Oil-free screw air compressor frequency converter to choose a good brand

The oil-free screw air compressor in the factory usually needs to run all day and consume a lot of electricity. Advanced frequency conversion technology not only helps to save energy, but also makes the operation of the air compressor simple and stable. So in the choice of oil-free screw air compressor inverter should pay attention to what?

Operating frequency

the high power range of the air compressor inverter is 60Hz to 400Hz. A low frequency converter means that the motor runs at a low speed. When the motor works at low speed, the current increases, which is not conducive to heat dissipation. Similarly, high frequency operation will also cause damage to the motor, and in severe cases, it will burn the motor.

Motor Nameplate

look at the nameplate of the motor, you can clearly see the power, current, voltage, speed, and frequency of the motor.

Torque constraints

the torque constraints include a driving torque constraint and a braking torque constraint. The drive torque constraint ensures that the air compressor inverter will not trip when the load torque increases. Braking torque constraints ensure that the motor can decelerate to rest without tripping when decelerating without braking resistance.

with the continuous progress of science and technology, the frequency conversion technology of oil-free screw air compressor is gradually popularized and improved. When choosing a frequency conversion oil-free screw air compressor, pay attention to the parameters of the frequency converter.

Oil-free air compressors are widely used in textile, energy, transportation, food, petrochemical and machinery manufacturing industries. With the development of the current industry, less and less oil compressors are used. As people's requirements for the environment and noise are getting higher and higher, the traditional oil noise is loud, and the compressed air is air with different oil content, but the manufacturing cost is low and the pressure is high, compared with the oil-free air compressor, the manufacturing cost is relatively high, so it is more expensive.

However, granklin oil-free air compressor adopts self-produced water-lubricated air compressor main machine, all copper wire winding, small starting current, strong power, continuous constant pressure work adopts imported SKF double row automatic self-aligning bearing, which can bear high radial load, optimized contact profile of roller and raceway, and optimized contact design of large end face of roller and large gear and side guide face, effectively eliminating edge stress, and can more effectively reduce bearing temperature rise, it is better than ordinary oil-free air compressor, and the price difference is not very big.
