Description

Technical Field

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

[0002] Screw air compressor is a common industrial compressed air equipment, mainly used to compress air in the atmosphere into high-pressure gas for use in factories, workshops, medical equipment, food processing and other fields. Screw air compressor compresses air through a pair of intermeshing screws. Its working principle is similar to two spiral gears that suck air from the air inlet, then gradually compress it, and finally discharge high-pressure air;

[0003] The drive modes of screw air compressors are generally diesel drive and electric drive. These drive modes are generally suitable for large air compression environments, are not easy to carry, and cannot be used in the event of a power outage. Therefore, a gasoline internal combustion engine is used to drive the screw air compressor; in order to reduce the loss of transmission power, a transmission method of direct connection of the drive shaft is generally adopted to reduce the loss. However, the direct connection of the drive shaft requires the internal combustion engine and the screw air compressor to be installed and fixed in series, so the space occupied is large, and multiple bolts are required for installation and fixation during installation and disassembly, which is more troublesome to install.
