Wrecker car brake oil leakage repair

 

First, the air brake system gas storage cylinder and pipeline corrosion, high pressure air pressure high-speed circulation leads to rust and fall off, and high-speed gas will pass off the rust and high-speed through the interface of each pipeline, damage the sealing rubber ring, resulting in air leakage.

 

Second, all kinds of joints leak, a complete set of air brake system joints up to a hundred, generally use the common interface, through the thread on the interface, plus the sealing tape, only the threading and sealing of the thread Sealing, one or two tightening may not leak, but more disassembly, the sealing will be worse, the chance of air leakage will increase.

 

Then, the country six countries and six roads wrecker brake lines leak, how to quickly find the place where the air leaks?

 

In the place where the air leak is found, two methods are generally used. When the air leaks seriously, the approximate position of the air leak can be determined by hearing, and the foam water is applied to accurately locate the leaking point.

 

But the most common use of the drivers is foam water. A little bit of foamy water in a place suspected of leaking can basically determine whether it is leaking. If you find the point of leaking, you can change parts or repair it, but it is not the way to fix it every time.

 

It’s not just the air leaks in the country’s six-country road wrecker air brake system, but also the same problem with heavy trucks. The air reservoir often loses air pressure. I believe many drivers are very distressed, so what configuration can reduce air leakage? What is the chance of qi?

 

Drying tank

 

When the multi-function sweeper was first equipped with an air brake, there were not many models equipped with dry tanks, which caused the water in the brake line of the previous model to accumulate easily. The ordinary iron gas storage cylinder was very prone to rust and fell off. Corrosion can damage the seal ring.

 

With the development of technology, the air brake system on the multi-purpose washing car is also gradually optimized. Now many models are equipped with dry tanks as standard, and absorb the water vapor in the gas path as much as possible.

 

Cooling tube

 

It is well known that the air is compressed, the temperature will rise, and the water in the liquid state will evaporate into a gas, so that the water vapor can not be completely absorbed when passing through the drying tank. After reaching the gas storage cylinder, it will still become liquid after cooling, and will still be stored in the air reservoir. .

 

Therefore, a cooling pipe can be added to cool the compressed air before the compressed air enters the drying tank, and the steam is condensed into a liquid through the drying tank to remove the moisture in the compressed air to the utmost extent. This configuration is widely used in heavy trucks, but in It is used less on multi-function washing vehicles.

 

Aluminum alloy air reservoir

 

The most direct way to avoid corrosion of the gas cylinder is to replace the aluminum alloy air reservoir to prevent rust, as long as the water is discharged regularly.

 

Push-in connector

 

In the past, the utility model used an ordinary interface on the multi-function washing vehicle. The sealing tape was wound on the interface and then tightened to achieve the purpose of sealing. However, such a sealing method cannot undergo multiple disassembly, and each time it is disassembled, it is necessary to use more. The sealing tape is tightened more tightly. After several times, the sealing performance begins to deteriorate. In order to improve this defect, some multi-function washing vehicles are equipped with a quick-release interface, which can rotate in a universal direction and is equipped with two layers of sealing rings. The sealing performance is good, and the sealing can be maintained well after repeated disassembly.

 

Leakage in the pipeline is very annoying. It leads to long-term shortage of air pressure in the air reservoir. The pump runs for a long time, increases the engine load and the loss of the air pump, which brings you high fuel consumption and high maintenance costs. It also takes a considerable amount of time to do. Check the repairs. However, with the update of the model, the technology will become more and more mature, and the problem of air leakage in the air brake system can be solved accordingly.
