小型混凝土搅拌车是一种可以快速搅拌混凝土的专用车辆，它可以很好地起到防止水泥离析的作用，今天就来给大家介绍一下它的空气过滤器的检查和维修。

Small concrete mixer is a special vehicle that can quickly mix concrete. It can prevent cement segregation. Today, I will introduce the inspection and maintenance of its air filter.

对小型混凝土搅拌车过滤器的检查，应是仔细观察过滤器内部的深层褶皱。从理论上讲，当每单位体积的燃料燃烧时，需要大约10,000单位体积的洁净空气。

The inspection of the filter of the small concrete mixer should be to carefully observe the deep folds inside the filter. Theoretically, when fuel is burned per unit volume, about 10000 unit volumes of clean air are required.

有时候，小型混凝土搅拌车的过滤器表面看起来很干净，但其内部已经很脏，此时必须立即更换。但在高速公路及交通拥堵地区，由于汽车尾气集中，其大气碳含量明显偏高。

Sometimes, the filter surface of the small concrete mixer looks clean, but its interior is already dirty, and it must be replaced immediately. However, in Expressway and traffic congested areas, due to the concentration of automobile exhaust, the atmospheric carbon content is obviously high.

开放高速公路的尘埃含量低于乡村和建筑区的尘埃含量。防止发动机过早磨损，保持佳工作状态。对于粉尘浓度大的场所，如工地，风沙地区，空气过滤器的维修和更换频率要高些。

The dust content of open highways is lower than that of rural and construction areas. Prevent premature engine wear and maintain good working condition. For places with high dust concentration, such as construction sites and sandy areas, the maintenance and replacement frequency of air filters should be higher.

过滤器正常工作情况下。空气过滤器的作用是过滤空气中的灰尘、碳、部门内的水蒸气和其他杂物，在吸入燃油之前，确保洁净的空气进入气缸。大气层内基本粒子污染物有三种，分别是尘埃，残留物和碳颗粒。

Under normal operation of the filter. The function of the air filter is to filter the dust, carbon, water vapor and other sundries in the air, and ensure that clean air enters the cylinder before sucking in the fuel. There are three basic particle pollutants in the atmosphere, namely dust, residue and carbon particles.

预防性维修汽车空气过滤器并不是强调这一点。一般情况下，制造商建议空气过滤器的正常维修更换周期为48,000km，并每24,000km做一次常规检查；建议更换周期为24,000km，但保持不变。

Preventive maintenance of automotive air filters does not emphasize this point. In general, the manufacturer recommends that the normal maintenance and replacement cycle of the air filter is 48000km, and the routine inspection shall be conducted every 24000km; The recommended replacement period is 24000km, but it remains unchanged.

搅拌车空气过滤器的检查和维修保养就讲解到这里，实际上还有其他部件也是需要多加维护的，这样才能让设备更好的使用。

This is all about the inspection and maintenance of the air filter of the mixer truck. In fact, there are other parts that need more maintenance, so that the equipment can be better used.
