When to replace the truck dryer

The truck drying tank is a device used to filter the water vapor in the compressed air in the air circuit system, which can prevent the air reservoir and various pump valves from being corroded. Truck dryers can also remove harmful pollutants, such as oil and moisture, which may damage air valves, air brakes, and even engines. Therefore, whether the truck dryer can work normally will directly affect the braking performance. Continue reading to understand the importance of truck dryers and replacement standards.

What is a truck air dryer?

Truck dryer is a mechanical device that vaporizes moisture and other volatile liquid components in the material by heating to obtain a specified content of solid material. The purpose of drying is to meet the needs of material use or further processing, and the dried material is also easy to transport and store. The air dryer is located between the compressor and the air storage tank. It is used to cool, filter and dry the compressed air, remove water vapor, oil, dust and other impurities, and provide dry and clean air for the brake system.

Truck dryer is a regenerative dryer, which uses molecular sieve as desiccant. Molecular sieve is a synthetic desiccant product with strong adsorption of water molecules. Molecular sieve is a kind of alkali metal aluminosilicate compound with microporous structure. There are many uniform pores and cavities in the structure. It is because of these structures that the air dryer can fully play its role.

What are the symptoms of a broken dryer?

1. The air conditioning duct is dirty and blocked.
Impurities or moisture in the system pipes freeze and the pipes are blocked. After blockage, the cooling effect becomes very bad or cannot be cooled normally.
2. The truck dryer cannot be pumped
Because the working principle of the dryer is to dry and filter the compressed gas from the air pump, so that impurities and moisture cannot enter the brake system. If the dryer breaks down, the air pump will naturally fail to breathe.
3. Affect the braking effect.
If the water in the automobile pipeline is not absorbed, the water in the air will become water after high-pressure pressure, which will rust the pipeline joints and directly affect the brakes.

Truck dryers are the same as other vehicles-they all require regular maintenance. Without an expert diagnosis, it may be difficult to determine where the vehicle has a problem. Therefore, when encountering these symptoms, it is likely that there is a problem with your air dryer.

Precautions for truck dryer:

When assembling or replacing, pay attention to the connection between the air inlet and the air outlet. If it is installed in reverse, the dryer will not work. Attention should also be paid to the cleanliness of the pipeline, otherwise impurities will cause air leakage.

After the dryer is used for a long time, the drying cylinder will lose its drying effect, so it is recommended to replace the air dryer cylinder every year or every 100000 miles.

If the dryer exhausts frequently, there may be sundries in the sealing part of the one-way valve, or there may be air leakage in the pipeline behind the one-way valve of the dryer. Clean the check valve and check the pipeline behind the dryer to find the leak and seal it.

Summary:

The truck dryer is small in size, multiple functions, convenient to replace, stable and reliable in performance, and strong in load capacity. It is currently an auto part commonly used in air brake systems. However, it is necessary to pay attention to daily inspection and maintenance during use to ensure its Good effect.
