Daily maintenance of nitrogen making machine

For the existence of hydrogen is not easy to be detected by the senses, the ignition energy of hydrogen is very small, and the explosion energy is very high, so we must pay attention to the use and storage. 1, the hydrogen oxygen content of the input system must not exceed 0.5%. 2. When the hydrogen system is running, it is not allowed to knock. No pressure can be repaired and fastened, no overpressure is allowed and negative pressure is strictly forbidden.
