Oil-free screw air compressor is divided into several kinds

With the wide application of screw air compressor and the increasing demand of the market, oil-free screw air compressor has become more and more popular in the market in recent years. There are also many customers who will ask questions about oil-free screw air compressors. Today, the editor will briefly talk to everyone about the oil-free screw air compressor can be roughly divided into several categories: water lubrication type, dry grinding type, and reciprocating type.

1. water lubricated

since the oil-free air compressor uses stainless steel and ceramic composite rotors, its dynamic bearing system is completely oil-free. And because the water spray can reduce the speed of the equipment, the volumetric efficiency of water lubrication oil-free air pressure is higher.

2. dry grinding type

when the dry grinding oil-free air compressor is in operation, its screw rotor generates gas compression through high-speed expansion, and the screw of the dry grinding oil-free air compressor is sprayed with resin objects to protect the screw from high-speed friction. Damage.

3. reciprocating

miniature reciprocating oil-free air compressor motor single-axis drive, symmetrical distribution crank rocker mechanical structure. The arrangement of the single-shaft double-cylinder structure of the reciprocating oil-free air compressor can make the air flow of the equipment double the speed of the single-cylinder in the rated range, so as to solve the vibration and noise generated by the single-cylinder compressor well.

Of course, different industries have different requirements for oil-free air compressors, and users can choose according to their own production conditions.
