Ukubunjwa kwe-varnish kwi-lubricating oil kunye ne-hydraulic systems ikhona iminyaka emininzi kwishishini leplanti yamandla.Ngokwembali, ukwenziwa kwevarnish kuye kwanxulunyaniswa nonobangela wengcambu eyodwa.Ngokomzekelo, kwakukho umgca we- # 2 othwele i-drain ye-turbine yegesi eyayichukumisa ngaphakathi kwi-exhaust strut, eyabangela ukuthotywa kwe-thermal ye-oyile kunye nokwakheka kwevanishi.
I-Varnish ingaba ngumbala obomvu obomvu ukuya kumnyama ngokubonakala, kuxhomekeke kwindlela eyenza ukuba i-molecule yeoli iphule kunye ne-varnish.Uphononongo lwakutsha nje lubonise ukuba ukuvanishwa kweoyile kudla ngokuba ngumphumo woluhlu oluntsonkothileyo lweziganeko.Ukuqala olu luhlu lweziganeko, iimolekyuli zeoyile kufuneka zaphulwe.Iindlela zokwaphula iimolekyuli zeoyile ziwela kwezi ndidi ziqhelekileyo: iikhemikhali, oomatshini kunye ne-thermal.
Ikhemikhali: Iindlela ezininzi zeekhemikhali zenzeka njengoko ixesha leoyile lihamba.I-oxidation yeoli ikhokelela kwizinto ezininziiimveliso zokubola, kubandakanywa ii-asidi kunye neenxalenye ezinganyibilikiyo.Ukushisa kunye nobukho bezinto zetsimbi ezifana nentsimbi okanye ubhedu zikhawulezisa inkqubo.Ukongeza, ii-oyile ezine-aerated kakhulu zichaphazeleka ngakumbi kwi-oxidation.Qinisekisa ukuba iioyile ziyahambelana phambi kokuba uzifake okanye uzixube, njengoko izongezo zeoyile ezahlukeneyo zinokusabela kakubi, ziphinde zithobe isidima.ioli.
Oomatshini: “Ukucheba” kwenzeka xa iimolekyuli zeoyile zikrazulwa phakathi njengoko zidlula phakathi kwemiphezulu eshukumayo yoomatshini.
I-Thermal: Xa amaqamza omoya efakwa kwi-oyile, ukungaphumeleli okukhulu kweoli kunokuthi kwenzeke ngenxa yeemeko ezaziwa ngokuba yi-Pressure-Induced Dieseling (PID) okanye i-Pressureinduced Thermal Degradation (PTG).Ezi ziganeko zinikwe amandla kwiindawo zoxinzelelo oluphezulu ngaphakathi kweenkqubo ze-hydraulic.I-Pressure Induced Diesling, ekwaziwa ngokuba yi-micro-diesel, kwenzeka xa amaqamza omoya ewa phantsi koxinzelelo oluphezulu.Oku kuvelisa amaqondo obushushu asekuhlaleni angaphezu kwe-1000 deg F (538 deg C), nto leyo ekhokelela ekuthotyweni kwe-thermal kunye ne-oxidation.
Iindlela zokufumana iVarnish
Inkqubo yokuhlola imeko ye-oyile kufuneka ibe yinxalenye yolondolozo oluqhelekileyo olubandakanya indibaniselwano yokuhlolwa kunye novavanyo lokuhlolwa kweoli.Ukuhlola kubandakanya ukujonga iiglasi zokujonga ivanishi kunye nokungcola, ukuphonononga izihluzi ezisetyenzisiweyo kwi-varnish yokuphela kwe-cap kunye ne-sludge, ukuhlolwa kwe-servo inlet port kunye nezihluzo zokugcina, kunye nokuhlolwa kwexesha le-tank sediment.
Ngelixa kungekho ndlela ethe ngqo yokulinganisa (ukulinganisa) ukubunjwa kwevanishi kumphezulu wevalve ye-servo, ukusetyenziswa okusebenzayo kovavanyo lokuhlola kunokubonelela ngesilumkiso esisebenzayo kwangethuba.Uvavanyo lwe-patch colorimetric lunokusetyenziswa ukwenza ivarnish enokubakho kwioyile.Amanani aphantsi abonisa umngcipheko ophantsi wokubunjwa kwe-varnish.Ngokubhekiselele ngokubanzi, ukulinganiswa okunokwenzeka kwevarnish phakathi kwe-0 kunye ne-40 kuya kuthathwa njengokwamkelekileyo.Uluhlu lwe-41-60 luya kuba yimeko echazweyo, ebonisa imfuneko yokuba
esweni ioli rhoqo.Ukufundwa okungaphezulu kwe-60 kuthathwa njengento enokwenziwa kwaye kufuneka kubangele isicwangciso somsebenzi ngokukhawuleza ukulungisa imeko.Ukubeka iliso kwiincinci ze-micron kwi-oyile kunye neziphumo zovavanyo lwe-patch colorimetric kunokunceda ekuqinisekiseni ukusebenza kakuhle kokususwa kwamasuntswana evarnish.Uvavanyo olusetyenziselwa ukulinganisa i-sub micron particles yi-ASTM F 312-97 (iNdlela yoVavanyo oluMiselweyo lweMicroscopical Sizing kunye nokubala kwaMacandelwana asuka kwi-Aerospace Fluids kwi-Membrane Filters) Kucetyiswa ukuba zombini ezi mvavanyo zisetyenziselwe ukubeka esweni ukusebenza kwezixhobo zokulungisa ioyile. .
Ukunciphisa kunye noThintelo
Abathengi abasebenzisa ngokui-electrostaticisicoci seoli, okanyeIxabiso elilinganayo lokucoca iolikwayeIyunithi yokususa i-varnish, baye babika iziphumo ezintle kakhulu ekunciphiseni amandla e-varnish yeoli yabo.Ezi ziphumo zibonisa ukuba iihambo ezibangelwa kukuncamathelisa iivalvu ze-servo ziye zancitshiswa kakhulu okanye zayekiswa.Ngokungafaniyo nezihluzo zoomatshini eziqhelekileyo, obu bugcisa bubangela ukuba kuhlawuliswe umbane kumasuntswana amisiweyo (iioksidi, izohlwayo zekhabhoni, njl.njl.) eziququzelela ukuhanjiswa kwazo ngaphandle kwe-oyile, ngokuhluzwa okanye ngokulula imvula ye-electrostatic kwisixhobo sokuqokelela.Kufuneka kuqatshelwe ukuba indlela yokuqala yokuhla iyenzeka ngexesha lokucoca kulandelwa kunye
indlela yokuya phezulu njengoko ivanishi ebithe yacandwa kumphezulu wenkqubo iphinda ifakwe kwi-oyile.Ngokuhamba kwexesha, le ntyatyambo ivanishi iya kuhla ibuyele kumanqanaba anqwenelekayo njengoko iyunithi yokubuyisela ihlala ikwinkonzo, ishiya umphezulu weoyile kunye neoyile ye-injini icocekile.Le teknoloji ingasetyenziselwa ukunciphisa umba we-varnishing yangoku okanye ukuthintela ukwenzekangayo.
