Lapaʻau oxygen generator me ka puʻe kowali adsorption (PSA) enehana e like me ke kumu, e extract oxygen mai ka lewa o ka mea hou lako, ka hoʻohana 'ana i ka molecular kānana physical adsorption a me ka desorption 'enehana i loko o ka molecular sieve oxygen generator i ka hoouka ana, i ka wa o ke kaomi i ka lewa. hiki i ka nitrogen adsorption, ke koena unabsorbed oxygen ua ohi ia, e lilo ia ma hope o ka hoʻomaʻemaʻe lapaʻau o kiʻekiʻe maemae oxygen.ʻO ke kaʻina hana kikoʻī ʻo ia ka hoʻomaʻemaʻe ʻana o ka ea i hoʻomaʻemaʻe ʻia e ka mea hoʻomaʻemaʻe ea a laila komo i ka hale kiaʻi adsorption ma o ka valve hoʻololi.I loko o ka hale kiaʻi adsorption, ua hoʻopili ʻia ka nitrogen e ka molecular sieve, ua hōʻiliʻili ʻia ka oxygen ma ka piko o ka hale kiaʻi adsorption i loko o ka pahu mālama oxygen, a laila ma o ka wehe ʻana i ka ʻala, ka hoʻohemo ʻana i ka lepo a me ka kānana kānana sterilization ua kūpono ka oxygen olakino.ʻO nā mea nui: ea pahu, ea compressor, maloʻo maloʻo mīkini, oxygen host, oxygen tank a pela aku.
