混凝土攪拌車油箱氣孔的作用你知道嗎？

所屬分類：公司新聞發布時間：2021-03-03 來源：http://www.akware.net/ 瀏覽量：0

說起油箱大家應該都不陌生，只要是需要燃油的車輛都是有油箱的，專用車中的攪拌車也不例外，為了防止油箱內的燃油因震蕩而外濺及燃油蒸汽的遺失和外部灰塵的進入，油箱都加蓋而且要密封，但是你們發現沒有，油箱上是有一個小氣孔的，這個氣孔是起什么作用的？大型混凝土攪拌車油箱上如果沒有氣孔會發生什么情況呢？封閉的油箱會因為燃油的消耗而形成一定的真空度，導致油泵失去吸油能力；油箱內氣溫較高的時候，燃油揮發會加大油箱內部的壓力，導致氣壓失衡。

Speaking of the fuel tank, you should be familiar with it. As long as the vehicles need fuel, they all have fuel tanks, and the mixer in special vehicles is no exception. In order to prevent the fuel in the fuel tank from splashing out due to vibration, the loss of fuel vapor and the entry of external dust, the fuel tanks are covered and sealed. But have you found that there is a small air hole on the fuel tank? What is the origin of this air hole What's the effect? What happens if there are no air holes in the tank of large concrete mixer? The closed fuel tank will form a certain degree of vacuum due to the consumption of fuel, resulting in the loss of oil absorption capacity of the pump; when the temperature in the fuel tank is high, the fuel volatilization will increase the internal pressure of the fuel tank, resulting in the imbalance of air pressure.

大型混凝土攪拌車油箱的透氣孔一般都安裝在什么地方？

Where are the air holes in the tank of large concrete mixer generally installed?

1. 安裝在油箱蓋內置閥門上：它可以根據自動開閉，平衡內外氣壓。

1. It is installed on the built-in valve of the oil tank cap: it can balance the internal and external air pressure according to the automatic opening and closing.

2. 安裝在油箱鑰匙孔閥門上：這種在老車型上比較常見。

2. It is installed on the key hole valve of the fuel tank: this kind of valve is more common in old models.

3. 油箱外置通氣孔：現在的商用車大多都是在油箱頂部預留通氣孔，便于吹氣檢查，比如混凝土攪拌車、隨車吊等等。所以如果你的專用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。曾經有個卡友在給車輛放油的時候，忘記打開加油口，然后導致油箱吸癟，這就是真實的教訓，希望各位引起重視。

3. Air vent outside the fuel tank: most commercial vehicles now reserve air vent at the top of the fuel tank to facilitate air blowing inspection, such as concrete mixer, truck mounted crane, etc. So if you have a vent on the tank cap of your special car, once the tank cap is lost, don't seal the tank port at will, and ignore the ventilation. There was once a card friend who forgot to open the gas port when he was filling the car, and then the fuel tank was deflated. This is the real lesson. I hope you will pay attention to it.

攪拌車油箱透氣孔堵塞不僅會導致油箱吸癟，還會導致油泵無法抽取燃油，進而出現熄火、動力不足或者熱機狀態啟動困難等現象，嚴重時還會導致油箱變形破裂，導致燃油泄漏或者火災爆炸等危險。

The blockage of the tank vent will not only lead to the tank deflated, but also lead to the failure of the pump to extract fuel, resulting in flameout, lack of power or difficult start-up in hot engine state. In serious cases, it will also lead to the deformation and rupture of the tank, resulting in fuel leakage or fire and explosion.

大型混凝土攪拌車怎么預防油箱透氣孔堵塞：

How to prevent the air hole of oil tank from blocking for large concrete mixer truck:

1. 經常檢查透氣孔，防患于未然。

1. Check the air vent frequently to prevent trouble.

2. 在加油時留意油箱蓋開啟時的氣流聲，一種是出氣聲，這種聲音是正常的，另一種是吸氣聲，此時要注意，這可能是油箱內的壓力低于外部壓力，油箱透氣孔有可能是堵塞了。

2. When refuelling, pay attention to the air flow sound when the oil tank cap is opened. One is the air out sound, which is normal, and the other is the air in sound. At this time, pay attention to the fact that the pressure in the oil tank is lower than the external pressure, and the air vent of the oil tank may be blocked.

3. 對于鐵質的透氣孔，盡量用紗窗包一下，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 the iron vent, try to wrap it with the screen window. If the vent is a plastic hose, put its mouth down, so as to avoid blocking.
