U ka khetha lesale la ho tiisa joang bakeng sa sistimi ea hydraulic?
1. NBR nitrile sealing ring e loketse ho sebelisoa ka oli ea petroleum hydraulic oil, ethylene glycol hydraulic oil, diester lubricating oli, peterole, metsi, mafura a silicone, oli ea silicone le mecha e meng ea litaba. Ke tiiso ea rabara e sebelisoang ka ho fetisisa le e theko e tlaase ka ho fetisisa. Ha e loketse ho sebelisoa lihlapolli tsa polar tse kang ketone, ozone, nitrohydrocarbons, MEK le chloroform. Mocheso o tloaelehileng oa tšebeliso ke -40 ~ 120 ℃. Ea bobeli, HNBR hydrogenated nitrile sealing ring e na le ts'ebetso e ntle haholo ea ho hanyetsa kutu, ho hanyetsa meokho le litšoaneleho tsa deformation, ho hanyetsa ozone, ho hanyetsa khanya ea letsatsi, ho hanyetsa boemo ba leholimo ho lokile. Ho hanyetsa ho apara ho molemo ho feta rabara ea nitrile. E loketse metjhini e hlatswang, disistimi tsa dienjene tsa makoloi le disistimi tsa sehatsetsi tse sebedisang sehatsetsi se setjha se baballang tikoloho R134a. Ha e khothalletsoe ho sebelisoa ho lino tse tahang, li-ester, kapa litharollong tse nkhang hamonate. Mocheso o tloaelehileng oa tšebeliso ke -40 ~ 150 ℃. Taba ea boraro, FLS fluorine silicone rabara sealing ring e na le melemo ea rabara ea fluorine le rabara ea silicone, ho hanyetsa oli, ho hanyetsa solvent, ho hanyetsa oli ea mafura le ho hanyetsa mocheso o phahameng le o tlaase ho molemo. E hanyetsana le tlhaselo ea oksijene e nang le metsoako, hydrocarbon e nkhang hamonate e nang le metsoako le chlorine e nang le metsoako. Ka kakaretso e sebelisoa bakeng sa lifofane, lifofane le merero ea sesole. Ho pepesehela li-ketone le marotholi a brake ha ho khothalletsoe. Mocheso o tloaelehileng oa tšebeliso ke -50 ~ 200 ℃.
2, ho phaella litlhoko tse akaretsang tsa thepa ea lesale la ho tiisa, lesale la ho tiisa le lona le lokela ho ela hloko maemo a latelang: (1) elastic le e tsitsitseng; (2) Matla a loketseng a mochini, ho kenyelletsa matla a ho atolosa, bolelele le matla a ho taboha. (3) Ts'ebetso e tsitsitse, ha ho bonolo ho ruruha bohareng, 'me phello ea mocheso oa mocheso (Joule effect) e nyenyane. (4) Ho bonolo ho sebetsa le ho bopeha, 'me e ka boloka boholo bo nepahetseng. (5) ha e senya sebaka sa ho kopana, ha e silafatse bohareng, joalo-joalo Thepa e loketseng ka ho fetisisa le e sebelisoang ka ho fetisisa ho finyella litlhoko tse ka holimo ke rabara, kahoo lesale la ho tiisa hangata le entsoe ka thepa ea rabara. Ho na le mefuta e mengata ea rabara, 'me ho na le mefuta e mengata ea rabara e ncha kamehla, moralo le khetho, e lokela ho utloisisa litšobotsi tsa rabara e fapaneng, khetho e utloahalang.
3. Melemo
(1) Rela ea tiiso e lokela ho ba le ts'ebetso e ntle ea ho tiisa khatellong ea ho sebetsa le mocheso o itseng, 'me e ka ntlafatsa ka bo eona ts'ebetso ea ho tiisa ka ho eketseha ha khatello.
(2) Khohlano pakeng tsa sesebelisoa sa ho tiisa le likarolo tse tsamaeang e lokela ho ba nyenyane, 'me coefficient ea khohlano e lokela ho ba e tsitsitseng.

(4) Sebopeho se bonolo, se bonolo ho se sebelisa le ho se boloka, e le hore lesale la ho tiisa le be le nako e telele. Tšenyo ea selikalikoe sa tiiso e tla baka ho lutla, e leng se tla baka tšenyo ea mecha ea litaba e sebetsang, tšilafalo ea mochini le tikoloho, esita le ho baka ho hloleha ha ts'ebetso ea mochini le likotsi tsa motho ka mong. Ho tsuba ka hare ho tla etsa hore katleho ea volumetric ea tsamaiso ea hydraulic e theohe haholo, 'me khatello e hlokahalang ea ho sebetsa e ke ke ea finyelloa, kapa esita le mosebetsi o ke ke oa etsoa. Likaroloana tse nyane tsa lerōle tse hlaselang sistimi li ka baka kapa tsa mpefatsa ho senyeha ha lipara tsa likhohlano tsa likarolo tsa haeteroliki, e leng se lebisang ho lutlang. Ka hona, litiiso le lisebelisoa tsa ho tiisa ke karolo ea bohlokoa ea lisebelisoa tsa hydraulic. Ho tšepahala le bophelo ba tšebeletso ea mosebetsi oa eona ke pontšo ea bohlokoa ea ho lekanya boleng ba tsamaiso ea hydraulic.
Zhuo Meng Shanghai Auto Co., Ltd. e ikemiselitse ho rekisa likarolo tsa koloi tsa MG&MAUXS tse amohelehang ho li reka.
