emgodini womthombo ngesikhathi senqubo yokufaka usimende. Olunye uhlobo lwe-centralizer eselidume kakhulu emboninii-centralizer ene-hinged bow-spring.
Ii-centralizer ene-hinged bow-springyakhelwe ngoxhumano olunamahingithi, okwenza kube lula ukufaka nokuqinisekisa ukulingana okuvikelekile eduze kwekesi. Lolu hlobo lwe-centralizer lunikeza nenzuzo yezindleko zokuthutha ezincishisiwe, njengoba zingagoqwa kalula futhi zipakishwe ukuze zithunyelwe kahle futhi zigcinwe.
Ngesikhathi sokusebenza kukasimende, umgomo oyinhloko wokusebenzisa ama-centralizers ukuqinisekisa ukuthi i-casing igxile kahle emgodini womthombo. Lokhu kubalulekile ukuze kube nomsebenzi ophumelelayo usimende, njengoba kuvumela ukusatshalaliswa okufanayo kukasimende ebhodleleni, okugcina kwakha umthombo oqinile nothembekile. Ii-centralizer ene-hinged bow-springidlala indima ebalulekile ekufezeni lokhu, njengoba idizayini yayo isiza ekwenzeni ngcono ukuhamba kukasimende ebhodleleni, kuncishiswe ubungozi bokumbozwa kahle kukasimende kanye nezindawo ezingaba buthaka emgodini womthombo.
Ukuqinisekisa izinga nokusebenza kweama-centralizers ane-hinged bow-spring, ukulayisha nokusetha kabusha ukuhlolwa kwamandla kwenziwa ukuze kutholwe idatha yokuhlola enembile. Le nqubo yokuhlola ivumela ukuqinisekiswa kwekhono le-centralizer lokugcina isimo sayo nobuqotho ngaphansi kwamazinga ahlukahlukene okucindezela namandla, iqinisekisa ukuthi ingenza ngempumelelo umsebenzi wayo ohlosiwe emsebenzini wokuhlanganisa umhlaba wangempela.
Ekuphetheni,ama-centralizers ane-hinged bow-springziyithuluzi elibalulekile ekusebenzeni kukasimende kwemithombo kawoyela negesi. Idizayini yabo emisha, ukufakwa okulula, nezici zokuthutha ezonga izindleko zibenza babe ukukhetha okuthandwayo ezinkampanini eziningi zikawoyela negesi. Ngemizamo eqhubekayo yokuthuthukisa inqubo yokuklama neyokukhiqiza, imboni ingalindela ama-centralizers athembeke nakakhulu futhi asebenza kahle kakhulu esikhathini esizayo, enikeza ukwesekwa okubalulekile kokusebenza kukasimende emithonjeni kawoyela negesi.
