Variable Frequency Screw Air Compressor

Variable-frequency screw air compressor series Introduction Every omdel has a corresponding frequency conversion compressor , which controls the air flow by changing the rotational speed of motor, making the air output and electricity consumption smoothly vary synchronously with the different air flow.When the air use quantity falls, the air supply decreases and then the electricity consumption for energy conservation, for capacity ranging from 2 to 60m3/min and discharge pressure from 0.5 to 1.3MPA,There are correspoonding models available to customers with different requirements. Variable frequency air compressor have the same good quality as other models, the quality frequency converter will further better the result of energy conseservation, with the help of the PID regulator disposed in a frequency converter, it can start up smoothly, it causes little impact on the power grid and generates great low-frequency start moment of current vector control and small running current,when the air use decreases, the compressors enter the sleeping status, saving considerable energy,Moreover , digital to analog conversion is highly accurate and the integration design features few fault points Life of bare compressor Rotors are asymmetric in profile and backed up by ball bearings and roller bearings and operate at a low speed, thereby low in abrasion and maintenance and repair expenses and the bare compressor being long in service life.Helical gears can produce axial force to kill some acting force, which reduces the load of the bearing of bare compressor.
