說(shuō)起油箱大家應(yīng)該都不陌生，只要是需要燃油的車輛都是有油箱的，專用車中的
自上料水泥攪拌車也不例外，為了防止油箱內(nèi)的燃油因震蕩而外濺及燃油蒸汽的遺失和外部灰塵的進(jìn)入，油箱都加蓋而且要密封，但是你們發(fā)現(xiàn)沒(méi)有，油箱上是有一個(gè)小氣孔的，那這個(gè)氣孔是起什么作用的呢？
When it comes to fuel tanks, everyone should be familiar with them. Any vehicle that needs fuel has a fuel tank, and the self loading cement mixer truck in specialized vehicles is no exception. In order to prevent the fuel inside the tank from splashing out due to vibration, loss of fuel vapor, and entry of external dust, the fuel tanks are all covered and sealed. However, have you noticed that there is a small air hole on the fuel tank? What is the purpose of this air hole?
油箱上如果沒(méi)有氣孔會(huì)發(fā)生什么情況呢？
What would happen if there were no air holes on the fuel tank?
封閉的油箱會(huì)因?yàn)槿加偷南亩纬梢欢ǖ恼婵斩?，?dǎo)致油泵失去吸油能力；油箱內(nèi)氣溫較高的時(shí)候，燃油揮發(fā)會(huì)增大油箱內(nèi)部的壓力，導(dǎo)致氣壓失衡。
A closed fuel tank will form a certain degree of vacuum due to fuel consumption, causing the oil pump to lose its suction capacity; When the temperature inside the fuel tank is high, fuel evaporation will increase the pressure inside the fuel tank, leading to an imbalance in air pressure.
那么油箱的透氣孔一般都安裝在油箱的什么地方呢？
So where are the ventilation holes of the fuel tank usually installed?
1.安裝在油箱蓋內(nèi)置閥門(mén)上：它可以根據(jù)自動(dòng)開(kāi)閉，平衡內(nèi)外氣壓。
1. Installed on the valve inside the fuel tank cover: it can automatically open and close, balancing internal and external air pressure.
2.安裝在油箱鑰匙孔閥門(mén)上：這種在老車型上比較常見(jiàn)。
2. Installed on the fuel tank keyhole valve: This is more common on older models.
3.油箱外置通氣孔：現(xiàn)在的商用車大多都是在油箱頂部預(yù)留通氣孔，便于吹氣檢查，比如混凝土攪拌車、隨車吊等等。
3. External vent holes in fuel tanks: Most commercial vehicles nowadays reserve vent holes at the top of the fuel tank for easy air blowing inspection, such as concrete mixer trucks, truck mounted cranes, etc.
所以如果你的自上料水泥攪拌車油箱蓋上帶有透氣孔，一旦油箱蓋丟失切勿隨意封死油箱口，而忽視了通氣性。曾經(jīng)有個(gè)卡友在給車輛放油的時(shí)候，忘記打開(kāi)加油口，后導(dǎo)致油箱吸癟，這就是真實(shí)的教訓(xùn)，希望各位卡友們引起重視。
So if your self feeding cement mixer truck has a vent hole on the fuel tank cap, do not seal the fuel tank port arbitrarily once the fuel tank cap is lost, ignoring the ventilation. Once, there was a card user who forgot to open the fuel filler when draining a vehicle, which caused the fuel tank to deflate. This is a real lesson, and I hope all card users will take it seriously.
油箱透氣孔堵塞不僅會(huì)導(dǎo)致油箱吸癟，還會(huì)導(dǎo)致油泵無(wú)法抽取燃油，進(jìn)而出現(xiàn)熄火、動(dòng)力不足或者熱機(jī)狀態(tài)啟動(dòng)困難等現(xiàn)象，嚴(yán)重時(shí)還會(huì)導(dǎo)致油箱變形破裂，導(dǎo)致燃油泄漏或者火災(zāi)爆炸等危險(xiǎn)。
Blocking the vent holes of the fuel tank not only causes the fuel tank to suck out, but also causes the oil pump to be unable to extract fuel, resulting in phenomena such as stalling, insufficient power, or difficulty starting the hot engine. In severe cases, it can also cause deformation and rupture of the fuel tank, leading to fuel leakage, fire and explosion hazards.
下面說(shuō)一下怎么預(yù)防油箱透氣孔堵塞：
Here's how to prevent clogging of the fuel tank vent:
1.經(jīng)常檢查透氣孔，防患于未然。
1. Regularly check the ventilation holes to prevent potential problems.
2.在加油時(shí)留意油箱蓋開(kāi)啟時(shí)的氣流聲，一種是出氣聲，這種聲音是正常的，另一種是吸氣聲，此時(shí)要注意，這可能是油箱內(nèi)的壓力低于外部壓力，油箱透氣孔有可能是堵塞了。
2. When refueling, pay attention to the sound of airflow when the fuel tank cap is opened. One is the sound of exhalation, which is normal, and the other is the sound of inhalation. At this time, it should be noted that the pressure inside the fuel tank may be lower than the external pressure, and the fuel tank vent may be blocked.
3.對(duì)于鐵質(zhì)的透氣孔，好用紗窗包一下，如果是透氣孔是塑料軟管，那就將其口朝下，這樣可以避免堵塞。
3. For iron breathable holes, it is easy to wrap them with a screen window. If the breathable hole is a plastic hose, the mouth should be facing downwards to avoid blockage.
From the above, it can be seen that the function of the fuel tank vent is still significant. It is important to pay more attention to the fuel tank vent of your car in daily life. If you have any doubts or needs, please come to our website http://www.sansungmobile.cn Consult!
