The difference between single and twin screw compressors is reflected in the following 6 aspects

The difference between single and twin screw compressors is reflected in the following 6 aspects 1. Operation and maintenance The daily operation and maintenance of single screw compressor and twin screw compressor are basically the same. 2. Applicability Single screw compressor: suitable for high discharge pressure, such as high-pressure air compressor, refrigeration compressor and natural gas compressor. Twin-screw compressor: Due to the limitations of rotor stiffness and bearing load, the twin-screw compressor can only be applied to medium and low pressure ranges, such as power air compressors, refrigeration compressors and low-pressure natural gas compressors, etc. Generally cannot exceed 4.5MPa. 3. Efficiency In the new machine state, the efficiency of single screw compressors and twin screw compressors is basically the same. As the running time increases, the wear of the star wheel of the single screw compressor will lead to a reduction in air volume and efficiency. 4. Noise and vibration The noise and vibration of single screw compressor and twin screw compressor are basically the same. V. Processing equipment Single screw compressor: There is no mature special processing equipment, which leads to the product performance is not very stable. Twin-screw compressor: There are mature screw milling machines and grinders to ensure stable product performance. Sixth, power balance Single screw compressor: The radial and axial gas forces that the screw bears can be automatically balanced, and the star gear teeth bear the gas force, which requires the star gear teeth to have sufficient strength and rigidity. Twin screw compressor: The screw rotor withstands large radial and axial gas forces, requiring the screw to have sufficient strength and rigidity.
