不少车主担心小型混凝土搅拌机各种保护不周而出现问题，保养按时甚提前，机油选择好企业。但有时还是存在问题，下面小编讲讲，如何利用光照法观察搅拌机机油颜色是否正常。

Many car owners are worried about the problems of small concrete mixers due to inadequate protection. The maintenance is carried out on time or even in advance, and the engine oil is of a good brand. However, there are still some problems. The following section will talk about how to observe whether the oil color of the mixer is normal by using the light method.

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，应更换润滑油。

On a sunny day, use a screwdriver to lift the lubricating oil at a 45 degree angle to the horizontal. Observe the condition of oil drops according to the sunlight. It is good to see clearly that there is no wear debris in the lubricating oil under the sunlight, and it can continue to work. If there are too many wear debris, the lubricating oil should be replaced.

优良的机油呈半透明的黄棕色，机油中有了水则呈褐色，当小型混凝土搅拌机发动机运转一段时间后，机油呈乳白色，并伴有泡沫。

The fine engine oil is translucent yellow brown, and the engine oil is brown if there is water in it. When the engine of a small concrete mixer runs for a period of time, the engine oil is milky white with foam.

机油呈黑色通常是油泥和铁屑过多，或机油中碳粒过多。抽出机油标尺对着光亮处观察刻度线是否清晰，当透过油尺上的机油看不请刻线时，则说明机油过脏，需立即更换。

The black engine oil is usually caused by excessive sludge and iron filings, or excessive carbon particles in the engine oil. Pull out the oil dipstick to the bright place and observe whether the scale line is clear. If the oil on the oil dipstick cannot see the scale line, the oil is too dirty and needs to be replaced immediately.

慢速定性试纸，每次机油检查需试纸一张，也就是每次检查的物料成本很少很少。慢速定性试用于离子和化学成分的测定，它可以测定样品是否含有一定量的某种物质，其中试纸对机油进行检测便能测定机油里面所含的不同成分的状况，从而判断机油是否已经老化。

Slow qualitative test paper, one test paper is required for each oil inspection, which means that the material cost for each inspection is very small. Slow qualitative test is used for the determination of ions and chemical components. It can determine whether the sample contains a certain amount of certain substances. The test paper can detect the condition of different components in the engine oil to determine whether the engine oil has aged.

取出机油尺，在慢速定性试纸滴一滴机油尺上的机油，把试纸水平放置，静待24小时。发现经过24小时静置试纸上会出现下面提到的三个重要的环状区域。

Take out the oil dipstick, drop a drop of engine oil on the slow qualitative test paper, place the test paper horizontally and wait for 24 hours. It is found that the following three important annular areas will appear on the test paper after 24 hours of standing.

在斑点的中心是油内粗颗粒杂质沉积物集中的地方，由沉积环颜色的深浅可粗略判断油被污染的程度。

At the center of the spot is the place where the coarse grain impurities in the oil are concentrated. The degree of oil pollution can be roughly judged by the color of the sedimentary ring.
