The electronically controlled pressure regulators are used to maintain the level of air pressure in the airline equipment. The proportional pressure regulator keeps the air pressure at the minimal level the flight is going at an altitude. The electro pneumatic regulators are specially designed in the aircraft cabin pressurization and canopy seal system. Air pressure control valves are used in the altitude control system.
Key Applications in Airline Equipment:
The key applications in airline equipment are as follows:
1. Environmental Control Systems (ECS)
2. Landing Gear and Braking Systems
3. Fire Suppression Systems
4. Oxygen Systems
5. Engine Control
Maintaining the Oxygen Level:
When an airplane is taking flight at an altitude, it is facing pressure, can’t imagine. In this situation, maintaining the oxygen level at the desired level is critical for the safety of the passengers.
The electronically controlled pressure regulator is used to pressure cabins at the desired level, so the passengers don’t face the fierce pressure of the air when the airplane is taking the flight at an altitude where the air pressure is much higher than the surface air pressure.
Airplane Pressurized Cabins:
The airplane cabin is sucked into electronic pressure control, and the air is cooled and humidified with the help of the regulators. Then this air is circulated throughout the air cabins. Meaning the moisture is added to it.
There is an automatic pressure regulator installed to moisten the air inside the air cabin to provide the most comfortable environment. It may possibly be at an altitude where the flight may be facing direct radiation from the sun.
Why is Cabin Pressure Important?
Cabin pressure is crucial for the flight operation, the main reason being the difference in the density of the air. This is maintained with the help of the electronically controlled pressure regulator.
- Density of the Air: The density of the air is different from the low density. At the ground level, the density of the air is around 14 pascals per square inch(PSI). When the airplane reached the cruising height, like 30000 to 40000 feet, the density of the air was around 4 to 5 pascals per square inch. This can be difficult for the passenger to breathe adequately in such low desert air.
- Maintain Amount Of Oxygen: The less density of the air means the amount of oxygen. At this pressure, the oxygen is also at the lowest level. To counter this electronically controlled pressure regulator is used to pressurize the cabins at an adequate level.
So the passenger can breathe adequately. The less-dense air means a smaller amount of oxygen is received by the passengers.
Conclusion:
The airplanes can’t perform the air operation properly if these flights are not pressurized at an adequate level. The electronically controlled pressure regulator is used to keep the pressure of the flight cabin at 14 PSI. This pressure of the air is essential to make breathing possible for the passenger. It can be just too difficult for the passenger to breathe without this air pressure at the higher altitudes.
