Okukola ku silinda .

Nga ekitundu ekikulu ekya ssilindala z’amazzi, okusima empagi emu, ebiwanirizi by’amazzi, ebipipa by’emmundu n’ebintu ebirala, omutindo gw’okugulongoosa gukosa butereevu obulamu n’obwesigwa bw’ekintu kyonna. Ebyetaago by’okukola ku ssiringi biri waggulu, era ekyetaagisa kyayo eky’omunda eky’obukaluba ku ngulu ye RA0.4~0.8&UM, era obuziyiza bwa coaxiality n’okwambala byetaagibwa nnyo. Ekikulu mu ssiringi eno kwe kulongoosa ebinnya ebiwanvu, era okulongoosa kwayo bulijjo kubadde kutawaanya abakozi abakola.
Enkola y’okuyiringisibwa (rolling process) ekolebwa. Okuva layeri y’okungulu bw’erina okunyigirizibwa okusigaddewo ku ngulu, kiyamba okuggalawo enjatika entonotono ez’okungulu n’okulemesa okugaziwa kw’okukulugguka. bwe kityo ne kitereeza okuziyiza okukulukuta kw’amazzi ku ngulu, n’okulwawo okuzaala oba okugaziwa kw’enjatika z’obukoowu, bwe kityo ne kitereeza amaanyi ga ssiringi. Okuyita mu kukola okuyiringisibwa, oluwuzi olukaluba okukola olw’ennyogovu lukolebwa ku ngulu w’okuyiringisibwa, ekikendeeza ku kukyukakyuka kwa laasitiki ne pulasitiika okw’oludda lw’okukwatagana olw’ekibiri ekisenya, bwe kityo ne kitereeza obuziyiza bw’okwambala obw’ekisenge eky’omunda ekya ssilindala, n’okwewala okwokya okuva ku kusenya. Oluvannyuma lw’okuyiringisibwa, okukendeeza ku muwendo gw’obukaluba bw’okungulu kuyinza okulongoosa eby’obugagga ebikwatagana.
Siliinda y’amafuta kye kitundu ekisinga obukulu mu byuma bya yinginiya. Enkola y’okulongoosa ey’ennono eri nti: okukuba omubiri gwa ssiringi-obutuufu okuboola omubiri gwa ssiringi-okusitula omubiri gwa ssiringi. Enkola y’okuyiringisibwa ye: Omubiri gwa ssiringi ogw’okusala - Omubiri gwa ssiringi oguboola obulungi - Omubiri gwa ssiringi eziyiringisibwa. Enkola eno erimu ebitundu 3, naye okugerageranya obudde kuli nti: okusiiga mita emu ey’omubiri gwa ssiringi kitwala ennaku nga 1-2, ate okuyiringisibwa mita emu ey’omubiri gwa ssiringi kitwala eddakiika nga 10-30. Okugerageranya okuteeka ssente mu bizinensi: ekyuma ekikuba oba ekyuma ekikuba ebyuma (enkumi n’enkumi okutuuka ku bukadde), okusalako (1,000 okutuuka ku makumi). Oluvannyuma lw’okuyiringisibwa, obukaluba bw’ekinnya kungulu bukendeezebwa okuva ku RA3.2~6.3UM nga tebunnayiringisibwa okutuuka ku RA0.4~0.8&UM, obukaluba bw’okungulu obw’ekinnya bwongerwako ebitundu nga 30%, era amaanyi g’obukoowu ag’okungulu kwa ssilindala gongerwako ebitundu 25%. Singa enkola ya ssiringi yokka erowoozebwako, obulamu bw’obuweereza bwa ssiringi bwongerwako emirundi 2~3, era enkola y’okuboola n’okuyiringisibwa ekola bulungi emirundi nga 3 okusinga enkola y’okusiiga. Ebiwandiiko ebyo waggulu biraga nti enkola y’okuyiringisibwa ekola bulungi era esobola okulongoosa ennyo omutindo gw’okungulu kwa ssilindala.
Oluvannyuma lw’okuyiringisibwa, tewali sharp tiny edge ku ngulu wa cylinder, era long-Term movement friction tejja kwonoona seal ring oba seal, ekintu ekikulu ennyo mu makolero g’amazzi.
