| (1) Reduction in discharge pressure |
| |
The actual discharge pressure (0.68MPa) should be lowered to 0.58MPa.
(required range is 0.45 to 0.5MPa ).
[Pressure reduction △0.1MPa is corresponding to △8% of fuel consumption.] |
| (2) Control of the number of compressors brought into operation & installation of receiver tank |
| |
Currently, 6 compressors are turned on and off separately at their pressure settings. The number of compressors brought into operation should be controlled in accordance with load conditions. This will reduce power consumption, and cut down the maintenance cost.
[The receiver tank will reduce the pressure fluctuation caused by load change.] |
| (3) Prevention of air leakage |
| |
The main stop valve of each unused air pipe is closed, as is the air valve of each non-operating machine.
[Generally, the air leakage is more than 10%, sometimes it reaches to 20% in factory. Total air leakage should be reduced less than 5% by proper maintenance.] |
