technical field

The utility model relates to the field of air compressor heads, in particular to an oil-free double-cylinder low-noise air compressor head.

Background technique

The air compressor head is the head of the air compressor, and the air compressor is a device used to compress gas. Air compressors are similar in structure to water pumps. Most air compressors are reciprocating piston, rotating vane or rotating screw. Centrifugal compressors are very large applications. The compressor is directly driven by an electric motor, causing the crankshaft to generate rotational motion, which drives the connecting rod. The rod causes the piston to reciprocate, causing the cylinder volume to change. Due to the change in the pressure in the cylinder, the air enters the cylinder through the air filter through the intake valve. During the compression stroke, due to the reduction of the cylinder volume, the compressed air passes through the exhaust valve. Through the exhaust pipe, the one-way valve enters the gas storage tank. When the exhaust pressure reaches the rated pressure of 0.7MPa, it is controlled by the pressure switch and automatically stops. When the pressure of the gas storage tank drops to 0.5--0.6MPa, the pressure switch automatically The air compressor is the core equipment of the pneumatic system and the main body of the electromechanical bleed air source device. It is a device that converts the mechanical energy of the prime mover, usually an electric motor or a diesel engine, into gas pressure energy. Air pressure generator for compressed air.

The air compressor head is the head of the air compressor. For the double-cylinder air compressor head, the air compressor head will generate a lot of noise due to the compression of the air during operation, which will seriously affect the quality of the working environment, and it is not easy to effectively silence the noise. When the air compressor head is working, it is also easy to generate large noise due to vibration, which is not easy for the stable operation of the double-cylinder head, and more dust will adhere to the front end of the intake valve and the surface of the air compressor head, which affects the use.
