When I let off brake pedal the alarm of air park brake sounds loudly. An air brake or, more formally, a compressed air brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to apply the pressure to the brake pad needed to stop the vehicle. Air-break switches at currents of 110 kV and higher (up to 750 kV) are manufactured with air-filled isolating switches. The valve (10) closes and prevents the compressed air from discharging into the atmosphere. Frictional forces slow the wheels and the vehicle comes to a stop. Usage: Air Brake switches are three phases gang operated type and use in outdoor only. When the brakes are released, the air in the brake chambers is able to be quickly rel eased and enable the vehicle to drive away. C $14.99. Lowest price in 30 days. Quick links. When the contacts (7) and (8) open, an arc is formed; it is extinguished by the stream of compressed air being directed from the chamber (5) through the outlets (nozzles) of the contacts (7) and (8) to the gas-escape channels (9), which vent to the atmosphere. The air-break switch has both the blade and the contact furnished with arcing horns. After a short time delay, the compressed air enters the cylinder of the pneumatic actuator (10) and, actuating the piston (11), breaks the contacts (12) and (13) of the isolating switch after the arc has already been extinguished. At the same time, the valve (10) opens and the compressed air leaves the reservoir (11) and passes through the nozzles (9) and the gas-escape channel (12). Air is everywhere.
