Embodiment 1

[0050] refer to figure 1 , this embodiment provides an experimental device for a compressor, the compressor includes an impeller 1 and a diffuser 2, and the experimental device for the compressor includes a fixed frame 7, a flow channel shell, a gas collection chamber 5 and a fixed part 4; The channel shell is arranged in the fixing frame 7, the flow channel shell is deformable, the air inlet 313 and the air outlet 323 are arranged on the flow channel shell, the impeller 1 and the diffuser 2 are both arranged in the flow channel shell, and are When the fluid in the channel shell flows upward, the diffuser 2 is arranged behind the impeller 1; the gas collection chamber 5 is connected to the air outlet 323; between.

[0051] It should be noted that, due to the deformability of the runner shell, when it is necessary to replace the impeller 1 and the diffuser 2 with different specifications, only the shape and specification of the runner shell need to be changed, and the runner s...

Embodiment 2

[0086] This embodiment provides an experimental method for a compressor, which is applied to the experimental device of the compressor in Embodiment 1, and the experimental method includes:

[0087] S1, according to the impeller and the diffuser of the compressor to be tested, determine the structure of the corresponding flow channel shell.

[0088] S2, complete the assembly of the flow channel casing, the impeller and the diffuser.

[0089] S3, the fixing part is filled between the runner shell and the fixing frame.

[0090] S4, the flow channel shell is communicated with the gas collection chamber.

[0091] It should be noted that since the flow channel shell has deformability, in step S1, the structure of the corresponding flow channel shell is determined according to the impeller and the diffuser of the compressor to be tested, and the flow channel shell can be quickly designed It is not necessary to design a unique volute for different specifications of impellers and di...

Abstract

The invention relates to the technical field of compressor equipment, and discloses an experimental device and method for a compressor, the compressor comprises an impeller and a diffuser, and the experimental device for the compressor comprises a fixing frame; the flow channel shell is arranged in the fixing frame, the flow channel shell has deformability, an air inlet and an air outlet are formed in the flow channel shell, the impeller and the diffuser are both arranged in the flow channel shell and in the flow direction of fluid in the flow channel shell, and the diffuser is arranged behind the impeller; the gas collecting chamber is communicated with the gas outlet; the fixing part is located in the fixing frame and further arranged between the flow channel shell and the fixing frame, the flow channel shell has deformability, so that the flow channel shell can be repeatedly used, a unique volute does not need to be designed for impellers and diffusers of different specifications, the cost of a compressor test is reduced, the test period is shortened, and in addition, the test efficiency is improved. The fixing part can ensure the leakproofness of the flow channel shell, and meanwhile, can limit the deformation of the interior of the flow channel shell to the exterior of the flow channel shell, thereby ensuring that the experiment of the compressor can be carried out.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to an experimental device of a compressor and an experimental method thereof. Background technique [0002] Compressed air energy storage technology is considered to be the most potential large-scale and long-term energy storage technology, and it is very important to build a new power system with new energy as the main body. The compressor is the core component of the compressed air energy storage technology, and the performance of the compressor directly affects the performance of the entire system. Different from traditional industrial compressors, the compressors of compressed air energy storage systems have large power levels and high single-stage pressure ratios. Their performance parameters often need to be obtained through thermodynamic analysis of the entire system, and there are usually no model stages available for reference. , which needs to be developed fr...
