gas lift refers to the spontaneous blowout of the oil well when the energy provided by the formation is insufficient to lift the crude oil from the bottom of the well to the surface. in order to make oil wells continue to produce oil, it is a method of oil extraction in which natural gas (natural gas or air) is artificially forced into the bottom of the well and crude oil is ejected from the ground. gas lift is divided into continuous gas lift and intermittent gas lift. continuous gas lift is the continuous injection of high-pressure gas into the well to discharge the liquid in the wellbore. it is suitable for oil wells with strong liquid supply capacity and high output. intermittent gas lift refers to periodically injecting gas into the wellbore during the process of stopping the injection, pushing the reservoir fluid accumulated in the wellbore to the surface, thereby expelling the liquid in the wellbore. it is mainly used for oil wells with poor reservoir supply capacity and low output.

Penjana wap, juga dipanggil mesin sumber haba wap (biasanya dikenali sebagai dandang), ialah peralatan mekanikal yang menggunakan tenaga haba bahan api atau sumber tenaga lain untuk memanaskan air ke dalam air panas atau wap. Maksud asal periuk merujuk kepada bekas air yang dipanaskan di atas api, dan relau merujuk kepada tempat di mana bahan api dibakar. Dandang termasuk periuk dan relau.

Menurut prinsip penjerapan ayunan tekanan, penggunaan ayak molekul zeolit ​​sebagai penjerap, kerana ciri-ciri penapis molekul zeolit ​​penjerapan terpilih, penjerapan nitrogen oleh ayak molekul zeolit, oksigen diperkaya dalam fasa gas, di bawah tindakan penjerapan ayunan tekanan. , pemisahan oksigen dan nitrogen. Sistem ini menggunakan dua proses menara penjerapan, satu pengeluaran oksigen penjerapan menara, satu penjanaan semula desorpsi menara, melalui PLC kawalan program pintar pneumatik Injap tempat duduk Sudut membuka dan menutup, supaya kedua-dua menara kitaran secara bergantian, output berterusan oksigen berkualiti tinggi.
