Air Pressure Regulator

What is an air pressure regulator?

An air pressure regulator is the additional equipment that is mounted on an air compressor, which is the device that serves for the pneumatic driven tools or devices. As the name implies, it is used to regulate the pressure of the air that is delivered from the air compressor to the connected applications.

The air pressure regulator not only allows the operators to adjust how many amount of pressure should be given to the applications. With the constant and stable air that is produced when using the air pressure regulator, it can ensure the optimal performances of the applications.

An air compressor is used in a pneumatic driven tool or device, or serve for several devices with one unit, which mean the kinetic energy of these tools or devices are driven by the medium, the pressurized air. This device is connected to the air tank on one side and the applications on the other side with the connecting. With the air that is pumped out from the air tank, and the air compressor compresses the air, the appropriate working of the applications can be ensured.

However, using an air compressor without the air pressure regulator may cause some problems. For example, if the air that is pressurized too much, a large amount of strong air would be pushed into the tools or devices, which causes the malfunctioning of the tools or air compressor itself. In contrast, if the amount of pressure is not enough, these devices cannot work as well as the manufacturers desire.

As we realize the importance of the pressurized air that is given from an air compressor, we must not ignore the equally significant role of the air pressure regulator as well. With an air pressure regulator, not only the tools and devices can have the best performances during operation, but the lifespan of them is also prolonged in the long term.

How does an air pressure regulator form?

The arrangement of an air pressure regulator on an air compressor is related to the operation principle of the air compressor. Since the air compressor controls the air flow with the setscrew, which is presented as a large shaft along the entire device, and a system of springs, which is part of the regulator, is wrapped around the shaft of the setscrew.

The spring system, similar to the setscrew that controls the air flow of the connected device, assists the regulating of the air flow, but for the air compressor instead. This allows the regulator to be recognized as the source or beginning of the controlling systems.

In addition, the air pressure regulator is equipped with an internal diaphragm, which acts as a valve that opens to allow the air to flow, and closes to block the way of the airflow. It is when the diaphragm is in combination with the spring system that the regulator works as necessary.

Furthermore, there is also a pressure gauge on the outside of the regulator, which allows the operators to detect the change air pressure, in order to inform the requirement of the regulation or to supervise the effects of the regulator on the air compressor after it is initiated.

How does an air pressure regulator work?

The main principle of the operation of an air pressure regulator is to control the amount of pressurized air from the upstream to the downstream. The upstream here refers to the air compressor, where the pressurized air comes from. The downstream means the air output after the adjustment of the pressure regulator. 

This device works only when the pressure of air is within the tolerance of the regulator, and the technique that resists the excessive pressurized air back to the air tank is conducted by the spring system.

Once the spring system resists the excessive pressurized air, the left air that is managed with the springs would cause the diaphragm to open, and allow the air to flow to the downstream through the outlet.

As the amount of pressurized air in the downstream is regulated, the diaphragm would be kept opened, and the air flows constantly. Until the air compressor is shut off, the diaphragm is closed, and then the regulation stops here.

Is one air pressure regulator fit for every tool or device?

In the industrial fields, an air compressor may serve for several tools or devices. However, not every tool or device require the same amount of pressurized air. 

The indicator of the air pressure is usually presented as pounds per square inch (PSI). When the air compressor is operated, the required PSI of every connected tool or device is different. At that time, more than one air pressure regulators would be necessary. Instead, if the air compressor works for one tool or device only, there is no such problem to be concerned.
