"Iwe une chero mazano ematambudziko nekunyungudika kwezvigadzirwa zveoxidation muoiri yeturbine pane tembiricha yakaderera?Munguva pfupi yapfuura, vatengi vangu vanga vaine dambudziko nekunyungudika kwezvigadzirwa zvine oxidized mu turbine uye hydraulic oiri.Pakushanda tembiricha (60-80 degrees С), inonyungudika, asi pakumisa (kureva, tembiricha iri pasi pe25 degrees C), inova isinganyungudika uye inotanga kuisa panzvimbo yekushanda.Iri idambudziko nemapombi e hydraulic piston, uye hazvina basa nemhando yeturbine (gasi/timu/etc. kana mugadziri) kana maawa ekushanda.”
Zvichienderana nezvaunotaura, unogona kunge uchibata nekuumbwa kwevarnish, rinova dambudziko rinogara richiitika mukupisa kwepamusoro uye kudzvanya-kumanikidza masisitimu senge ma turbines emhepo kana akakwira-performance hydraulic system.
Varnish ndiko kuunganidzwa kweoiri oxidation uye degradation makomisheni pamashini kana zvikamu.Inogona kuve mhedzisiro yezvizhinji zvinokonzeresa midzi, kusanganisira kupisa kwakanyanya, electrostatic discharges, lubricant degradation uye microdieselling.Varnish inogona kuburitsa akati wandei matambudziko ane chekuita nekushanda kwemuchina, senge valve stiction, lubricant flow restriction, clogged mafirita, nezvimwe.
Varnish inotanga seyakanyungudika tsvina.Kana tsvina iyi ikaungana uye ichisvika pakuzara, inotama ichienda kunzvimbo yekuzora mafuta.Kana dhipoziti idzi dzikaramba dziri panzvimbo, dzinorapa (kuomesa) nekufamba kwenguva, zvichikonzera kutadza kwelube system uye zvinhu zvakazorwa.
Oxidation kuramba uye kunyungudika zvinhu zviviri zvakakosha zvemafuta zvekufunga nezvazvo.Oxidation resistance (oxidation resistance) zvinoreva kuti mamorekuru anoramba sei kuita kwekemikari neokisijeni iri mumhepo.Oxidation inosvibisa oiri uye ndicho chimwe chezvikonzero zvikuru zvekuishandura.Iyo yakakura iyo oxidation kuramba, iyo yakareba hupenyu hweoiri.
Solubility inzvimbo inobvumira lubricant kubata zvinhu zvepolar senge varnish mukumisa pasina kukuvara kumushini.Kunyungudika kwemafuta kunowedzera pakupisa kwakanyanya.Boka III oiri zvakare ine yakaderera solubility pane Boka II uye Boka I oiri.Pakave nezviitiko zvakawanda zvemichina inosangana nevarnish deposits nekuda kwekuderera kunyungudika kwemafuta mushure mekuchinja kubva kuGroup I mafuta kuenda kuGroup II kana III mafuta.
Kana iwe wakatarisana nemadhipoziti evarnish, zviito zviviri zvinokurudzirwa kuti uzvidzore.Kutanga, ziva zvikonzero zvikuru.Izvi zvinoda kuongororwa kwakarongeka kwezvinhu zvinogona kutsigirwa nekuongorora kwemafuta.Zvadaro, bvisa varnish iripo mumushini.Izvi zvinogona kuwanikwa nekuwedzera solvent kana detergent additives kumafuta, uchishandisa chigadzirwa chekugadzira chine high natural solvency kana kuisa varnish yekubvisa masisitimu.Muzviitiko zvevarnish yakaoma, mhinduro ichava yemagetsi uye inogona kungosanganisira kushandura zvikamu.
