Small concrete mixers generally need to be flushed before they are officially put into operation. The purpose of flushing small concrete mixers is to remove the pollutants, metal chips, fiber compounds, iron cores, etc. left in the mixing tank. During the first two hours of operation, even if the system of our small mixer is not completely damaged, it will still cause a series of faults. What are the steps of cleaning the oil circuit of the system?

1.我们需要用一种易干的清洁溶剂清洗油箱，然后再用经过过滤的空气除掉溶剂残渣。

1. We need to clean the oil tank with an easy to dry cleaning solvent, and then remove the solvent residue with filtered air.

2.我们需要清洗系统全部管路，而且在某些情况下需要把管路和接头进行浸渍。

2. We need to clean all the pipelines of the system, and in some cases, we need to impregnate the pipelines and joints.

3.我们需要在集流器上装一块冲洗板以代替精阀，就比如说电液伺服阀等。

3. We need to install a flushing plate on the collector to replace the fine valve, such as electro-hydraulic servo valve.

4.我们需要在管路中装油滤，这样可以保护阀的供油管路和压力管路。

4. We need to install an oil filter in the pipeline to protect the oil supply pipeline and pressure pipeline of the valve.

5.我们还需要检查我们小型搅拌车所有管路尺寸是否合适，连接是否正确。

5. We also need to check whether all pipelines of our small mixer are of proper size and connected correctly.

通过以上的的介绍，我们了解了清洗小型搅拌车系统油路的方法，当然了，冲洗的周期由系统的构造和系统污染程度来决定，若过滤介质的试样没有或是很少外来污染物，则装上新的油滤，卸下冲洗板，装上阀工作！这样做能够使小型搅拌车更好的配合好我们的工作，增加工作效率。

Through the above introduction, we understand the method of cleaning the oil circuit of the small mixer system. Of course, the flushing cycle is determined by the structure of the system and the degree of system pollution. If the sample of the filter medium has no or few foreign pollutants, install a new oil filter, remove the flushing plate and install the valve to work! This can make the small mixer better cooperate with our work and increase work efficiency.
