What is the difference between permanent magnet variable frequency air compressor and power frequency?
Variable flow control:1, the power driven air compressor can only work in one exhaust, variable frequency air compressor can work in a relatively wide range of exhaust. The frequency converter is to adjust the speed of the motor in real time according to the actual gas consumption to control the exhaust.2, when the gas consumption is low, the air compressor can also automatically sleep, thus greatly reducing the loss of energy.3, the optimized control strategy can further improve the energy saving effect.
Boot without shock:1, because the inverter itself contains almost soft starter function, the starting current is 1.2 times of the rated current, and the starting frequency is usually more than 6 times of the rated current. Compared with the starting current, the starting impact is very small.2, this impact is not only for the power grid, the impact on the entire mechanical system, but also greatly reduced.
Barometric stability:1, due to the use of screw air compressor variable frequency stepless speed regulation characteristics of inverter, inverter controller or regulator through internal PID, can smoothly start; on consumption volatility is relatively large occasions, and can quickly adjust the response;2, compared with the upper and lower limit switch control of power frequency operation, the air pressure stability is improved exponentially
