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.
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.
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.
Mixer drying tank
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.
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.
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.
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.
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.
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.
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.
