Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a mobile oil-free screw air compressor. Background Art

[0002] The core of the oil-free screw air compressor is the outstanding two-stage compression main engine. The rotor has undergone twenty processes of fine processing to make the rotor line shape achieve unparalleled accuracy and durability. High-quality bearings and precision gears are installed inside to ensure the coaxiality of the rotor, so that the rotor fits accurately, thereby maintaining long-term, efficient and reliable operation. The oil-free screw air compressor is a micro reciprocating piston compressor with a single-axis motor drive and a symmetrically distributed crank rocker mechanical structure. The main moving pair is the piston ring, and the auxiliary moving pair is an aluminum alloy cylindrical surface. The moving pairs are self-lubricated with the piston ring without adding any lubricant.

The box is usually equipped with a door for daily inspection, maintenance and post-repair. However, due to the limited space inside the box, it is very inconvenient during maintenance, especially when performing maintenance on the two sides or the rear of the oil-free screw air compressor, there are great limitations due to the limited space, thereby reducing the practicality of the equipment.
