Izinga lokushisa eliphezulu&nokugqoka i-PTFE oil seal
Izinzuzo ze-PTFE oil seal
1. Ukuzinza kwamakhemikhali: cishe konke ukumelana namakhemikhali, i-asidi eqinile, isisekelo esiqinile noma i-oxidant eqinile kanye ne-organic solvents ayithinteki.
2. Ukuzinza kwe-thermal: izinga lokushisa lokuqhekeka lingaphezu kuka-400 ℃, ngakho-ke lingasebenza ngokujwayelekile ebangeni elingu -200℃350℃.
Ukumelana nokugqokwa okungu-3: I-PTFE i-coefficient yokungqubuzana kwezinto iphansi, ingu-0.02 kuphela, ingu-1/40 werabha.
4. Self-lubrication: PTFE impahla has omuhle kakhulu self-lubrication ukusebenza, cishe zonke izinto viscous abakwazi ukunamathela ebusweni.
Yiziphi izinzuzo ze-PTFE oil seal uma kuqhathaniswa nophawu lwamafutha enjoloba ajwayelekile?
1. I-Ptfe oil seal iklanywe ngamandla odebe olubanzi ngaphandle kwentwasahlobo, engasebenza ngokujwayelekile ngaphansi kwezimo eziningi zokusebenza;
2. Lapho i-shaft iphenduka, ikhiqiza ngokuzenzakalelayo ukusunduza kwangaphakathi (ukucindezela kuphezulu kunophawu lwamafutha enjoloba evamile), okungavimbela ukugeleza koketshezi;
3. I-Ptfe oil seal ingafanelana nowoyela noma indawo yokusebenza yamafutha amancane, izici zokungqubuzana okuphansi ngemuva kokuvalwa, uma kuqhathaniswa nophawu lwamafutha enjoloba olujwayelekile lusetshenziswa kabanzi;
4. Izimpawu ze-Ptfe zingavala amanzi, i-asidi, i-alkali, i-solvent, igesi, njll.;
5.PTFE uwoyela uphawu ingasetshenziswa at lokushisa ephakeme 350 ℃;
6. I-PTFE oil seal ingamelana nomfutho ophezulu, ingafinyelela ku-0.6~2MPa, futhi ingamelana nezinga lokushisa eliphezulu nesivinini esikhulu.
Indawo yokusebenzela
Isicelo
ama-excavators, izinjini, imishini yemishini yobunjiniyela, amaphampu e-vacuum, izando zokuchoboza, imishini yokwelapha amakhemikhali kanye nochwepheshe abahlukahlukene, imishini ifaneleka ngokukhethekile uphawu lwamafutha enjoloba yendabuko ayikwazi ukuhlangabezana nesicelo.
