Ndezvipi zvakanakira tembiricha yemagineti pombi? ?

  Iyo yepamusoro-tembiricha yemagineti pombi imhando yekusabatika torque transmission kuburikidza nemagineti drive (magnetic coupling), kuitira kuti iyo static chisimbiso chinotsiva chisimbiso chine simba, kuitira kuti pombi isaburitse zvachose. Sezvo pombi shaft uye yemukati magineti rotor yakavharwa zvizere nemuviri wepombi uye sleeve yekuzviparadzanisa, dambudziko rekuvuza rinogadziriswa zvachose, uye njodzi yekuchengetedza yekupisa, inoputika, ine muchetura uye inokuvadza midhiya inodonha kuburikidza nepombi chisimbiso mukunatsa uye kemikari. indasitiri inobviswa.

Kuumbwa kwepombi

Iyo yakanyanya tembiricha yemagineti pombi ine zvikamu zvitatu: self-priming pombi, magineti drive uye mota. Chinhu chakakosha, iyo magineti drive, ine yekunze magineti rotor, yemukati magineti rotor uye isiri-magnetic yekuzviparadzanisa sleeve.

1. Magineti echigarire:
Magineti echigarire akagadzirwa nezvinhu ane yakakura yekushanda tembiricha renji (-45-400 ° C), yakakwirira yekumanikidza simba, yakanaka anisotropy munzira yegineti, uye hapana demagnetization ichaitika kana danda rimwechete riri pedyo nemumwe. Iyo imhando yeYakanaka kwazvo sosi yemagineti.

2. Sleeve yekuzviparadzanisa nevamwe:
Kana simbi spacer ichishandiswa, spacer iri mu sinusoidal alternating magnetic field, uye eddy current inonyandurwa pane chikamu perpendicular kugwara remagineti simba line uye inoshandurwa kuita kupisa.

3. Kudzora kwekutonhodza lubricant kuyerera
Kana pombi yemagineti yakakwira-tembiricha iri kushanda, mvura shoma shoma inofanira kushandiswa kukweshesa nekutonhodza nzvimbo yeringi pakati pemukati remagineti rotor uye sleeve yekuzviparadzanisa uye peya yekukwenya kweanotsvedza. Kuyerera kwechinotonhorera kunowanzo 2% -3% yedhizaini yekuyerera kwepombi, uye nzvimbo yemhete yepakati pakati pemukati magineti rotor uye sleeve yekuzviparadzanisa inoburitsa kupisa kwakanyanya nekuda kweeddy currents. Kana iyo inotonhorera yekuzora mvura isingakwani kana gomba rekutsvaira risina kutsvedzerera kana kuvharika, tembiricha yepakati inenge yakakwira kupfuura tembiricha yekushanda yemagineti isingaperi, kuitira kuti iyo yemukati magineti rotor zvishoma nezvishoma irasikirwe nemagnetism uye iyo magineti drive ichaita. kukundikana. Kana iyo yepakati iri mvura kana mvura-based fluid, kutonhora kunokwira munzvimbo ye annulus kunogona kuchengetedzwa pa 3-5 ° C; kana yepakati iri hydrocarbon kana mafuta, tembiricha inokwira munzvimbo ye annulus inogona kuchengetedzwa pa5-8 ° C.

4. Plain kubereka
Zvishandiso zvemagineti pombi inotsvedza mabearings zvinosanganisira impregnated graphite, yakazadzwa PTFE, engineering ceramics, etc. Nekuti engineering ceramics ine yakanaka kupisa kupisa, corrosion resistance, uye friction resistance, magineti mabearings anotsvedza anowanzo gadzirwa neinjiniya ceramics.
Sezvo mainjiniya ceramics ari brittle uye ane diki yekuwedzera coefficient, iyo inotakura clearance haifanirwe kunge iri diki zvakanyanya kudzivirira shaft-inobata tsaona. gadzira mabearings maererano nema media akasiyana uye mamiriro ekushanda.
