Medical oxygen in pressure swing adsorption (PSA) technology, to extract oxygen from the air in the new equipment and efficient medical oxygen machine, which utilizes physical zeolite molecular sieve adsorption and desorption of oxygen filling technology in the oxygen machine, in Canada When the air pressure can be nitrogen adsorption, the remaining non-absorbed oxygen is collected, after purification was turned into high-purity oxygen. Specific work process for purification of compressed air dryer, after purification, by switching the valve into the absorption tower. In the adsorption tower is molecular sieve adsorption of nitrogen, oxygen adsorption at the top of the tower after being accumulate into the oxygen tank, and then in addition to smell, dust filters and sterilizing filters that get qualified medical oxygen. The main constituent parts are: air tank, air compressor medical oxygen Which is good, cold and dry green medical oxygen, oxygen hosts, such as oxygen tanks. 4, the alarm should have a warning indicator fault test function and power recovery since the start of the function. Alarm sensor circuit breaker should be able to alarm 5, each alarm should have identified and shall comply with the provisions of Section 5.3.12 of the present specification; 6, and regional gas supply alarm alarm power supply should be set to the gas emergency backup power source alarm should have the following features: a medical liquid storage tanks should start low gas supply alarm green medical oxygen machine, oxygen machine, Hebei Ericsson Ericsson provided by Hebei Medical Engineering Limited.
