Mokhoa oa ho khetha hose e nepahetseng ea hydraulic bakeng sa lits'ebetso tsa hau:
Li-hoses tsa Hydraulicli bohlokoa bakeng sa lits'ebetso tse ngata tsa indasteri le tsa khoebo, tse ts'ehetsang ts'ebetso e bolokehileng le e sebetsang hantle.
Ho na le mefuta e mengata e fapaneng e fumanehang bakeng sa lits'ebetso tsohle - ho tloha ho liphaepe tse hanyetsanang le lik'hemik'hale le likhatello tse phahameng ho ea ho tse tiileng hantle bakeng sa ho sebelisoa libakeng tse nang le tšubuhlellano kapa tse kotsi.
Ho khetha le ho kenya hose e nepahetseng, ho bohlokoa ho utloisisa metheo ea li-hydraulic hoses le lintlha tse hlakileng tsa ts'ebeliso ea hau e hlokahalang:
Hose ea hydraulic ke eng?
Hose ea hydraulic ke hose e ikhethang e sebelisoang litsing tsa indasteri le tsa khoebo.Li sebetsa 'moho le mochini oa hydraulic, li hokahanya li-valve, lisebelisoa le li-activator tse lumellang maro kapa likhase ho phalla ho tloha karolong e' ngoe ho ea ho e 'ngoe.
Sebopeho sa hose ea Hydraulic:
Li-hoses tsa Hydraulic li na le tube e ka hare ka hare ho lera e matlafalitsoeng le likarolo tse ka ntle tse sireletsang.Thepa e ka hare ea tube e khethoa hore e lumellane le maro, mocheso, likhatello le maikutlo a hlokahalang hose.Likarolo tse ka ntle li hahiloe ho lumellana le matla le ho tšoarella ho hlokahalang ha hose sebakeng sa eona sa ts'ebetso.Sebopeho sa hose ea hydraulic e tlameha ho ba matla ka ho lekana ho mamella likhatello tsa kahare le kantle.
Theropo e ka hare e ka etsoa ka rabara ea maiketsetso, PTFE, kapa thermoplastics, ho itšetlehile ka thepa le likhatello tsa maro kapa likhase tse ka hare.Matlafatso a ka etsoa ka terata e le 'ngoe, e mengata e mengata ea terata e lohiloeng, khoele ea masela kapa terata ea maqeba a spiral.Lera le sireletsang le ka etsoa ka lisebelisoa tse ngata tse hanyetsanang, tse lelekang, le tse tenyetsehang, ho itšetlehile ka matla a tikolohong e ka ntle.
Li-hoses tsa hydraulic li sebelisetsoa eng?
Li-hose tsa Hydraulic li bohlokoa liindastering tse ngata, ho kenyelletsa taolo ea litšila, tlhahiso, likhoebo tsa temo le tsa meriana.Li ka fumanoa nthong e 'ngoe le e 'ngoe ho tloha ho likoloi le limela ho ea ho mechine e khethehileng kapa mela ea tlhahiso, e tsamaisang mekhoa e mengata e kenyeletsang ho hlatsoa khatello e phahameng, lithapo tsa khase le lipente tsa pente.
Tšireletseho ea hose ea Hydraulic:
Kaha li-hose tsa haeteroliki li sebelisoa liindastering tsa bohlokoa kapa libakeng tse kotsi, ho bohlokoa hore ho etsoe khetho e nepahetseng ea sehlahisoa, ho kopanya lithapo le tlhokomelo.Sena se fokotsa kotsi ea likotsi tsa 'mele, tsa ts'ebetso, kapa tsa tikoloho kapa ho fokotsa nako e theko e boima.
Mefuta e fapaneng ea li-hydraulic hose ke efe?
Ho na le mefuta e mengata ea li-hose tsa hydraulic tse fumanehang, tse loketseng mefuta e mengata ea likhatello, litšusumetso le mocheso nakong ea kopo.
Li-Hoses li ka khetholloa ka lihlopha tsa tsona tse ka ntle, tse lokelang ho khethoa bakeng sa ho tšoarella khahlanong le likhatello tsa ho sebetsa le tikoloho ea ka ntle.Tsena li kenyelletsa:
Braided Hose - Hose e nang le maemo a mangata a khatello e phahameng e sebelisoang lits'ebetsong tse akaretsang tsa indasteri 'me e loketse hoo e batlang e le mefuta eohle ea lisebelisoa tsa hydraulic tse nang le petroleum le metsi a thehiloeng metsing.
Spiral Hose - Hose e feto-fetohang ea khatello e phahameng e loketseng ho sebelisoa ka tšusumetso e phahameng le khatello ea ho sebetsa ho fihla ho 50.0MPa, joalo ka hamore hydraulics.
Hose ea Thermoplastic - Hose e feto-fetohang haholo e nang le katoloso e tlase ea molumo, e fanang ka linako tse ntle tsa karabelo ea haeteroliki mme e khona ho mamella khatello ho fihla ho 80.0MPa.
P.T.FE- Hose e hanyetsanang haholo, e khonang ho mamella mefuta e mengata ea lik'hemik'hale ka lebaka la thepa e phahameng e sa tsitsang le ho se chese, e etsang hore e be e loketseng bakeng sa likopo tse mabifi.
Hose e nang le khatello e tlase - Hose e lohiloeng ka masela, e fanang ka maemo a bonolo bakeng sa lisebelisoa tse bobebe empa e sitoa ho mamella likhatello tse phahameng.
