I-eccentric reduction rubber soft joint ithambile kakhulu futhi ilula.Amajoyinti enjoloba anciphisa i-Eccentric angasetshenziselwa ukuxhuma amapayipi kanye nokuvikela ama-valve ephampu.Uma okokusebenza kusendaweni ekhethekile yokusebenza, kungadlala indima engcono.
Amajoyinti enjoloba e-eccentric anobubanzi obuhlukene anezakhiwo zokumelana nengcindezi ephezulu, ukunwebeka okuhle, ukugudluka okukhulu, ukuchezuka kwamapayipi alinganiselayo, ukumuncwa ukushaqeka kanye nokunciphisa umsindo.Isetshenziswa kakhulu ekukhipheni amanzi, emanzini ajikelezayo, e-HVAC, ekwenziweni kwamaphepha, kwezemithi, ekufakeni amapayipi abalandeli, njll. Amalunga enjoloba anciphisa i-Eccentric awakwazi ukugqwala.Endaweni edla kakhulu, amalunga enjoloba anobubanzi obuhlukene kufanele asetshenziswe njengezinqamuleli zokushaqeka.
Umehluko kanye nokusetshenziswa kwamajoyinti enjoloba agxilile kanye ne-eccentric:
Ukunciphisa ukujoyina kwerabha kusetshenziselwa ukuxhuma amapayipi ngobubanzi obuhlukene.Ngokujwayelekile ihlukaniswe yaba ijoyinti yerabha egxilile kanye nejoyinti lerabha eliyi-eccentric.Ijoyinti lerabha elinciphisa i-Eccentric, isikhungo sayo sendilinga singekho emugqeni ofanayo.Kusebenza ekumisweni kwamapayipi eduze kodonga noma phansi, ukuze kongiwe isikhala, futhi kuxhunywe amapayipi amabili ngobubanzi obuhlukene ukuze kushintshwe izinga lokugeleza.Ngejoyinti lerabha isikhungo sendilinga esisemgqeni ofanayo, kubizwa ngokuthi amajoyinti enjoloba anciphisa ukugxila.Ijoyinti yenjoloba encishisiwe egxile kakhulu esetshenziselwa ukuncishiswa kwegesi noma uketshezi oluqondile.Imbobo yepayipi lejoyinti lerabha elinciphisa i-Eccentric libhalwe isiyingi, ngokuvamile lisebenza epayipini loketshezi elivundlile, lapho iphoyinti lepayipi lixhumene libheke phezulu, eliyisicaba ekufakweni okuphezulu, ngokuvamile elisetshenziswa ekungeneni kwepompo, kunenzuzo ekuqedeni amandla;lapho indawo oxhumene nayo ishona phansi, leyo iyisicaba ekufakweni okungaphansi, evame ukusetshenziswa ekulawuleni ukufakwa kwamavalvu, kunenzuzo ekuphumeni kwayo.Ijoyinti yenjoloba encishisiwe egxilile ivuna ukugeleza koketshezi, ukuphazamiseka kwesimo sokugeleza kokukhanya lapho kwehliswa, yingakho igesi kanye nepayipi loketshezi elime mpo lisebenzisa ijoyinti lerabha elinciphisa ukugxilisa.Njengoba uhlangothi olulodwa lwejoyinti yenjoloba yokunciphisa i-eccentric liyisicaba, lilungele ukukhathala kwegesi noma uketshezi, kanye nokunakekelwa, yingakho ipayipi loketshezi elifaka elivundlile lisebenzisa ijoyinti lenjoloba elehlisa i-eccentric.
