48-85 m³/min Centrifugal Air Compressor Turbine System Used in Oil Refining
Application Fields
Centrifugal compressors are widely used in large-scale chemical industry, oil refining, metallurgy, oxygen production, pharmaceutical and other fields because of their outstanding advantages. It plays an important role in the relevant production equipments, and is known as the "heart" of the production line.The GDC series oil-free centrifugal air compressors are uniquely designed to ensure continuous and stable operation over a wide operating range. Their efficient operating efficiency meets the gas supply requirements of various process flows, providing absolutely oil-free high-flow compression for all industries.
Value:
Energy-Saving
Designed with the most advanced aerodynamic theory and tools, personalized design for the user's application requirements,to keep the equipment working in an energy-efficient area to achieve energy savings, which can save 30-60% energy.
Stable and Reliable
The use of aviation standards processing, manufacturing, commissioning, inspection, far higher than the general mechanical standards. The impeller uses aviation grade high strength alloy material, can be used 300,000 hours (about 35 years) without maintenance, the drive system using high-efficiency energy-saving motor, stable and reliable quality, suitable for long-term stable operation in a variety of industrial environments.
Save on investment costs, cost-effective
The core technologies and processes such as design, manufacturing and assembly are all localized, and relying on the existing research platforms of top-level Universities in China and aviation military enterprises, the design and manufacturing costs are greatly reduced. Compared with foreign advanced similar products, the input cost is reduced by at least half under the same installed power, and the equipment efficiency is not lower than or even higher than foreign advanced products.
Advantages of GooDSeaA centrifugal compressor
| Item | Features of GooDSeaA | Other Vendors |
| Integrated unit design | Simple overall layout, compact structure, reasonable and simple installation, only the air pipe, water pipe and electrical system need to be connected. Bring benefits to customers, small amount of investment, save a lot of installation time and costs | Fix the unit with four corner gasket (no shock absorption function and potential safety hazard exists) |
| The main structure adopts horizontal split type | The gearbox, bearing and sealing system are all of horizontal split structure, which is convenient for maintenance. During maintenance, it is not necessary to dismantle all the air inlet and exhaust pipes, volute, etc. Compared with vertical sectioning, it can save more than 6 times of maintenance time. | Some companies adopt vertical segmentation structure |
| Inlet regulating guide vane | Equipped with imported regulating guide vane, it can save 9% energy upon the maximum inlet flow than butterfly valve. Wide adjustment range. Save a lot of operating costs. | Butterfly valve, low cost, but high energy consumption |
| Efficient backward curved impeller and integral milling diffuser | Efficient three-way flow backward curved impeller designed by aviation university team is adopted to make the compressor reach 60-105% of flow regulation range. The diffuser made of aviation aluminum material ensures no leakage and minimal internal friction. Compared with cast iron and cast aluminum, it has corrosion resistance, high strength and small air resistance. The efficiency of the compressor is further improved. Save a lot of operating costs | Some companies adopt casting diffuser |
| Tilting bearing | With the advanced five piece tilting pad bearing, it can automatically adjust to achieve the best stable operation state, excellent buffer performance, good anti oil film oscillation performance, and can automatically adjust the service life of more than 100000 hours. The design service life of the unit shall not be less than 30 years. | |
| Cooling system | GooDSeaA cooler structure adopts water flowing inside the pipe and gas flowing outside the pipe , with guide rail and roller. The drawable straight tube cooler is made of Navy copper, which has excellent corrosion resistance and is not easy to scale. | Some companies use stainless steel. Poor heat conduction efficiency, low cost, easy to oxidize and scale. It is not suitable for cleaning and maintenance. |
| Oil circuit system | Free switching parallel double oil filter effectively avoids the disadvantage that the single oil filter must be shut down to replace the filter element and extends its service life. | Single oil filter is used in some companies, so it is impossible to change the filter element without stopping the machine under emergency |
| Carbon ring sealing system without oil | Two relatively independent working systems, air circuit and oil circuit, ensure the air quality of compressor, and overcome the leakage problem of compressor through reliable labyrinth seal or carbon ring seal system. | |
| Simple Control System | Standard PLC + color LCD touch screen, with large storage function, multiple monitoring and protection functions, can display multiple information at the same time in the same picture, which is easier to operate and more stable. | Some companies use microcomputer controller, LED display single page scrolling display screen, display content is too less, operation is troublesome. |
| Anti surge function | The system consists of surge pressure sensor and motor current sensor. When the change ratio of the last stage exhaust pressure and the change ratio of the motor current is higher than the set value of surge, PLC will regard this situation as surge, and then alarming system will work and compressor will stop meanwhile discharging the air. Through the advanced method of continuously monitoring the changes of the two parameters of system pressure and current at the same time, it can avoid the misoperation of surge only by single signal judgment, and effectively prevent the occurrence of surge | |
| Vibration protection function | Goodsea centrifugal compressor is equipped with vibration measurement system in each stage of compression section, which has protection measures for each stage. And the equipment has the functions of numerical display, alarm, shutdown, etc. Ensure safe and stable operation of the whole set machine. | In order to reduce the cost, only one vibration measuring point is arranged on each shaft. The monitoring cannot be guaranteed and the accuracy is not high. |
