| 摘要 |
The present invention relates to a vertical type centrifugal heating pump having strengthened bearing anti-corrosion function, capable of preventing corrosion of a bearing by blocking introduction of internal steam generated during a heating operation of a pump to the bearing installed above a driving shaft. The vertical type centrifugal heating pump having strengthened bearing anti-corrosion function comprises: a pump main body (10) in which a driving shaft (20) installed in a vertical direction is inserted and a heating disk (40) having a plurality of friction protrusions (41) formed to protrude along the circumference thereof is coupled to the driving shaft (20) at a predetermined height from a bottom surface; a driving motor (30) connected to an upper side of the driving shaft (20) to transmit power thereto; an upper cover body (50) coupled to an upper portion of the pump main body (10); a support bearing (60) supporting rotation of the driving shaft (20) within the upper cover body (50) at an upper side; a lower cover body (70) coupled to a lower portion of the pump main body (10); and a whirlpool hole (21) formed on a middle outer wall surface of the driving shaft (20) and generating wind in a radial direction when the driving shaft (20) is rotated at a high speed to thus prevent steam from moving up toward the support bearing (60). |
