Product Structure


Working Principle

A permanent magnet frequency conversion air compressor adopts a pressure sensor to instantly sense the actual use pressure and air consumption in the system, and through the precise control of electric and frequency converter, it changes the motor speed without changing the torque of the air compressor motor, so as to regulate the system pressure in order to realize the output of compressed air according to the demand. When the system air consumption decreases, the amount of compressed air provided by the compressor is larger than the system air consumption, the inverter air compressor reduces the rotational speed, thus decreasing the amount of compressed air output; on the contrary, it raises the motor rotational speed to increase the amount of compressed air in order to maintain a stable system pressure.

Adopting vector control technology, the unit can operate at a wide range of speeds, and at the same time ensure that the motor temperature rise is minimized to get the appropriate and sufficient torque to drive the air compressor smoothly. The motor current consists of the torque component generated by the motor and other vector control technology distributes the current values of the motor to determine the values of the motor current component that generates torque and other current components. Vector control techniques can optimally compensate for this by responding to a voltage drop at the motor end, allowing the motor to output the maximum torque without increasing the current.

How is air pressure measured in air compressors?

Air pressure in air compressors is typically measured using one of two common units: pounds per square inch (PSI) or bar. Here’s a brief explanation of how air pressure is measured in air compressors:

1. Pounds per Square Inch (PSI): PSI is the most widely used unit of pressure measurement in air compressors, especially in North America. It represents the force exerted by one pound of force over an area of one square inch. Air pressure gauges on air compressors often display pressure readings in PSI, allowing users to monitor and adjust the pressure accordingly.

2. Bar: Bar is another unit of pressure commonly used in air compressors, particularly in Europe and many other parts of the world. It is a metric unit of pressure equal to 100,000 pascals (Pa). Air compressors may have pressure gauges that display readings in bar, providing an alternative measurement option for users in those regions.

To measure air pressure in an air compressor, a pressure gauge is typically installed on the compressor’s outlet or receiver tank. The gauge is designed to measure the force exerted by the compressed air and display the reading in the specified unit, such as PSI or bar.

It’s important to note that the air pressure indicated on the gauge represents the pressure at a specific point in the air compressor system, typically at the outlet or tank. The actual pressure experienced at the point of use may vary due to factors such as pressure drop in the air lines or restrictions caused by fittings and tools.

When using an air compressor, it is essential to set the pressure to the appropriate level required for the specific application. Different tools and equipment have different pressure requirements, and exceeding the recommended pressure can lead to damage or unsafe operation. Most air compressors allow users to adjust the pressure output using a pressure regulator or similar control mechanism.

Regular monitoring of the air pressure in an air compressor is crucial to ensure optimal performance, efficiency, and safe operation. By understanding the units of measurement and using pressure gauges appropriately, users can maintain the desired air pressure levels in their air compressor systems.
