Cov lus no teev cov khoom ntsuas tseem ceeb rau kev tshuaj xyuas cov roj turbine zoo, muaj feem xyuam rau kev saib xyuas niaj hnub, kev saib xyuas kev saib xyuas, thiab kev kuaj pom cov roj tshiab.
| Cov khoom xeem (English) | Lub Hom Phiaj & Qhov Tseem Ceeb | Common Test Standard |
|---|---|---|
| Kinematic Viscosity (40℃/ 100 degree) | Txiav txim siab cov roj ntws ua haujlwm nyob rau hauv kev ua haujlwm kub; xyuas kom lubrication zaj duab xis lub zog thiab kev muaj peev xwm | GB / T 265, ASTM D445 |
| Viscosity Index | Reflects viscosity hloov pauv nrog kub; tus nqi siab dua txhais tau tias zoo dua viscosity stability | GB/T 1995, ASTM D2270 |
| Acid Number | Ntsuam xyuas oxidation℃ntawm turbine roj; nce acid naj npawb qhia cov roj aging thiab muaj peev xwm corrosion rau hlau qhov chaw | GB / T 264, ASTM D974, ASTM D974, ASTM D974 |
| Neutralization Number | Ntsuas tag nrho cov tshuaj acidic / alkaline hauv cov roj; coj lub voj voog hloov roj | GB / T 4945, ASTM D664 |
| Cov ntsiab lus dej | Cov dej ntau dhau ua rau emulsification, txo cov roj lubrication, thiab ua rau xeb ntawm cov khoom siv turbine. | GB / T 260, ASTM D95 |
| Flash Point (Qhib khob) | Ntsuas cov roj kev nyab xeeb kev ua haujlwm; tiv thaiv hluav taws kub nyob rau hauv siab - qhov chaw ua haujlwm kub | GB / T 3536, ASTM D92 |
| Ncuav Point | Txiav txim siab qhov qis -kub fluidity ntawm roj; ua kom muaj kev pib ib txwm nyob hauv thaj chaw txias | GB / T 510, ASTM D97 |
| Mechanical impurities | Tshawb xyuas cov khoom hauv cov roj; impurities tuaj yeem ua rau hnav ntawm bearings, gears, thiab lwm yam precision Cheebtsam | GB/T 511, ASTM D4870, ASTM D4870, ASTM D4870, ASTM D4870 |
| Oxidation stability | Ntsuas cov roj tsis kam rau oxidation ntawm qhov kub thiab txias; kwv yees lub neej kev pab cuam ntawm turbine roj | GB / T 12581, ASTM D943 |
| Txoj Cai Kev Xeem (Demulsibility) | Kuaj cov roj muaj peev xwm cais tawm dej; turbine roj yog nquag rau dej sib tov, yuav tsum tau zoo demulsibility | GB / T 7305, ASTM D1401 |
| Foaming Tendency thiab Stability | Tiv thaiv ua npuas ncauj ntau dhau los ntawm kev txo cov roj siab thiab cuam tshuam rau lubrication; ua npuas ncauj kuj tuaj yeem ua kom cov roj oxidation | GB / T 12579, ASTM D892 |
| Copper Sawb Corrosion (100 degree, 3h) | Ntsuas cov roj corrosiveness rau tooj liab alloy Cheebtsam (piv txwv li, ntsaws ruaj ruaj, kav dej) | GB / T 5096, ASTM D130 |
