空氣質(zhì)量比較差時，有些人會帶上口罩，來過濾掉空氣中的雜質(zhì)。攪拌車也是有“口罩”的，那就是空氣濾清器。那么自上料水泥攪拌車的空氣濾清器什么時候更換？

When the air quality is poor, some people will wear masks to filter impurities in the air. The mixer also has a "mask", that is, an air filter. When will the air filter of the mixer be replaced?

要了解空氣濾清器的工作原理，攪拌車啟動時，發(fā)動機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入到氣缸中。

To understand the working principle of the air filter, 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 inhales air and mixes fuel when the mixer is started, so as to ensure that clean air enters the cylinder.

在理論上每單位體積的燃油燃燒時，大約需要1萬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的更換周期為4.8萬Km,且每2.4萬Km要進行一次常規(guī)檢查；所以保守的維護更換周期為2.4萬Km，攪拌車所處的工作環(huán)境比較差，維護周期要相應(yīng)的減少一些。

In theory, 10000 units of clean air are required for the combustion of fuel per unit volume. In general, the manufacturer recommends that the replacement cycle for normal maintenance of the air filter is 48000 km, and a routine inspection should be carried out every 24000 km; Therefore, the conservative maintenance and replacement cycle is 24000 km, and the working environment of the mixer is relatively 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、殘渣和碳粒。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，風沙區(qū)域，在這些地方工作的攪拌車，它的空氣濾清器的檢驗和更換頻率要高一些。

There are three basic particulate pollutants with different densities in the atmosphere, namely dust, residue and carbon particles. If it is on the open expressway, the dust content is lower than that of the construction site, and the areas with higher dust concentration, namely the construction site, mixing plant, and wind blown sand area, the inspection and replacement frequency of the air filter of the mixer truck working in these areas should be higher.

而在高速公路和交通比較擁堵的區(qū)域，因為攪拌車的排放物集中，所以空氣中碳的含量明顯偏高，對于濾清器的檢查更應(yīng)該仔細，尤其是濾清器的內(nèi)部褶皺處；有時候，濾清器的外部看似清潔，但是其實內(nèi)部已經(jīng)非常臟了，因此須盡快更換。

However, in the expressway and areas with heavy traffic, the carbon content in the air is obviously high because of the concentration of emissions from the mixer, so the filter should be checked more carefully, especially the internal wrinkles of the filter; Sometimes, the outside of the filter looks clean, but the inside is very dirty, so it must be replaced as soon as possible.

攪拌車的工作場所一般是灰塵較大的攪拌站和建筑工地，它的空氣濾清器就顯得尤為重要，對它的保養(yǎng)要十分用心，否則就會造成發(fā)動機的非正常磨損，減少發(fā)動機的使用壽命，所以要定期進行檢查維護并更換，注意事項就來我們網(wǎng)站http://f3328.cn咨詢！

The working place of the mixer is usually the mixing station and construction site with heavy dust. Its air filter is particularly important, and its maintenance should be very careful, otherwise it will cause abnormal wear of the engine and reduce the service life of the engine. Therefore, regular inspection, maintenance and replacement should be carried out. Please visit our website for precautions http://f3328.cn consulting service
