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:
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.
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.
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.
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.
