For the drying tank of concrete mixer truck, people who drive the mixer are not unfamiliar. It is used to filter water vapor in compressed air in the air path system to prevent the air reservoir and various pump valves from being corroded. However, I found that many users do not care about this. Therefore, whether the mixer dryer can work normally will directly affect the performance of the brake. In reality, there are some docayou who often ignore its existence because they don't have a comprehensive understanding of the dryer. Although the mixer dryer is not expensive, many users can save money, and the quality of the dryer is indifferent. As long as one can be used, some even do not change it every few years.

干燥罐一定要买正品的，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,带来更大的和财产损失。在选购混凝土搅拌机干燥罐的时候，尽量挑选出气孔细而多、结构较强的干燥罐，要知道干燥器使用时间长了也是需要更换的，那么什么时候更换是个关键问题，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。下面我们就一起来了解一下。

The dryer must be genuine. A driver's friend had just replaced a poor quality dryer which failed. As a result, the brake failed due to water freezing in the brake cylinder, which brought greater safety and property losses. When purchasing the drying tank of concrete mixer truck, try to select the dryer with small and many air holes and strong structure. You should know that the dryer needs to be replaced after a long service life. When to replace the dryer is a key issue. Different vehicle conditions are different, and the service life of drying tank of different manufacturers is also different. There is no unified standard on the replacement cycle However, you can use some simple methods to determine whether the dryer should be replaced. Let's take a look at it.

How to judge whether the drying tank of concrete mixer needs to be replaced

一、判断混凝土搅拌机干燥罐是否需要更换的方法

1、 The method of judging whether the drying tank of concrete mixer needs to be replaced

混凝土搅拌机替换干燥罐的操作并不繁琐，利用气罐底部的放气阀门，来检查气罐底部是否湿润，或许有水。假如干燥罐失效，打开阀门之后会有水流出，应该当即替换新的干燥罐。好多人都是只需不出问题，几年可能都不会换一次。并且不同企业的干燥罐运用寿命不一样，并且车辆行驶的气候环境也有差异，替换的周期就很难一致。假如搅拌车司机们确实不知道何时该替换，能够通过检查储气筒是否有积水的方法来判断。可是在这里也要提示司机朋友们，由于搅拌车干燥罐连接着气路，罐体内部与外界有必定的压力差，压缩空气未排空时冒然拆开，压缩空气瞬间释放，极易对拆开人员形成损伤。

The operation of concrete mixer replacing drying tank 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 not, and there may be water. If the drying tank fails and water will flow out after opening the valve, a new drying tank should be replaced immediately. Many people just don't need to have problems, and they may not change them for several years. Moreover, the service life of different brands of drying cans is different, and the climate environment of vehicles is also different, so the replacement cycle is difficult to be consistent. If the mixer drivers really don't know when to replace it, they can judge by checking whether there is water in the air reservoir. However, it is also necessary to remind the drivers that since the drying tank of the mixer truck is connected with the gas path, there is a certain pressure difference between the inside and outside of the tank. When the compressed air is not emptied, the compressed air is released instantly, which is very easy to cause damage to the disassembler.

1、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，那么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。

1. 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 has water. Because the valve is just at the bottom of the tank. At the same time, the proportion of water is large, if the dryer fails, then the moisture in the gas path will naturally accumulate to the bottom of the gas tank, that is, above the valve.

2、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。

2. 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.

混凝土搅拌机干燥罐的更换方法：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 concrete mixer truck: after the oil or water stains accumulated at the bottom of the air tank of the mixer truck are removed, a new drying tank can be replaced. 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.

搅拌车司机提醒大家：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。搅拌车影响刹车性能的原因有很多，搅拌车干燥罐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性。天气即将转冷，尤其是跑北方地区的卡友们，应该时刻注意干燥罐工作是否正常，及时进行更换，避免因小失大。

The driver of the mixer truck reminds us that although the dryer is small, its role is not small. When maintaining the vehicle at ordinary times, we should not only do a good job in the maintenance of large parts, but also some small parts, so as to ensure the service life of the vehicle. There are many reasons that affect the braking performance of the mixer, and the dryer of the mixer is absolutely an important factor that can not be ignored. If the use of inferior products, or the loss of dehumidification performance due to long-term non replacement, will seriously affect the braking safety of the whole vehicle. The weather is about to turn cold, especially those who run in the northern area. They should always pay attention to whether the drying tank works normally or not, and replace it in time, so as to avoid making a small loss.
