New Type Vacuum Degasser is solids control equipment for treatment of gas cut drilling liquid. It can get rid of incursive gas quickly in drilling liquid to recover specific gravity of drilling liquid and stabilize its performance. It is indispensable equipment in exploratory well and drilling in ultradeep well and under-balanced drilling. It is applicable to various kinds of drilling liquid cycling purification system. This degasfier is equipped with water-ring vacuum pump and constant temperature working status. It is suitable to suck flammable and combustible gas, with safe and reliable performance.The structure of gas-water separator is reasonably designed to assure of effective separation of gas and water and free-flowing of vent pipe.
