混凝土搅拌机油箱气孔起到什么作用？

所属分类：行业资讯发布时间：2020-08-17 来源：http://www.sqjituan.cn/ 浏览量：0

大型混凝土搅拌机，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，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，燃油挥发会增大油箱内部的压力，导致气压失衡。

When it comes to large-scale concrete mixer, we should be familiar with the fuel tank. As long as the vehicles that need fuel oil have fuel tank, the mixer truck in the special vehicle is no exception. In order to prevent the fuel in the tank from splashing out due to vibration, the loss of fuel vapor and the entry of external dust, the fuel tank is covered and sealed. But did you find that there is a small air hole on the fuel tank The closed fuel tank will form a certain vacuum degree due to the consumption of fuel, resulting in the loss of oil suction capacity of the oil pump; when the temperature in the tank is high, the fuel volatilization will increase the pressure inside the tank, resulting in air pressure imbalance.

大型混凝土搅拌机油箱的透气孔一般都安装在什么地方？

Where is the air hole of the oil tank of the large concrete mixer 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. Installed on the built-in valve of the oil tank cover: it can open and close automatically to balance the internal and external air pressure.

2. 安装在油箱钥匙孔阀门上：这种在老车型上比较常见。

2. Installed on the valve of the fuel tank key hole: this kind of valve is more common on 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，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 for air blowing inspection, such as concrete mixer truck, truck mounted crane, etc. Therefore, if you have a vent on the fuel tank cap of your special vehicle, once the fuel tank cap is lost, do not seal the fuel tank opening at will, ignoring the ventilation. There was a friend who forgot to open the fuel port when he was discharging fuel to the vehicle, which eventually led to the fuel tank deflating. This is a real lesson. I hope you will pay attention to it.

大型混凝土搅拌机，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。

In large-scale concrete mixer, the blockage of the vent hole of the oil tank will not only lead to the shrinkage of the oil tank, but also lead to the failure of the oil pump to extract fuel oil, and then the phenomenon of flameout, insufficient power or difficult start-up under hot engine condition will occur. In serious cases, the tank will deform and crack, leading to fuel leakage or fire and explosion.

大型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 clogging for large concrete mixer:

1. 经常检查透气孔，防患于未然。

1. Check the air vent frequently to prevent accidents.

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. Pay attention to the air flow sound when the fuel tank cap is opened. One is the air out sound, which is normal, and the other is the suction sound. At this time, it should be noted that the pressure in the fuel tank is lower than the external pressure, and the vent hole of the oil tank may be blocked.

3. 对于铁质的透气孔，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 iron vent, it is better to wrap it with screen. If the vent is a plastic hose, its mouth should face down, so as to avoid blockage.
