Analysis of the difference between oil-free air compressor and air compressor

Compared with air compressors, oil-free air compressors have the following advantages:

1. Due to the use of small cylinders, the air compressor is light and compact.

2. The balance of the air compressor is good, so no foundation is needed.

3. The vibration is slight.

4. The small stroke volume of a single cylinder makes the pulsation of the intake and exhaust ends less than 1%, and there is no need to install a pulsation elimination device.

5. The noise value is about 70-82 decibels, no need to take additional measures.

6. Easy maintenance. Due to the small size and light weight of the air compressor components, the customer's own personnel can maintain the compressor.

7. Since the drive system is non-contact and maintenance-free, there is no need to use expensive piston rod stuffing boxes. The air compressor remains completely airtight permanently.

At the heart of the oil-free air compressor is a superior two-stage compressor. The rotor has undergone 20 processes of finishing, so that the rotor line can achieve unparalleled precision and durability. High-quality bearings and precision gears are installed inside to ensure the coaxiality of the rotor and make the rotor fit accurately, so as to maintain long-term efficient and reliable operation.

The oil-free air compressor is a miniature reciprocating piston compressor, the mechanical structure of the crank rocker is symmetrically distributed by the motor uniaxial drive, the main movement part is the piston ring, and the auxiliary movement part is the aluminum alloy cylindrical surface, and the movement part is the same as the piston ring Self-lubricating without adding any lubricant. The volume of the cylindrical cylinder changes periodically through the reciprocating motion of the crank rocker of the compressor, and the volume of the cylinder changes twice in opposite directions once the motor runs for one cycle. When the positive direction is the expansion direction of the cylinder volume, the cylinder volume is a vacuum, the atmospheric pressure is greater than the air pressure in the cylinder, and the air enters the cylinder through the air valve, which is the suction process at this time: when the reverse direction is the volume reduction direction, the gas entering the cylinder is subjected to pressure Compression, the pressure in the volume increases rapidly. When it is greater than the atmospheric pressure, the exhaust valve is opened, which is the exhaust process. The structural arrangement of single shaft and double cylinder makes the gas flow rate of the compressor twice that of the single cylinder at a certain rated speed, and makes the vibration and noise generated by the single cylinder compressor well resolved, and the overall structure is more compact.
