Model of centrifugal compressor: the key to decoding equipment and performance
Many friends have encountered difficulties in the selection of centrifugal compressors. Different centrifugal compressor manufacturers have different centrifugal compressor models. How to choose the centrifugal compressor products that suit them? The model of centrifugal compressor is not a simple alphanumeric combination, but a “technical identification card” that condenses the core features, performance parameters and design specifications of the equipment. Accurate interpretation of the model is very important for equipment selection, procurement, installation and maintenance.
Model of centrifugal compressor: the key to decoding equipment and performance
I. Model Rules
Usually, the model of centrifugal compressor is composed of a series of letters and numbers. The letter part is like a concise logo, which represents the key features of the manufacturer’s unique serial code and the structure of the compressor. Common model classification:
-Single-stage model: for example, Turbo-Tech’s single-stage high-speed centrifugal fan, whose principle is to accelerate the gas with a high-speed rotating impeller, and then decelerate it to convert kinetic energy into potential energy (pressure).
Turbo-Tech CF series single-stage high-speed centrifugal fans are widely used in sewage treatment, power plant desulfurization, metallurgical blast furnace blowing, oxygen supply by fermentation, chemical desulfurization, pneumatic conveying, food processing, textile and chemical fiber and other industries.
Turbo-Tech RF series process fans and circulating fans are widely used for circulating pressurization of process gas.
-Multi-stage model: A large gear drives several pinion shafts in a gear box, and one stage impeller is installed at one end or both ends of each shaft, and the impellers axially intake air and radially discharge it, and all stages of impellers are connected through pipelines, so that they can display their talents in large-scale industrial scenes and meet their strict requirements for high-pressure and large-flow gas, such as Turbo-Tech Ti series, Mn series and Ra series.
Second, the selection points
The main performance parameters of centrifugal compressor are structure, exhaust flow, exhaust pressure, suction pressure, shaft power, efficiency and speed.
1. Matching of flow and pressure demand
First of all, it is necessary to accurately evaluate the gas flow and outlet pressure required by the process flow. Too large or too small a compressor will lead to low efficiency or fail to meet the production requirements.
2. Consider the characteristics of the medium
Different compression media are like partners with different personalities, which have unique requirements for the material, sealing and cooling system of the compressor.
3. Energy efficiency and operating cost considerations
Energy efficiency is a key index to measure the compressor economy. At the same time, it is necessary to comprehensively consider the maintenance cost, including the frequency of parts replacement, maintenance difficulty and other factors.
The above is an introduction to “centrifugal compressor model: the key to decoding equipment and performance”. There are various types of centrifugal compressors, each of which contains unique value and application potential. Correctly understanding and selecting the appropriate model is of great significance for improving the efficiency, cost control and sustainable development of industrial production.
