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:

不同的車輛工況是不同的，而且不同廠家的干燥罐使用壽命也是不同的，在更換周期上沒有統一的標準，不過大家可以使用一些簡單的方來判斷干燥罐是否該更換。首先，我們可以從氣罐下手，利用氣罐底部的放氣閥門，來查看氣罐底部是否潮濕，或者有水。因為閥門正好位于氣罐底部。同時水的比重較大，如果干燥器失效，氣路中的濕氣因為重力自然會攢到氣罐底部，也就是閥門上方。

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.

還有一種方法就是，通過釋放各個制動分泵的卸壓閥來檢查車輛氣路中是否含水。尤其是在冬天，氣溫低，一定要注意檢查管路中是否有水，防止制動失效，干燥罐滲漏，劣質的干燥罐是比較容易滲漏的，而且如果是在氣候潮濕的南方，干燥罐的使用壽命也會縮短。相反北方由于氣候比較干燥，北方的攪拌車的干燥罐使用壽命就比較長。

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.

大型混凝土攪拌機干燥罐更換方法：將攪拌車氣罐底部堆積的油漬或水漬放干凈后，換上新的干燥罐即可，在日常使用中，要養成經常查看氣罐放氣閥的良好習慣，還可以安裝一個拉環，那么不僅方便日常檢查，而且也可以時不時的轉動兩下，讓氣閥密封更加均勻，達到避免漏氣的效果。

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.

大型混凝土攪拌機提醒大家：干燥罐雖小，但是其作用卻不小，大家在平時保養車輛的時候，不僅要做好大件的保養，一些零碎的小部件也要做好保養，這樣才能保證車輛的使用壽命。

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.
