Vehicles with air brake system will be equipped with air tank, which is the air storage device in the automobile brake system. The air tank is used to store the compressed gas pumped out by the air compressor (air pump), and is used for automobile braking, whistle and other systems.
The air inlet of the air tank is connected to the exhaust port of the air compressor through a joint and a brake hose. The oil and water are separated by the sudden expansion of the compressed air and stored at the bottom of the air tank, thus achieving the effect of oil-water and air separation.
The air tank is equipped with a safety valve to prevent failure of the pressure regulating device. The air pressure in the air tank shall not exceed 833 KPa. The safety valve is composed of valve seat, steel ball, spring seat, spring, valve body, adjusting bolt and lock nut. When the air pressure in the air tank exceeds the pre tightening tension of the safety valve spring, the compressed air will push the steel ball, the gas will be discharged through the exhaust hole, and the air pressure in the air tank will drop. The adjusting bolt can be used to adjust the air pressure value specified by the safety valve.
For the air tank with front and rear circuits, its air inlet is directly connected to the air compressor, and air outlets are respectively connected to the front and rear chambers of the double air chamber through joints and brake hoses to supply air for front and rear wheel braking.
The air inlet of each air tank is equipped with a one-way valve, which only allows the air compressor to charge the air tank, and the compressed air in the air tank cannot flow back to the air compressor to ensure the normal operation of the air compressor.
The bottom of each air tank is equipped with a drain switch to discharge oil and water in time to ensure the normal operation of the braking system.
The drainage interval of the air tank shall be in strict accordance with the provisions of the vehicle operation manual, and different models and different use stages shall be treated differently. Frequent inspection and drainage are good for the vehicle braking system.
