The pressure test on site is mainly to checkAir separation equipmentAir tightness. Pay attention to the following problems when testing pressure:
1) it is strictly prohibited to use oxygen as the pressure test air source;
2) clean the oil-free pressure test air source for the equipment without degreasing after pressure test;
3) the pressure gauge used for pressure test should be checked and sealed with lead before using. Check carefully whether the pressure gauge valve has been opened before pressure test;
4) during pressure test, do not use a hammer to knock the pressure test container;
5) Do not dismantle or tighten the screws during pressure test;
6) when using nitrogen cylinder or air source with higher pressure level to inflate and test pressure to the container with lower pressure, pressure reducing valve should be installed, and direct inflating is strictly prohibited.
