Tractor should pay attention to the installation of the air brake after what problems
Keep the inside and outside of the gas reservoir clean. To keep the outside of the gas storage cylinder clean, paint off the paint in time to extend its service life. Keep the inside of the gas reservoir clean to avoid residual oil and water. Every three days of operation of the tractor, it is necessary to unscrew the exclusion valve at the lower part of the air storage tank, so that the oil and water gathered in the air storage tank are removed clean, otherwise, the oil and water in the air storage tank will cause the brake failure or failure to brake; Sometimes, oil and water in the air storage cylinder will enter the brake valve and brake chamber with the brake pipeline, affecting the flow of compressed air, resulting in ineffective or unable to brake.
Maintain proper air pressure. If the brake pressure is too low, there will be braking failure, extend the braking distance, causing driving accidents; If the brake pressure is too high, because the braking is too fierce, it will not only aggravate the wear of the parts, but also cause the damage of the air pump and the air reservoir due to the excessive load of the air storage cylinder. Therefore, the appropriate air pressure must be maintained. General requirements: at the beginning, the air pressure is above 4.5 kg/cm2; In normal driving, the air pressure is not more than 7 kg/cm2. If the air pressure is more than 7 kg/cm2, you should be able to hear the release of air from the upper valve of the air storage cylinder.
The bucket brake should be slightly ahead of the main car. The trailer of a tractor and its cargo are heavy in weight and inertia. If the trailer and the main tractor brake at the same time, or even the main tractor brake ahead of the tow bucket, the strong inertia of the tow bucket and the goods will push the main tractor car, resulting in the direction of the main tractor car out of control, run off. Therefore, it should be adjusted to the trailer brake slightly ahead of the main car.
Through the adjustment of the tractor main car four wheels brake at the same time, the trailer four wheels brake at the same time. When the tractor is braking or emergency braking at high speed, if the four wheels of the main car or trailer are not braking at the same time, the tractor will suddenly run off, and it will suddenly turn to one side in serious condition, which is very easy to cause the tractor to roll over. Therefore, when the four wheels of the tractor brake is different, it should be adjusted to the four wheels of the tractor main car brake at the same time, the four wheels of the tug brake at the same time.
The brakes should be flexible and effective. In order to ensure that the tractor brake is flexible and effective, the operator should do the following three things: 1. Check whether the brake tube is connected reliably before driving out. 2. Test the brake for several times continuously to check whether the brake is flexible and effective. 3. When going down a long slope, ensure that the air pressure is sufficient. If the air pressure is insufficient, stop and pump before going down the slope until the air pressure is enough.
Brake operation method should be correct. Under normal conditions, brake, first throttle to reduce the speed, then respectively step on the clutch and brake pedal, stop smoothly, put the gear lever in neutral. In case of emergency stop, the accelerator should be closed at the same time, quickly braking a few feet, and then the "brake" "clutch" pedal at the same time, such as stopping, put the gear lever in neutral position.
About what problems should be paid attention to after the installation of the tractor air brake, agricultural resources for you to introduce this, in this remind the majority of the operators, the tractor should pay attention to the above problems after the installation of the air brake device.
