What kind of air compressor is better?

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

1, because of the small cylinder, the air compressor is light and compact.

2. The air compressor is well balanced and does not need a foundation.

The vibration is very slight.

4. The small stroke volume of a single cylinder makes the pulsation at the intake end and the exhaust end less than 1%, and it is unnecessary to install a pulsation elimination device.

5. The noise value is about 70-82 decibels, and no additional measures are needed.

6. Simple maintenance. Because the components of the air compressor are small and light, customers' own personnel can maintain the compressor.

7. Because the drive system is non-contact and maintenance-free, there is no need to use an expensive piston rod stuffing box. The air compressor is permanently and completely sealed.

The core of oil-free air compressor is excellent secondary compressor. After 20 processes of finishing, the rotor profile has achieved unparalleled accuracy and durability. High-quality bearings and precision gears are installed inside to ensure the coaxiality of the rotor, make the rotor fit accurately and maintain long-term efficient and reliable operation.

Overview of working principle: Oil-free air compressor is a miniature reciprocating piston compressor. Mechanical structure of crank-rocker with motor-driven uniaxial symmetry distribution. The main motion pair is a piston ring, and the auxiliary motion pair is an aluminum alloy cylindrical surface. Motion pairs are automatically lubricated by piston rings without adding any lubricant. The compressor makes the cylinder volume change periodically through the reciprocating motion of the crank rocker. When the motor runs once, the cylinder volume changes twice in opposite directions.

When the positive direction is the expansion direction of the cylinder volume, the cylinder volume is vacuum, and the atmospheric pressure is greater than that in the cylinder. Air enters the cylinder through the outlet valve, which is the inhalation process; When the reverse direction is the volume reduction direction, the gas entering the cylinder is compressed and the pressure in the volume rises rapidly; When it is greater than atmospheric pressure, the exhaust valve opens, which is the exhaust process.

The structure arrangement of single shaft and double cylinders makes the gas flow rate of the compressor twice that of the single cylinder at a certain rated speed, and the vibration and noise generated by the single cylinder compressor are well solved, and the overall structure is more compact.
