Abstract

The invention provides a direct-drive air pressure turbine, which is a mechanical device for converting the air expansion power of compressed air into shaft power. High-pressure air is sprayed to blades of a pneumatic turbine directly by a high-pressure spray nozzle, so that the turbine is driven to rotate to obtain great shaft work. The direct-drive air pressure turbine has the advantages of high energy efficiency, simple facilities, wide application range and the like, and is suitable for driving a generator to generate electricity and other devices which need the shaft work.

Description

[Affiliated technical field] [0001] The invention relates to a direct-drive air pressure turbine, which is a mechanical device for transforming gas expansion power of compressed air into shaft power. It is suitable for driving generators to generate electricity and other equipment that requires shaft work. [Background technique] [0002] Equipment driven by shaft power is very common in the field of modern engineering technology. Common internal combustion engines, electric motors, etc. all drive the machine to run by providing shaft power to the target machine. Pneumatic machinery is a device that converts gas expansion force into shaft power. Pneumatic principles are used in many pneumatic equipment. These pneumatic equipment are often integrated machines such as pneumatic cutting machines, impact drills, etc. The market lacks an independent pneumatic equipment. drive equipment. [0003] In combination with engineering needs, the present invention is based on making up f...
