Variable-frequency Screw Air Compressor Series
Capacity: 0.68~56.0 m3/min
Motor Power: 11~315kW (Horse Power: 15SA ~ 420SW)
When high-precision torque wrench fastening bolts, it can accurately control the preload force when fastening and make sure each fastener able to fasten each parts at the right preloading force status.
Description
Introduction
Every model 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 so does 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 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 ector control and small running current hen 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.
More Reliable Operation
With frequency conversion soft start reduce in-rush starting current ,reduce wear on electrical switch gears and motor windings. Also maintain less power during starting and stopping of motors and increase protection to motors. Also reduce peak demand and improve power factor.
