Structural characteristics and technical advantages of centrifugal compressor

What are the structural characteristics and technical advantages of centrifugal compressor? As the key equipment in modern industrial field, centrifugal compressor plays an important role in high pressure and large flow application scenarios due to its unique working principle and structural design. The structural features of centrifugal compressor revolve around the three cores of “high efficiency, stability and adaptability”. From the power output of impeller to the pressure conversion of diffuser and volute, to the optimization of modularization and sealing system, every design aims to improve compression efficiency. It is the synergy of these structural advantages that makes it occupy an irreplaceable position in the field of industrial power.

Structural characteristics and technical advantages of centrifugal compressor

I. Analysis of Core Components

Impeller: As the heart of the compressor, the impeller generates centrifugal force through high-speed rotation, and converts gas kinetic energy into pressure energy. Most materials are corrosion-resistant titanium alloy or stainless steel to ensure long-term stability.

Diffuser: located at the outlet of impeller, it converts kinetic energy into static pressure energy by decelerating airflow. Multi-design such as tunnel and vane can optimize the airflow path and reduce the friction loss, but the deceleration process is easy to cause stall risk and needs precise control.

Rotor and stator system: the rotor includes main shaft, balance disc and other components, which support rotating parts and transmit torque; The stator is composed of cylinder and diaphragm, which cooperate with sealing elements to realize high gas compression and leakage protection.

Second, the structural design characteristics

Multi-stage series design: connecting all stages of impellers through bends and refluxers, increasing the gas pressure step by step, meeting the demand of high compression ratio, and realizing the efficiency optimization of near isothermal compression.

Modularity and compactness: the design without reciprocating parts greatly reduces vibration and simplifies basic requirements; The overall structure is lightweight, and the occupied space is significantly smaller than that of the traditional compressor, which is convenient for industrial field deployment.

Surge protection mechanism: when the flow rate drops to the critical point, the diffuser or impeller is easy to stall and lead to periodic countercurrent. By intelligently adjusting the width of the inlet guide vane or diffuser, the operation interval can be stabilized and the surge phenomenon can be avoided.
Third, technical advantages

High efficiency and energy saving: continuous rotary working mode improves the processing capacity of engineering quality.

Low maintenance requirements: few worn parts, excellent dynamic balance characteristics, reducing failure rate and maintenance cost;

Oil-free design: further eliminate the risk of lubricating oil pollution.

The above is the introduction of “the structural characteristics and technical advantages of centrifugal compressor”. With its high efficiency and reliability, centrifugal compressor is widely used in metallurgy, chemical industry and other fields, and continuously promotes the energy efficiency upgrade of industrial production.
