Used compressor air system security requirements: (1) gas pipeline system should be smooth, without leakage. (2) To install the safety valve. Safety valve should open and close sensitive and reliable. When the discharge pressure exceeds the rating of 10% to 15%, should be able to automatically open; rating dropped to 95 percent, you should be able to automatically shut down. Safety valve should be tight, if the leak should stop in time, relief repair. The provisions of the safety valve shall be specified in the periodic testing. (3) the pressure gauges. One, two cylinder exhaust pipe on the road should be located gauge; pressure gauge should avoid the affected heat and vibration; pressure gauge should be intact, sensitive and accurate used large air compressor, generally used in precision 2.5. Pressure gauge should be checked every six months by qualified gauges should check seals and verification certificate. Pressure gauge range is 1.5 to 3 times the rated working pressure used large air compressor manufacturers, dial diameter not less than 100mm, the scale should be clearly visible.
