Imiterere ya Varnish mumavuta yo gusiga hamwe na hydraulic sisitemu imaze imyaka myinshi mubikorwa byinganda zamashanyarazi.Amateka, imiterere ya varish yitiriwe imizi imwe.Kurugero, hari # 2 ifite umurongo wamazi wa turbine ya gaz yakoraga imbere mumashanyarazi, ibyo bigatuma amavuta yangirika hamwe na varish.
Varnish irashobora kuba umutuku wijimye kugeza umukara muburyo bugaragara, bitewe nuburyo bwateje molekile yamavuta kumeneka no kwisiga.Ubushakashatsi buherutse gukorwa bwerekanye ko gusiga amavuta mubisanzwe ari ibisubizo byuruhererekane rwibyabaye.Kugirango utangire urunigi rwibintu, molekile zamavuta zigomba gucika.Inzira zimena molekile zamavuta ziri muribyiciro rusange: imiti, ubukanishi, nubushyuhe.
Imiti: Imyitwarire myinshi yimiti ibaho uko amavuta asaza.Oxidisation yamavuta iganisha kuri benshiibicuruzwa byangirika, harimo acide hamwe nuduce duto duto.Gushyushya no kuba hari ibice byicyuma nkicyuma cyangwa umuringa byihutisha inzira.Byongeye kandi, amavuta ahumeka cyane arashobora kwibasirwa cyane na okiside.Menya neza ko amavuta ahuza mbere yo kuyongeramo cyangwa kuyavanga, nkuko inyongeramusaruro zitandukanye zishobora kubyitwaramo nabi, bikongera gutesha agaciroamavuta.
Umukanishi: "Gukata" bibaho mugihe molekile zamavuta zashwanyagujwe iyo zinyuze hagati yimiterere yimashini.
Ubushyuhe: Iyo umwuka mwinshi winjiye mumavuta, kunanirwa gukabije kwamavuta bishobora kubaho bitewe nibihe bizwi nka Pressure-Induced Dieseling (PID) cyangwa Pressureinduced Thermal Degradation (PTG).Ibi bintu bishobozwa mubice byumuvuduko mwinshi muri sisitemu ya hydraulic.Imyuka iterwa na Dieseling, izwi kandi nka micro-dizel, ibaho mugihe umwuka mubi waguye munsi yumuvuduko mwinshi.Ibi bitanga ubushyuhe bwaho burenze 1000 deg F (538 deg C), ari nabwo butera kwangirika kwubushyuhe na okiside.
