Thepa ea rabara e sebelisoang haholo bakeng salitiiso tsa haeterolikike rabara ea nitrile NBR.Ho phaella moo, ha ho na le litlhoko tse khethehileng tsa ho hanyetsa mocheso le ho hanyetsa oli, fluororubber e ka sebelisoa;Ha ho na le litlhoko tse khethehileng tsa ho hanyetsa ho apara le ho hanyetsa khatello, AU / EU (rabara ea polyurethane) e ka khethoa.
1. Mefuta ea mecha ea phatlalatso e sebetsang bakeng sa litiiso tsa hydraulic
Na mokhoa oa ho sebetsa oa hydraulic seals ke metsi kapa khase?Haeba e le mokelikeli, ho lumellana pakeng tsa mokelikeli le thepa ho lokela ho nkoa;Khase e boetse e hloka ho nahana ka ho lumellana ha thepa le mafura le mafura;Khase le khatello e mpe ea tiiso e boetse e lokela ho ela hloko phefumoloho.Haeba thepa ea ho tiisa e lumellana le mokelikeli oa ho tiisa, e ka etsa hore ntho ea ho tiisa e atolohe kapa e fokotsehe, e leng se lebisang ho hloleha ha mekhahlelo ea pele ea tšebeliso.Ho atolosoa ha tiiso ho baka keketseho ea ho hanyetsa likhohlano hape ho etsa hore tiiso e theohe.Ho fokotseha ha ntho e tiisang ho ka baka phokotseho ea ho jara esale pele, ho fokotseha ha matla a matšeliso a eccentricity, 'me qetellong ho lebisa ho lutla.
2. Ho tiisa ka matla kapa ho tsitsitseng
Litiiso tse matla li na le litlhoko tse tsamaellanang bakeng sa ho hohlana le ho apara ha lisebelisoa, 'me lisebelisoa tse nang le li-coefficients tse nepahetseng li lokela ho khethoa ho latela boholo ba lebelo la ho sisinyeha.E le hore u finyelle bophelo bo lekaneng ba tšebeletso, ho boetse hoa hlokahala ho khetha ho hanyetsa ho apara ha thepa e thehiloeng ho lebelo le ho otloa ha motsamao.Ha ho na le tlhokahalo bakeng sa ts'ebetso ea lebelo le tlaase, tlhokomelo e khethehileng e lokela ho lefshoa ho boholo ba coefficient ea khohlano ea thepa le phapang pakeng tsa li-coefficients tse matla le tse tsitsitseng.
3. Mofuta oa sebopeho sa ntho ea ho tiisa (e ntšitsoeng kapa e bōpehileng joaloka molomo)
Molao-motheo oa ts'ebetso oa ho tiisa o fapana le mefuta e fapaneng ea meralo, eo ka mokhoa o ke keng oa qojoa e hlokang thepa e fapaneng ea mochini joalo ka elasticity, matla le sekhahla sa deformation ea thepa.
4. Mocheso o sebetsang oa litiiso tsa hydraulic
Mocheso o sebetsang oa mefuta e fapaneng ea li-rubber tsa ho tiisa le li-plastiki li fapana haholo.Ha u khetha lisebelisoa, ho hlokahala hore u utloisise ka nepo mocheso o sebetsang oa likarolo tsa ho tiisa, haholo-holo tikoloho ea mocheso e tlaase eo likarolo li leng ho eona, 'me u khethe lisebelisoa ho latela;Kapa laola ho phahama ha mocheso oa likarolo, litsamaiso, le litiiso tse ipapisitseng le mocheso o sebetsang oa thepa.Khetha lisebelisoa tse ka mamellang mocheso oa tsona o phahameng ka ho fetisisa.
- Khatello ea ho sebetsa ea litiiso tsa hydraulic
Khatello ea ho sebetsa ke eona parameter e ka sehloohong ea ho sebetsa ea li-hydraulic le pneumatic systems, tse ka fapaneng pakeng tsa 1-400MPa kapa mefuta e mengata.Khatello ea khatello ea thepa e lokela ho ikamahanya le litlhoko tsa khatello ea ho sebetsa.
6. Na sebaka se sebetsang sa li-hydraulic seal se silafalitsoe Haeba ho na le tšilafalo ea lerōle sebakeng sa mosebetsi, e tla mpefatsa ho roala ha thepa, 'me ho hanyetsa ho apara ha thepa ho lokela ho ntlafatsoa.Na karolo e tsitsitse kapa e sisinyeha nakong ea ts'ebetso.Haeba e sebetsa tlas'a vibration. Maemo, thepa e lokela ho ba le elasticity e lekaneng ho lefella ho se lekane ho tiisa khatello ea maikutlo e bakoang ke ho falla ho bakoang ke ho sisinyeha.
