Abstract
The invention relates to a radial inlet guide vane adjuster which mainly solves the technical problem that a medium in an inlet of a worm gear machine has flow nonuniformity. The regulator comprises an inner ring, an outer ring, a side plate, a guide vane, a guiding and locating pin, a changing guide vane angle locating pin and a guide vane rotating center pin, wherein the outer ring is fixed on the inner ring through the guiding and locating pin, the changing guide vane angle locating pin is inserted in the outer ring, the guide vane rotating center pin is inserted in the inner ring and the side plate, and the guide vane and the changing guide vane angle locating pin are connected in a sliding mode; the outer ring drives the changing guide vane angle locating pin to move, and the changing guide vane angle locating pin drives the guide vane to rotate around the guide vane rotating center pin. Thus, the angle and the relative position of the guide vane are changed so as to change the geometric parameters of an inlet runner. The inner ring is fixed and is fixed with the inlet runner of a turbine rotating machine as a mechanism connector. Because the adjustability of the guide vane changes the flowing direction of the inlet medium, the flow uniformity of the inlet medium and the efficiency of the turbine rotating machine are further increased, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of radial inlet stator regulator, belong to turbine components.Be mainly used in turbo machine and rotating machinery manufacturing technology field.
Background technique
The design that existing worm gear machinery often adopts radial air inlet and radially gives vent to anger owing to the influence of its structure can not be flowed medium uniformly in the radially volute casing runner of import, has therefore reduced the flow efficiency of the inlet fluid of turbine rotating machinery.
Summary of the invention
The objective of the invention is to remedy above-mentioned the deficiencies in the prior art, and provide a kind of compact structure, the novel radial inlet stator regulator that utilization efficiency is high.For achieving the above object, the present invention adopts following technical proposals: radial inlet stator regulator, it comprises interior ring (1), outer shroud (2), side plate (3), stator (4), guide positioning pin (5), changes stator angular positioning pin (6) and stator rotating center pin (7).
Above-mentioned outer shroud (2) is fixed on the interior ring (1) by guide positioning pin (5), change stator angular positioning pin (6) and insert outer shroud (2), encircle on (1) and the side plate (3) in stator rotating center pin (7) inserts, stator (4) is slidingly connected with change stator angular positioning pin (6), drive change stator angular positioning pin (6) motion by outer shroud (2), change stator angular positioning pin (6) drive stator (4) and move around stator rotating center pin (7).Thereby change the angle and the relative position of stator (4), change the geometric parameter of inlet channel.
The present invention has solved the uniformity of import media flow preferably, and the adjustable of stator also further changes the direction of import media flow simultaneously, has also just improved the flow efficiency and the uniformity of turbine rotating machinery medium greatly, reduces cost.The present invention can be used in the narrow and small turbine rotating machinery in compact structure space, can significantly improve the operational efficiency of equipment, and operation is simple and feasible.
