Factors affecting brake performance of semi-trailer

There are many factors that affect the performance of truck brakes. Let's take a look at one that is often overlooked, and that is the drying tank.

Poor quality drying tanks will lose their ability to absorb moisture in the air after being used for a very short time. Some drying tanks will also allow the desiccant to enter the vehicle's air path system, bringing greater safety and property damage.

When selecting the drying tank, the driver should try to select the drying tank with thin air outlet and strong structure. After all, compared with the capacity of desiccant particles that can not be seen inside, this discrimination method is more simple and intuitive.

How long does it take to replace the drying tank? I believe this is also a question that many drivers want to know. However, due to the different working conditions of each vehicle and the different life of the drying tank from different manufacturers, it is difficult to give a unified standard on the replacement cycle. However, today I will teach you a tip, so that you can always know whether your drying tank should be replaced.

The way to check whether the drying tank is expired is to start from the tank and use the vent valve at the bottom of the tank to check whether the bottom of the tank is wet or has water. Because the valve sits right at the bottom of the tank. At the same time, the proportion of water is large. If the drying tank fails, the moisture in the air path will naturally accumulate to the bottom of the tank, which is above the valve, due to gravity.

At the same time, it is also possible to check whether there is water in the vehicle air path by releasing the pressure relief valve of each brake pump. Especially in the cold weather season must pay attention to check whether there is water in the pipeline, to prevent brake failure.

Drying tank leakage is obvious, in addition to the use of inferior drying tank, short life, but also related to the working condition in the humid place in the south, because the air humidity is greater than in the north, so the drying tank life is shorter than in the north.

After the oil or water stains accumulated at the bottom of the gas tank are cleaned, a new dry tank can be replaced. In daily use, a good habit of often checking the gas tank vent valve is formed. If a pull ring is installed again, it is not only convenient for daily inspection, but also can rotate two times from time to time to make the valve seal more evenly and avoid the effect of air leakage.

Through this tip, we can know at any time whether the service life of the drying tank is expired, which is convenient for the daily replacement of the drying tank and avoid the economic loss caused by the advance or delay.
