小型混凝土攪拌車是一種可以快速攪拌混凝土的專用車輛，它可以很好地起到防止水泥離析的作用，今天就來給大家介紹一下它的空氣過濾器的檢查和維修。

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.

對小型混凝土攪拌車過濾器的檢查，應(yīng)是仔細(xì)觀察過濾器內(nèi)部的深層褶皺。從理論上講，當(dāng)每單位體積的燃料燃燒時(shí)，需要大約10,000單位體積的潔凈空氣。

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.

有時(shí)候，小型混凝土攪拌車的過濾器表面看起來很干凈，但其內(nèi)部已經(jīng)很臟，此時(shí)必須立即更換。但在高速公路及交通擁堵地區(qū)，由于汽車尾氣集中，其大氣碳含量明顯偏高。

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.

開放高速公路的塵埃含量低于鄉(xiāng)村和建筑區(qū)的塵埃含量。防止發(fā)動機(jī)過早磨損，保持佳工作狀態(tài)。對于粉塵濃度大的場所，如工地，風(fēng)沙地區(qū)，空氣過濾器的維修和更換頻率要高些。

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.

過濾器正常工作情況下。空氣過濾器的作用是過濾空氣中的灰塵、碳、部門內(nèi)的水蒸氣和其他雜物，在吸入燃油之前，確保潔凈的空氣進(jìn)入氣缸。大氣層內(nèi)基本粒子污染物有三種，分別是塵埃，殘留物和碳顆粒。

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.

預(yù)防性維修汽車空氣過濾器并不是強(qiáng)調(diào)這一點(diǎn)。一般情況下，制造商建議空氣過濾器的正常維修更換周期為48,000km，并每24,000km做一次常規(guī)檢查；建議更換周期為24,000km，但保持不變。

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.

攪拌車空氣過濾器的檢查和維修保養(yǎng)就講解到這里，實(shí)際上還有其他部件也是需要多加維護(hù)的，這樣才能讓設(shè)備更好的使用。

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.
