Discover The Secrets Of Air Compressor Governor Controls: Find Out How They Work

Air compressors are indispensable tools in various industries and applications. They provide a reliable source of compressed air for powering pneumatic tools, operating machinery, and performing countless tasks. To ensure optimal performance and safety, air compressors are equipped with a critical component known as the governor.

Governor: The Watchdog of Air Pressure

The governor is the brain of an air compressor, responsible for maintaining a stable air pressure within the system. It acts as a gatekeeper, regulating the compressor’s operation to prevent over-pressurization and premature wear.

Types of Governor Controls

Air compressor governors come in various types, each designed for specific applications and compressor configurations. The most common types include:

1. Pressure Switch Governors

These governors use a pressure-sensitive switch to monitor the air pressure in the system. When the pressure reaches a predetermined set point, the switch activates the compressor to start filling the tank. Once the desired pressure is achieved, the switch turns off the compressor, maintaining a constant air supply.

2. Unloader Governors

Unloader governors are used in compressors with an unloading mechanism. When the air pressure reaches the desired level, the governor activates the unloader, which vents the compressed air from the compressor’s discharge line. This prevents the compressor from over-pressurizing and allows it to run unloaded until the pressure drops below the set point.

3. Load/Unload Governors

These governors combine the functions of pressure switch and unloader governors. They monitor the air pressure and activate the compressor or unloader as needed to maintain a stable pressure within the system.

4. Electronic Governors

Electronic governors utilize electronic sensors and controllers to monitor and regulate air pressure. They provide precise control and offer additional features such as digital displays, remote monitoring, and programmable settings.

Key Functions of Governor Controls

Regardless of the type, governor controls perform essential functions in air compressor operation:

1. Maintain Stable Pressure: Governors ensure that the air pressure in the system remains within a predetermined range, preventing over-pressurization and under-pressurization.
2. Prevent Over-Pressurization: They act as a safety mechanism, shutting off the compressor if the air pressure exceeds a safe limit.
3. Optimize Compressor Operation: Governors regulate the compressor’s operation to maximize efficiency and minimize wear.
4. Extend Compressor Life: By preventing over-pressurization and premature wear, governors contribute to the longevity of the air compressor.

Troubleshooting Governor Controls

Malfunctioning governor controls can lead to various issues with the air compressor. Common symptoms include:

• Fluctuating Air Pressure: Erratic pressure readings may indicate a faulty governor.
• Over-Pressurization: If the compressor continues to fill the tank beyond the set pressure, the governor may be malfunctioning.
• Compressor Not Starting: A faulty governor may prevent the compressor from starting or running properly.

If you encounter any of these issues, it’s crucial to check the governor and troubleshoot any potential problems.

The Bottom Line: Ensuring Optimal Air Compressor Performance

Governor controls play a pivotal role in the safe and efficient operation of air compressors. By understanding the different types and functions of these controls, you can ensure that your air compressor performs optimally and provides a reliable source of compressed air for your applications.
