Ukwakhiwa kwe-varnish ku-lubricating oil kanye nezinhlelo ze-hydraulic sekuyiminyaka eminingi embonini yokutshala amandla.Ngokomlando, ukwakheka kwe-varnish kuye kwathiwa kudalwe imbangela eyodwa.Isibonelo, bekunomugqa wokudonsa ongu-#2 we-turbine yegesi owawuthinta ingaphakathi le-exhaust strut, okubangele ukuwohloka kokushisa kokwakheka kukawoyela nevanishi.
I-varnish ingaba nsundu ngokubomvu kuya emnyama ngokubukeka, kuye ngokuthi indlela eyabangela ukuba i-molecule yamafutha iphuke futhi i-varnish yakheke.Ucwaningo lwakamuva luye lwembula ukuthi ukuvenisha kwamafutha ngokuvamile kuwumphumela wochungechunge oluyinkimbinkimbi lwezenzakalo.Ukuqala lolu chungechunge lwemicimbi, ama-molecule kawoyela kufanele aphulwe.Izinqubo eziphula ama-molecule kawoyela ziwela kulezi zigaba ezijwayelekile: amakhemikhali, ama-mechanical, kanye ne-thermal.
Amakhemikhali: Ukusabela kwamakhemikhali okuningi kwenzeka njengoba iminyaka kawoyela.I-oxidation yamafutha iholela kokuningiimikhiqizo yokubola, okuhlanganisa ama-asidi nezinhlayiya ezingancibiliki.Ukushisa nokuba khona kwezinhlayiya zensimbi njengensimbi noma ithusi kusheshisa inqubo.Ukwengeza, amafutha ane-aerated kakhulu angangenwa kalula yi-oxidation.Qinisekisa ukuthi uwoyela uyahambisana ngaphambi kokuwangeza noma ukuwaxuba, njengoba izithasiselo ezihlukene zikawoyela zingase zisabele kabi, zidilize isithunzi.amafutha.
Okokusebenza: "Ukugunda" kwenzeka lapho ama-molecule kawoyela ehlukaniswa njengoba edlula phakathi kwezindawo ezihambayo.
Okushisayo: Uma amabhamuza omoya efakwa emafutheni, ukwehluleka okukhulu kwamafutha kungase kwenzeke ngenxa yezimo ezaziwa ngokuthi yi-Pressure-Induced Dieseling (PID) noma i-Pressureinduced Thermal Degradation (PTG).Lezi zenzakalo zinikwe amandla ezindaweni ezinengcindezi ephezulu ngaphakathi kwezinhlelo ze-hydraulic.I-Pressure Induced Dieseling, eyaziwa nangokuthi i-micro-diesel, kwenzeka lapho amabhamuza omoya ewa ngaphansi kwengcindezi ephezulu.Lokhu kukhiqiza amazinga okushisa asendaweni angaphezu kuka-1000 deg F (538 deg C), okubuye kuholele ekulimazeni okushisayo kanye ne-oxidation.
Izindlela zokuthola i-Varnish
Uhlelo lokuqapha isimo sikawoyela kufanele lube yingxenye yokunakekelwa okuvamile okuhlanganisa inhlanganisela yokuhlolwa nokuhlolwa kokuhlaziya uwoyela.Ukuhlola kuhlanganisa ukubuka izibuko zokuvanisha nokungcolisa, ukuhlola izihlungi ezisetshenzisiwe ze-varnish ene-end-cap ne-sludge, ukuhlolwa kwe-servo inlet port kanye nezihlungi ze-lastchance, nokuhlolwa ngezikhathi ezithile kwe-sediment engaphansi kwethangi.
Nakuba ingekho indlela eqondile yokulinganisa (ukulinganisa) ukwakheka kwevarnish ezindaweni eziphakeme zevalvu ye-servo, ukusetshenziswa okusebenzayo kokuhlolwa kokuhlola kungase kunikeze isixwayiso sangaphambi kwesikhathi esisebenzayo.Isivivinyo se-patch colorimetric singasetshenziselwa ukuthambekela amandla okuvanisha kawoyela.Izinombolo eziphansi zibonisa ingozi ephansi yokwakheka kwe-varnish.Ukuze uthole ireferensi evamile, ukukala okungaba khona kwevarnish phakathi kuka-0 no-40 kuzobhekwa njengokwamukelekayo.Ububanzi obungu-41-60 bungaba yisimo esingabikwa, esibonisa isidingo soku
ukuqapha amafutha njalo.Ukufundwa okungaphezulu kuka-60 kuthathwa njengokusebenza futhi kufanele kuqalise uhlelo lokusebenza lokulungisa isimo ngokushesha.Ukuqapha izinhlayiya ze-sub micron emafutheni kanye nemiphumela yokuhlolwa kwe-patch colorimetric kungasiza ekunqumeni ukusebenza kahle kokukhishwa kwezinhlayiya zokuvanisha.Ukuhlolwa okusetshenziselwa ukukala izinhlayiya ezincane ze-micron yi-ASTM F 312-97 (Indlela Yokuhlola Ejwayelekile Yokulinganisa Usayizi We-Microscopical kanye Nezinhlayiya zokubala ezivela ku-Aerospace Fluids Kuzihlungi Ze-Membrane) Kunconywa ukuthi zombili lezi zivivinyo zisetshenziselwe ukuqapha ukusebenza kwemishini yokumisa uwoyela. .
Ukunciphisa Nokuvimbela
Amakhasimende asebenzisayo njengamanjei-electrostaticisihlanzi samafutha, nomaI-balanced charge oil purifierfuthiIyunithi yokususa i-varnish, baye babika imiphumela emihle kakhulu ekunciphiseni amandla e-varnish amafutha abo.Le miphumela ibonisa ukuthi uhambo olubangelwa ama-valve e-servo anamathelayo luncishiswe kakhulu noma lwaqedwa.Ngokungafani nezihlungi ezivamile, lobu buchwepheshe budala ukushajwa kukagesi ezinhlayiyeni ezimisiwe (ama-oxides, izinhlawulo zekhabhoni, njll.) ezisiza ukukhishwa kwazo kuwoyela, ngokuhlungwa noma nje ngemvula ye-electrostatic kudivayisi yokuqoqa.Kufanele kuqashelwe ukuthi inkambiso yokuqala eyehlayo ibonakala ngesikhathi sokuhlanza okulandelwa futhi
ukuthambekela okukhuphukayo njengoba ivashi ebichithiwe phezu kwesistimu iphinde ingene emafutheni.Ngokuhamba kwesikhathi, lokhu kuqhakaza kwevarnish kuzokwehla kubuyele emazingeni afiselekayo njengoba iyunithi yokuphinda isebenze, okushiya izindawo ezingaphezulu zesistimu kawoyela namafutha enjini yomoya kuhlanzekile.Lobu buchwepheshe bungasetshenziswa ukunciphisa inkinga yamanje yokuvanisha noma ukuvimbela ukwenzekakwayo.
