DRIVING PART AND IMPELLER ONEBODY TYPE WATERJET ELECTRIC PROPULSION UNIT AND JET BOARD FOR LIFESAVING SET IN THEREOF

摘要

The present invention relates to a driving part and impeller part integrated type waterjet electric propulsion device and a lifesaving jet board comprising the same. The present invention comprises: a device housing fixated on an intake flow passage of a jet board body through a body fixing unit; a rotor housing fixated to the body fixing unit and protecting a rotor spaced from an inner diameter of the device housing; a motor housing fixated to one cross-sectional surface of the rotor housing and having a driving motor therein and power-connected with the rotor; a seal housing fixated to the other cross-sectional surface of the rotor housing and rotating and supporting a driving shaft integrated with the rotor; and an impeller fixated to an end part of the driving shaft. According to the present invention, a driving part and the impeller part are integrated in order to prevent a power loss and reduce vibration and a noise, and the present invention is capable of excluding a winding effect due to foreign substances when water is introduced to the device since a shafting is not exposed.
