Introduction:
Every model has a corresponding frequency conversion compressor, which controls the air flow by changing the rotational speed or 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 so does the electricity consumption for energy conservation. For capacity ranging from 2 to 60m3/min and discharge pressure from 0.5 to 1.3 Mpa, there are corresponding models available to customers with different requirements.
In addition to that frequency conversion air compressors have the same good quality as other ERC models, the quality frequency converter will further better the result of energy conservation. With the help of the PID regulator disposed in a frequency converter, it can start up smoothly, causes little impact on the power grid and generates great low-frequency start moment of current vertor control and small running current. When the 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 bearsings and roller bearings and operate at a low speed, thereby low in abrasion and maintenance and repair expense and the bare compressor being long in service life. Helical gears can produce aeial force to kill some acting force, which reduces the load of the bearing of bare compressor.
