Noma ngubani olungisayo futhi oke walungisa iphampu noma u-gearbox uyazi ukuthi enye yezinto ezihlale idinga ukushintshwa ngesikhathi kulungiswa i-lip seal.Ivamise ukulinyazwa uma ikhishwa noma ihlakazwa.Mhlawumbe yi-lip seal eyenza ukuthi idivayisi ikhishwe ngenxa yokuvuza.Nokho, iqiniso lihlala liwukuthi izindebe zomlomo ziyizingxenye ezibalulekile zomshini.Bacupha uwoyela noma ugcobe futhi basize ekunqandeni ukungcola.Ama-lip seal angatholakala cishe kunoma iyiphi into yasefekthri, ngakho-ke kungani ungaziniki isikhathi sokufunda ukukhetha nokuzifaka ngendlela efanele?
Inhloso eyinhloko ye-lip seal ukugcina ukungcola ngaphandle ngenkathi kugcinwa ukugcotshwa.Eqinisweni, ama-lip seal asebenza ngokugcina ukungqubuzana.Angasetshenziswa ezinhlelweni ezihlukahlukene, kusukela kumishini ehamba kancane ukuya ekuzungeziseni ngesivinini esikhulu, kanye namazinga okushisa asukela ku-sub-zero ukuya ngaphezu kuka-500 degrees Fahrenheit.
Ukuze isebenze, uphawu lomlomo kufanele lugcine ukuxhumana okufanele nengxenye yalo ejikelezayo.Lokhu kuzothonywa ukukhethwa okufanele kwezigxivizo, ukufakwa nokugcinwa kokugcinwa kokufakwa kwezigxivizo.Ngivame ukubona izindebe zomlomo ezintsha ziqala ukuvuza ngokushesha nje lapho zifakwa emsebenzini.Lokhu kuvame ukwenzeka ngenxa yokufakwa okungafanele.Amanye ama-seal azovuza ekuqaleni, kodwa azoyeka ukuvuza uma into yokuvala isihleli ku-shaft.
Ukugcina i-lip seal esebenzayo kuqala ngenqubo yokukhetha.Lapho ukhetha izinto zokwakha, kufanele kucatshangelwe izinga lokushisa lokusebenza, i-lubricant esetshenzisiwe, kanye nesicelo.Izinto ezivame kakhulu zokuvalwa kwezindebe yirabha ye-nitrile (Buna-N).Le nto isebenza kahle emazingeni okushisa asukela ku -40 kuya ku-275 degrees Fahrenheit.I-Nitrile lip seal ilungele ukusetshenziswa kwezimboni eziningi, kusukela emishinini emisha kuya kwezigxivizo ezishintshayo.Ziyakwazi ukumelana kahle nowoyela, amanzi kanye noketshezi olusebenza ngamanzi, kodwa okwenza lezi zimpawu zihluke yizindleko zazo eziphansi.
Enye inketho engabizi kakhulu i-Viton.Izinga lokushisa layo lingama-40 kuya ku-400 degrees Fahrenheit, kuya ngenhlanganisela ethile.Ama-Viton seal anokumelana kahle nowoyela futhi angasetshenziswa nophethiloli kanye noketshezi lokudlulisela.
Ezinye izinto zokuvala ezingasetshenziswa nge-petroleum zihlanganisa i-Aflas, i-Simiriz, i-carboxylated nitrile, i-fluorosilicone, i-nitrile egcwele kakhulu (HSN), i-polyurethane, i-polyacrylate, i-FEP ne-silicone.Zonke lezi zinto zinezinhlelo zokusebenza ezithile kanye nezigaba zokushisa ezinembile.Qinisekisa ukuthi ucabangela inqubo yakho nendawo yakho ngaphambi kokukhetha noma ukushintsha izinto zokuvala uphawu, njengoba izinto ezifanele zingavimbela ukwehluleka okumba eqolo.
