Chimiro chepombi yemota iri nyore, inoumbwa neipeller, goko uye chisimbiso chemvura, impeller ndiyo yepakati zvikamu zvepombi, inowanzo gadzirwa nesimbi yakakandwa kana plastiki, impeller kazhinji ine 6 ~ 8 radial yakatwasuka blade kana yakabhenda blade.Iyo huru yekukuvadza fomu yepombi yemvura kukuvadzwa kweblade uye mvura seal leakage, inova ndiyo huru yekukuvadza kwepombi yeblade.

Mukutaura kwakapfava, pane kunyanya zvinotevera zvinhu zvinotungamira mukukuvadzwa kwepombi blades:

1. Iyo inotonhorera inobaiwa muchirongwa chekutonhodza haina kukodzera, kana kuti inotonhorera haitsiviwa kwenguva yakareba.Ikozvino injini inowanzo shandiswa antifreeze senge yekushanda svikiro yeinotonhodza system, antifreeze haingodziviri chando chete, zvakare ine kufashaira, ngura uye corrosion kudzivirira maitiro, ine corrosion inhibitor, defoaming agent, colorant, fungicide, buffering agent uye zvimwe zvinowedzera. zvinobudirira kudzivirira injini kuora kwesimbi substrate uye kuzvimba kwepombi.Kana antifreeze isingaparadzi, kana antifreeze yakashandiswa kwenguva yakareba, antifreeze additives mu antifreeze inopera, uye antifreeze inosvibisa pombi impeller kusvikira impeller yaita ngura zvachose.Iye zvino motokari dzakawanda dzinoda makore maviri kana makiromita 40 zviuru kutsiva antifreeze, kunyanya nokuda kwechikonzero ichi.

2. Iyo yekutonhodza system haishandisi antifreeze asi yakajairika mvura pachinzvimbo, iyo inomhanyisa kukuvara kwepombi.Sezvatinoziva, mvura yakananga kusangana nesimbi, ichatungamirira kune simbi ngura, kana isina kunatswa pombi mvura kana rwizi mvura, ngura chiitiko achava zvakakomba, uye kutungamirira ngura pombi blade, kukuvara.Pamusoro pezvo, kushandiswa kwemvura pachinzvimbo cheantifreeze kuchaburitsawo chiyero, dhipoziti mutangi remvura uye mugero weinjini, zvichikonzera kushata kwekupisa uye kunyange kupisa kwakanyanya kwejini.

3, kune mweya mukati mekutonhora system, cavitation corrosion phenomenon corrosion pombi blade.Inogona kuonekwa kubva pamusimboti wekushanda wepombi yemvura, pombi kana pombi ichishanda pane blade ishanduko yekumanikidza, kana mvura inotonhorera ine mabhubhu emhepo, mabhubhu achaona nzira yekumanikidza, kuwedzera, kana yakaputsika, uye mukugadzirisa kwekuwedzera kwekanguva yakaputsika ichabudisa kukanganisa kukuru, migumisiro pamucheka, Nokufamba kwenguva, pamusoro pechidzitiro chichabudisa nhamba yakawanda yegomba, iyo inoshamisa ye cavitation.

Cavitation kwenguva yakareba inotungamirira mukukuvadzwa kwepombi blade kusvikira yanyangarika.Mune yakavhurika inotonhorera system yakashandiswa munguva yakapfuura, cavitation phenomenon yakanyanya kuoma, kunyanya kukanganisa kwepombi blade kunokonzerwa necavitation;Motokari zvino dzinoshandisa maitiro akawanda akavharwa ekutonhora, saka mukana wemhepo inopinda muhurongwa inoderedzwa zvikuru, uye pane zvishoma cavitation.Asi kana injini kazhinji ipfupi kutonhora, mhepo ichapinda, uye inowedzera kuwedzera cavitation.Chishandiso chikuru chekuparadzanisa mweya mune yazvino mota yekutonhodza system ndiyo yekuwedzera tangi remvura.Kazhinji, chero bedzi paine inotonhorera mairi, mhepo haipindi muhurongwa.

Izvi ndizvo zvinhu zvikuru zvinotungamira mukukuvadzwa kwepombi yemota blade.Muchokwadi, kwete chete pombi yemotokari, mamwe mapombi emuchina anewo dambudziko rakafanana, iyo yekukuvadza nzira yepombi blade yakaoma kwazvo, inosanganisira ruzivo rwakadzama rwemvura mechanics, nesezvinogoneka kudzikamisa kukuvadzwa kwepombi blade, kurebesa hupenyu hwebasa hwepombi idambudziko repasi rose.Kune mota dzedu, isu tinofanirwa kuwedzera antifreeze inokodzera, usashandise pombi yemvura uye mvura yerwizi, usarega iyo inotonhorera nhanho yakadzikira, iyo inogona kunyatso kudzivirira kukanganisa kwepombi blade.
