When the weather is very low or extremely high, it is when the brake system begins to show typical failures: no air, no brake, brake failure and no small trouble to the gang, and some also cause serious accidents.

Therefore, it is very important to make a comprehensive investigation of the vehicle pneumatic brake system at these times. After these years of improvement and upgrading, the basic structure of the domestic main truck gas brake system has not changed much, but the requirements of the ABS sensor and gas drier and other parts are getting higher and higher, and the special attention should be paid to the brake system.

Desiccator appearance inspection

It is difficult to distinguish the performance from the appearance of the dryer. Because the dryer completes a working cycle, it needs two actions of "water absorption and drainage". In addition to the selection of high quality Baotou northern Mercedes desiccator, it is necessary to check the normal work of the system, such as the serious oil pollution under the exhaust port, which indicates that the desiccator molecular sieve is seriously polluted by oil pollution, it has completely failed and does not have the function of water absorption.

Anti blow performance inspection of drier

Desiccator back blowing performance inspection, the normal work of the dryer in the pressure relief action, through the reverse blow tank or storage cylinder compressed air back blow dryer molecular sieve, discharge water. At this time, the exhaust port has "puff" sound and water gas discharge, if there is no exhaust action, we should check the North Baotou Mercedes desiccator base and the pressure limiting valve, the four circuit protection valve of the northern Benz accessories in Baotou and so on, and change it when necessary.

Intake temperature end check

The inlet temperature end can be checked by the temperature test paper. When the temperature is higher than 65 degrees, the filtration performance of the dryer decreases or even fails. In particular, some series of tractors should be equipped with spiral pipes to achieve the purpose of cooling.

When the temperature reaches this temperature, it will turn black and black, and then it will remain black. The function is to detect high temperature parts such as shaft head, gas path and so on.

How long will the drying tank be replaced?

It is believed that this is a problem that many car owners want to know. However, because the working conditions of each car are different, and the life of the different manufacturers is different, it is difficult to give a unified standard on the replacement cycle.

However, today we will teach you a little trick, so that you can always know whether your drying pot should be replaced.

First of all, from the appearance of the bottom of it has appeared to a certain degree of oil leakage, indicating that the internal desiccant has long been invalid, can not fully absorb water, so that the truck gas in the air becomes larger, condensate water.

The way to see whether the drying tank is due is to check the bottom of the gas tank to see if the bottom of the gas tank is wet or water, because the valve is located just at the bottom of the tank.

At the same time, the proportion of water is larger. If the drying tank fails, then the moisture in the gas path will accumulate to the bottom of the tank because of gravity, that is, the top of the valve.

This gas tank is very obvious oil, in addition to the use of poor quality drying tank, short life, and its often in the South wet areas of the working conditions, because the air humidity is larger than the north, so the life of the drying tank is shorter than the north.

After placing the oil stains or water stains on the bottom of the gas tank, replace the new drying tank. In the daily use, develop a good habit of checking the valve of the gas tank. If you install a pull ring again, it is not only convenient for daily inspection, but also can turn two times from time to time, so that the seal of the valve is more uniform and avoided. The effect of leakage free.
