Isingeniso Solwazi Olubanzi Kakhulu Lophawu Lwamafutha

Isingeniso Solwazi Olubanzi Kakhulu Lophawu Lwamafutha.

I-oil seal iyingxenye yomshini esetshenziselwa ukubekwa uphawu, eyaziwa nangokuthi iringi ejikelezayo ye-shaft lip seal.Ingxenye eshayisanayo yomshini ivikelekile ekungeneni kukawoyela ngesikhathi sokusebenza, futhi izigxivizo zikawoyela zisetshenziselwa ukuvimbela ukuvuza kukawoyela emshinini.Ezivamile ama-skeleton oil seal.

1. Indlela yokumelela uphawu lwamafutha

Izindlela zokumela ezivamile:

Uhlobo lophawu lwamafutha - ububanzi bangaphakathi - ububanzi bangaphandle - ukuphakama - impahla

Isibonelo, i-TC30 * 50 * 10-NBR imele isigxivizo samafutha samathambo sangaphakathi sezindebe ezimbili ezinobubanzi obungaphakathi obungu-30, ububanzi obungaphandle obungu-50, nogqinsi lwe-10, olwenziwe ngerabha ye-nitrile.

2. Izinto ze-skeleton oil seal

Irabha ye-Nitrile (NBR): imelana nokugqoka, imelana nowoyela (ayikwazi ukusetshenziswa kumithombo ye-polar), imelana nezinga lokushisa: -40~120 ℃.

Irabha ye-nitrile ene-Hydrogenated (HNBR): Ukumelana nokugqoka, ukumelana nowoyela, ukumelana nokuguga, ukumelana nezinga lokushisa: -40~200 ℃ (kunamandla kunokumelana nezinga lokushisa le-NBR).

Ukunamathiswa kwe-fluorine (FKM): ukumelana ne-asidi ne-alkali, ukumelana nowoyela (ukumelana nawo wonke amafutha), ukumelana nezinga lokushisa: -20~300 ℃ (ukumelana nowoyela okungcono kunalokhu okubili okungenhla).

Irabha yePolyurethane (TPU): Ukumelana nokugqoka, ukumelana nokuguga, ukumelana nezinga lokushisa: -20~250 ℃ (ukumelana nokuguga okuhle kakhulu).

Irabha ye-Silicone (PMQ): ukumelana nokushisa, ukumelana nokubanda, nokucindezelwa okuncane kokushintsha okungapheli namandla aphansi emishini.Ukumelana nezinga lokushisa: -60 ~ 250 ℃ (ukumelana nokushisa okuhle kakhulu).

I-Polytetrafluoroethylene (PTFE): inokuqina okuhle kwamakhemikhali, ukumelana nemithombo yezindaba ehlukahlukene njenge-asidi, i-alkali, namafutha, ukumelana nokugqoka nokumelana nokushisa okuphezulu, amandla aphezulu emishini, kanye nezakhiwo ezinhle zokuzithambisa.

Ngokuvamile, izinto ezivame ukusetshenziselwa ama-skeleton oil seals yirabha ye-nitrile, i-fluororubber, irabha ye-silicone, ne-polytetrafluoroethylene.Ngenxa yezindawo zayo ezinhle zokuzigcoba, ikakhulukazi uma zengezwe ethusi, umphumela ungcono nakakhulu.Zonke zisetshenziselwa ukwenza izindandatho zokugcina, izindandatho ze-Glee, nezinti.

3, Ukuhlukanisa imodeli yohlaka lwamathambouwoyela uphawu

I-C-type skeleton oil seal ingahlukaniswa ngezinhlobo ezinhlanu: uhlobo lukawoyela we-SC, uhlobo lwe-T Coi seal, uhlobo lukawoyela we-VC, uhlobo lukawoyela we-KC, kanye nohlobo lukawoyela we-DC.Ziyi-single lip inner skeleton oil seal, i-double lip inner skeleton oil seal, i-single lip spring free inner skeleton oil seal, i-double lip spring free inner skeleton oil seal, kanye ne-double lip spring free inner skeleton oil seal.(Sincoma ukuthi unake i-akhawunti esemthethweni ethi “Mechanical Engineer” ukuze ubambe ulwazi lwezimpahla ezomile nolwazi lwemboni ngesikhathi sokuqala)

I-G-type skeleton oil seal inomumo oyintambo ngaphandle, okuwuhlobo olufanayo nohlobo lwe-C.Kodwa-ke, iyalungiswa ukuze ibe nomumo onentambo ngaphandle enqubweni, ofana nomsebenzi we-anO-ring, okungagcini nje ukuthuthukisa umphumela wokuvala kodwa futhi kusiza ukulungisa uphawu lwamafutha kusukela ekuthukululeni.

I-B-type skeleton oil seal inezinto ezinamathelayo ohlangothini lwangaphakathi lohlaka lwamathambo noma akukho okunamathelayo ngaphakathi noma ngaphandle kwamathambo.Ukungabikho kwezinto zokunamathela kuzothuthukisa ukusebenza kokukhipha ukushisa.

I-A-type skeleton oil seal iyisivalo sikawoyela esihlanganisiwe esinesakhiwo esiyinkimbinkimbi uma siqhathaniswa nezinhlobo ezintathu ezingenhla, ezibonakala ngokusebenza okungcono nokucindezela okuphezulu.
