Unokukhetha njani umsesane wokutywina wenkqubo yehydraulic?
1. I-NBR nitrile irubha yokutywinwa ilungele ukusetyenziswa kwi-petroleum hydraulic oil, i-ethylene glycol hydraulic oil, i-diester lubricating oil, i-petroli, amanzi, i-silicone grease, ioli ye-silicone kunye neminye imithombo yeendaba.Yeyona isetyenziswa kakhulu kwaye inexabiso eliphantsi lerabha itywina.Ayifanelekanga ukusetyenziswa kwi-solvents ye-polar njenge-ketones, i-ozone, i-nitrohydrocarbons, i-MEK kunye ne-chloroform.Uluhlu lobushushu bokusetyenziswa ngokubanzi yi -40~120 ℃.Okwesibini, i-HNBR hydrogenated nitrile irabha yokutywina iringi inokumelana nokugqwesa okugqwesileyo, ukuxhathisa ukukrazuka kunye neempawu ze-deformation deformation, ukumelana ne-ozone, ukumelana nokukhanya kwelanga, ukuxhathisa kwemozulu kulungile.Ukumelana nokunxiba ngcono kunerabha ye-nitrile.Ifanele oomatshini bokuhlamba, iisistim zeenjini zeemoto kunye neenkqubo zokukhenkcisa kusetyenziswa ifriji entsha ehambelana nokusingqongileyo i-R134a.Ayikhuthazwa ukuba isetyenziswe kwii-alcohols, ii-esters, okanye izisombululo ezinuka kamnandi.Uluhlu lobushushu bokusetyenziswa ngokubanzi yi -40~150 ℃.Okwesithathu, i-FLS fluorine i-silicone i-rubber yokutywina i-rubber inenzuzo yerubha ye-fluorine kunye ne-silicone irabha, ukuxhathisa i-oyile, ukuxhathisa i-solvent, ukumelana ne-oyile ye-fuel kunye nokumelana nokushisa okuphezulu kunye nokuphantsi kulungile.Iyakwazi ukumelana nokuhlaselwa kweoksijini equlethe iikhompawundi, i-hydrocarbon enuka kamnandi equlethe izinyibilikisi kunye neklorini equlethe izinyibilikisi.Ngokuqhelekileyo isetyenziselwa ukuhamba ngeenqwelomoya, i-aerospace kunye neenjongo zomkhosi.Ukuvezwa kwi-ketones kunye ne-brake fluids akukhuthazwa.Uluhlu lobushushu bokusetyenziswa ngokubanzi ngu -50 ~ 200 ℃.
2, ukongeza kwiimfuno eziqhelekileyo zezinto zokutywina, umsesane wokutywina kufuneka uphinde ubeke ingqalelo kule miqathango ilandelayo: (1) i-elastic kunye ne-resilient;(2) Amandla afanelekileyo omatshini, kubandakanywa amandla okwandisa, ukunyusa kunye namandla okukrazula.(3) Ukusebenza kuzinzile, akulula ukudumba phakathi, kunye nefuthe le-thermal contraction effect (i-Joule effect) incinci.(4) Kulula ukusetyenzwa kunye nokumila, kwaye inokugcina ubungakanani obuchanekileyo.(5) ayigqwali indawo yokudibanisa, ayingcolisi i-medium, njl njl. Eyona nto ifanelekileyo kunye neyona nto isetyenziswa ngokuqhelekileyo ukuhlangabezana neemfuno ezingentla yirabha, ngoko ke umsesane wokutywina wenziwa kakhulu ngezinto zerabha.Kukho iintlobo ezininzi zeerubha, kwaye kukho iintlobo ezintsha zerubha rhoqo, ukuyila kunye nokukhethwa, kufuneka kuqondwe iimpawu zeerubha ezahlukeneyo, ukhetho olufanelekileyo.
3. Izinto eziluncedo
(1) Umsesane wokutywina kufuneka ube nokusebenza kakuhle kokutywinwa kuxinzelelo lokusebenza kunye noluhlu oluthile lobushushu, kwaye lunokuphucula ngokuzenzekelayo ukusebenza kokutywinwa ngokunyuka koxinzelelo.
(2) Ingxabano phakathi kwesixhobo sokutywina kunye neendawo ezihambayo kufuneka zibe zincinci, kwaye i-coefficient of friction kufuneka izinzile.
(3) Umsesane wokutywina unokumelana nokugqwala okuqinileyo, akukho lula ukuguga, unobomi obude bokusebenza, ukuxhathisa kokunxiba kakuhle, kwaye unokubuyiselwa ngokuzenzekelayo emva kokunxitywa kwinqanaba elithile.
(4) Isakhiwo esilula, kulula ukuyisebenzisa kunye nokugcina, ukwenzela ukuba umsesane wokutywina unobomi obude.Umonakalo womsesane wetywina uya kubangela ukuvuza, okukhokelela kwinkcitho yemithombo yeendaba esebenzayo, ungcoliseko lomatshini kunye nokusingqongileyo, kwaye kubangele ukusilela ekusebenzeni koomatshini kunye nezixhobo zeengozi zomntu.Ukuvuza kwangaphakathi kuya kubangela ukuba ukusebenza kwe-volumetric ye-hydraulic system yehle ngokukhawuleza, kwaye uxinzelelo olufunekayo olusebenzayo alukwazi ukufikelela, okanye nokuba umsebenzi awunakwenziwa.Amasuntswana othuli oluncinane ahlasela inkqubo anokubangela okanye enze mandundu ukuguga kwezibini zokukhuhlana zamalungu olwelo lwamanzi, okukhokelela ngakumbi ekuvuzeni.Ke ngoko, izitywina kunye nezixhobo zokutywina ziyinxalenye ebalulekileyo yezixhobo zehydraulic.Ukuthembeka kunye nobomi benkonzo yomsebenzi wayo luphawu olubalulekileyo lokulinganisa umgangatho we-hydraulic system.
