“Ingabe unazo iziphakamiso ngezinkinga zokuncibilika kwemikhiqizo ye-oxidation kuwoyela we-turbine emazingeni okushisa aphansi?Muva nje, amakhasimende ami abe nenkinga ngokuncibilika kwemikhiqizo ene-oxidized ku-turbine namafutha we-hydraulic.Emazingeni okushisa okusebenza (60-80 degrees С), ayancibilika, kodwa lapho amiswa (okungukuthi, emazingeni okushisa angaphansi kuka-25 degrees C), awancibiliki futhi aqale ukubeka endaweni yokusebenza.Lokhu kuyinkinga ngamaphampu e-hydraulic piston, futhi akunandaba ukuthi hlobo luni lwe-turbine (igesi/umusi/njll. noma umkhiqizi) noma amahora okusebenza.”
Ngokusekelwe kumazwana akho, kungenzeka ukuthi ubhekene nokwakheka kwe-varnish, okuyinkinga evamile kumasistimu okushisa aphezulu kanye nengcindezi ephezulu njengama-steam turbines noma ama-hydraulic systems asebenza kahle kakhulu.
I-varnish iwukunqwabelana kwe-oxidation kawoyela kanye nezinhlanganisela zokuwohloka endaweni yomshini noma izingxenye.Kungaba umphumela wezimbangela ezimbalwa ezingaba yizimpande, okuhlanganisa izinga lokushisa eliphezulu, ukukhishwa kwe-electrostatic, ukuwohloka kwamafutha kanye ne-microdieselling.I-varnish ingaveza izinkinga eziningi ezihlobene nokusebenza komshini, njengokugxilwa kwe-valve, ukuvinjelwa kokugeleza kwamafutha, izihlungi ezivaliwe, njll.
I-varnish iqala njengokungcola okuncibilikile.Lapho lokhu kungcola kunqwabelana futhi kufinyelele endaweni yokugcwala, kuthuthela endaweni engaphezulu yesistimu yokugcoba.Uma lawa ma-deposit ehlala endaweni engaphezulu, ayelapha (aqina) ngokuhamba kwesikhathi, okubangela ukwehluleka kwesistimu ye-lube kanye nezingxenye ezigcotshiwe.
Ukumelana ne-oxidation kanye ne-solubility yizici ezimbili ezibalulekile zokugcoba okufanele zicatshangelwe.Ukumelana ne-oxidation kubhekisela endleleni ama-molecule amelana ngayo nokusabela kwamakhemikhali nomoya-mpilo osemoyeni.I-oxidation yehlisa uwoyela futhi ingesinye sezizathu eziyinhloko zokuwushintsha.Uma kukhulu ukumelana ne-oxidation, impilo kawoyela iba yinde.
I-Solubility yisakhiwo esivumela okokugcoba ukuthi kubambe izinto ze-polar njenge-varnish ekumisweni ngaphandle kokulimala emshinini.Ukuncibilika kukawoyela kuyanda emazingeni okushisa aphezulu.Amafutha eqembu III nawo ane-solubility ephansi kunamafutha weQembu II kanye neqembu I.Kube nezimo eziningi zemishini ehlangabezana nediphozithi yokuvanisha ngenxa yokuncibilika kancane kwamafutha ngemva kokushintsha uwoyela weQembu I iye kuwoyela weQembu II noma III.
Uma ubhekene ne-varnish deposits, izenzo ezimbili zinconywa ukuyilawula.Okokuqala, thola izimbangela.Lokhu kuzodinga ucwaningo oluhlelekile lwezici ezingase zisekelwe ukuhlaziya uwoyela.Okulandelayo, susa i-varnish ekhona emshinini.Lokhu kungafezwa ngokungeza izithasiselo ze-solvent noma okokuhlanza emafutheni, usebenzisa umkhiqizo wokwenziwa one-solvency ephezulu yemvelo noma ukufaka izinhlelo zokususa i-varnish.Ezimweni ze-varnish eqinile, isisombululo sizoba ngomshini futhi singase sihilele ukushintsha izingxenye.
