Answers
125 psi.
100 psi.
150 psi.
80 psi.
The Correct Answer and Explanation is :
The correct answer is 125 psi.
Explanation:
An air compressor governor plays a crucial role in regulating the operation of the air compressor, ensuring it does not over-pressurize the air tanks. The governor is a vital component in systems like those used in trucks, industrial machinery, or other vehicles that rely on air compressors to power systems such as brakes, suspension, or other pneumatic devices. The governor is typically a pressure-sensitive switch that controls when the compressor engages and disengages.
In general, the air compressor governor is set to engage the compressor when the pressure in the air tank drops below a specific threshold and will stop the compressor once the desired air pressure level is reached. This pressure level is typically between 100 and 125 psi. Most commercial and heavy-duty air systems are designed with a governor that cuts out the compressor at around 125 psi, to prevent excessive pressure buildup in the tank, which could lead to damage or safety issues.
Here’s how it works:
- Air compressor cut-in: When the air pressure in the tanks drops below a certain level, usually around 100 psi, the governor activates and signals the compressor to begin pumping air into the tank.
- Air compressor cut-out: Once the air pressure reaches 125 psi, the governor shuts off the compressor to prevent over-pressurization. This prevents the risk of damaging components, maintaining the safety and longevity of the system.
Different systems may have slight variations in these settings, but in most cases, 125 psi is the standard cut-out pressure. Some systems might have a lower cut-off limit, but it’s typically no lower than 100 psi. In any case, these settings are crucial for the safe operation of air-powered systems, ensuring that the air tanks are sufficiently pressurized without reaching dangerous levels.
