ʻOi aku ka wikiwiki o ka hoʻopuehu ʻana o nā molekala Nitrogen i nā micropores o ka sieve molecular zeolite, a ʻoi aku ka mālie o ka diffusion molekala.ʻO ka laha ʻana o ka wai a me ka carbon dioxide i loko o ka ea paʻa ua like ia me ka nitrogen.ʻO ka hope, hoʻonui ʻia nā molekala oxygen mai ka hale kiaʻi adsorption.Hoʻohana ka Pressure swing adsorption oxygen production i nā hiʻohiʻona adsorption koho o ka sieve molecular zeolite, hoʻohana i ka pōʻai o ka adsorption pressurized a me ka decompression desorption, a hoʻokomo i ka ea i hoʻokomo ʻia i ka hale kiaʻi adsorption e ʻike i ka hoʻokaʻawale ʻana o ka oxygen a me ka nitrogen, i mea e hoʻomau ai i ka kiʻekiʻe. - ka maemae a me ka oxygen kiʻekiʻe.
Hoʻohana ʻo PSA oxygen generator i ka zeolite kiʻekiʻe e like me ka adsorbent e like me ke kumu o ke kaomi swing adsorption.Ma lalo o kekahi kaomi, lawe ʻia ka oxygen mai ka lewa, hoʻomaʻemaʻe ʻia a hoʻomaloʻo ʻia ka ea, a hoʻokō ʻia ka adsorption pressurized a me ka decompression desorption i ka adsorber.Ma muli o ka hopena aerodynamic, ʻoi aku ka kiʻekiʻe o ka diffusion rate o ka nitrogen i nā micropores o zeolite molecular sieve ma mua o ka oxygen.Hoʻopili maikaʻi ʻia ʻo Nitrogen e ka zeolite molecular sieve, a hoʻonui ʻia ka oxygen i ka māhele kinoea e hana i ka oxygen pau.A laila, ma hope o ka decompression i ke kaomi ea, molecular sieve desorbs i ka adsorbed nitrogen a me nā mea haumia ʻē aʻe e ʻike ai i ka hana hou ʻana.ʻO ka maʻamau, ʻelua mau hale kiaʻi adsorption i hoʻonohonoho ʻia i ka ʻōnaehana, hoʻokahi no ka adsorption a me ka hana oxygen, a ʻo kekahi no ka desorption a me ka hana hou.Mālama ka polokalamu PLC i ka wehe ʻana a me ka pani ʻana o ka valve pneumatic e hoʻokaʻawale i nā hale kiaʻi ʻelua, i mea e hoʻokō ai i ke kumu o ka hana mau ʻana o ka oxygen kiʻekiʻe.
