Chinhu chinonyanya kukosha kusarudza sei amechanical sealmabasa anoenderana nezviso zvinotenderera uye zvakamira zvisimbiso.Chisimbiso chisos akarembera zvekuti hazviite kuti mvura kana gasi riyerere nemaari.Izvi zvinobvumira kuti shaft itenderere, nepo chisimbiso chiri kuchengetedzwa nemichina.Chii chinotarisa huwandu hwenguva iyo chisimbiso chichagara kusarudza iyo chaiyo seal material musanganiswa wekushandisa.Zviso zvakaomarara zviso zveabrasive service, Carbon Vs.Ceramic yemvura yakapfava (kana anti-freeze munyaya yemotokari yekushandisa).Carbon Vs.Silicon Carbide yezvishandiso zvakawanda kuderedza mashandisiro esimba uye kupa hupenyu hwakareba.Kune zvakakosha zvisimbiso zvakapetwa kaviri mechanical seals zvinowanzokurudzirwa.
Imwe neimwe nzira yekuvuza mukati memuchina chisimbiso yakavharwa nekushandiswa kwegasket, o-mhete, wedge (Rubber, PTFE kana Flexible Graphite).Chimwe chinhu chakakosha che mechanical pombi chisimbiso ndechekuchengetedza chisimbiso.Zvitubu (kamwe kana akawanda), mabhero esimbi kana angominyirirwa elastomers anoshandiswa kupa simba rinodiwa kuti urambe uchidzvanya zviso zvechisimbiso pamwechete.Mutoro unogashirwa nezviso zvechisimbiso unogadzirwa mukugadzirwa kwechisimbiso.Kusarudzwa kwechii chakanakisisa kunoenderana nekupisa, uye hunhu hwechiri kuvharwa (viscosity, abrasiveness, uremu (is slurry?)).
Mechanical zvisimbiso zvakagadzirirwa mapombi mazhinji, musanganiswa uye agitator maapplication mukugadzirisa.Muzviitiko zvakawanda madhizaini akaratidzirwa kuve mahosi ekushanda mumakore ekushandiswa.Mune zvimwe zvisimbiso zvinofanirwa kugadzirwa kuti zvigadzirise zvido zveindasitiri.Iyo yakakosha inotenderedza kumeso mechanical seal dhizaini inochinjika kuti ishumire yakawanda yekuisa chisimbiso maapplication anosanganisira compressors.Yakajairwa mechanicha zvisimbiso zvinogona kuenderana zvakanyanya zvinodiwa kune tembiricha ye500 madhigirii F uye shaft kumhanya kusvika 3600 RPM.Kusarudzwa kwechipiri chisimbiso rudzi kunowanzo gadzirisa tembiricha uye kugona kwemakemikari kwechisimbiso.Iko kusanganiswa kwezvinhu zvinoshandiswa muzviso zvinotenderera uye zvakamira zvinotsanangura abrasive resistance, uye chemical resistance.Seal face misanganiswa inozotarisawo huwandu hwesimba rinoshandiswa nepombi, musanganiswa, agitator kana compressor.Zviso zvechisimbiso zvinogona kuenzana kuti zvibvumire kuvharirwa kwepamusoro.Zvisimbiso zvine mwero zvinogona kuvhara kudzvanya pamusoro pe200 psi, kana kushandiswa mumatanho akawanda kune akanyanya kudzvanywa kana kunyanya kuomarara masevhisi emvura.OEM michina zvisimbisoinogona kupihwa kuti isangane neinodiwa zvakanyanya mumaindasitiri ekushandisa uchifunga kudzvanywa, tembiricha, kumhanya kana mvura.
