Is it better to have oil or no oil in the air compressor

Of course, it is good to be oil-free. It is clearly arranged for you from the price. Oil-free is several times the price of oil (not the kind of small piston air compressor).

The compressed air produced by the oil air compressor is with a small amount of oil, and it must be filtered, and it is still endless. No oil as long as the water on the line (oil also want to remove water). In industries such as food, medical and high-end electronics, the use of oil-free air compressors is a must, and every impurity is extremely irresponsible for the product.

Oil-free air compressors have the following advantages over air compressors:

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

The balance of the air compressor is good, so there is no need for a foundation.

3, the vibration is slight.

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

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

6, easy maintenance, because the air compressor parts are small and light, the customer's own personnel can maintain the compressor.

7. Because the drive system is maintenance-free without contact, there is no need to use expensive piston rod stuffing box. The air compressor is permanently kept completely airtight. The core of the oil-free air compressor is the outstanding two-stage compression host. The rotor is finished in twenty processes to achieve unparalleled accuracy and durability of the rotor line. The interior is equipped with high-quality bearings and precision gears to ensure the coaxiality of the rotor and make the rotor fit accurately, thereby maintaining long-term, efficient and reliable operation.

Working principle overview:

the oil-free air compressor is a miniature reciprocating piston compressor. The motor is driven by a single shaft and symmetrically distributed crank and rocker mechanical structure. The main movement is the piston ring, and the auxiliary movement is the aluminum alloy cylindrical surface. The piston ring is self-lubricating without adding any lubricant.

The compressor causes the volume of the cylindrical cylinder to change periodically through the reciprocating motion of the crank rocker, and the cylinder volume changes in opposite directions twice a week after the motor runs. 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 air enters the cylinder through the air-facing valve. At this time, it is the suction process: when the opposite direction is the volume reduction direction, the gas entering the cylinder Under compression, the pressure in the volume increases rapidly. When it is greater than the atmospheric pressure, the exhaust valve is opened. At this time, the exhaust process.

The structural arrangement of the 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 be well resolved, and the overall structure is more compact.
