Abstract: The present invention relates to a reactive turbine apparatus that is easy to assemble. To this end, the reactive turbine apparatus includes: a rotation shaft formed of a certain length; a housing defining an inner space so as to be rotatably coupled to the rotation shaft, having an inlet formed through one side thereof through which working fluid can enter, and having an outlet formed through the other side thereof so that working fluid can be discharged to the outside; and at least one rotation unit disposed in the housing and coupled to the rotation shaft, disposed in a lengthwise direction of the rotation shaft, and rotating the rotation shaft by means of the working fluid that enters from the inlet of the housing and is discharged, wherein working fluid is prevented from leaking between the peripheral surface of the at least one rotation unit and the inner surface of the housing during the rotation of the rotation unit.

Abstract: A reaction-type turbine according to the present invention is configured in that a portion of a rotary shaft module which penetrates through a side with an inlet portion of a housing has a diameter larger than the diameters of other portions. Thus, the pressurized area in which a working fluid applies pressure to a rotary shaft in the direction opposite to the working fluid flow direction increases, thus increasing force in the direction opposite to the working fluid flow direction. As a result, axial direction force applied to the rotary shaft in the working fluid flow direction may be reduced. Therefore, the reaction-type turbine of the present invention has the advantages of eliminating the necessity of installing a separate thrust bearing for supporting axial force in the working fluid flow direction.

Abstract: Disclosed herein is a nozzle rotation body for a reaction-type steam turbine, the rotation body rotating by ejection of fluid from the nozzle. The rotation body includes: a disk-shaped body (210) having an shaft hole that is formed in the center thereof and coupled to a rotary shaft; a guide portion (220), projected in the vertical direction and integrally formed with the body (210) to have a guide side (GS) providing a plurality of exhaust flow paths (221) forming equal angles to each other in the helical direction around the shaft hole; a nozzle piece (230), positioned on each front end of the exhaust flow paths (221) and assembled with the body (210), to have a cross section of the same shape as the cross section of the exhaust flow paths (221) and have a narrow width section; and a fastening unit having at least one bolt (241) and at least one assembly pin (242) coupling the nozzle piece (230) and the body (210).

Abstract: According to the present invention, a reaction-type turbine includes: a housing including a housing passage between an inlet and an outlet; a turbine shaft rotatably coupled to the housing to transmit torque; and at least one nozzle assembly coupled to the turbine shaft and rotatably provided in the housing passage. The nozzle assembly includes circumferential injection holes therein for injecting a high-pressure fluid in a circumferential direction and generating torque. Accordingly, when turbines having different capacities are manufactured, common parts can be compatibly used and assembling efficiency is improved. In addition, the eccentric rotation of the turbine shaft is prevented to significantly improve the durability of the reaction-type turbine. Furthermore, since the injection holes are long, the reaction-type turbine can be miniaturized and the efficiency thereof is improved.

Abstract: The present invention relates to a reaction-type turbine. The reaction-type turbine of the present invention is configured such that a jet and rotating unit and a turbine shaft rotate by the repulsive force generated when steam spurts from the jet and rotating unit, so as to generate propulsion force. Thus, the operating stability of a steam turbine can be maintained even when condensate water is mixed with the steam, and manufacturing costs can be significantly reduced. Further, in order to reduce a loss of energy, the flow resistance of the steam is remarkably reduced or pressure leakage is prevented, thereby obtaining a low-cost and high-efficiency turbine.
