Many users don't care about this item. Everyone is familiar with the drying tank of cement mixer truck. It is used to filter the water vapor in the compressed air in the air circuit system to prevent the air reservoir and various pump valves from corrosion. Therefore, whether the drying tank of mixer truck can work normally directly affects the performance of brake.

现实中却有多卡友因为对干燥罐认识不全，而经常忽略它的存在。搅拌车干燥罐虽然不贵，但是很多用户还是能省就省，对干燥罐的品质也无所谓，只要有一个能用就行，有的甚几年都不换一次。

In reality, there are many card friends who often ignore the existence of drying pot because they don't fully understand it. Although the drying tank of mixer truck is not expensive, many users can save, and it doesn't matter about the quality of the drying tank. As long as one can be used, some don't even change it once a few years.

干燥罐一定要买企业的，有个司机朋友刚换了没多久的劣质干燥罐就失效了，结果刹车分泵内进水结冰导致刹车失灵。

We must buy a brand of drying tank. A friend of the driver just changed the inferior drying tank and it failed. As a result, the water in the brake cylinder was frozen, resulting in brake failure.

搅拌车干燥罐

Mixer drying tank

水泥搅拌车更换干燥罐的操作并不繁琐，利用气罐底部的放气阀门，来查看气罐底部是否潮湿，或者有水。如果干燥罐失效，打开阀门之后会有水流出，应该立即更换新的干燥罐。

The operation of replacing the drying tank of the cement mixer is not cumbersome. Use the vent valve at the bottom of the air tank to check whether the bottom of the air tank is wet or there is water. If the drying tank fails, water will flow out after opening the valve, and a new drying tank should be replaced immediately.

好多人都是只要不出问题，几年可能都不会换一次。并且不同企业的干燥罐使用寿命不一样，而且车辆行驶的气候环境也有差异，更换的周期就很难统一。

Many people may not change once in a few years as long as there is no problem. Moreover, the service life of drying cans of different brands is different, and the climatic environment of vehicles is also different, so it is difficult to unify the replacement cycle.

如果搅拌车司机们实在不知道何时该更换，可以通过查看储气筒是否有积水的方法来判断。但是在这里也要提醒司机朋友们，因为搅拌车干燥罐连接着气路，罐体内部与外界有一定的压力差，压缩空气未排空时冒然拆卸，压缩空气瞬间释放，易对拆卸人员造成伤害。

If the mixer truck drivers really don't know when to replace, they can judge by checking whether there is water in the air reservoir. However, it is also necessary to remind drivers here that because the drying tank of the mixer truck is connected with the gas circuit, there is a certain pressure difference between the tank and the outside world. When the compressed air is not emptied, it is disassembled rashly, and the compressed air is released instantly, which is easy to cause harm to the disassembly personnel.

所以，一定要排空储气筒内空气（反复踩踏刹车，直气压表读数归零），才可以对干燥罐进行拆卸。借助专用的扳手将干燥罐拆卸下来之后，可以在底座上看到有星星点点的水珠，可见压缩空气的湿度还是很大的。

Therefore, be sure to empty the air in the air reservoir (step on the brake repeatedly until the barometer reading returns to zero), and then disassemble the drying tank. After the drying tank is removed with the help of a special wrench, you can see scattered water droplets on the base, which shows that the humidity of the compressed air is still very high.

如果干燥罐的过滤效果差的话，这些液态水就会由气路进入到刹车的各个泵阀。在安装新的干燥罐之前，要将底座上面清理一下，防止油污进入新罐的内部，影响性能。

If the filtering effect of the drying tank is poor, the liquid water will enter each pump valve of the brake from the gas circuit. Before installing a new drying tank, first clean the base to prevent oil from entering the interior of the new tank and affecting the dehumidification performance.

然后在新干燥罐下面的橡胶垫圈上要涂抹一层机油，起到润滑的作用，防止安装时损坏橡胶垫圈。

Then apply a layer of engine oil on the rubber washer under the new drying tank to lubricate and prevent damage to the rubber washer during installation.

搅拌车影响刹车性能的原因有很多，搅拌车干燥罐就是不可忽略的一个重要因素，如果使用劣质产品，或者长时间不更换导致性能丧失，将会严重影响整车的制动。

There are many reasons that affect the braking performance of mixer truck. The drying tank of mixer truck is an important factor that can not be ignored. If inferior products are used or the dehumidification performance is lost due to long-term non replacement, the braking of the whole vehicle will be seriously affected.
