| 20110158841 | Screw Pump with Anti-Turbulent Structure - A screw pump with anti-turbulent structure has a housing, at least two screw rotors parallelly mounted through the housing and engaging with each other, and a partition disposed around the at least two screw rotor. The partition may have at least two circular walls respectively formed around the rotors and an annular protrusion formed on an inner surface of the housing and being adjacent to and kept from contacting the at least two circular walls, and may be a panel having at least two mounting holes respectively mounted around the rotors. Fluids flowing in opposite directions are divided by the partition and do not encounter each other and do not become turbulent. Consequently, pressurizing efficiency of the screw pump is improved. | 06-30-2011 |