Uma impahla yokuvala isikhethiwe, isinyathelo esilandelayo ukucabangela isakhiwo sophawu.Esikhathini esidlule, ama-lip seal alula ayehlanganisa ibhande ku-axle yesondo.Izindebe zanamuhla zomlomo zihlanganisa izingxenye eziningi ezithinta ukusebenza kwezimpawu.Kunezindlela ezihlukene zokuxhumana, kanye nezimpawu ze-springless kanye ne-spring-loaded.Ama-non-spring seal ngokuvamile awabizi kakhulu futhi ayakwazi ukugcina izinto ezinamathelayo ezifana nogrisi ngesivinini esiphansi se-shaft.Izinhlelo zokusebenza ezijwayelekile zifaka phakathi izinto zokuthutha, amasondo nezinto ezigcotshisiwe.Izigxivizo zasentwasahlobo zivame ukusetshenziswa ngamafutha futhi zingatholakala ezinhlobonhlobo zemishini.
Uma impahla yophawu kanye nomklamo sekukhethiwe, uphawu lomlomo kufanele lufakwe ngendlela efanele ukuze lusebenze ngempumelelo.Kunemikhiqizo eminingi emakethe eyenzelwe ngqo lo msebenzi.Iningi libukeka njengama-bushing kits lapho uphawu lufakwe khona ngqo emgodini.Lawa mathuluzi angasebenza kahle uma ekhethwe ngokucophelela, kodwa izinguqulo eziningi ze-off-the-shelf azisebenzi kahle, ikakhulukazi uma i-shaft isivele ifakiwe.
Kulezi zimo, ngikhetha ukusebenzisa ishubhu elikhulu ngokwanele ukushelela phezu kwe-shaft futhi ngixhumane kahle ne-lip seal housing.Uma ungathola into ongaxhuma kuyo indlu, ungavimbela ukulimala kwendandatho yensimbi engaphakathi exhuma ku-lip seal.Vele uqiniseke ukuthi uphawu lufakwe ngokuqondile futhi ekujuleni okulungile.Ukwehluleka ukubeka uphawu oluqondile ku-shaft kungase kubangele ukuvuza ngokushesha.
Uma unomphini osetshenzisiwe, kungase kube khona indandatho lapho i-lip seal endala yayihlala khona.Ungalokothi ubeke indawo yokuxhumana endaweni yokuxhumana yangaphambilini.Uma lokhu kungenakugwemeka, ungasebenzisa imikhiqizo ethile eshibilika phezu kwe-shaft ukusiza ukulungisa indawo eyonakele.Lokhu kuvame ukushesha futhi ukonga kakhulu kunokushintsha i-shaft.Sicela uqaphele ukuthi uphawu lwe-lip kufanele lufane nosayizi we-bushing ozikhethela.
Lapho ufaka uphawu lomlomo, qiniseka ukuthi umsebenzi wenziwe ngendlela efanele.Ngike ngabona abantu befaka ama-seal besebenzisa i-punch ukuze bangachithi isikhathi esengeziwe bethola ithuluzi elilungile.Ukushaya ngengozi kungase kudabuke impahla yotywino, kubhoboze indlu yophawu, noma kuphoqe isigxivizo endlini.
Qinisekisa ukuthi uthatha isikhathi sokufaka i-lip seal futhi ugcobe i-shaft futhi uyivale kahle ukuvimbela ukudabuka noma ukunamathela.Futhi qiniseka ukuthi uphawu lomlomo luwusayizi olungile.Imbobo kanye ne-shaft kumele kube nokulingana kokuphazamiseka.Ukulinganisa okungalungile kungase kubangele uphawu ukuthi lujikeleze ku-shaft noma luqhelelane nezinto zokusebenza.
Ukuze usize i-lip seal yakho ihlale inempilo ngangokunokwenzeka, kufanele ugcine uwoyela wakho uhlanzekile, upholile, futhi womile.Noma yikuphi ukungcola emafutheni kungangena endaweni yokuxhumana futhi kulimaze i-shaft ne-elastomer.Ngokunjalo, lapho uwoyela eshisa kakhulu, kulapho ukugqokwa kwezimpawu kuzokwanda.I-lip seal nayo kufanele igcinwe ihlanzekile ngangokunokwenzeka.Ukudweba uphawu noma ukungcola kokwakha okuzungezile kungabangela ukushisa okukhulu nokuwohloka ngokushesha kwe-elastomer.
Uma ukhipha i-lip seal futhi ubone imifantu isikwe ku-shaft, lokhu kungase kube ngenxa yokungcola kwezinhlayiya.Ngaphandle kokungenisa umoya omuhle, lonke uthuli nokungcola okungena emishini kungalimaza hhayi kuphela ama-bearings namagiya, kodwa futhi i-shaft ne-lip seal.Yiqiniso, kungcono ngaso sonke isikhathi ukukhipha ukungcola kunokuzama ukukususa.I-grooving kungenzeka futhi uma ukulingana phakathi kwe-lip seal kanye ne-shaft kuminyene kakhulu.
