Impulse turbine and turbine device
View Patent ↗An impulse turbine of a turbine device includes a cylindrical body having an axial hole, and a blade unit arranged to surround the periphery of the body. The blade unit includes a cylindrical base arranged to surround the periphery of the body, and a plurality of unit blades radially arranged in a line along the periphery of the base. Each of the unit blades includes an outlet that discharges fluid, injected onto the unit blade, in a direction different from the fluid spray direction, but does not discharge the fluid toward the other unit blades.
1. A turbine device comprising:
a housing, a rotating shaft, a shaft support, an impulse turbine, and a fluid discharge pipe, wherein:
the housing has a space for allowing the impulse turbine to be rotated therein and includes a fluid inlet on one side of the housing and a fluid outlet on an opposite side of the housing,
the fluid outlet communicates with the fluid discharge pipe,
the rotating shaft is configured to be axially installed in and rotated about a center of the turbine device,
the shaft support is formed in a center thereof with a through-hole through which the rotating shaft passes and includes a flange portion coupled to the one side of housing,
the shaft support is formed in a front thereof with a bearing installation groove and formed in a rear thereof with a bearing accommodation space,
a front bearing for supporting a front of the rotating shaft is fitted and coupled to the bearing installation groove,
a rear bearing for supporting a rear of the rotating shaft is fitted and coupled to the bearing accommodation space, thereby supporting the rotating shaft eccentrically from the housing, and
the impulse turbine is coupled to the rotating shaft, wherein:
(1) the impulse turbine includes a cylindrical body having an axial hole and a blade unit that surrounds a periphery of the body,
(2) the blade unit includes a cylindrical base disposed to surround the periphery of the body, and a plurality of unit blades radially arranged in a line along a periphery of the base,
(3) each of the unit blades includes an outlet that discharges an injected fluid in a direction different from a fluid injection direction but does not discharge the fluid to other unit blades,
(4) each of the unit blades includes a groove portion for temporarily accommodating the injected fluid, a bottom portion forming a bottom of the groove portion, a first blocking portion forming a right wall of the groove portion, a second blocking portion forming a left wall of the groove portion, and a third blocking portion forming a front wall and an upper wall of the groove portion, and wherein the bottom portion has a part closed by the upper wall of the groove portion and a remaining part that is opened, the first blocking portion has a length shorter than the second blocking portion, and the outlet is positioned adjacent to the first blocking portion.
