Description

Technical field: [0001] The invention belongs to the technical field of compressor equipment, and relates to an energy state conversion device, in particular to a dynamic balance internal combustion air compressor for converting heat energy into air pressure energy for the purpose of improving dynamic balance performance. Background technique: [0002] The high-pressure air source required by the pneumatic machinery in the field is usually provided by the piston air compressor driven by the internal combustion engine through the conveyor belt. A series of problems such as poor energy saving and environmental protection effect. In addition, due to the addition of a belt drive in the traditional internal combustion engine-driven piston air compressor system, the energy conversion efficiency is reduced. Through novelty checks, there have been relevant literature reports on internal combustion air compressors with similar dynamic balance structures, such as: [1] Zhang Jizhong, ...

Conceptual Design of Internal Combustion Compressor [J], Modern Manufacturing Engineering, 2005, (12): 90~92; etc., the "internal combustion compressor" involved in the above literature Or "internal combustion compressor" uses a connecting rod to connect the power piston and the compressor piston into a whole, and reciprocates together to realize the suction and exhaust actions. Its structure and working principle basically belong to conventional technology. The above-mentioned The "internal combustion compressor" or "internal combustion air compressor" involved in the literature does not involve and effectively solve the dynamic balance problem; therefore, it is very valuable to seek to design and prepare an internal combustion air compressor with a new structure and principle. This kind of compressor has good dynamic balance performance, realizes the integration of internal combustion engine and air compressor, and adopts two groups of crank-link mechanisms arranged symmetrically to convert the reciprocating movement of the power piston into the reciprocating movement of the compressor piston, effectively solving the dynamic balance problem , eliminate the disadvantages of large vibration and noise of the traditional internal combustion engine driven piston air compressor system, reduce weight, save space, and improve energy conversion efficiency. As a power source for wind machinery in field operations, it has great application prospects and social and economic value.
