Two stage compression screw machine: comps compressor discussion on the differences between two-stage compression screw machine and single-stage compression screw machine
Two stage compression screw machine and single-stage compression screw machine are often seen in production. Here, comps compressor will introduce the differences in specific functions of the two.
Force balance
The radial and axial gas force borne by the screw of the single screw air compressor can be automatically balanced, and the star gear tooth bears the gas force, which requires the star gear tooth to have sufficient strength and stiffness; The screw rotor of twin-screw air compressor bears large radial and axial gas forces, and the screw is required to have sufficient strength and stiffness.
Manufacturing cost
Single screw air compressor screw and star wheel bearings can be ordinary bearings, with low manufacturing cost; Due to the large load of the two screw rotors, the bearing with high precision is required for the twin screw air compressor, and the manufacturing cost is high.
reliability
The star wheel of the single screw air compressor is a vulnerable part. In addition to the high requirements on the star wheel material, the star wheel also needs to be replaced regularly. There are no wearing parts in the twin-screw air compressor, and the trouble free operation time can reach 40000-80000 H.
efficiency
With the increase of running time, the wear of the star wheel of the single screw air compressor will lead to the reduction of air volume and efficiency.
Noise and vibration
The noise and vibration of single screw air compressor and twin screw air compressor are basically the same.
Processing equipment
The single screw air compressor has no mature special processing equipment, which leads to the unstable performance of the product. The twin-screw air compressor has mature screw special milling machine and grinder, which can ensure stable product performance.
Operation and maintenance
The daily operation and maintenance of single screw air compressor and twin screw air compressor are basically the same.
Applicability
Single screw air compressor is suitable for high exhaust pressure. Due to the limitations of rotor stiffness and bearing load, the twin-screw air compressor can only be used in the medium and low pressure range, and the exhaust pressure generally cannot exceed 4.5MPa.
