      一、手捻法。将润滑油捻在大拇指与食指之间反复研磨,较好的润滑油手感到有润滑性、磨屑少、无摩擦,若感到手指之间的砂粒之类较大摩擦感,则表明润滑油内杂质多,不能再用,应换新润滑油。

      Hand twist method. Be twist lubricating oil between the thumb and forefinger grinding, good lubricating oil hand feel less lubricity, wear debris, no friction, if feel fingers between the larger friction feeling such as sand, suggests that the impurity, lubricating oil can no longer use, a new lubricating oil should be replaced.

                             

      二、光照法。在天气晴朗的日子,用螺丝刀将润滑油撩起,与水平面成45度角。对照阳光,观察油滴情况,在光照下,可清晰地看到润滑油中无磨屑为良好,可继续作用,若磨屑过多,应换润滑油。

            Illumination method. On a clear day, use a screwdriver to lubricating oil lifted, and horizontal Angle of 45 degrees. Contrast sunshine, observe the oil situation, under the light, can see clearly without wear debris in lubricating oil is good, can continue to function, if excessive wear debris, lubricating oil should be changed.

      三、油流观察法。取两只量杯,其中一个盛有待检查的润滑油,另一只空放在桌面上,将盛满润滑油的量杯举高离开桌面30-40厘米并倾斜,让润滑油慢慢流到空杯中,观察其流动情况,质量好的润滑油油流时应该是细长、均匀、连绵不断,若出现油流忽快忽慢,时而有大块流下,则说润滑油已变质。

      Oil flow observation method. Take two cups, one of which need to be checked out of the lubricating oil, empty on the desktop, the other will be filled with lubricating oil measuring cup for leave desktop 30 to 40 cm tall and lean, let oil flow slowly to the empty cup, to observe the flow situation, when good quality lubricant oil flow should be long and thin, uniform, continuous, if appear oil flow fast and slow, sometimes with large flow, the said lubricating oil has deteriorated.
