Taw qhia dej huv
Nres kua dej yog kua nruab nrab uas xa mus rau hauv lub tsheb nres hydraulic thiab siv cov tsheb uas siv hydraulic nres tshuab. Nres fluid, tseem hu ua cov roj hauv paus lossis roj, nws lub npe ntawm lub npe yog Fruid Fluid, uas yog ib qho tseem ceeb ntawm cov nres nres nres. Hauv qhov system nres, nws siv los ua qhov nruab nrab rau quab yuam kis, vim tias cov kua no tsis tuaj yeem yuav tsum tau compressed, yog li qhov siab ntawm cov twj tso tawm hauv lub ntsiab tso tawm yuav raug xa mus ncaj qha mus rau lub ntsuas qis los ntawm lub ntsuas dej
Muaj peb hom roj kua dej.
1. Cov khoom siv roj chiv ntawm cov roj hmab: Nws yog npaj los ntawm muab cov roj ua kom zoo zoo nkauj 45% -55% thiab qis dej cawv (ethanol los sis butanol) 55% -45%, thiab muab cov kua ntshiab los yog lub tsho uas tsis muaj xim tsis pom los ntawm cov nag . Qhov nov yog, cawv hom kab mob ua kua. Cov roj carbon monoxide plus ethanol yog cawv hom No. 1, castor oil plus butanol yog cawv hom No. 3. Cov khoom siv cawv hom kua dej yog qhov yooj yim kom tau yooj yim, cov txheej txheem synthesis yooj yim, thiab cov khoom muaj lubric lub zog zoo; Tshem tsis tshua kub, tsis ruaj tsis khov ntawm qis dua. Cawv hom 1 muaj ethanol vapor saum toj 45 ° C, ua rau cov roj ua haujlwm; castor roj precipitates li cov dawb gel gel ntawm -25 ° C, thiab nce nrog ntsuas kub, thaiv qhov system nres Cov nres nres hnyav heev. Hauv qhov dej cawv hom 3 khob sim, lub tsaam thawj xim muaj xim me ntsis me ntsis, butanol ib nyuag dissolves cov hluav taws xob ntawm cov roj hmab, thiab dawb precipitates kuj yog precipitated ntawm -28 ° C. Cov ntawv nyeem qhia txog qhov sib ntxiv ntawm glycerol, tiam sis tseem muaj cov phom sij thiab stratification ntawm tsawg kub. Nyob rau hauv lub txias winters thiab kub summers,
Thib ob, hom hluavtaws: nrog ether, haus dej cawv, ester thiab lwm yam khoom ntxiv rau lubrication, anti-oxidation, anti-xeb, anti-roj hmab o thiab lwm yam khoom ntxiv.
3. Mineral roj hom: Nws yog tsim los ntawm kev ntxiv ib tus neeg saib xyuas cov thickening thiab lwm yam khoom ntxiv rau cov roj refined roj diesel roj feem.
