Direct Driven Screw Air Compressor advantage

1,120HP 9OKW Large Air Cooler screw Compressor transmission (1:1) host

◆No intermediate drive, so there is no energy loss

◆The larger rotor runs at a lower speed, which is more efficient and further reduces energy consumption.

◆ Avoid unbalanced hands in the belt drive, easy to generate heat, easy to break, frequent belt changes, often need to re-adjust the level of the pulley and the tension of the belt

◆ 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.

 Direct Driven Screw Air Compressor Working Principle

In the body of the compressor, a pair of intermesh helical rotors are arranged in parallel, and the rotor having convex teeth outside the pitch circle is generally referred to as a male rotor or a male screw. The rotor with concave teeth in the pitch circle is called the female rotor or the female screw. Generally, the male rotor is connected with the prime mover.

The male rotor drives the last pair of bearings on the rotating rotor of the female rotor to achieve axial positioning and withstand the compressor. Axial force. Cylindrical roller bearings at both ends of the rotor position the rotor radially and withstand the radial forces in the compressor. At both ends of the compressor body, openings of a certain shape and size are respectively opened. One for inhalation, called the intake port; the other for exhaust, called the exhaust port.
