Intshayelelo kolona Lwazi luBanzi lweOli yeSitywina.

I-oyile yokutywinwa licandelo lomatshini elisetyenziselwa ukutywina, okwakwaziwa njengeringi yokutywina yomlomo weshaft ejikelezayo.Inxalenye yokukhuhla koomatshini ikhuselwe ekungeneni kweoli ngexesha lokusebenza, kwaye izitywina zeoyile zisetyenziselwa ukuthintela ukuvuza kweoli koomatshini.Ezona ziqhelekileyo zizitywina zeoyile zamathambo.

I-1, indlela yokubonakalisa uphawu lwe-oyile

Iindlela zokubonisa eziqhelekileyo:

Uhlobo lwe-oyile yetywina - i-diameter yangaphakathi - i-diameter yangaphandle - ukuphakama - impahla

Umzekelo, i-TC30 * 50 * 10-NBR imele i-double lip inner skeleton oil seal kunye ne-diameter yangaphakathi ye-30, i-diameter yangaphandle ye-50, kunye nobukhulu be-10, eyenziwe ngerubha ye-nitrile.

2, Izinto ze-skeleton oil seal

Irabha ye-Nitrile (NBR): i-oil-resistant-resistant (ayinakusetyenziswa kwimidiya ye-polar), ukumelana nobushushu: -40 ~ 120 ℃.

Irabha ye-nitrile ene-Hydrogenated (HNBR): Ukumelana nokunxiba, ukumelana ne-oyile, ukuxhathisa ukuguga, ukumelana nobushushu: -40 ~ 200 ℃ (yomelele kune-NBR ukumelana nobushushu).

I-adhesive ye-fluorine (FKM): i-asidi kunye ne-alkali ukumelana, i-oyile iyaxhathisa (ixhathise kuzo zonke i-oyile), ukumelana nobushushu: -20 ~ 300 ℃ (ingcono ukumelana neoli kunezi zimbini zingasentla).

Irabha yePolyurethane (TPU): Ukumelana nokunxiba, ukuxhathisa ukuguga, ukumelana nobushushu: -20 ~ 250 ℃ (ukumelana nokuguga okugqwesileyo).

Irabha ye-Silicone (PMQ): ukumelana nobushushu, ukumelana nokubanda, kunye ne-deformation encinci yokunyanzeliswa kwesigxina kunye namandla aphantsi omatshini.Ukumelana nobushushu: -60 ~ 250 ℃ (ukumelana nobushushu obugqwesileyo).

I-Polytetrafluoroethylene (PTFE): inozinzo oluhle lweekhemikhali, ukuchasana neendaba ezahlukeneyo ezifana ne-asidi, i-alkali, kunye ne-oyile, ukumelana nokunxiba kunye nokumelana nobushushu obuphezulu, amandla aphezulu omatshini, kunye neempawu ezintle zokuzithambisa.

Ngokubanzi, izinto eziqhelekileyo ezisetyenziselwa ukutywinwa kweoyile ye-skeleton yirabha ye-nitrile, i-fluororubber, irabha ye-silicone, kunye ne-polytetrafluoroethylene.Ngenxa yezinto ezintle zokuzithambisa, ngakumbi xa zongezwa kwi-bronze, umphumo ungcono nakakhulu.Zonke zisetyenziselwa ukwenza amakhonkco okugcina, amakhonkco e-Glee, kunye nezinti.

3, Ukwahlula imodeli yamathamboitywina yeoli

I-C-uhlobo skeleton oil seal inokwahlulwa ibe ziindidi ezintlanu: SC uhlobo ioli itywina, T Coi uhlobo itywina, VC oyile itywina uhlobo, KC oyile itywina uhlobo, kunye nodidi olitywina DC.Ziyi-oyile yomlomo omnye wamathambo angaphakathi, i-oyile ye-skeleton ephindwe kabini, i-oyile yomlomo omnye, i-oyile yomlomo omnye, i-oyile ye-skeleton yangaphakathi, i-oyile ye-oyile ephindwe kabini, kunye ne-oyile ye-oyile ye-skeleton ephindwe kabini.(Sincoma ukuba ubeke ingqalelo kwi-akhawunti esemthethweni ye-"Mechanical Engineer" ukuze ubambe ulwazi lwempahla eyomileyo kunye nolwazi lweshishini okokuqala)

I-G-type skeleton oil seal inemilo ene-threaded ngaphandle, eluhlobo olufanayo nohlobo lwe-C.Nangona kunjalo, iyalungiswa ukuze ibenemilo enemisonto ngaphandle kwinkqubo, efana nomsebenzi weO-ring, engagcini nje ukunyusa umphumo wokutywinwa kodwa inceda ukulungisa i-oil seal ekukhululweni.

I-oyile ye-B-type skeleton itywina inezinto ezincamathelayo kwicala langaphakathi le-skeleton okanye akukho nto yokubambelela ngaphakathi okanye ngaphandle kwe-skeleton.Ukungabikho kwezinto zokubambelela kuya kuphucula ukusebenza kokutshatyalaliswa kobushushu.

I-A-type skeleton oil seal sisitywina se-oyile esidityanisiweyo esinesakhiwo esintsonkothileyo xa kuthelekiswa nezi ntlobo zintathu zingasentla, ezibonakaliswa ngokusebenza ngcono kunye noxinzelelo oluphezulu.
