chii chisimbiso chemafuta uye ndeupi musiyano uripo pakati peTC mafuta chisimbiso, TB mafuta chisimbiso, TA mafuta chisimbiso?

Mushini unogadzira mafuta seal

• TC ndiyo nzira yekumiririra yezviyero zvitsva zvenyika.

Japan, Taiwan nedzimwe nzvimbo.FB ndiyo nzira yekumiririra yechiyero chenyika chekare, chine chimiro chakafanana uye zvirimo.Saizvozvo, mazhinji eEuropean zviyero anoshandisa AS kumiririra TC uye FB zvisimbiso zvemafuta.Izvo zviyero zveFB neFC ndezve GB10708.3-189.TC ndiyo nzira yekumiririra yezviyero zvitsva zvenyika, Japan, Taiwan, nedzimwe nzvimbo.TC oiri chisimbiso chinhu chemuchina chinoshandiswa kunama oiri (oiri ndiyo inonyanya kufarirwa mvura mumasisitimu ekutapurirana, zvakare inowanzonzi sechinhu chakajairika chemvura).

(1).FB ndiyo nzira yekumiririra yechiyero chenyika chekare, chine chimiro chakafanana uye zvirimo.

(2).Mazhinji emukati mwero muEurope anoshandisa AS mafuta chisimbiso kumiririra TC uye FB zvisimbiso zvemafuta.

Mafuta zvisimbiso anoshandiswa zvakanyanya munzvimbo dzakasiyana dzemaindasitiri, kunyanya mumichina yemagetsi senge hydraulic masisitimu, injini, pombi, magiya mabhokisi, michina yekufambisa, uye mota.Ivo vanobatsira kuchengetedza zvakajairwa kushanda kwemichina yemidziyo, kuwedzera hupenyu hwesevhisi yemidziyo, kuderedza mari yekugadzirisa, uye kuve nechokwadi chekushanda kwakanaka kwemidziyo.

Magadzirirwo uye kusarudzwa kwezvisimbiso zvemafuta kunofanirwa kufunga nezvezvinhu zvakawanda, zvinosanganisira nharaunda yekushanda, rudzi rwemvura, tembiricha yemhando, zvinodikanwa zvekumanikidza, zvinodikanwa zvekumhanya, etc. Mhando dzakasiyana dzezvisimbiso zvemafuta dzakakodzerwa nemamiriro akasiyana ekushandisa.Mhando dzakajairika dzezvisimbiso zvemafuta dzinosanganisira rotary shaft seals, piston seals, static seals, etc. Zvisimbiso zvemafuta zvinowanzova nemiromo yemukati nekunze, ine muromo wemukati zvakasimba kupikisa shaft inotenderera uye muromo wekunze zvakasimba kune zvakagadziriswa zvikamu.Izvi zvinogadzira chisimbiso chekuvhara nekuda kwekukakavadzana pakati pemiromo yemukati nekunze panguva yekushanda kweshaft inotenderera.

Muchidimbu, zvisimbiso zvemafuta zvinotora basa rakakosha muminda yakaita semichina yeinjiniya, mota, uye zvishandiso zvemaindasitiri, kuve nechokwadi chekushanda kwakajairika kwemichina, kudzivirira kubuda kwemvura uye kusvibiswa kwekunze kupinda, nekudaro kuve nechokwadi chekugadzikana, kuchengetedzeka, uye kuita nemazvo midziyo.

1.Oil chisimbiso chinomiririra nzira

Nzira dzakafanana dzekumiririra:

Oil chisimbiso mhando - yemukati dhayamita - kunze dhayamita - kureba - zvinhu

Semuenzaniso, TC40 * 62 * 12-NBR inomiririra kaviri miromo yemukati skeleton mafuta chisimbiso chine dhayamita yemukati ye40, dhayamita rekunze re62, ukobvu hwegumi nemaviri, uye zvinhu zvenitrile rubhi.

2.Material yemafuta chisimbiso

Nitrile rubber (NBR): kusapfeka-kusagadzikana, mafuta anodzivirira (haagone kushandiswa mune polar media), tembiricha kuramba: -40 ~ 120 ℃.

Hydrogenated nitrile rubber (HNBR): Pfekai kuramba, mafuta kuramba, kuramba kuchembera, tembiricha kuramba: -40 ~ 200 ℃ (yakasimba kupfuura NBR tembiricha kuramba).

Fluorine adhesive (FKM): asidhi uye alkali inodzivirira, mafuta anodzivirira (ese anopokana nemafuta), anodzivirira tembiricha: -20 ~ 300 ℃ (kupokana kwemafuta kuri nani pane maviri ari pamusoro).

Polyurethane rubber (TPU): Pfeka kuramba, kuchembera kuramba, tembiricha kuramba: -20 ~ 250 ℃ (yakanakisa kuchembera kuramba).

Silicone rabha (PMQ): inodzivirira kupisa, isingatonhore, diki compression set, yakaderera mechanical simba, tembiricha kuramba: -60 ~ 250 ℃ (yakanakisa tembiricha kuramba).

Polytetrafluoroethylene (PTFE): Kugadzikana kwakanaka kwemakemikari, kuramba kune akasiyana midhiya akadai seasidhi uye alkali, mafuta, kupfeka kuramba, kupisa kwekushisa kwepamusoro, kusimba kwemagetsi, uye kuzvidzora kwakanaka.

Kazhinji kutaura, zvinhu zvinowanzo shandiswa skeleton mafuta seals nitrile rabha, fluororubber, silicone rabha, uye polytetrafluoroethylene.Nekuda kwekuzvigadzika kwayo kwakanaka, kunyanya kana yawedzerwa nebhuronzi, ine mhedzisiro iri nani, uye ese anoshandiswa kugadzira zvindori zvekuchengeta, zvindori zveGly, uye Stuart seals.

Kusiyanisa muenzaniso we skeleton mafuta chisimbiso

Iyo C-mhando skeleton mafuta chisimbiso inogona kupatsanurwa mumhando shanu: SC mhando, TC mhando, VC mhando, KC mhando, uye DC mhando.Iwo ari single lip yemukati skeleton mafuta chisimbiso, kaviri lip yemukati skeleton mafuta chisimbiso, single lip chitubu chemukati skeleton mafuta chisimbiso, kaviri lip chitubu chemukati skeleton mafuta chisimbiso, uye kaviri lip chitubu chemukati skeleton mafuta chisimbiso.(Tinokurudzira kuti uteerere kune "Mechanical Injiniya" account yepamutemo kuti ubate zvinhu zvakaoma ruzivo uye ruzivo rweindasitiri panguva yekutanga)

Iyo G-type skeleton oil seal ine shinda ine shinda kunze, yakafanana neC-mhando.Inongogadziriswa chete kuti ive ne threaded shape kunze maererano nekombikinoroji, yakafanana nekushanda kweO-ring, iyo isingangosimbisi chisimbiso chekuita asiwo inogadzirisa chisimbiso chemafuta pasina kusunungura.

Iyo B-mhando skeleton mafuta chisimbiso ine inonamira padivi remukati re skeleton kana kuti hapana chinonamira pamativi ese eskeleton.Kusavapo kwekunamatira kuchavandudza kupisa kwekupisa.

Iyo A-mhando skeleton mafuta chisimbiso chisimbiso chemafuta chakafanogadzirwa chine chimiro chakaomarara kana chichienzaniswa nemhando nhatu dziri pamusoro, dzinoratidzwa nekuita zvirinani uye nepamusoro-soro.
