Release time：2026-08-03    Click：3

　　The core technology of a centrifugal compressor mainly includes a series of performance parameters, such as exhaust flow, exhaust pressure, specific power, compression series, surge interval, gas cleanliness, etc. This is the core yardstick to measure the energy efficiency, stability and adaptability of equipment. Turbo-Tech, a domestic high-end centrifugal compressor manufacturer, provides complete gas supply solutions with precise matching for different working conditions.

　　Core technology of centrifugal compressor: deep analysis of performance parameters and engineering application

　　First, the basic operating parameters

　　1. Exhaust flow (standard air volume)

　　Exhaust flow is the basic performance index of air compressor. Nm3/h (standard cubic meter per hour) is adopted as the measurement unit in the industry, which represents the gas production per unit time under the standard temperature and pressure environment and directly matches the peak gas demand of the factory.

　　Turbo-Tech builds a complete product matrix to cover the full flow demand;

　　Ti series small and medium-sized centrifugal air compressors have a flow range of 1200~24000Nm3/h, which is suitable for centralized gas supply in food, textile and small and medium-sized electronic factories.

The flow rate of Mn(H) series large-scale high-pressure units can reach 1200~600000Nm3/h, which can meet the working conditions of air separation, air energy storage and petrochemical plants with hundreds of thousands of cubic meters. A single machine can replace dozens of small screw units in parallel, simplifying pipeline layout and reducing operation and maintenance costs.

　　2. Exhaust pressure

　　The unit of exhaust pressure is MPa(G) gauge pressure, which represents the stable gas supply pressure at the outlet of the unit.

Turbo-TechTi series pressure covers 0.06~1.6MPa, which is suitable for most general manufacturing industries;

　　Mn(H) series has a high exhaust pressure of 16.0MPa, supports multi-stage compression structure, meets the requirements of high-pressure compression of coal chemical industry and special process gases, and has stepped pressurization and interstage cooling to suppress gas temperature rise and ensure the pressure output to be stable and fluctuation-free.

　　3. Driving motor power

　　The motor power in kW is positively related to the flow and pressure, which is an intuitive reference for the energy consumption of the unit. However, the energy saving level cannot be judged by the power value alone, and it needs to be comprehensively judged by the specific power.

　　Second, the core parameters of energy efficiency

　　Specific power refers to the electric energy consumed per cubic meter of compressed air, and the unit is kW/(m3/min), which is the decisive parameter to distinguish the energy efficiency grade of equipment and the core influencing factor of long-term operating cost of enterprises.

　　Turbo-Tech centrifugal air compressor is equipped with a wide-flow three-dimensional flow impeller independently developed, and the blade surface is optimized by CFD fluid simulation. The impeller is milled integrally with titanium alloy, which greatly improves the airflow conversion efficiency and effectively reduces the internal eddy current loss.

　　Third, the gas source quality parameters

　　For medicine, semiconductor and food industries, the cleanliness parameter of compressed air is a hard access standard.

　　1. Oil-free certification grade

　　The higher industry standard is TüVClass0 oil-free grade, which means that the oil content of compressed air is ≤0.01ppm, so as to prevent lubricating oil from polluting products. Turbo-Tech centrifugal air compressor adopts the overall separation structure of gas path and oil path, and the compression cavity has no contact with lubricating oil in the whole process, all of which have passed the TüVClass0 oil-free certification in Germany, and there is no need to install multi-stage oil removal filters, which reduces the replacement cost of consumables in the later stage and meets the strict gas source requirements for wafer manufacturing and aseptic drug production.

　　2. Atmospheric dew point

　　The primary dew point is determined by the basic exhaust temperature of the unit. Turbo-Tech multi-stage cooling design ensures that the primary exhaust temperature of the unit is stable at 60~75℃. After matching with the refrigeration/adsorption dryer, the dew point of the system can be kept below -40℃ stably, and the water content of compressed air is extremely low, thus avoiding the corrosion of pipelines of precision equipment and the short circuit of electronic components.

　　Fourthly, Turbo-Tech: Build the benchmark of domestic centrifugal compressor with the performance parameters optimized in all dimensions.

　　As a "little giant" enterprise specializing in specialty and innovation, Turbo-Tech is not limited to reaching the standard with a single parameter, but customized and adjusted the whole set of performance parameters based on different industrial working conditions, breaking the situation that high-end centrifugal equipment has long been dependent on imports:

　　1. Standardized Ti series: the flow and pressure parameters are adapted to general industries, and the modular design shortens the delivery cycle and adapts to small and medium-sized clean manufacturing;

　　2. Customized Mn(H) large-scale units: super-large flow and high-pressure parameters cover the high-end fields of energy and air separation, support multi-unit linkage intelligent regulation, and the parameters of the whole gas supply station are cooperatively matched;

　　3. Intelligent parameter management: equipped with the Internet of Things remote monitoring platform, upload all performance parameters such as flow, pressure, power, temperature and surge margin in real time, automatically generate energy efficiency reports, realize visual operation and maintenance of parameters, and facilitate enterprises to accurately control energy consumption.

　　The performance parameters of centrifugal air compressor are interrelated and mutually restricted. The selection of centrifugal air compressor is not simply to pursue large flow and high pressure, but to balance the early procurement cost and long-term operation energy consumption by combining with its own gas working conditions and comprehensively comparing the power, surge interval, air source cleanliness, vibration and noise.

　　The above is an introduction to "Core Technology of Centrifugal Compressor: Deep Analysis of Performance Parameters and Engineering Application". Based on years of research and development of fluid machinery, Turbo-Tech has achieved independent technical breakthroughs in each core performance parameter, taking into account the three core requirements of energy saving, stability and cleanliness, providing domestic centrifugal air compressor solutions with high cost performance and controllable parameters for various industries, and helping industrial production to upgrade with green and low carbon.
