Screw air compressor Presentation

The 40 hp power frequency screw air compressor adopts the German BAOSI original main engine, which has high efficiency and slow speed. The rotor adopts the third generation tooth type; it has the characteristics of quietness, energy saving, stability, high reliability and long service life. The bearings are imported from Sweden SKF bearings. The insulation life of the equipment is up to 250,000 hours. The electrical components are all imported well-known brands (such as Siemens, Schneider TE), designed according to the most difficult conditions, to adapt to various voltage fluctuations.

Screw air compressor Working Principle

In the body of the compressor, a pair of inter mesh 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.
