01 Features Of permanent Magnet Variable Frequency Air Compressor

It is a unique new design, which combines the permanent magnet motor and the speed control frequency converter. It couples with the high quality air end, which shows the advanced CHINAMFG technology.

1.Ultra-low temperature rise design, which allows the compressor running at ultra-low frequency for a long time.

2.Closed-loop vector control system for faster control and more precise speed control.

3.The compressor unit can still operate efficiently when the frequency is reduced by more than 50%.

4.The pressure is stable and the pressure fluctuation is accurately controlled within 0.1 bar.

5.The figure shows a comparison of several starting methods. It can be seen that the frequency converter is slowly accelerated to start, the starting is more stable, and the current CHINAMFG is completely avoided.

02 Air End

More stable, no mechanical transmission failure: high-efficiency permanent magnet synchronous motor and screw male rotor adopt embedded-integrated shaft direct connection structure, no gear transmission, completely eliminate gear pitting or broken teeth; Two independent permanent magnet motors are integrated directly drive 2 air ends, no coupling failures.

More energy efficient, the air end is always running at energy-saving speed.

More efficient and efficient permanent magnet motor + no transmission efficiency loss.

More comfortable, low running noise, eliminating 3 sources of noise: no-click bearing noise, no gear meshing noise, no coupling drive noise.

More compact: The permanent magnet motor is small in size and the integrated structure saves space.

Under the set frequency conversion pressure, the unit will automatically adjust to keep the output pressure within ± 0.1 bar, reducing unnecessary waste (the power consumption increases by 7% for every 1 bar of pressure increase)

0.3 Advantages of Permanent Magnet Motors Compared to General Asynchronous Motors

High efficiency: Eliminates excitation system losses and improves efficiency.

It is still efficient under low load conditions: the energy efficiency of a permanent magnet motor is more than 9% higher than that of a conventional asynchronous motor at full load operation, and its energy efficiency remains unchanged as the speed decreases.

Large overdrive torque: The ratio of the maximum starting torque of the permanent magnet synchronous motor to the rated torque can be more than 3 times, while the general asynchronous motor is only 1.6 times.

The control is more stable: the corresponding time of the permanent magnet motor is <50ms, and the gas production can be adjusted in a large range in an instant, so that the gas pressure is truly stable.

How do oil-lubricated and oil-free air compressors differ?

Oil-lubricated and oil-free air compressors differ in terms of their lubrication systems and the presence of oil in their operation. Here are the key differences:

Oil-Lubricated Air Compressors:

1. Lubrication: Oil-lubricated air compressors use oil for lubricating the moving parts, such as pistons, cylinders, and bearings. The oil forms a protective film that reduces friction and wear, enhancing the compressor’s efficiency and lifespan.

2. Performance: Oil-lubricated compressors are known for their smooth and quiet operation. The oil lubrication helps reduce noise levels and vibration, resulting in a more comfortable working environment.

3. Maintenance: These compressors require regular oil changes and maintenance to ensure the proper functioning of the lubrication system. The oil filter may need replacement, and the oil level should be regularly checked and topped up.

4. Applications: Oil-lubricated compressors are commonly used in applications that demand high air quality and continuous operation, such as industrial settings, workshops, and manufacturing facilities.

Oil-Free Air Compressors:

1. Lubrication: Oil-free air compressors do not use oil for lubrication. Instead, they utilize alternative materials, such as specialized coatings, self-lubricating materials, or water-based lubricants, to reduce friction and wear.

2. Performance: Oil-free compressors generally have a higher airflow capacity, making them suitable for applications where a large volume of compressed air is required. However, they may produce slightly more noise and vibration compared to oil-lubricated compressors.

3. Maintenance: Oil-free compressors typically require less maintenance compared to oil-lubricated ones. They do not need regular oil changes or oil filter replacements. However, it is still important to perform routine maintenance tasks such as air filter cleaning or replacement.

4. Applications: Oil-free compressors are commonly used in applications where air quality is crucial, such as medical and dental facilities, laboratories, electronics manufacturing, and painting applications. They are also favored for portable and consumer-grade compressors.

When selecting between oil-lubricated and oil-free air compressors, consider the specific requirements of your application, including air quality, noise levels, maintenance needs, and expected usage.
