Air compressor oil-free is better.
Oil-free air compressors have the following advantages over air compressors:
1. Air compressors are lightweight and compact due to the use of small cylinders.
2. The air compressor is well-balanced, thus no foundation is required.
3. Slight vibration.
4, the small stroke volume of a single cylinder makes the pulsation at the inlet end and exhaust end less than 1%, so there is no need to install pulsation elimination devices.
5. The noise level is approximately 70-82 dB, eliminating the need for additional measures.
6, easy maintenance, because the compressor components are small and lightweight, the customer's own personnel can maintain the compressor.
7, because the drive system is contactless and maintenance-free, there is no need to use expensive piston rod stuffing box. The compressor remains completely airtight permanently.
The core of the oil-free air compressor is the outstanding two-stage compression mainframe. The rotor is finely machined through twenty processes to achieve unrivaled accuracy and durability of the rotor line. High-quality bearings and precision gears are fitted inside to ensure the coaxiality of the rotor, so that the rotor fits accurately and thus maintains long-lasting, efficient and reliable operation.
Overview of the working principle: oil-free air compressor is a miniature reciprocating piston compressor, motor single-axis drive symmetrical distribution of crank rocker mechanical structure, the main movement of the pay for the piston ring, the secondary movement of the pay for the aluminum alloy cylindrical surface, the movement of the pay for the same with the self-lubrication of piston ring without adding any lubricant. Compressor through the crank rocker reciprocating motion of the cylindrical cylinder volume cyclic changes, the motor runs a week cylinder volume has two changes in the opposite direction.
When the positive direction is the direction of cylinder volume expansion, the cylinder volume for the vacuum, the atmospheric pressure is greater than the cylinder air pressure, air through the valve into the cylinder, this time for the suction process: when the opposite direction is the direction of the volume reduction, the gas into the cylinder is compressed, the pressure within the volume of the rapid increase in the pressure is greater than the atmospheric pressure, the exhaust valve is opened, this time for the exhaust process.
The single-axis double-cylinder structural arrangement of the compressor gas flow at a certain rated speed for the single-cylinder twice, and makes the single-cylinder compressor vibration noise is a good solution, the overall structure is more compact.
