Oil-free piston air compressor

Oil-free piston air compressor

The oil-free air compressor is a miniature reciprocating piston compressor. The motor is driven by a single shaft with a symmetrically distributed crank and rocker mechanical structure. The main movement is a piston ring, and the auxiliary movement is an aluminum alloy cylindrical surface. The movement is the same as the piston ring. Self-lubricating without adding any lubricant. The compressor cyclically changes the volume of the cylindrical cylinder through the reciprocating motion of the crank and rocker, and the cylinder volume changes in opposite directions twice when the motor runs for a week. When the positive direction is the cylinder volume expansion direction, the cylinder volume is vacuum, the atmospheric pressure is greater than the air pressure in the cylinder, and the air enters the cylinder through the air valve. At this time, it is the suction process: when the reverse direction is the volume reduction direction, the gas entering the cylinder is affected Compression, the pressure in the volume increases rapidly. When it is greater than the atmospheric pressure, the exhaust valve is opened, and it is the exhaust process at this time. The single-axis and double-cylinder structure makes the compressor gas flow double that of the single-cylinder when the rated speed is constant, and the vibration and noise generated by the single-cylinder compressor are well resolved, and the overall structure is more compact
