Ndeupi hwaro hwekuwana bhora vharafu sealing?

Kuiswa chisimbiso kwebhora mavharuvhukunyanya inotsamira pakusimba kwakasimba pakati pebhora nechigaro chevharuvhu. Iyo yekuisa chisimbiso uye nzira yekushandisa ndeiyi inotevera:

Chisimbiso chimiro che abhora vharafuinotenderera dhizaini yekukodzera pakati pebhora nechigaro chevharuvhu. Kana vheji yebhora iri munzvimbo yakavharwa, iyo kuburikidza-gomba rebhora iri perpendicular kune iyo yepakati migumo yemuviri wevhavha, uye pamusoro pebhora iri padhuze nepamusoro pekuisa chisimbiso chechigaro chevhavha kuti iite chisimbiso chekuvhara, kudzivirira kudonha kwepakati. Maererano nemhando dzakasiyana dzekuisa chisimbiso, mavharuvhu ebhora anogona kukamurwa kuva marudzi maviri: zvisimbiso zvakaoma uye zvisimbiso zvakapfava. Hard seal bhora mavharuvhu anoshandisa simbi (senge simbi isina simbi, hard alloy) sechinhu chekuisa chisimbiso, uye kuwana chisimbiso kuburikidza nemakanika kudzvanya kana kurodha pakati pesimbi. Iwo akakodzera kupisa kwepamusoro, kudzvanywa kwepamusoro, uye nharaunda dzinoparadza midhiya; Mavharuvhu akapfava akavharidzirwa anogadzirwa nealastic zvinhu zvakaita serabha uye polytetrafluoroethylene (PTFE), anoshandisa kudzvanywa kwepakati kukonzeresa deformation yechinhu chakapfava, nekudaro ichinamira pamusoro pebhora kuita chisimbiso. Vanoita zvakanaka pasi pekumanikidzwa kwakaderera uye mamiriro ekushisa kwekamuri.

Kuiswa chisimbiso kwebhora mavharuvhuinokanganiswa nezvinhu zvakawanda. Kuomarara, kupfeka kuramba, uye corrosion kuramba kwezvinhu zvekuisa chisimbiso zvakanangana nehupenyu hwekuisa chisimbiso. Semuenzaniso, kuoma kwepamusoro kwesimbi yekuisa chisimbiso nzvimbo inoda kuvandudzwa kuburikidza nemaitiro akadai sekupfapfaidza alloys yakaoma kana laser cladding; Mukutaura kwekugadzirisa kurongeka, zvigadziro zvakadai se sphere roundness uye chisimbiso chepamusoro chepamusoro chinoda kudzorwa zvakasimba, uye chisimbiso chepamusoro chepamusoro Ra kukosha kunowanzodiwa kuva ≤ 0.8 μ m; Hunhu hwegungano hwakakosha zvakaenzana, kutonga kwakashata kwesimba rekutanga kunogona kutungamira mukupfeka zvakanyanya kana kubuda kwenzvimbo yekuisa chisimbiso. Pamusoro pezvo, hunhu hwepakati (senge corrosiveness, tembiricha, kudzvanywa) uye mamiriro ekushanda (akadai sekuvhura uye kuvhara kumhanya) anogona zvakare kuve nemhedzisiro yakakosha pakuvharisa chisimbiso.

Kuti uchengetedze kushanda kwechisimbiso chevhavha yebhora, zvinodikanwa kugara uchitarisa kupfeka kwechisimbiso chepamusoro, tsvina yakachena panguva yakakodzera kudzivirira kukwenya, uye kuisa zvidimbu zvinofamba zvakadai sevhavha yevhavha. Kusarudza akakodzera chisimbiso zvimiro uye zvinhu zvemamiriro akasiyana ekushanda, sekushandisa simbi yakaoma chisimbiso bhora mavharuvhu nokuda kwepamusoro-tembiricha nharaunda uye fluorine kana cheramic coating chisimbiso nzvimbo nokuda ngura vezvenhau, anogona zvinobudirira kuwedzera basa upenyu mavharuvhu uye nechokwadi chisimbiso kuvimbika.
