混凝土搅拌机，说起油箱大家应该都不陌生，只要是需要燃油的车辆都是有油箱的，专用车中的搅拌车也不例外，为了防止油箱内的燃油因震荡而外溅及燃油蒸汽的遗失和外部灰尘的进入，油箱都加盖而且要密封，但是你们发现没有，油箱上是有一个小气孔的，这个气孔是起什么作用的？混凝土搅拌机油箱上如果没有气孔会发生什么情况呢？封闭的油箱会因为燃油的消耗而形成一定的真空度，导致油泵失去吸油能力；油箱内气温较高的时候，燃油挥发会加大油箱内部的压力，导致气压失衡。
The concrete mixer, speaking of the fuel tank, should be familiar to everyone. As long as the vehicles need fuel, they all have a fuel tank, and the mixer in the special vehicle 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 did you find that there is a small air hole on the fuel tank, which is very important What is the function of a stoma? What happens if there are no air holes in the tank of the 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.
混凝土搅拌机油箱的透气孔一般都安装在什么地方？
Where are the air holes of concrete mixer oil tank generally installed?
1. 安装在油箱盖内置阀门上：它可以根据自动开闭，平衡内外气压。
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. 安装在油箱钥匙孔阀门上：这种在老车型上比较常见。
2. It is installed on the key hole valve of the fuel tank: this kind of valve is more common in old models.
3. 油箱外置通气孔：现在的商用车大多都是在油箱顶部预留通气孔，便于吹气检查，比如混凝土搅拌车、随车吊等等。所以如果你的专用车油箱盖上带有透气孔，一旦油箱盖丢失切勿随意封死油箱口，而忽视了通气性。曾经有个卡友在给车辆放油的时候，忘记打开加油口，然后导致油箱吸瘪，这就是真实的教训，希望各位引起重视。
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.
油箱透气孔堵塞不仅会导致油箱吸瘪，还会导致油泵无法抽取燃油，进而出现熄火、动力不足或者热机状态启动困难等现象，严重时还会导致油箱变形破裂，导致燃油泄漏或者火灾爆炸等危险。
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, leading to fuel leakage or fire and explosion.
混凝土搅拌机怎么预防油箱透气孔堵塞：
How to prevent the air hole of oil tank from blocking in concrete mixer:
1. 经常检查透气孔，防患于未然。
1. Check the air vent frequently to prevent trouble.
2. 在加油时留意油箱盖开启时的气流声，一种是出气声，这种声音是正常的，另一种是吸气声，此时要注意，这可能是油箱内的压力低于外部压力，油箱透气孔有可能是堵塞了。
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. 对于铁质的透气孔，尽量用纱窗包一下，如果是透气孔是塑料软管，那就将其口朝下，这样可以避免堵塞。
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.
The above is the introduction of the function of the air hole in the tank of the concrete mixer, hoping to help you. For more wonderful information, please click our website: Zhongke mixer https://www.cnzkjf.com
