There are many parts on the large-scale concrete mixer, such as the dryer. Many people do not know much about the dryer. If there is a problem with the dryer, it will lose its function of absorbing moisture in the air, and it may enter the air system of the mixer, bringing greater safety and property losses. For large concrete mixers, when purchasing drying tanks, try to select the drying tanks with small and many air holes and strong structure. It is necessary to know that the dryer needs to be replaced after a long time of use, so when to replace it is a key issue. Let's take a look at the following:

不同的车辆工况是不同的，而且不同厂家的干燥罐使用寿命也是不同的，在更换周期上没有统一的标准，不过大家可以使用一些简单的方来判断干燥罐是否该更换。，我们可以从气罐下手，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。因为阀门正好位于气罐底部。同时水的比重较大，如果干燥器失效，气路中的湿气因为重力自然会攒到气罐底部，也就是阀门上方。

The working conditions of different vehicles are different, and the service life of drying tanks of different manufacturers is also different. There is no unified standard on the replacement cycle. However, we can use some simple methods to judge whether the drying tank should be replaced. First of all, we can start from the air tank and use the vent valve at the bottom of the gas tank to check whether the bottom of the gas tank is wet or there is water. Because the valve is just at the bottom of the tank. At the same time, the proportion of water is relatively large. If the dryer fails, the moisture in the gas path will naturally accumulate to the bottom of the gas tank, that is, above the valve.

还有一种方法就是，通过释放各个制动分泵的卸压阀来检查车辆气路中是否含水。尤其是在冬天，气温低，一定要注意检查管路中是否有水，防止制动失效，干燥罐渗漏，劣质的干燥罐是比较容易渗漏的，而且如果是在气候潮湿的南方，干燥罐的使用寿命也会缩短。相反北方由于气候比较干燥，北方的搅拌车的干燥罐使用寿命就比较长。

Another method is to check whether there is water in the air path of the vehicle by releasing the pressure relief valve of each brake cylinder. Especially in winter, when the temperature is low, we must pay attention to check whether there is water in the pipeline to prevent brake failure and leakage of drying tank. Poor quality drying tank is easy to leak, and if it is in the South with humid climate, the service life of drying tank will be shortened. On the contrary, due to the relatively dry climate in the north, the service life of the drying tank of the mixer truck in the north is relatively long.

大型混凝土搅拌机干燥罐更换方法：将搅拌车气罐底部堆积的油渍或水渍放干净后，换上新的干燥罐即可，在日常使用中，要养成经常查看气罐放气阀的良好习惯，还可以安装一个拉环，那么不仅方便日常检查，而且也可以时不时的转动两下，让气阀密封更加均匀，达到避免漏气的效果。

Replacement method for drying tank of large-scale concrete mixer: the oil or water stains accumulated at the bottom of the air tank of the mixer truck can be replaced with a new drying tank. In daily use, it is necessary to form a good habit of frequently checking the air tank vent valve, and a pull ring can be installed, which is not only convenient for daily inspection, but also can be rotated twice from time to time to make the air valve seal more uniform To avoid air leakage.

大型混凝土搅拌机提醒大家：干燥罐虽小，但是其作用却不小，大家在平时保养车辆的时候，不仅要做好大件的保养，一些零碎的小部件也要做好保养，这样才能保证车辆的使用寿命。

Large concrete mixer reminds you: Although the drying tank is small, its role is not small, we should not only do a good job in the maintenance of vehicles, but also do a good job in the maintenance of some small parts, so as to ensure the service life of vehicles.
