Isitywina se-oyile edadayo ligama eliqhelekileyo lamatywina adadayo, elodidi lomatshini wokutywina kumatywina aguqukayo.Inomsebenzi obalaseleyo wokutywina kwiindawo zokusebenza ezirhabaxa ezinje ngomgubo wamalahle, intlenga, kunye nomphunga wamanzi.Itywina lomatshini wokutywina lisetyenziswa ikakhulu kwisantya esiphantsi kunye neemeko zomthwalo onzima.Ineenzuzo zokumelana nokunxiba, imbuyekezo ngokuzenzekelayo emva kokuphela kokugqoka ubuso, ukusebenza okuthembekileyo, kunye nesakhiwo esilula, kwaye isetyenziswa ngokubanzi kumatshini wokumba amalahle.Njengomatshini wokuhamba nge-bulldozer, i-scraper conveyor head (umsila) amacandelo e-sprocket, indlela yokulayisha i-roadheader kunye necandelo le-cantilever, i-drum yokusika ekhohlo nasekunene kunye nabanciphisi bemishini yokumba amalahle eqhubekayo, njl.
Ukudadaitywina yeoliisetyenziswa kwisinciphisi seplanethi yenxalenye yokuhamba koomatshini bokwakha ukutywina ngokuguquguqukayo ubuso besiphelo secandelo.Ngenxa yokuthembeka kwayo okuphezulu, ikwasetyenziswa njengetywina eliguquguqukayo kwishaft ephumayo yevili lebhakethi le-dredger.Olu hlobo lwetywina lolotywino lomatshini kwaye lubandakanya umsesane odadayo owenziwe ngemathiriyeli ye-ferroalloy kunye ne-nitrile yerabha ehambelana ne-O-ring seal.Amakhonkco adadayo asetyenziswa ngababini, enye ijikeleza kunye necandelo elijikelezayo kwaye enye imile ngokwentelekiso, eyahluke kakhulu kwiringi yetywina yeoli.
Isitywina seoli esidadayo senziwe ngamakhonkco entsimbi amabini afanayo kunye namakhonkco amabini erabha.Umgaqo wayo wokusebenza kukuba izibini zeerubha zamakhonkco zenza indawo evaliweyo kunye ne-cavity (kodwa ingadibanisi ne-shaft) phantsi kwenkxaso yeentsimbi zetsimbi.Xa ujikeleza, iindawo ezimbini zomhlaba zamakhonkco esinyithi zihambelana ngokusondeleyo kwaye zityibilika komnye nomnye, ziqinisekisa ukusebenza kakuhle kwelinye icala, kunye nokutywinwa ngokufanelekileyo kuthuli lwangaphandle, amanzi, i-sludge, njl., ukukhusela igrisi yangaphakathi yokuthambisa ekuvuzeni.
Umgaqo wokutywina wetywina le-oyile edadayo kukuba ukuguqulwa kwamakhonkco amabini adadayo okubangelwa yi-axial compression ye-O-ring kuvelisa amandla oxinzelelo kwisiphelo sokutywinwa kobuso bomsesane odadayo.Ngokunxitywa okufanayo kobuso besiphelo sokutywinwa, amandla alastiki agcinwe yiIrabha O-ringikhutshwa ngokuthe ngcembe, ngaloo ndlela idlala indima yembuyekezo ye-axial.Umphezulu wokutywina unokugcina ukubambelela kakuhle kwixesha elimiselweyo, kwaye ubomi bokutywinwa ngokubanzi bungaphezulu kwe-4000h.
Ukudadaitywina yeoliluhlobo olukhethekileyo lwetywina lomatshini eliphuhliswe ukuziqhelanisa neendawo zokusebenza ezirhabaxa.Ineenzuzo zokuxhathisa okuqinileyo kongcoliseko, ukuxhathisa ukunxiba, ukuchasana nempembelelo, ukusebenza okuthembekileyo, imbuyekezo ezenzekelayo yokunxiba kobuso, kunye nesakhiwo esilula.Isetyenziswa kakhulu kwiimveliso zoomatshini bobunjineli, kwaye ikwasetyenziswa ngokubanzi kwiindlela ezahlukeneyo zokuhambisa, izixhobo zonyango lwesanti, kunye nezixhobo zekhonkrithi.Kumatshini wemigodi yamalahle, isetyenziswa ikakhulu kwi-sprocket kunye nesinciphisi sabahambisi be-scraper, kunye nendlela yokuhambisa, ingalo ye-rocker, idrum, kunye nezinye iindawo zoomatshini bemigodi yamalahle.Olu hlobo lwemveliso yokutywinwa lubanzi kwaye lukhulile ekusebenziseni oomatshini bobunjineli kunye nezixhobo, kodwa kwamanye amashishini, ngenxa yokusetyenziswa okulinganiselweyo, ukungabikho kwedatha yethiyori esisiseko kunye namava okusebenzisa, ukusilela ngexesha lokusetyenziswa kuqhelekile, okwenza kube nzima. ukuphumeza umphumo olindelekileyo.
Gcina i-gap ethile phakathi kwendandatho ejikelezayo kunye ne-shaft ejikelezayo, ekwazi ukudada ngokukhululekileyo, kodwa ayikwazi ukujikeleza kunye ne-shaft ejikelezayo.Inokwenza kuphela i-radial sliding edadayo kwaye igcine i-eccentricity ethile kunye neziko le-shaft phantsi kwesenzo somxhuzulane.Xa i-shaft ijikeleza, i-fluid yokutywina (ngokuqhelekileyo ioli) ifakwa ngaphandle ukuze yenze ifilimu yeoli kwisithuba esiphakathi kwe-shaft kunye neringi edadayo.Ngenxa yesenzo se-oil wedge force eyenziwe ngexesha lokujikeleza kwe-shaft, umlinganiselo othile woxinzelelo lwefilimu yeoli ugcinwa ngaphakathi kwefilimu yeoli, evumela ukuba i-ring floating igcine "ukulungelelaniswa" ngokuzenzekelayo kunye neziko le-shaft, ukunciphisa kakhulu i-gap kwaye ngokufanelekileyo. ukufezekisa ukutywinwa kokuvuza okuphakathi kwamanzi.Iinzuzo zayo kukuzinza kokutywinwa kokusebenza, ukuthembeka, kunye nobomi benkonzo ende;Uluhlu lweparameter esebenzayo yesitywina lubanzi (kunye noxinzelelo olusebenzayo ukuya kuthi ga kwi-MPa engama-30 kunye nobushushu obusebenzayo be--100 ~ 200 ℃);Ngokukodwa ngokufanelekileyo ukutywinwa kwemithombo yegesi kwiicompressor ze-centrifugal, ayinako ukuphumeza ukuvuza kokusingqongileyo okusemoyeni, kwaye ilungele ukutywinwa kwemithombo yeendaba ezinokutsha, eziqhumayo, ezinetyhefu kunye nexabiso lerhasi.Ukungalungi kukuba iimfuno zokulungisa amakhonkco adadayo ziphezulu, zifuna inkqubo yeoli yokutywina ekhethekileyo;Kukho ukuvuza okuninzi kwangaphakathi, kodwa kusekwimo yokujikeleza kwangaphakathi, okwahlukileyo ngokomgangatho ekuvuzeni kwezitywina zoomatshini.Isetyenziswa ngokubanzi kwizitywina eziguquguqukayo kwiicompressor ze-centrifugal.
