要放干净搅拌机机油的原因是啥?发动机工作时，机油会受到各种金属的高温燃烧和催化作用，并逐渐老化，产生积炭、油泥等对发动机有害的物质。它们在发动机的不同部位产生，积聚在油路中，会加速磨损，导致润滑不良，影响发动机的使用寿命。

What is the reason to drain the mixer oil? When the engine is working, the engine oil will be subject to high-temperature combustion and catalysis of various metals, and will gradually age, producing carbon deposits, sludge and other substances harmful to the engine. They are produced in different parts of the engine and accumulate in the oil circuit, which will accelerate wear, cause poor lubrication and affect the service life of the engine.

所以说要掌握正确的换油周期及相关知识，作为车主，不仅要学会选择正确的机油，还要掌握一些自动混凝土搅拌机的换油周期及相关知识。

Therefore, we should master the correct oil change cycle and related knowledge. As a car owner, we should not only learn to choose the correct oil, but also master some oil change cycles and related knowledge of automatic concrete mixer.

如果说发动机是汽车的心脏，那么机油就是汽车的血液。起到润滑、清洗、冷却、防腐、防锈、密封等作用。发动机内有大量的金属表面相互摩擦，因此需要润滑油来减少磨损，而金属摩擦产生的碎屑也会聚集和释放，这是造成机油发黑的主要原因。

If the engine is the heart of the car, then the oil is the blood of the car. It has the functions of lubrication, cleaning, cooling, corrosion prevention, rust prevention, sealing, etc. A large number of metal surfaces in the engine rub against each other, so lubricating oil is needed to reduce wear, and the debris generated by metal friction will also accumulate and release, which is the main reason for the blackening of engine oil.

在维护过程中，应排空机油15分钟以上。通常，我们出去保养的时候，不注意排油多长时间。为了追求效率，有的店放油5-6分钟，导致油渣，对车的影响很大。建议您在保养时提出“机油排放15分钟以上”的要求。新车尤其重要。车主一定要注意。

During maintenance, drain the engine oil for more than 15 minutes. Usually, when we go out for maintenance, we don't pay attention to how long it takes to drain the oil. In order to pursue efficiency, some stores drain oil for 5-6 minutes, resulting in oil residue, which has a great impact on the car. It is recommended that you put forward the requirement of "oil drainage for more than 15 minutes" during maintenance. New cars are particularly important. Car owners must pay attention.

新手学习如何更换发动机机油：

Beginners learn how to change engine oil:

选择合适的机油而不是贵的机油。

Choose the right oil instead of expensive oil.

换油前，好开车出去走走，让机油均匀润滑发动机，并将发动机内部沉淀的杂质带出来。

Before changing the oil, drive out for a walk, let the engine oil lubricate the engine evenly, and bring out the impurities precipitated inside the engine.

打开发动机底部的放油口，开始放油。放完机油后，务必排空发动机15分钟，以便将发动机中的残余机油完全排空。

Open the oil drain at the bottom of the engine and start to drain the oil. After draining the oil, be sure to drain the engine for 15 minutes in order to completely drain the residual oil in the engine.

仔细观察流出的机油。如果油非常粘稠、分层且有轻微气味，则应缩短换油周期。如果有强烈的汽油味，说明发动机燃烧室密封性不好。好找师傅修一下。

Carefully observe the oil flowing out. If the oil is very viscous, stratified and has a slight smell, shorten the oil change interval. If there is a strong smell of gasoline, the engine combustion chamber is not well sealed. I can find a master to repair it.

关闭油口螺栓并更换新的机油滤清器。

Close the oil port bolt and replace with a new oil filter.

打开机油加注口，注入新的发动机机油，检查油尺的上限。

Open the oil filler, fill in new engine oil, and check the upper limit of the dipstick.

加油后，启动发动机，启动汽车，怠速几分钟后关闭发动机。再次检查油尺，看是否需要补充机油。更多关于搅拌机换油的事项您可以关注网站http://www.zkhntjbc.com看看！

After refueling, start the engine, start the car, and turn off the engine after idling for a few minutes. Check the dipstick again to see if it is necessary to replenish oil. For more information about the oil change of the mixer, you can follow the website http://www.zkhntjbc.com have a look!
