Description

Modularized gas turbine inlet guide vane icing test section Technical Field The invention relates to a test device, in particular to a gas turbine test device. Background Under the conditions of low-temperature sea areas such as two poles and the like, the marine gas turbine is in a low-temperature and high-humidity working environment for a long time, which can cause the icing phenomenon of a ship power system, deteriorate the performance of pneumatic components, cause the stall or surge of a gas compressor and seriously influence the running stability and safety of the ship. In the whole gas turbine, the gas compressor inlet is the most common icing part in the gas turbine, and main icing components comprise a fairing, an inlet guide blade, a support plate, an inlet cavity and the like, so that in order to explore the icing law of the gas turbine inlet components under different sailing states, a visual icing test bed with adjustable inlet parameters needs to be built, and in addition, the equipment can be conveniently disassembled and assembled, and measurement equipment is convenient to install, replace test pieces and obtain icing data. Most of the existing icing test tables and wind tunnels are designed into a whole, and although the test purpose of obtaining icing data can be achieved, if one part of the test tables needs to be replaced, replacement test instruments and the like are added, and the whole test section can be replaced only by the aid of the existing solutions, so that time and labor are wasted. Disclosure of Invention The invention aims to provide a modularized gas turbine inlet guide vane icing test section which can solve the problems that an existing test bed is time-consuming and labor-consuming, and maintenance parts are inconvenient to replace. The purpose of the invention is realized in the following way: The invention relates to an icing test section of an inlet guide vane of a modularized gas turbine, which is characterized by comprising a test section test piece, a test section connecting piece and a test section shell, wherein the test section connecting piece comprises an outer flange disc and an inner concave stress mounting ring, both ends of the test section shell are provided with convex stress mounting rings, both ends of the test section shell are provided with the test section connecting piece, the test section shell is connected with the concave stress mounting rings through the convex stress mounting rings, and the test section test piece is arranged in the test section shell. The invention may further include: 1. The test section test piece comprises a cover plate, a chute seat and a blade, wherein a chute is arranged in the chute seat, one end of the blade is installed in the chute, a threaded hole is formed in the cover plate, the other end of the blade is connected with the cover plate through a bolt, the blade and the chute seat are located in a test section shell, and the chute seat is connected with the test section shell in a matched manner through a mortise-tenon joint structure. 2. The concave stress mounting ring is provided with a wedge-shaped groove structure, the convex stress mounting ring is provided with a wedge-shaped boss structure, and the wedge-shaped groove structure is matched with the wedge-shaped boss structure. 3. The upper part and the two sides of the test section shell are reserved with windows, the test section functional window is installed at the window opening position, and comprises a quartz glass test section observation window, a measurement functional window and a top square observation window. 4. The functional window of the test section is provided with a functional window cylindrical bulge and a functional window cylindrical pit, the functional window cylindrical bulge is positioned, and the functional window cylindrical pit is additionally provided with a high-strength magnet to be matched and connected with the test section shell. 5.