Izinga lokushisa eliphakeme liyimbangela eyinhloko yokuhluleka kwezimpawu.Njengoba izinga lokushisa likhuphuka, ifilimu yokugcoba iba mncane, okuholela ekusebenzeni okomile.Amazinga okushisa aphakeme angabangela nokuthi ama-elastomer aqhekeke noma avuvuke.Kuwo wonke amazinga okushisa angama-57 degrees Fahrenheit, ukuphila kwe-nitrile seal kuncipha ngesigamu.
Izinga likawoyela lingaba esinye isici esithinta impilo yokuvalwa kwezindebe uma liphansi kakhulu.Kulesi simo, uphawu luzoqina ngokuhamba kwesikhathi futhi ngeke lukwazi ukulandela i-shaft, lubangele ukuvuza.
Amazinga okushisa aphansi angabangela izimvu zamanzi zibe brittle.Ukukhetha ama-lubricant afanele kanye nezimpawu kungasiza ukubhekana nezimo ezibandayo.
Ama-seal nawo angahluleka ngenxa yokuphela kwe-shaft.Lokhu kungabangelwa ukungaqondani kahle, amashafu angalingani, amaphutha okukhiqiza, njll. Ama-elastomer ahlukene angakwazi ukumelana namanani ahlukene okuphuma kwamanzi.Ukwengeza isiphethu esiphendukayo kuzosiza ukukala noma yikuphi ukuphuma okulinganisekayo.
Ukucindezela okwedlulele kungenye imbangela engaba khona yokuhluleka kwezindebe zokuvalwa kwezindebe.Uma uke wahamba ngepompo noma nge-transmission futhi wabona uwoyela evuza ezimpahleni, ipani likawoyela lalicindezelwe ngokweqile ngesizathu esithile futhi lavuza laze lafinyelela izinga lokumelana okuncane.Lokhu kungase kubangelwe umshini wokuphefumula ovalekile noma i-cesspool engenawo umoya.Ngezicelo zokucindezela okuphezulu, imiklamo ekhethekile yophawu kufanele isetshenziswe.
Lapho uhlola izindebe zomlomo, bheka ukuguga noma ukuqhekeka kwe-elastomer.Lokhu kuwuphawu olucacile lokuthi ukushisa kuyinkinga.Futhi qiniseka ukuthi i-lip seal isekhona.Ngibone amaphampu amaningana anezimpawu ezingalungile ezifakiwe.Uma kuqalwa, ukudlidliza nokunyakaza kubangela ukuthi uphawu luphume kubhore bese luzungeza ku-shaft.
Noma yikuphi ukuvuza kwamafutha eduze kwesigxivizo kufanele kube ifulegi elibomvu elidinga uphenyo olwengeziwe.Ama-seal agugile angabangela ukuvuza, ama-vents avaliwe, noma ukulimala kwama-radial bearings.
Lapho uhlaziya ukwehluleka kwezindebe zokuvalwa kwezindebe, naka uphawu, i-shaft kanye ne-bore.Lapho uhlola i-shaft, ngokuvamile ungabona indawo yokuxhumana noma yokugqoka lapho i-lip seal ikhona.Lokhu kuzovela njengezimpawu zokugqoka ezimnyama lapho i-elastomer ithinta shaft.
Khumbula: Ukuze ugcine i-lip seal isebenza kahle, ipani likawoyela kufanele ligcinwe lisesimweni esihle.Ngaphambi kokudweba, vala zonke izimpawu, gcina amazinga kawoyela afanele, qinisekisa ukuthi isipholile sikawoyela sisebenza kahle, bese ukhetha umklamo wophawu olufanele nezinto zokwakha.Uma wakha kabusha futhi ufaka okokusebenza kwakho, unganikeza ama-lip seal kanye nezinto zokusebenza ithuba lokulwa ukuze uphile.
I-NINGBO BODI SEALS ingumkhiqizi ochwepheshe weamafutha sealskanye nezingxenye zokuvala ezisezingeni eliphezulu .
