The air filter of concrete mixer often goes in and out of the mixing station and construction site with large dust, so its air filter is particularly important. In this kind of dusty place, the air filter is very tired, so its maintenance should be very careful, otherwise it will cause abnormal wear of the engine and reduce the service life of the engine. How can we avoid these problems?

，我们要对空气滤清器的工作原理有所了解，混凝土搅拌机启动时，发动机在吸入空气和燃油混合之前，空气滤清器的功能就是滤掉空气中的灰尘、碳、部分的水蒸气及其它的杂物，从而保证清洁的空气进入到气缸中。在理论上每单位体积的燃油燃烧时，大约需要1万单位体积的清洁空气。一般情况下，制造商空气滤清器正常维护的更换周期为4.8万Km,且每2.4万Km要进行一次常规检查；所以保守的维护更换周期为2.4万KM，混凝土搅拌机所处的工作环境比较差，维护周期要相应的减少一些。

First of all, we need to understand the working principle of the air filter. When the concrete mixer is started, the function of the air filter is to filter out the dust, carbon, part of the water vapor and other impurities in the air before the engine sucks in the air and the fuel is mixed, so as to ensure that the clean air enters the cylinder. In theory, every unit volume of fuel combustion, about 10000 units of clean air. Generally, the manufacturer recommends that the replacement cycle of air filter for normal maintenance is 48000 km, and routine inspection should be carried out every 24000 km; therefore, the conservative replacement cycle is 24000 km, and the working environment of concrete mixer is poor, so the maintenance cycle should be reduced accordingly.
            

在大气中含有三种密度不同的基本颗粒污染物，即灰尘、残渣和碳粒。如果是在开放式的高速公路上，灰尘的含量较建筑工地低一些，灰尘浓度较大的区域，即建筑工地，搅拌站，风沙区域，在这些地方工作的混凝土搅拌机，它的空气滤清器的检验和更换频率要高一些；而在高速公路和交通比较拥堵的区域，因为车辆的排放物集中，所以空气中碳的含量明显偏高，对于滤清器的检查更应该仔细，尤其是滤清器的内部褶皱处；有时候，滤清器的外部看似清洁，但是其实内部已经非常脏了，因此必须尽快更换。

There are three kinds of basic particulate pollutants with different densities in the atmosphere, namely dust, residue and carbon particles. If it is on the open highway, the dust content is lower than that of the construction site, and the dust concentration is higher in the construction site, mixing station and sand area, the frequency of inspection and replacement of the air filter of the concrete mixer working in these areas is higher; while in the highway and traffic congestion area, because of the concentration of vehicle emissions, the air filter of the concrete mixer working in these areas is higher, Therefore, the carbon content in the air is obviously on the high side, so the inspection of the filter should be more careful, especially the internal folds of the filter. Sometimes, the outside of the filter seems clean, but the inside is very dirty, so it must be replaced as soon as possible.
