There are four major problems that Zhigao screw air compressor can solve with oil injection. Many customers have insufficient understanding of Zhigao screw air compressor. Today, we will talk about the lubrication function of Zhigao screw air compressor related performance: in a dry screw air compressor, the two rotors do not contact each other and rely on high-precision synchronous gears to maintain clearance. In oil injection compressors, due to the presence of a large amount of oil and the fact that the female rotor only absorbs a small portion of the total compression power, the synchronous gear can be eliminated, allowing the male rotor to directly drive the female rotor< Br/>

The oil injection of Zhigao screw air compressor can mainly solve the four major problems of cooling, lubrication, sealing, and noise reduction< Br/>


(1) Cooling effect: The injected oil is in the form of tiny droplets, mixed with the compressed gas, and the great heat exchange surface quickly absorbs the compression heat of the gas, cooling the compressed medium and greatly reducing the exhaust temperature< Br/>


(2) Lubrication effect: In a dry screw air compressor, the two rotors do not contact each other and rely on high-precision synchronous gears to maintain clearance. In oil injection compressors, due to the presence of a large amount of oil and the fact that the female rotor only absorbs a small portion of the total compression power, the synchronous gear can be eliminated, allowing the male rotor to directly drive the female rotor. In addition, since the injected oil is exactly the same as the lubricating oil used in the bearings, there is no longer a need for a complex sealing device to separate the gas from the lubricating oil. This allows for a smaller distance between the rotor support bearings, significantly improving the stiffness of the rotor and reducing deformation< Br/>

(3) Sealing effect: There are multiple leakage channels inside the Zhigao screw air compressor, all of which are narrow gaps. The presence of oil greatly enhances the sealing effect, reducing the amount of leakage through them< Br/>


(4) Noise reduction effect: The injected oil is a viscous fluid that absorbs and damps sound energy and sound waves. Generally, the noise can be reduced by 10-20 decibels after fuel injection.
