There are many types of Air Compressors. According to different standards, Air Compressors can be divided into different types. Today, we will introduce a kind of Air Compressor-screw Air Compressor in detail.
A screw compressor is a rotary positive displacement compressor. Screw compressors have two intermeshing rotors with helical gears. The volume of the meshing part of the two rotors changes from large to small, thereby compressing and discharging the gas. The components in the screw Air Compressor are manufactured by new CNC grinding machines combined with in-line laser technology to ensure very accurate manufacturing tolerances. Its reliability and performance ensure that the compressor's operating costs remain extremely low over its lifetime.
According to its body, screw compressors can be divided into two categories: belt drive and direct drive. Next, we will introduce these two screw compressors in detail. We hope that after reading this article, you can make a better choice when purchasing an Air Compressor.
Direct Drive Air Compressors
In the transmission system of the Air Compressor, it can generally be divided into direct drive and belt drive. For a long time, which of the two transmission methods is better has been one of the focuses of debate in the industry. The direct drive of the screw Air Compressor means that the motor shaft drives the rotor at a variable speed through the coupling and the gearbox, which is not actually a direct drive in the true sense. Direct drive in the true sense means that the motor is directly connected to the rotor (coaxial), and the two rotate at the same speed. This is obviously very rare. So the notion that direct drive has no energy loss is wrong. Air Compressor
The direct drive type is a coupling that combines the power supply with the main unit. Worm compressors directly drive the worm to rotate, while twin-screw compressors need to add a step-up gear to increase the speed of the main rotor.
If you're looking to buy a direct drive Air Compressor, you need to know if its benefits match your needs.
The advantage of the direct drive Air Compressor is that the excellent gear transmission efficiency can reach 98%~99%. The injected lubricating oil has the functions of sealing, cooling, noise reduction and lubrication. In addition, Air Compressors have the following advantages.
Compared with the piston machine, it has fewer wearing parts and a lower failure rate.
The working curve of the screw compression is smooth, and compared with the piston machine, the vibration is small and the noise is low.
Cooling methods are generally divided into: water cooling and air cooling.
Cooling system: plate-fin structure. And it has good materials. Make sure the cooler is pressurized. It also has high heat dissipation efficiency and good corrosion resistance.
Air Filter: Heavy-duty multi-stage intake filter. The dust removal accuracy is 1um (98% is filtered out). Great workspace. The service life is relatively long.
Belt Driven Air Compressor
The belt drive type is more suitable for compressors with a power of about 22KW. It is driven by two pulleys made according to the speed ratio, and the power is driven through the belt. This type of transmission allows the use of pulleys of different diameters to vary the rotational speed of the rotor. Belt drives use tensioned (endless) belts that run over the pulleys of the two drive shafts. Belt drive compressors rely on the friction created when tensioning the belt and pulleys to transfer power from one shaft to the other. Belt rotation can be used for transmission of large distances between two shafts (working machine and power machine). Due to the elasticity of the belt, shocks are dampened; vibrations are reduced; and transmission is smooth. But it can maintain a tight gear ratio (the ratio of the speed of the driving wheel to the speed of the driven wheel). Belt drive Air Compressor
We want to help you when it comes to purchasing a belt drive Air Compressor. Therefore, we will introduce the advantages of belt drive.

The belt tension reaches the best value in each operating state.
By avoiding excessive starting tension, the life of the belt is greatly extended, while reducing the load on the motor and rotor bearings.
Always ensure proper pulley connection.
The entire belt drive system operates safely and trouble-free.
