[0003] Oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature, and then distilled to separate it into oxygen and nitrogen. In general, since it is mostly used to produce oxygen, people are accustomed to calling it an oxygen generator. Since oxygen and nitrogen have a wide range of uses, oxygen generators are also widely used in the national economy. Especially in metallurgy, chemical industry, petroleum, defense and other industries, it is used most.
