Features of Centrifugal Compressors
Integrated unit design
Integrated overall layout, compact structure, reasonable and simple installation, only the air pipe, water pipe and electrical system need to be connected.
Horizontal split type structure
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.
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.
Efficient backward curved impeller and integral milling diffuser
Efficient three-way flow backward curved impeller 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, it has corrosion resistance, high strength and small air resistance. The efficiency of the compressor is further improved.
Tilting bearing
The advanced five piece tilting pad bearing, which has the auto-center function ensures the best stable operation state, excellent buffer performance, good anti oil film oscillation performance, and the service life is more than 100000 hours. And the designed 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.
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.
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.
Anti surge function
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.
