AXIAL FLOW PUMP WITH HIGH PRESSURE AND HIGH SPEED DISCHARGE PERFORMANCE

摘要

An axial flow pump with high pressure and high speed discharge performance of the present invention comprises: a pipe-shaped casing, which has a pipe shape and has a curved section in the orthogonal direction from an inlet to be formed long in the axial direction from the inlet, and which has a high pressure generating unit, a spiral vortex generating unit, and a high pressure generating unit in order from the inlet by being formed as steps getting smaller in the inner diameter toward an outlet formed to have a small diameter in a neck unit; a rotation axis, which is installed in the axial direction in order to be located in the center inside the casing, and which is connected to an operating device by penetrating toward the outside in the curved section in one end; a first impeller, which is located in the high pressure generating unit and is installed in the rotation axis; multiple spiral guide flags, which are formed to protrude in the inner wall of the pipe of the spiral vortex generating unit; and a second impeller, which is installed in the rotation axis by being located in the high pressure generating unit, and which has a smaller outer diameter than the outer diameter of the first impeller. Accordingly, the axial flow pump with high pressure and high speed discharge performance minimizes the change in the amount of discharge by absorbing the large amount of fluids and can be used as an alternative to a traditional expensive fire pump by spraying fluids at high pressure and high speed from the outlet. Also, the axial flow pump can remove impurities or foreign substances contained in fluids, using a filtering member, so the axial flow pump can be prevented from being damaged. In addition, the rotation direction and speed of the first impeller and the second impeller can be controlled as required, so the discharge pressure and amount are easily variable according to a target fluid or a pumping environment.;COPYRIGHT KIPO 2014
