Uchungechunge lwe-AC lweyunithi yokwelapha yomthombo womoya womoya we-FRL (isihlungi, Isilawuli Sokucindezela, i-lubricator) iyithuluzi elibalulekile lesistimu yomoya. Lo mshini uqinisekisa ukusebenza okuvamile kwemishini yomoya ngokuhlunga, ukulawula ukucindezela, nokugcoba umoya.
Idivayisi yenhlanganisela ye-AC yochungechunge lwe-FRL ikhiqizwa kusetshenziswa ubuchwepheshe obuthuthukisiwe nezinto zokwakha, ngokusebenza okuthembekile nokusebenza okuzinzile. Ngokuvamile zenziwe nge-aluminium alloy noma ipulasitiki futhi zinezici zokumelana nokungasindi nokugqwala. Idivayisi isebenzisa izakhi zokuhlunga ezisebenza kahle kanye nama-valve alawula ingcindezi ngaphakathi, angahlunga kahle umoya futhi alungise ukucindezela. I-lubricator isebenzisa i-lubricant injector eguquguqukayo, engalungisa inani lokuthambisa ngokwesidingo.
Idivayisi yenhlanganisela ye-AC yochungechunge lwe-FRL isetshenziswa kabanzi ezinhlelweni ezihlukahlukene zomoya, njengemigqa yokukhiqiza yasefekthri, imishini yemishini, imishini yokuzenzakalela, njll. Abahlinzeki nje kuphela ngomthombo womoya ohlanzekile futhi ozinzile, kodwa futhi banweba impilo yesevisi yemishini yomoya futhi bathuthukise. ukusebenza kahle.
