Stainless steel water ring vacuum pump (More information http://www.zbjzzk.com) used in petroleum, chemicals, machinery, mining, light industry, medicine and food, and many other industrial sectors, should be widely in many processes in industrial production . 1, when the impeller rotating in the clockwise direction indicated, water is thrown around by the impeller, due to centrifugal force, the water forms a closed ring shape is determined by the pump chamber approximately equal thickness; 2, the water of the ring part of the inner surface of the impeller hub exactly tangent, just touching the surface of the blade tip and ring in the lower part of the water, in fact, the blades have a certain ring insertion depth in the water; 3, this time to form a crescent between the impeller hub and the water ring space, and the space has been divided into a number of impeller blades equal number of small cavities; 4, if the upper part of the impeller to 0 ° as a starting point, then the volume of the impeller rotating 180 ° when the small chamber from small to big, and with the end face of the suction port connected, this time the gas is inhaled, when the suction end of the small chamber and the intake port isolation; 5, when the impeller continues to rotate, the small chamber from large to small, the gas is compressed; when small the chamber communicates with the exhaust port, the gas will be discharged outside of the pump. Because stainless steel water ring vacuum pump gas is isothermal compression, it can be exhausting flammable, explosive gas, but can also dust extraction, water gas, therefore, increasing the water ring pump applications.
