Tarisa kuti pane kuvuza: Mushure mekusanganazve, tarisa kune chero kuvuza kwakatenderedza nzvimbo yechisimbiso kuti uve nechokwadi chekuiswa kwayo.

Mapombi Mechanical Seals anogara kwenguva yakareba sei?
Hupenyu hwepombi mechini zvisimbiso chinhu chakakosha chekuchengetedza uye kushanda zvakanaka mumaindasitiri akasiyana siyana. Kazhinji, pasi pemamiriro ezvinhu akanaka, chisimbiso chakachengetwa zvakanaka chinogona kugara chero kubva kune 1 kusvika kumakore matatu zvisati zvada kuchinjwa kana kugadziriswa. Nekudaro, zvakakosha kuziva kuti hupenyu chaihwo hwesevhisi hunogona kusiyana zvakanyanya zvichienderana nezvikonzero zvakati.

Zvinhu zvakakosha zvinopesvedzera kusimba kwepombi mechanicha zvisimbiso zvinosanganisira chaiyo indasitiri yekushandisa, mamiriro ekushanda senge tembiricha uye kudzvanywa, rudzi rwemvura iri kupomba, uye kuvapo kwezvinhu zvinokuvadza kana zvinoparadza mukati memvura. Uyezve, kuumbwa kwezvinhu zvechisimbiso uye kugadzirwa kwayo (kuenzanisa vs. unbalanced, cartridge vs. bellow, etc.) inotamba mabasa anokosha pakusarudza hupenyu hwayo hurefu.

Kugadzirisa nguva nenguva uye kuiswa kwakakodzera kwakakoshawo pakuwedzera hupenyu hwezvisimbiso izvi. Kuve nechokwadi chekuti zviso zvechisimbiso zvinoramba zvakachena uye zvisina kurongeka, kutarisa zviratidzo zvekusakara uye kubvaruka, uye kuomerera kune zvakatemwa zvemugadziri wekushanda zvinogona kurebesa nguva yavo inoshanda.

Hupenyu hweMechanical Chisimbiso Hunogona Kuwedzerwa Sei?
Kuwedzera hupenyu hwechisimbiso chemuchina mumapombi emvura kunosanganisira kunyatsogadzirisa, kuisirwa kwakaringana, uye kushanda mukati meiyo yakatarwa paramita.

Kusarudzwa kwakakodzera kunoenderana nezvinodiwa zvechikumbiro kunovimbisa kuenderana nemamiriro ekushanda. Kugara uchiongorora uye kugadzirisa kunoderedza kupfeka uye kudzivirira kukundikana zvisati zvave zvakakosha. Kuve nechokwadi chemvura yakachena kwakakosha sezvo zvinosvibisa zvinogona kukurumidza kupfeka. Kuisa zvidzoreso kwezvakatipoteredza, senge seal flush zvirongwa, kunyatso gadzirisa kupisa uye kubvisa zvimedu zvinogona kukuvadza zviso zvechisimbiso.

Kuenzanisa maparamendi ekushanda kuti udzivise kudzvinyirira kwakanyanya kana tembiricha inodarika zvakatemwa nechisimbiso kwakakosha pakurarama kwenguva refu. Kushandisa lubrication uye kutonhora masisitimu pazvinenge zvichidikanwa kunobatsira kuchengetedza mamiriro akakwana ekushanda chisimbiso. Kudzivisa yakaoma kumhanya mamiriro anochengetedza chisimbiso kutendeseka nekufamba kwenguva.

Kudzidzisa vashandisi pane zvakanakisa maitiro ekutanga-up uye kuvharika maitiro kunodzivirira kushushikana kusingakoshi pamagetsi seals. Kutevedzera zvirongwa zvekugadzirisa nguva nenguva kuti uongorore zvinhu zvakaita sezvitubu, mabhero, uye makora ekukiya zviratidzo zvekupfeka kana kukuvadzwa kunoita basa rakakosha mukuwedzera hupenyu hwesevhisi.

Nekutarisa pakusarudzwa kwakakodzera, kunyatsoisa, matanho ekudzivirira kurwisa ingress yakasvibiswa, uye kuomerera kune nhungamiro yekushanda, hupenyu hwepombi yemvura mechanical seals inogona kuvandudzwa zvakanyanya. Iyi nzira haingochengetedzi chete kuvimbika kwepombi masisitimu asiwo inogonesa kugona kwese nekudzikisa nguva yekudzikira uye mari yekugadzirisa.

Mukupedzisa
Mukupfupisa, pombi yemvura mechanical seal chinhu chakakosha chakagadzirirwa kudzivirira kudonha uye kuve nechokwadi chekushanda kwakanaka kwemapombi ecentrifugal nekuchengetedza chipingamupinyi pakati pemvura iri kupomba uye nharaunda yekunze.
