空氣濾清器是專用車上的一個重要部件,主要是用于進入發動機的空氣過濾,有了空氣濾清器的作用,才能保證進入車輛發動機的空氣是清潔的,足量的。在日常使用過程中保養是必不可少的,空氣濾清器該如何保養呢?對于自動混凝土攪拌機、隨車起重運輸車等工程車來說,空氣濾清器是非常容易損壞的,因為工程車的作業環境一般都比較差,平時就需要多注意保養。專用車的空氣濾清器比較常見的是慣性式空氣濾清器,此類空濾要從以下兩個方面做保養。
The air filter is an important part of the special vehicle, which is mainly used to filter the air entering the engine. With the function of the air filter, the air entering the vehicle engine can be ensured to be clean and sufficient. In the process of daily use, maintenance is essential, how to maintain the air filter? For the automatic concrete mixer, truck crane truck and other engineering vehicles, the air filter is very easy to damage, because the working environment of the engineering vehicle is generally poor, usually need to pay more attention to maintenance. The more common air filter of special vehicle is inertial air filter. This kind of air filter should be maintained from the following two aspects.
一、自動混凝土攪拌機空氣濾清器清理順序是:
1、 The cleaning sequence of air filter of automatic concrete mixer is as follows:
1. 取下濾芯,用干凈的布或者是橡皮塞堵住濾芯兩端,用軟毛刷沿著遮縫方向刷去濾芯表面的灰塵,敲打濾芯端面,是灰塵脫落。也可使用壓縮空氣從濾芯由內向外吹氣,吹去粘附在濾芯表面的灰塵,清理時禁止使用液體清洗,以防止濾芯粘附灰塵,造成堵塞。
1. Remove the filter element, block both ends of the filter element with a clean cloth or rubber stopper, brush the dust on the surface of the filter element along the seam covering direction with a soft brush, and knock the end face of the filter element to remove the dust. Compressed air can also be used to blow from the inside to the outside of the filter element to blow away the dust adhering to the surface of the filter element. It is forbidden to use liquid cleaning when cleaning, so as to prevent the filter element from sticking dust and causing blockage.
2. 自上料攪拌機檢查主濾芯是否有破損,上下端面是否翹曲不平;檢查主濾芯橡膠密封圈是否破損;檢查主濾芯內側是否有灰塵,如果有上述任一問題,就需要更換主濾芯。
2. From the feeding mixer, check whether the main filter element is damaged and whether the upper and lower end faces are warped; check whether the rubber sealing ring of the main filter element is damaged; check whether there is dust inside the main filter element. If there is any of the above problems, the main filter element needs to be replaced.
3. 使用強光手電筒檢查濾芯是否破損,檢查時不要拆下濾芯,若濾芯有破損應立即更換,在清理濾芯殼體的過程中,要使用干凈抹布將殼體內壁擦拭干凈,并檢查排塵閥是否正常排塵。
3. Use a flashlight to check whether the filter element is damaged. Do not remove the safety filter element. If the safety filter element is damaged, replace it immediately. In the process of cleaning the shell of the filter element, wipe the inner wall of the shell with a clean cloth, and check whether the dust valve is discharging dust normally.
二、自動混凝土攪拌機空氣濾清器也不能清理太過頻繁
2、 The air filter of automatic concrete mixer can not be cleaned too frequently
假如空氣濾清器清理太過頻繁,濾芯的過濾能力就得不到充分的額發揮,這樣不僅使得進入發動機的灰塵數量增多,造成發動機異常磨損,還會造成濾芯的早期損壞。濾芯在每次清理后,其容灰的能力就會降低20%-40%,隨著清理次數的增加,濾芯的容灰量就會逐漸降低,當濾芯清理5次以后,容灰量就基本沒有了,此時就必須更換空濾了??諝鉃V清器是攪拌機配件的一種,雖然不算昂貴,但是如果損壞就會嚴重影響發動機的正常工作,因此建議駕駛工程車的朋友一定要定期的清理空氣濾清器。
If the air filter is cleaned too frequently, the filtering capacity of the filter element will not be fully utilized, which will not only increase the amount of dust entering the engine, cause abnormal wear of the engine, but also cause early damage to the filter element. After each cleaning of the filter element, its ash holding capacity will be reduced by 20% - 40%. With the increase of cleaning times, the ash holding capacity of the filter element will be gradually reduced. When the filter element is cleaned for 5 times, the ash holding capacity will be basically gone. At this time, the air filter must be replaced. Air filter is a kind of mixer accessories, although the price is not expensive, but if it is damaged, it will seriously affect the normal work of the engine, so it is recommended that friends driving engineering vehicles must regularly clean the air filter.