Hose ea tšepe e entsoeng ka terata e sa hloekang - Hose e boima e tšoarellang ka ho lekaneng bakeng sa lisebelisoa tse mabifi le ho khona ho mamella maemo a feteletseng a ka ntle.
Ho boetse ho na le mefuta e fapaneng ea li-tubes tse ka hare, ho kenyelletsa:
Rabara e hanyetsanang le oli ea maiketsetso - E loketse maro a tlhaho a tlhaho le a maiketsetso.
Polyester - E loketse metsi le likhase tsa indasteri.
Polyamide - E hanyetsana haholo le maro a joalo ka lipente, li-solvents tse nang le chlorinated le lik'hemik'hale tse ling.
P.TFE - E hanyetsana haholo bakeng sa tšebeliso ea lik'hemik'hale le lihlapolli.
MPa ke eng?Megapascal (MPa) ke metric ea ho lekanya khatello.E sebelisetsoa ho bonts'a mekhahlelo ea khatello le litekanyetso tsa litsamaiso tsa hydraulic, kaha e lekanya litekanyetso tse kholoanyane - 1 megapascal = 1,000,000 pascals kapa 10 Bar.
Tekanyetso ea hose ea Hydraulic:
Li-hose tsa Hydraulic li laoloa ke bobeli ba indasteri le litekanyetso tsa machaba - SAE Standards (e behiloeng ke Mokhatlo oa Baenjiniere ba Likoloi), le Melao ea EN - ho netefatsa hore ba lumellana le litekanyetso tsa polokeho le ts'ebetso.
Nka khetha hose e nepahetseng joang?
Khetho e nepahetseng ea sehlahisoa le ho kopanya li-hose ho bohlokoa molemong oa ts'ebetso e bolokehileng, e sebetsang ea mochini le lits'ebetso.Lintlha tse latelang tsa ts'ebeliso le ts'ebeliso li lokela ho nahanoa ha u khetha hose ea hydraulic:
Mefuta ea Fluid / Gas - Haholo-holo, maro kapa likhase tse tla phalla ka har'a hose, le ho tsepamisa mohopolo oa tsona, li tlameha ho tsejoa le ho utloisisoa ho fumana matla a hlokahalang a tube e ka hare.Ka mohlala, lihlapolli tse mabifi li hloka li-tubes tse ka hare tse hanyetsanang haholo.Likhase li ka 'na tsa hloka ho hlajoa ka pin ea sekoahelo
Mocheso - Ka mor'a moo mocheso o sebetsang oa maro kapa likhase o tlameha ho tsejoa.Sena se etsa bonnete ba hore mocheso o phahameng o ke ke oa nyenyefatsa tube e ka hare, kapa mocheso o tlase o ke ke oa sitisa ts'ebetso ea ona joalo ka kotopo.Ho phaella moo, mocheso o ka ntle o potolohileng hose o tlameha ho tsejoa, ho netefatsa hore hose e ka sebetsa ka ho lekaneng ka har'a mocheso o feteletseng kapa e mamella phapang leha e le efe ea mocheso.
Khatello - Likhatello tseo metsi kapa likhase li tla phalla ka har'a hose li tla etsa qeto ea matla a hlokahalang a likarolo tsohle tsa kopano ea hose, ho kenyeletsa le monyetla oa ho ba le li-spikes tsa khatello.Maemo ana a ts'ebetso a tla laela ho hanyetsa ka hare le ka ntle ho hlokahalang.
Boholo - Boholo ba hose ea hau bo hloka ho ikarabella bakeng sa bophara bo lekaneng le bolelele bo loketseng.Bophara ba ka hare bo tla laoloa ke likhatello tsa ka hare ha bophara ba ka ntle bo laoloa ke boemo ba tšireletso bo hlokahalang kapa sebaka se fumanehang hammoho le radius ea bend e hlokahalang.Bolelele ka kakaretso bo tla itšetleha ka sebaka se pakeng tsa likarolo le ho feto-fetoha ho hlokahalang ha hose nakong ea tšebeliso.Sekhahla sa phallo se hlokahalang se tla boela se lekanye bolelele le bophara ba hose
Lipheletso & Maqhama - Khetho e phethahetseng ea li-hose e kenyelletsa kopano e nepahetseng ea li-hose ho ea lipheletsong le li-couplings, ho netefatsa ho tšoarella le ho fetoha habonolo.Khoele e nepahetseng ea ho nyalana bakeng sa lipheletsong e tla thibela ho lutla ha ho tiisitsoe.Tsena li bohlokoa ho fokotsa kotsi ea ho phatloha ho ka bang kotsi kapa ho khaoha.Etsa bonnete ba hore likhokahano tsohle tsa ho qetela li lekoa ka botlalo 'me li amohetsoe ho sebelisoa ha u khetha hose
Ho fumaneha le Litšenyehelo - Hose ea ho qetela ea hydraulic e tlameha ho lumellana le tekanyetso ea hau, bokhoni ba ts'ebetso, le kemiso ea tlhokomelo ho netefatsa katleho le ts'ebetso ea ts'ebetso.Ka mohlala, haeba ho loketse kapa ho hlokahala, likarolo tsa kopo ea hose li ka fetoloa hore li lumellane le kopano e tloaelehileng ea hose e fumanehang habonolo kapa e bolokang chelete e ngata.
E hlometse ka lintlha tsohle tse ka holimo, ho ka khethoa hose e nepahetseng ea hydraulic bakeng sa lits'ebetso tsa hau.
