Release time：2025-09-08    Click：35

　　Centrifugal compressor is the power source for many industrial fields, and its model selection is directly related to production efficiency, energy consumption cost and operation stability. Different types of centrifugal compressors have significant differences in pressure grade, flow range and structural design. Only by accurately matching the working conditions can the equipment performance be exerted. The following Turbo-Tech will analyze the core knowledge of centrifugal compressor model, classification and selection for you.

　　Model of centrifugal compressor: classification, selection and application guide

　　First, the classification dimension of centrifugal compressor models

　　The models of centrifugal compressors usually revolve around core performance parameters and structural features, and the common classification methods mainly include the following three categories:

　　1. Classification by structural form:

　　Single-stage centrifugal compressors (such as RF series) have simple structure and convenient maintenance, and are suitable for low pressure and large flow requirements, such as sewage treatment and gas transportation.

　　Multi-stage centrifugal compressors (such as Mn(H) series) realize high-pressure output through multiple sets of impellers in series, which are mostly used for air energy storage and gas compression in petrochemical fields.

　　In addition, there are special structural models such as horizontal split type and vertical split type, which need to be selected according to media characteristics and maintenance requirements.

　　2. According to the flow parameters:

　　The flow model directly reflects the displacement per unit time, such as Turbo-Tech Ti series centrifugal compressor, with the flow range of 1200~24000Nm3/h and the pressure range of 0.06~1.6MPa(G).

　　Turbo-Tech Mn(H) series centrifugal compressors have a flow range of 1200~600000Nm3/h and a pressure range of 0.12~16.0MPa(G). This type of compressor is often used in large-scale industrial production, such as air separation, petrochemical industry, air energy storage, wind tunnel experiments and other scenes that need to stabilize large-flow gas sources.

　　3. According to the classification of compressed media:

　　-Model of air compressor: This is a "frequent visitor" in the industrial field, and they play a key role in different production scenarios to ensure the smooth production process. For example, Turbo-tech's Ti series and Mn(H) series centrifugal air compressors.

　　-Model of process gas compressor: such as Turbo-tech Ra series process gas compressor, with flow rate of 1200~600000Nm3/h；/h; The pressure is 0.25~40.0MPa(G), and Turbo-tech Ra series compression media: natural gas, olefin gas, hydrogen, carbon dioxide, carbon monoxide, chlorine gas, vinyl chloride, hydrogen chloride, nitrogen oxides, etc. At present, Turbo-tech centrifugal compressor has been widely used in petrochemical, coal chemical, natural gas, carbon dioxide capture and other industries.

　　Second, beyond the model: what else should we pay attention to in the selection?

　　Model provides important basic information, but it is by no means the whole selection. Engineers must also study the performance curve behind it to understand the changes of flow rate, pressure ratio and efficiency under different inlet pressures, temperatures and gas compositions, especially the anti-surge control characteristics. In addition, material selection, sealing form (dry gas seal, labyrinth seal), control system and after-sales service are also the key dimensions of decision-making.

　　To sum up, "Model of Centrifugal Compressor: A Guide to Classification, Selection and Application" is introduced here for you. In practical application, it is necessary to comprehensively analyze the model parameters in combination with production requirements, media characteristics and operating costs, so as to select equipment with both economy and reliability, and provide a strong guarantee for the stable operation of industrial production.
