Mazwi okuti 'flushing' uye 'dzima' often seem to be confused or misused when discussing seal support schemes for >slurry pombi. Sezvo pfungwa dzemechanical seal cartridge uye yakazadzwa seal cartridge zvakasiyana zvishoma, ini ndichazvikurukura zvakaparadzana uye nekuchinjana.

Mechanical Seals

Iyo yakakosha mechanical seal flushing chirongwa chiri nyore kwazvo. Zvinoda kuti mvura yakachena / yakachena (kazhinji mvura) inounzwa munzvimbo pakati pechisimbiso chaicho uye impeller side outlet restriction. Iyo inoyerera mvura inounzwa pakumanikidzwa kwakakwira kupfuura iyo yekupomba, nekudaro kuve nechokwadi chekubuda kwakanaka / kuputika kwechisimbiso chemuchina uye nzvimbo yekushanda yakachena.
Flushing inotsanangurwa se "mvura inounzwa mugomba rechisimbiso padivi remvura, padyo nechiso chechisimbiso, uye inowanzo shandiswa kutonhorera nekuzora kumeso kwechisimbiso.

When flushing is required, the >slurry pombi mutengesi inokurudzira iyo API Option 32 yakavharwa pombi kurongeka sezvo ichinyanya kukodzera masevhisi ane solids kana zvinosvibisa zvinogona kukuvadza zviso zvechisimbiso kana ikatenderedzwazve mumhepo inoyerera.
Mvura yakachena yakachena inopihwa kubva kune yekunze sosi inowanzo shandiswa iyo inounzwa kune iyo huru yekuisa chisimbiso padivi remvura rekuisa chisimbiso. Nekushandisa yakavharwa gap huro bushing, iyo stuffing bhokisi inogona kudzoserwa-kumanikidzwa kune yakakwira kudzvanywa, kuve nechokwadi chekuti mvura inoyerera haivheneke pachiso chechisimbiso.

Chirongwa chekudzima, sezita rinoratidza, chakagadzirirwa kudzima kana kutonhodza chisimbiso. Inowanzo shandiswa kana nguva pfupi yekuoma kwekumhanya ichitarisirwa. Sezvinoratidzwa pazasi, mvura inounzwa munzvimbo iri pakati peshure kwezviso zvechisimbiso uye yekubuda kwakaringana kudivi rekutyaira kwepombi.
Inowanzoshandiswa kana nguva shomanana yekuoma yakaoma inotarisirwa. Fluid inounzwa munzvimbo iri pakati pekuseri kwechisimbiso kumeso uye inobatirira-yakakodzera yekubuda padivi rekutyaira repombi inotsvedza.

Kudzima kunotsanangurwa se "kupinzwa kwemvura isina kwayakarerekera (inowanzo mvura kana mupfu) mumhepo yepasi pechisimbiso kudzivirira kuumbwa kwezvakaoma zvinogona kukanganisa kufamba kana kushandiswa kune zvimwe zvinangwa.
Zvimwe zvinodzima zvisimbiso zvakarongwa kuti zvitsive chinovharira chinobatirira chisimbiso nechisimbiso chechipiri uye chepamusoro chinogona kuiswa pombi kuti chibate mvura yekudzima yakashandiswa nekuibvisa kubva pagungano rinotenderera. Zvisinei musimboti wacho wakafanana, tinoedza kutonhodza chisimbiso pane kuchiputisa neimwe nzira.

Yambiro: Chikanganiso chakajairika ndechekuwedzera-kumanikidza bhokisi uye kukuvadza inodhura mechanical chisimbiso.

Kurongedza bhokisi seal

The main objective of all flush water programmes is to prevent contamination of the seals by pumped water.The flush water programme for boxes is therefore very similar to the flush water programme for mechanically sealed boxes. However there are still some obvious mechanical differences.  The most notable difference is the addition of a seal (packing) between the inlet and outlet limits. This minimises the amount of flushing fluid consumed.

Kubva pane yekushanda yekuona bhokisi rekuisa rakasiyana sezvo richida kumwe kuvuza kuti ive nechokwadi chekuzora uye kudzivirira kupisa kuvaka. Iyo mechanical seal bhokisi inofanira kunge isina kubuda.
Mutemo wechigunwe chekuisa kudzvanywa kwemvura wakafanana kana uchishandisa bhokisi repakiti, kungave kutsvaira. Madhaka pombi yekuvhara-kuvharira kumanikidza kuwedzera gumi muzana kana kuwedzera makumi maviri psi, chero yakakura. Zvisinei, chiyero chekuyerera chinogadziriswa zvakasiyana.

Neyakajairwa flush hurongwa, kuyerera kunowanzo gadziridzwa nekumanikidza kurongedza kusvika madonhwe mashoma emvura achionekwa achidonha kubva kune zvisimbiso padivi rekutyaira. Muchirongwa chekudzima chiyero chekuyerera chinogadziriswa nekugadzirisa vheji yekupinza, nepo vharafu inoshandiswa padivi rekubuda kuti ichengetedze yakaringana seal tank pressure. Kana mvura yekubuda kubva mubhokisi rechisimbiso ichipisa zvakanyanya, chiyero chekuyerera chinowedzerwa kudzamara mvura yekubuda ichitonhorera, ichiri kuchengetedza iyo chaiyo seal box pressure.

I hope this short blog has helped to clear up some of the confusion about the seal flush programme. Please always refer to the pump manual for specific details. If there are still questions, welcome to >taura nesu nhasi.
