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?

，我們要對(duì)空氣濾清器的工作原理有所了解，混凝土攪拌機(jī)啟動(dòng)時(shí)，發(fā)動(dòng)機(jī)在吸入空氣和燃油混合之前，空氣濾清器的功能就是濾掉空氣中的灰塵、碳、部分的水蒸氣及其它的雜物，從而保證清潔的空氣進(jìn)入到氣缸中。在理論上每單位體積的燃油燃燒時(shí)，大約需要1萬(wàn)單位體積的清潔空氣。一般情況下，制造商空氣濾清器正常維護(hù)的更換周期為4.8萬(wàn)Km,且每2.4萬(wàn)Km要進(jìn)行一次常規(guī)檢查；所以保守的維護(hù)更換周期為2.4萬(wàn)KM，混凝土攪拌機(jī)所處的工作環(huán)境比較差，維護(hù)周期要相應(yīng)的減少一些。

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.
            

在大氣中含有三種密度不同的基本顆粒污染物，即灰塵、殘?jiān)吞剂?。如果是在開放式的高速公路上，灰塵的含量較建筑工地低一些，灰塵濃度較大的區(qū)域，即建筑工地，攪拌站，風(fēng)沙區(qū)域，在這些地方工作的混凝土攪拌機(jī)，它的空氣濾清器的檢驗(yàn)和更換頻率要高一些；而在高速公路和交通比較擁堵的區(qū)域，因?yàn)檐囕v的排放物集中，所以空氣中碳的含量明顯偏高，對(duì)于濾清器的檢查更應(yīng)該仔細(xì)，尤其是濾清器的內(nèi)部褶皺處；有時(shí)候，濾清器的外部看似清潔，但是其實(shí)內(nèi)部已經(jīng)非常臟了，因此必須盡快更換。

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.
