Description

Technical Field

[0001] The utility model belongs to the field of compressor disc research and experiment, and particularly relates to a compressor disc performance test device. Background Art

[0002] When a titanium alloy compressor disk is working, the stress and heat conditions at the center and edge are different. However, the microstructure of the disk obtained by forging is a uniform equiaxed structure across the entire cross-section, so the operating temperature has to be lowered or the service life has to be shortened. When performing physical and mechanical property analysis on a compressor disk, it is usually necessary to heat it to a temperature close to the actual operating temperature to simulate its performance under actual working conditions. However, current test devices usually heat the entire compressor disk, which is inconsistent with the actual working conditions of the compressor disk. Therefore, a device that can heat the area in different regions is designed to simulate the heating conditions in actual work. By applying different temperatures to test the compressor disk, a scientific basis can be provided for design and manufacturing. Utility Model Content

[0019] The following is a combination of the embodiments of the present invention Figure 1-Figure 3 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0020] like Figure 1 , a compressor disc performance test device, comprising a base 1, a fixing rod 3, a motor 7, a rotating rod 8 and an adjustable heating mechanism 9;

[0021] The base 1 is fixedly connected to the fixing rod 3, which is arranged horizontally. One end of the fixing rod 3 is rotatably connected to one end of the rotating rod 8, and the other end of the rotating rod 8 is connected to the motor 7. The compressor disk 12 is sleeved on the rotating rod 8.

[0022] The adjustable heating mechanism 9 is symmetrically arranged on the fixed rod 3 and the rotating rod 8. The adjustable heating mechanism 9 is used to heat different local positions of the compressor disk 12, so that heating areas with different temperatures are formed when the compressor disk 12 rotates; the adjustable heating mechanism 9 is fixedly arranged.

[0023] The top of the base 1 is fixedly connected to a fixed rod 3 via a support rod 2. The axis of the fixed rod 3 is horizontal and coaxial with the rotating rod 8. Two adjustable heating mechanisms 9 are provided, one on the fixed rod 3 and the other on the rotating rod 8. The fixed rod 3 and the adjustable heating mechanism 9 are fixed stationary, while the rotating rod 8 rotates under the power of the motor 7. The two symmetrical adjustable heating mechanisms 9 are located on either side of the compressor disk 12. During testing, the present invention can apply different heating temperatures to different radial regions of the compressor disk 12, simulating the actual operating temperature environment of the compressor disk 12 and more accurately reproducing its actual operating conditions. This allows for a comprehensive and in-depth analysis of the compressor disk 12's physical and mechanical properties, including fatigue life, thermal expansion coefficient, and cracking, providing strong support and an effective basis for its design and improvement. After the test, the compressor disk 12 can be analyzed for cracks, deformation, and other conditions using microscopes, infrared thermometers, direct visual inspection, and measurement.

[0024] In addition, the compressor disc 12 is sleeved on the spline sleeve 11, and the spline sleeve 11 is fixedly sleeved on the rotating rod 8. The compressor disc 12 and the spline sleeve 11 are connected by splines. A threaded sleeve 10 is provided at the end of the spline sleeve 11, and the threaded sleeve 10 is threadedly connected to the rotating rod 8. The threaded sleeve 10 and the spline sleeve 11 are respectively provided with annular protrusions, and the annular protrusions of the two together form an annular groove structure. The compressor disc 12 is sleeved on the annular groove, and the compressor disc 12 can be installed or removed by the threaded sleeve 10.

[0025] like Figure 2 , the adjustable heating mechanism 9 includes a connecting rod 901, an adjusting sleeve 902, a shaft sleeve 13 and a heating assembly;

[0026] The fixed rod 3 and the rotating rod 8 are both rotatably sleeved with the shaft sleeve 13, and the shaft sleeve 13 is fixedly set. The shaft sleeves 13 on the fixed rod 3 and the rotating rod 8 are respectively fixedly connected to multiple connecting rods 901, and the multiple connecting rods 901 are distributed circumferentially around the shaft sleeve 13; multiple adjusting sleeves 902 are adjustable on the connecting rod 901, and the side of each adjusting sleeve 902 is provided with the heating component; the heating components on the fixed rod 3 and the rotating rod 8 are arranged opposite to each other and are located on both sides of the compressor disk 12.

