FUNCTION
AND WORKING METHOD OF A FAST FILLING STATION WITH INTEGRATED BOOSTER:
IN AUTOMATED COMPRESSOR OPERATION DURING IDLE PERIODS, I.E. DURING THE NIGHT, THE STORAGE SYSTEMS ARE FILLED. DURING DAY TIME, WHEN A LARGE NUMBER OF SMALL TANKS HAVE TO BE FILLING WITHIN A SHORT TIME, COMPRESSORS ARE SWITCHED OVER TO BOOSTER OPERATION. THIS IS EFFECTED BY SIMPLY OPERATING A HIGH PRESSURE VALVE. THE HIGH PRESSURE STAGE OF THE MULTISTAGE HIGH PRESSURE COMPRESSOR IS NOW DIRECTLY CONNECTED TO THE STORAGE SYSTEM AND THE PRE-COMPRESSED AIR FROM THE STORAGE SYSTEM FLOWS INTO THE SMALL TANKS. AS SOON AS THERE IS A PRESSURE BALANCE IN THE SYSTEM, THE HIGH PRESSURE VALVE SWITCHES OVER TO BOOSTER OPERATION AND THE LAST COMPRESSOR STAGE COMPRESSES UP TO REQUESTED FINAL PRESSURE. OPERATION OF THE SWITCH-OVER VALVE WILL BE CARRIED OUT BY ELECTRO-PNEUMATIC REMOTE CONTROL. |
