55kw 75hp Electric Rotary Screw Compressor Air Cooling Direct Drive

55kw 75hp Electric Air Cooling Direct Drive Screw Air Compressor

1. Product Profiles

The direct driven screw air compressor transmits electric power to the airend through a flexible coupling, it consumes almost no energy in the transmit process, so that direct driven is the most efficient transmission mode.

2. Advantages

(1).There is no intermediate drive, so there is no energy loss.

(2).Larger rotors operate at lower speeds, so it is more efficient and further reducing energy consumption.

(3).It avoids some shortcomings of belt driven air compressor, such as unbalanced force, easy to generate heat, the belt is easy to break, frequent belt change, and need to re-adjust the level of the pulley and the tension of the belt frequently.
 

(4).Due to the coaxial transmission of the flexible coupling, the force is balanced and the vibration is reduced, which increases the reliability and reduces the maintenance cost.

3. Main Parts

1) Airend 

Air end is equipped with lasted rotors with bigger diameter and low rotate speed, high –quality SKF over loading bearing and three special oil seals guarantee the high efficiency, reliability and durability.

2)PLC intelligent control system

Human-based English user interface: remote control and several compressors interconnected; running state; automatic protective alarm.

3)Automatic adjustment intake value

Adopting 0-100% inlet proportional intake valve which stable the work pressure and save energy.

4)Specific screw compressor motor
