The Atlas Copco Xrvz 455 air compressor is a sliding screw air compressor, mainly used in the industrial sector of air compressor equipment
Atlas Copco's Xrvz 455 air compressor is a diesel air compressor. A diesel air compressor is an air compressor powered by a diesel engine
They are commonly used in places where electricity is supplied far from the grid, such as construction sites, field construction and mining. Diesel air compressors have an independent power source, so they are very suitable for environments where no power is available.
1. Stable air pressure
1. Because the variable-frequency screw air compressor takes advantage of the stepless speed regulation characteristics of the frequency converter, it can start gently through the controller or PID regulator inside the frequency converter; For the occasion of large fluctuations in gas consumption, it can quickly adjust the response.
2, compared with the upper and lower limit switch control of power frequency operation, the pressure stability is exponentially improved. Second, start without impact
1, because the frequency converter itself contains the function of the soft starter, the maximum starting current is less than 1.2 times the rated current, and the power frequency starting is generally more than 6 times the rated current compared with the starting impact is small.
2, this impact is not only on the power grid, the impact on the entire mechanical system, but also greatly reduced.
Three, variable flow control
1, the power frequency driven air compressor can only work in one displacement, frequency conversion air compressor can work in a wide range of displacement. The frequency converter adjusts the motor speed in real time according to the actual air consumption to control the air displacement.
2, when the gas consumption is low, the air compressor can also be automatically hibernated, which greatly reduces the loss of energy.
3, the optimized control strategy can further improve the energy saving effect.
Fourth, AC power supply voltage adaptability is better
1, due to the overmodulation technology used by the inverter, when the AC power supply voltage is slightly low, it can still output enough torque to drive the motor; When the voltage is slightly higher, it will not cause the output voltage to the motor to be high.
2, for the occasion of self-electricity, frequency conversion drive can show its advantages.
3. According to the characteristics of the motor VF (frequency conversion air compressor works below the rated voltage in the energy-saving state), the effect is obvious for the site of low power grid.
Five, low noise
1. Most working conditions of the frequency conversion system are lower than the rated speed, the mechanical noise and wear of the host are reduced, and the maintenance and service life are extended.