[0027] Specifically, the side of the adjustment sleeve 902 is threadedly connected to a stop bolt 903, which abuts the connecting rod 901 to lock the adjustment sleeve 902 in place. Tightening the stop bolt 903 also locks the adjustment sleeve 902 in place. The connecting rods 901 are perpendicular to the axes of the fixed rod 3 and the rotating rod 8, and multiple connecting rods 901 are arranged in a circular array. By adjusting the positions of the multiple adjustment sleeves 902, different heating zones can be adjusted and compressor disks 12 of different sizes can be accommodated.

[0028] Furthermore, the heating assembly includes a telescopic rod, a pressure tank body 908 and a heating device 909; one end of the telescopic rod is fixedly connected to the side of the adjustment sleeve 902, the telescopic rod is perpendicular to the compressor disk 12, and the other end of the telescopic rod is fixedly connected to the pressure tank body 908. The pressure tank body 908 has a tank body facing the compressor disk 12, and the heating device 909 is installed in the tank body.

[0029] The telescopic rod is perpendicular to the connecting rod 901 and parallel to the axis of the fixed rod 3 and the rotating rod 8. By adjusting the telescopic rod, the position of the heating device 909 can be adjusted to adapt to compressor discs 12 of different thicknesses.

[0030] like Figure 3 The pressure tank body 908 is an arc-shaped structure, and the pressure tank bodies 908 on the multiple adjustment sleeves 902 are concentrically arranged. The heating device 909 is a conventional technology, such as a heating wire, which is arranged in the tank body of the pressure tank body 908. The heating device 909 is distributed in an arc shape, which can increase the contact area and improve the heating efficiency.

[0031] Furthermore, the telescopic rod includes a cross bar 904, a locking bolt 905, a spring 906 and a sliding rod 907; one end of the cross bar 904 is fixedly connected to the side of the adjustment sleeve 902, and the other end of the cross bar 904 is provided with a blind hole, and the spring 906 is provided in the blind hole.

[0032] Specifically, the spring 906 is in a compressed state.

[0033] There are two implementation modes of the present invention:

[0034] 1. The pressure tank body 908 is spaced apart from the compressor disk 12 .

In this embodiment, only the compressor disk 12 is heated.

[0035] 2. The pressure tank 908 is fitted onto the compressor disk 12, and the locking bolts 905 are loosened. The open end surface of the pressure tank 908 is fitted onto the compressor disk 12. The pressure tank 908 exerts a certain pressure on the compressor disk 12. In this embodiment, the compressor disk 12 is subjected to the dual effects of heating and pressurization, simulating the stress conditions of the compressor disk 12 during actual operation, allowing analysis of the deformation of the compressor disk 12.

[0036] Furthermore, the base 1 is slidably connected to a support base 6 , the motor 7 is mounted on the support base 6 , and one end of the rotating rod 8 away from the fixed rod 3 is rotatably connected to the support base 6 .

[0038] In addition, for the adjustable heating mechanism 9 on the rotating rod 8, one of the connecting rods 901 is fixedly connected to the base 1; for the adjustable heating mechanism 9 on the rotating rod 8, one of the connecting rods 901 is fixedly connected to the slide 5; thereby achieving the fixation of the two adjustable heating mechanisms 9.

[0039] Furthermore, the end of the fixed rod 3 is fixedly connected to the protrusion, and the protrusion is rotatably inserted into the connection hole at the end of the rotating rod 8. A bearing can be provided on the protrusion to rotate in the connection hole.
