Abstract
A device for arranging test points on a shunting ring of an engine fan test-piece intermediate case is characterized in that, a case external ring, a shunting ring, a case internal ring, a support plate, a shunting ring test blocks and a wall surface static pressure test pipe are included; a flow path of the engine is formed by an inner surface of the case external ring, an outer surface of the case internal ring, and an inner surface and an outer surface of the shunting ring, and the case external ring and the case internal ring are connected into one by the support plate and made by integral casting; the whole ring of the shunting ring and the case are made by integral casting; and the shunting ring test blocks are designed to be positioned at locally arranged wall surface static pressure test points, the shunting ring test blocks are connected to the case in an embedded manner by screws, wall surface static pressure test holes are directly processed as the hunting ring test blocks are in component state, and the wall surface static pressure test pipe is directly welded on the shunting ring test blocks. The utility model is advantageous in that, the problem of arranging test points under the conditions that the space of the shunting ring is small and the test holes are densely arranged is solved, and the design of the shunting ring blocks increases the method for arranging test points.
Description
Technical field
The utility model relates to engine blower test field, and a kind of solution engine blower testpieces flow splitter test cloth point apparatus is provided especially.
Background technology
When testpieces intermediary casing designs, on flow splitter, arranged the wall static pressure instrument connection, quantity is a lot.And flow splitter is axial, the less space of arranging of wall static pressure testing tube that makes of radial dimension is very little, and pore size distribution is closeer.Because flow splitter internal cavity size is little, when welding wall static pressure testing tube, welding gun is interfered, and can not weld the whole circle of the full wall static pressure test mouth of pipe.Because the wall static pressure instrument connection must if adopt flow splitter and intermediary's casing monoblock cast mode, then because the size of interior ring of intermediary's casing and outer shroud is interfered, can't be processed the wall static pressure instrument connection perpendicular to wall; If adopt the casting of the flow splitter domain and intermediary's casing split connected mode, then can reduce the rigidity of intermediary's casing.
The utility model content
The purpose of the utility model provides promptly to be had high stiffness, again can the realization machine adds and weld satisfying the mode of test request, and the spy provides a kind of engine blower testpieces intermediary casing flow splitter test cloth point apparatus.
The utility model provides a kind of engine blower testpieces intermediary casing flow splitter test cloth point apparatus; It is characterized in that: in the described engine blower testpieces intermediary casing flow splitter test cloth point apparatus, engine blower testpieces intermediary casing mainly comprises casing outer shroud 1, flow splitter 2; Ring 3 in the casing; Support plate 4, flow splitter test block 5, wall static pressure testing tube 6;
The inside and outside surface of ring outer surface and flow splitter forms the runner of engine jointly in the outer ring inner surface of casing and the casing, encircles 3 in casing outer shroud 1 and the casing and connects as one through support plate 4, and integral casting is produced; Flow splitter 2 domains and casing integral casting are produced; The local wall static pressure measuring point place that arranges designs flow splitter test block 5; Adopt screw that embedding flow splitter test block is installed and be connected to the mode on the casing; Flow splitter 2 test block part status are directly processed the wall static pressure instrument connection; And on flow splitter 2 test blocks, directly weld wall static pressure testing tube 6, realize measuring.
Described flow splitter 2 test block space open, machine adds, welds all and do not interfere.
The advantage of the utility model:
The utility model reaches mounting means flexibly through the design of flow splitter test block; Solved in the flow splitter space narrow and small; Under the densely arranged situation of instrument connection, test the problem of layouting, the design of flow splitter test block has simultaneously effectively increased the means that measuring point is arranged.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is an engine blower testpieces intermediary case structure;
Fig. 2 is a flow splitter test block structural drawing;
Fig. 3 is embodiment one synoptic diagram;
Fig. 4 is welding wall static pressure testing tube structural representation.
Embodiment
Embodiment 1
Casing flow splitter test block embodiment 1 is as shown in Figure 2 in the utility model engine intermediary.
Engine intermediary casing comprises ring 3, support plate 4, flow splitter test block 5 in casing outer shroud 1, flow splitter 2, the casing.
The local wall static pressure measuring point place that arranges adopts flow splitter test block 5.Flow splitter test block part status is directly processed the wall static pressure instrument connection, on the flow splitter test block, directly welds wall static pressure testing tube 6.Test block adopts the screw mounting means, embeds the flow splitter domain 2 and is connected on intermediary's casing.And then wall static pressure testing tube 6 drawn intermediary's casing, realize measuring.
Described flow splitter 2 test block space open, machine adds, welds all and do not interfere.
