Difference between centrifugal air compressor and screw air compressor

Difference between centrifugal air compressor and screw air compressor？Centrifugal air compressor and screw air compressor are two widely used compressed air production devices.Each has its own unique advantages and applicable scenarios.There are significant differences between them, which depend on their working principle, performance characteristics, applicable scenarios and maintenance requirements.In this paper, Turbo-tech will take you to discuss the differences between these two kinds of air compressors, and help users make more suitable choices according to their own needs.
The difference between centrifugal air compressor and screw air compressor is mainly as follows:
1. Working principle
Centrifugal air compressor:The working principle of centrifugal air compressor is based on the process of converting kinetic energy into pressure energy.Air passes through a high-speed rotating impeller, and the rotation of the impeller makes the air gain kinetic energy, and then the kinetic energy is converted into pressure energy in the diffuser, thus realizing compression.
Screw air compressor:The screw air compressor adopts a pair of screw rotors that mesh with each other, and the air is compressed by the rotation of the rotors.
2. Performance characteristics
Efficiency: centrifugal air compressor shows higher efficiency under high flow and high pressure.Especially in large-scale industrial facilities that need a lot of compressed air.In contrast, the screw air compressor is more suitable under the conditions of small and medium flow and low pressure.
Noise level:Because there are no moving parts in the centrifugal air compressor that are in direct contact, the noise generated by them is relatively low.Although the screw air compressor also has good sound insulation measures, it may produce more mechanical noise in some cases.
Maintenance and cost:Centrifugal air compressor has relatively low failure rate and low maintenance cost because of its few moving parts.Screw air compressor has a complicated structure and needs regular maintenance.
3. Applicable scenarios
Centrifugal air compressor: Because centrifugal air compressor is an oil-free air compressor, it is suitable for those applications that have strict requirements on air purity, and because of its large flow characteristics, it is suitable for continuous operation occasions that need a lot of compressed air, such as chemical industry, textile and food processing industries.
Screw air compressor: it is widely used in various small and medium-sized enterprises and workshops, including automobile maintenance, metal processing, textile and other industries. They are also commonly used in construction sites and other temporary workplaces.
The difference between centrifugal air compressor and screw air compressor is introduced here for you. Centrifugal air compressor and screw air compressor have their own advantages and disadvantages, and which type to choose should be decided according to actual demand, budget constraints and expected operating conditions.
