Eight advantages of using frequency converter in air compressor

In recent years, China’s call for energy conservation and emission reduction has become increasingly louder, and there has been an increasing demand for energy-saving equipment. Increasing energy conservation has also become a realistic task facing the air compressor industry. The frequency conversion air compressor is an energy-saving air compressor. Its advantages are as follows:

　　Advantage 1: Set the pressure at will and maintain a constant supply pressure

　　 1. The unit will always maintain a constant pressure supply of ±0.1bar under the set pressure required;

　　2. It can satisfy the user to set the pressure arbitrarily in the range of 3～14bar, without changing gears or belts;

　　 (Note: The highest pressure value should be determined when purchasing the machine);

　　3. When the air consumption is small, the pressure remains the same and the speed is automatically reduced, so that only enough air is satisfied.

　　4. When the air consumption is large, the pressure remains unchanged and the speed is automatically compensated to ensure the air supply needs;

　　 Advantage two: remote control

　　Using advanced control, monitoring and communication systems, through the Internet, users can conveniently obtain timely technical assistance from suppliers all over the world.

　　 Advantage 3: Energy saving

　　 Compared with traditional air compressors, air compressors equipped with frequency converters can automatically adjust the operation of the air compressors according to the air consumption, which can save energy and have significant effects.

　　 Advantage 4: High efficiency and power saving

　　 1. With variable speed control technology, the compressor displacement can be perfectly combined with the user's air consumption, completely avoiding the loss of unloading power;

　　2. Under the condition of intermittent air consumption, through the zero-load effect of soft start, the current and torque peaks are avoided, so the unit can start and stop unlimited times. Really achieve 0-100% stepless speed change, and control the generation of useless work to the maximum extent;

　　3. Eliminate the extra pressure burden of 2bar, allowing the air compressor unit to directly save energy by 14%, because every 1bar reduction in working pressure can save 7% of energy loss.

　　 Advantage 5: Extend the service life of the air compressor

The frequency converter starts the air compressor from 0Hz, which can adjust the start time of the air compressor, thereby reducing the impact on some electrical or mechanical parts inside the air compressor when starting, enhancing the reliability of the system and ensuring the service life of the compressor extend.

　　 In addition, the frequency conversion control can reduce the current fluctuation when the unit starts, and this fluctuating current will affect the power consumption of the grid and other equipment. The inverter can effectively reduce the starting current peak value to the minimum.

　　 Advantage 6: More reliable

　　 1. Frequency conversion soft start avoids electrical shock and mechanical shock;

　　2. Eliminate the disadvantages of long-term high-speed operation of the unit;

　　3, no contactor, to avoid electrical contact failure;

　　4. Eliminate the 2bar higher pressure and reduce the probability of system leakage.

　　 Advantage 7: Energy saving and environmental protection, equipment in place, start immediately

Variable frequency air compressor units do not require special installation foundation. The low-speed axial fan and modern vibration isolation and noise reduction measures make the noise of the compressor very low during operation, so it is convenient for users to place on the production site. As long as the equipment is in place, the pipeline is fast Connect, it can be started immediately.

　　 Advantage 8: Reduced the noise of the air compressor

　　 After the inverter is installed, the motor speed of the compressor is obviously slowed down under the required working conditions, which significantly reduces the noise generated by the air compressor. According to on-site inspections, the current noise is 3-7 decibels lower than the original noise.
