| 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, 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 | 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. | 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. |
