The air compressor governor controls:
Answers
When the air compressor pumps air into the air storage tanks.
How fast air is pumped into the air storage tanks.
The temperature of air pumped into the air storage tanks.
The speed of the vehicle.
The Correct Answer and Explanation is :
The correct answer is: When the air compressor pumps air into the air storage tanks.
Explanation:
An air compressor governor is a crucial component in the air braking system of commercial vehicles. Its main function is to regulate the operation of the air compressor to ensure the air pressure in the storage tanks stays within an optimal range for safe braking performance. The governor monitors the air pressure in the tanks and controls the timing of the compressor’s operation, which impacts when the compressor pumps air into the tanks.
When the pressure in the air tanks drops to a certain level due to air usage (e.g., during braking or operation of vehicle systems), the governor activates the compressor to refill the tanks. Once the pressure in the tanks reaches a pre-set level, the governor signals the compressor to stop pumping air, preventing over-pressurization. This cycle of activation and deactivation ensures a consistent and safe pressure range, typically between 100 and 125 psi, depending on the vehicle and its braking system specifications.
The air compressor governor does not directly control how fast the air is pumped, the temperature of the air, or the speed of the vehicle. It primarily ensures that the air supply is maintained within the required pressure limits to keep the vehicle’s braking system functioning correctly. If the governor fails or malfunctions, it can lead to issues like inadequate air pressure, which can compromise the braking system’s effectiveness and safety.
In summary, the air compressor governor’s main role is to control the timing of when the air compressor operates to keep the air storage tanks at the proper pressure. This is essential for ensuring that the vehicle’s air brakes remain responsive and reliable, contributing to overall vehicle safety on the road.
