Abstract
A stator blade for reserved inter-stage test hole, is characterized in that: the stator blade of described reserved inter-stage test hole, comprises blade inlet edge, blade trailing edge, test hole, tenon; Wherein: blade inlet edge and blade trailing edge are overall structure, and bottom is connected with tenon, the side of blade inlet edge is with 3 test holes, and uniform along leaf height direction, spacing is greater than 9 millimeters, and the thickness of blade inlet edge is greater than 3 millimeters.Advantage of the present utility model: the stator blade of reserved inter-stage test hole described in the utility model, by test hole between stator blade leading edge direct process stage, improve testing sensor installation precision and installation reliability, ensure that smooth blade surface, reduce the impact on Capability of Compressor.
Description
Technical field
The utility model relates to compressor stator blade construction applications, particularly a kind of stator blade of reserved inter-stage test hole.
Background technique
Respectively arranging blade incoming flow stagnation temperature/stagnation pressure and the distribution radially of stage temperature rise ratio/level pressure ratio for obtaining gas compressor, test repacking need be carried out to stator blade.Carry out adopt of inter-stage test more at present and weld stagnation chamber in stator blade leading edge, to reach the object of installing temperature and pressure transmitter, but in this testing scheme stagnation chamber setting angle and the angular deviation of air-flow incoming flow larger, general deviation is more than 10 °, cause measuring result error very large, adopt welded structure that blade is shown rough simultaneously, larger on Capability of Compressor impact.
Model utility content
The purpose of this utility model is that spy provides a kind of stator blade of reserved inter-stage test hole in order to solve inter-stage test result deviation comparatively large and larger on Capability of Compressor impact problem.
The utility model provides a kind of stator blade of reserved inter-stage test hole, it is characterized in that: the stator blade of described reserved inter-stage test hole, comprises blade inlet edge 1, blade trailing edge 2, test hole 3, tenon 4;
Wherein: blade inlet edge 1 and blade trailing edge 2 are overall structure, and bottom is connected with tenon 4, the side of blade inlet edge 1 is with 3 test holes 3, and uniform along leaf height direction, spacing is greater than 9 millimeters, and the thickness of blade inlet edge 1 is greater than 3 millimeters.
The aperture of described test hole 3 is between 1.5 ~ 2 millimeters.As less in blade inlet edge thickness, do not reach the requirement of processing test hole, local can be carried out to blade profile and thicken optimization.Ensure that sensor setting angle, and can reliably fix, turn avoid the adverse effect of face of weld to performance.
Advantage of the present utility model:
The stator blade of reserved inter-stage test hole described in the utility model, by test hole between stator blade leading edge direct process stage, improves testing sensor installation precision and installation reliability, ensure that smooth blade surface, reduce the impact on Capability of Compressor.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is the stator blade structural representation of reserved inter-stage test hole.
