Controls the temperature of the air leaving the air storage tanks.
The Correct Answer and Explanation is :
The correct answer is:
Controls when the air compressor pumps air into the air storage tanks.
Explanation:
The air compressor governor is an essential component of a vehicle’s air brake system or other compressed air systems. Its primary function is to regulate the operation of the air compressor, ensuring that air is pumped into the air storage tanks at the right intervals. The governor plays a critical role in maintaining the proper air pressure in these tanks to ensure the effective operation of the braking system and other air-powered components.
Here’s a detailed breakdown of how it works:
- Regulating Air Flow:
The air compressor governor monitors the air pressure in the storage tanks. When the pressure drops below a preset threshold, the governor activates the compressor to start pumping air into the tanks. Once the pressure reaches the maximum allowed level, the governor shuts off the compressor to prevent over-pressurization. - Pressure Control:
The governor ensures that the air pressure remains within a specific range, typically between 100 and 120 psi in most vehicles. This is crucial for maintaining the efficiency and safety of the air brake system, as adequate air pressure is necessary for the system to function effectively. - Preventing Overloading:
By controlling when the compressor operates, the governor prevents the system from becoming over-pressurized, which could cause damage to the compressor, air tanks, and related components. It helps maintain a balance between air supply and demand, avoiding unnecessary wear and tear. - Types of Governors:
There are two main types of governors: cut-in and cut-out. The cut-in setting determines when the governor activates the compressor, while the cut-out setting controls when the compressor shuts off.
In summary, the air compressor governor is a crucial device that ensures the proper functioning of the air compressor by controlling when it pumps air into the storage tanks based on pressure levels. It helps maintain the overall efficiency and safety of the air brake system.
