Lapho kuhlolwa ukusebenza kwephampu enodaka, ukwehluleka komshini okungalindelekile kuvame ukulandelelwa emuva ekuthwaleni isithunjana kunokuguguleka kokuphela-okumanzi. Ukusebenza ezindaweni ezichazwe ngamagrit abrasive, i-sludge esindayo, kanye{2}}nokugeza kwengcindezi ephezulu kubeka ingcindezi enkulu ekugcineni kwephampu.
Izindebe zokuvalwa kwezindebe ezijwayelekile kanye nokupakishwa kokuminyanisa okujwayelekile akuvamile ukuhlukanisa i-bearing cavity emijikelezweni yokusebenza enwetshiwe. Uma lezi zakhi zokuvala ziwohloka, izinto eziqinile kanye nomswakama zithuthela ngqo endlini, zihlanza i-lubricant futhi zibangele ukuthi ama-bearings abambe ngaphansi komthwalo. Ukuze kuqedwe lobu sengozini ethile, imiklamo yesimanjemanje esindayo{2}}isebenzisa{3}}okungaxhunywanwa naye,{4}}izigxivizo eziningi ze-labyrinth zesiteji ezibhangqwe namapuleti e-deflector. Lokhu kulungiselelwa kokuvala okunjiniyela kuvimbela ukungena kodaka, ukuphumula okungahleliwe okungahleliwe.
Ukuqinisekisa ubuqotho bezindlu ezithwalayo kuzinzisa izinhlelo zokunakekelwa kwezitshalo. Esikhundleni sokuphoqelela ukuvalwa kwesimo esiphuthumayo se-critical processing loop phakathi-noshintsho, amaqembu okulungisa angakwazi ukuhlehlisa ukuhlolwa kube izinguquko zonyaka ezihleliwe. Ngaphezu kwalokho, ukuvimbela ukukhiya okungazelelwe kuvikela yonke i-drivetrain emonakalweni oyinhlekelele wesibili, njengama-shaft agobile noma ama-motor agcwele kakhulu.
