Abstract
A kind of engine blower testpieces Middle casing flow splitter test cloth point apparatus, is characterized in that: comprise casing outer shroud, flow splitter, casing inner ring, support plate, flow splitter test block, wall static pressure testing tube; In the outer ring inner surface of casing and casing, the inside and outside surface of ring outer surface and flow splitter forms the runner of engine jointly, and casing outer shroud and casing inner ring are connected as one by support plate, and monoblock cast goes out; The flow splitter domain and casing monoblock cast go out; Local arranges that wall static pressure measuring point place designs flow splitter test block, employing screw installation embedding flow splitter test block is connected to the mode on casing, flow splitter test block part status directly processes wall static pressure instrument connection, and directly welds wall static pressure testing tube on flow splitter test block.Advantage of the present invention: solve at flow splitter narrow space, when instrument connection is densely arranged, carries out testing the problem of layouting, and the design of flow splitter test block simultaneously effectively increases the means of point layout.
Description
Technical field
The present invention relates to engine blower test field, specifically provide a kind of engine blower testpieces flow splitter that solves and test cloth point apparatus.
Background technology
During the design of testpieces Middle casing, flow splitter arranges wall static pressure instrument connection, and quantity is a lot.And flow splitter is axial, the less arrangement space of wall static pressure testing tube that makes of radial dimension is very little, 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 wall static pressure instrument connection must perpendicular to wall, if adopt flow splitter and Middle casing monoblock cast mode, then due to the dimensional interference of Middle casing inner ring and outer shroud, wall static pressure instrument connection cannot be processed; If adopt the casting of the flow splitter domain and Middle casing split connected mode, then can reduce the rigidity of Middle casing.
Summary of the invention
The object of this invention is to provide not only have high stiffness, but also the machine that can realize add and weld the mode to meet test request, spy provides a kind of engine blower testpieces Middle casing flow splitter test cloth point apparatus.
The invention provides a kind of engine blower testpieces Middle casing flow splitter test cloth point apparatus, it is characterized in that: in described engine blower testpieces Middle casing flow splitter test cloth point apparatus, engine blower testpieces Middle casing mainly comprises casing outer shroud 1, flow splitter 2, casing inner ring 3, support plate 4, flow splitter test block 5, wall static pressure testing tube 6;
The inside and outside surface of the outer ring inner surface of casing and ring outer surface in casing and flow splitter forms the runner of engine jointly, and casing outer shroud 1 and casing inner ring 3 are connected as one by support plate 4, and monoblock cast goes out; Flow splitter 2 domain and casing monoblock cast go out; Casing inner ring 3 local arranges that wall static pressure measuring point place designs flow splitter test block 5, employing screw installation embedding flow splitter test block is connected to the mode on casing, flow splitter test block 5 part status directly processes wall static pressure instrument connection, and on flow splitter test block 5, directly weld wall static pressure testing tube 6, realize measuring.
Described flow splitter test block 5 space open, machine adds, welding is not all interfered.
Advantage of the present invention:
The present invention is by the design of flow splitter test block and mounting means flexibly, and solve at flow splitter narrow space, when instrument connection is densely arranged, carry out testing the problem of layouting, the design of flow splitter test block simultaneously effectively increases the means of point layout.
