Description

Technical Field

[0001] The invention belongs to the field of rotary machinery, and in particular relates to an adjustable temperature regulating plate outside a rotor. Background Art

[0002] The temperature regulating plate is a functional component outside the rotor. Its main function is to utilize the difference in surface blackness coefficient and other components outside the rotor to adjust the heat transfer process inside the rotor along the axial direction, so as to achieve the purpose of adjusting the temperature distribution of the rotor side wall, thereby affecting the gas flow state inside the rotor.

[0003] The existing rotor external temperature control plate cannot be adjusted during the test. When conducting temperature control plate optimization tests on the same or multiple machines, temperature control plates of various sizes need to be processed. Each time the length or position of the temperature control plate is changed, the machine needs to be shut down, disassembled, reinstalled, and restarted. This method not only introduces errors caused by repeated start and stop of the machine, but also consumes a lot of manpower and material resources during the test. Summary of the invention

[0010] In the above technical solution, the thickness of the upper temperature regulating plate is smaller than the distance of the gap between the functional component and the sleeve.

[0011] In the above technical solution, the axial height of the upper temperature regulating plate is less than 1 / 3 of the height of the rotor, and its axial height is less than the axial height of the functional component.

[0012] In the above technical solution, the upper temperature regulating plate can freely move axially within the height range from the upper end of the sleeve to the lower end of the functional component.

[0013] In the above technical solution, the surface blackness coefficient of the lower temperature regulating plate, the middle temperature regulating plate and the upper temperature regulating plate is greater than 0.8.

[0014] In the above technical solution, the sleeve is arranged coaxially with the rotor.

[0015] In the above technical solution, the blackness coefficient of the inner surface of the sleeve is 0.1.

[0016] The beneficial effects of the present invention are:

[0017] The present invention provides an adjustable rotor outer temperature regulating plate during a test process, which adjusts the blackness coefficients of different axial positions outside the rotor during machine operation, thereby avoiding the operation steps of repeatedly starting and stopping the temperature regulating plate optimization test.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the adjustable temperature regulating plate outside the rotor of the present invention is further explained below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] like Figure 1 As shown, an adjustable temperature control plate outside a rotor includes a lower temperature control plate 1, a middle temperature control plate 2 and an upper temperature control plate 3, all of which are annular and arranged on the inner side of a sleeve 4 from bottom to top. The lower temperature control plate 1 is fixedly connected to the lower end of the inner side of the sleeve 4, the middle temperature control plate 2 is installed on the inner side of the lower temperature control plate 1 through an axially arranged slide rail, and the upper temperature control plate 3 is installed on the inner upper end of the sleeve 4 through a slide rail.

[0030] The axial height of the lower temperature regulating plate 1 is 1 / 5 to 1 / 3 of the height of the rotor 5 .

[0031] The axial height of the middle temperature regulating plate 2 is less than or equal to the axial height of the lower temperature regulating plate 1 .

[0032] The middle temperature regulating plate 2 is freely movable in the axial direction within the height range from the lower end to the upper end of the lower temperature regulating plate 1 .

[0033] The thickness of the upper temperature regulating plate 3 is smaller than the distance of the gap between the functional component 6 and the sleeve 4 .

[0034] The axial height of the upper temperature regulating plate 3 is less than 1 / 3 of the height of the rotor 5 , and the axial height of the upper temperature regulating plate 3 is less than the axial height of the functional component 6 .

[0035] The upper temperature regulating plate 3 is freely movable in the axial direction within the height range from the upper end of the sleeve 4 to the lower end of the functional component 6 .

[0036] The surface blackness coefficient of the lower temperature regulating plate 1, the middle temperature regulating plate 2 and the upper temperature regulating plate 3 is greater than 0.8.

[0037] The sleeve 4 and the rotor 5 are arranged coaxially.

[0038] The blackness coefficient of the inner surface of the sleeve 4 is 0.1, and the inner surface is the wall of the sleeve 4 close to the rotor 5 .

[0039] Working process of the present invention:

[0040] When the machine is operating normally, by adjusting the upper temperature regulating plate 3 and the middle temperature regulating plate 2 up and down, the blackness coefficient at the axial position covered by the annular temperature regulating plate is greater than 0.8, and the blackness coefficient at the axial position not covered by the annular temperature regulating plate is 0.1. The blackness coefficient in the axial area from the lower end of the functional component 6 to the upper end of the lower annular plate can be adjusted, thereby achieving the purpose of adjusting the temperature distribution on the wall of the rotor 5.

[0041] Taking the heat source at the upper end of the rotor as an example, the temperature adjustment effect of the adjustable temperature adjustment plate outside the rotor on the rotor wall surface of the present invention is as follows: Figure 2 As shown in the figure, during the test, an annular temperature control plate with a surface blackness coefficient greater than 0.8 was moved up and down along the axial direction on the inner surface of the sleeve with a surface blackness coefficient of 0.1 to change the surface blackness coefficient of the rotor outer axis from the lower end of the functional component to the upper end of the lower temperature control plate. By adjusting the different axial position schemes of the upper and middle annular temperature control plates, the temperature line shape and average temperature of the rotor wall can be adjusted, and the average temperature adjustment range is above 2°C. The temperature adjustment effect is shown in the figure. Figure 2As shown in the figure, Scheme 1 is the temperature control effect when the lower end of the upper temperature control plate 3 is flush with the lower end of the functional component 6, and the upper end of the middle temperature control plate 2 is flush with the upper end of the lower temperature control plate 1; Scheme 2 is the temperature control effect when the upper end of the upper temperature control plate 3 is flush with the lower end of the functional component 6, and the lower end of the middle temperature control plate 2 is flush with the upper end of the lower temperature control plate 1.
