Features of Centrifugal Compressors
Integrated overall layout, compact structure, reasonable and simple
installation, only the air pipe, water pipe and electrical system
need to be connected.
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.
Equipped with imported regulating guide vane, it can save 9% energy
upon the maximum inlet flow than butterfly valve. Wide adjustment
range.
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.
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.
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.
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.
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.
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.
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
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.
