A braking system with enormous power is actually so fragile.
Reduced braking performance, air pump leaks, and oil coming out of the air tank are all signs of problems in the air system, and one of the main culprits is a failing dryer tank.
As the name suggests, the dryer tank is used to dry the air. Its specific function is to prevent excessive moisture in a truck's air system, thereby avoiding corrosion and rust in other components. Don’t underestimate the problems caused by low-quality dryer tanks. Next, we will show you the huge losses that low-quality dryer tanks can bring to truck owners.
A car owner's vehicle experienced an ABS fault while driving, so they went to the repair shop for inspection. After removing the ABS valve, a more serious problem was discovered. What exactly was the issue? Keep reading to find out.
The ABS system is quite delicate, and no impurities or dust should enter during operation. However, on this truck, noticeable signs of rust have been observed inside the ABS valve interface.
It is speculated that the rust inside the air circuit is caused by air containing a large amount of moisture, and the rust then flows along with the air into the valve body, causing the ABS valve to stick and leading to brake failure in the vehicle.
Next, let's look at the output port of the braking air pressure. Here we can see oil stains, indicating that the air compressor is experiencing an 'oil burning' issue, and the lubricating oil of the air compressor has already entered the ABS valve along with the airflow.
In this case, cleaning and disassembling it has little significance, and the truck owner can only purchase a new ABS valve assembly at a high price for replacement and repair. The occurrence of rust and oil in the pipeline, aside from the air compressor having an oil leakage issue, is mainly due to substandard dryer tanks that fail to properly dry the air, resulting in rust in the air circuit.
Truck Home has previously disassembled low-quality drying tanks, and found that inside there is not only no oil-absorbing felt, but the drying pellets are also not secured at all, making it easy for them to turn into powder, causing secondary contamination of the air passage and damaging the valve body.
Our drying tank is equipped with a layer of oil-absorbing felt at the air inlet, which can intercept oil vapor components in the air, preventing oil contamination of the desiccant and ensuring excellent drying performance.
At the same time, industrial-grade large-particle desiccant is used, which can fully absorb moisture in the air. According to testing by WABCO, after absorbing moisture, the desiccant moves frequently inside, colliding and rubbing against each other. Ordinary desiccant will turn into powder as a result and enter the air lines, causing damage. Industrial-grade desiccant has a robust structure and does not turn into powder.
In addition, there is a layer of filter material inside the drying tank container. The double filter material design allows the drying tank to provide better drying and filtration performance.
Focus on the research and development of automotive brake systems and pneumatic brake valves to promote the development of the auto parts industry!
