Example Embodiment

[0039] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0040] As mentioned in the background art, at present, the designer usually selects a model level to design a centrifugal compressor based on experience. However, due to the many types of model stages and their different characteristics, there are many model-stage combinations, which require a high designer’s experience. Choosing a model-stage to design a centrifugal compressor based on experience will result...

Abstract

The invention discloses a method for designing a centrifugal compressor and relates to the field of centrifugal compressor design. The main purpose is to eliminate the limitation of the model level selected based on experience, and to improve the efficiency of the centrifugal compressor designed and the range of broadened working conditions. The method includes selecting a model level combinationfrom a preset model level database according to design input parameters of the centrifugal compressor, wherein the preset model level database stores various tested model level data; according to themodel level combination and modeling rules, performing iterative computation on gas property parameters corresponding to inlet and outlet states at each level of the centrifugal compressor; accordingto the gas property parameters, performing iterative computation on performance parameters corresponding to the centrifugal compressor; according to the performance parameters, determining whether themodel level combination conforms to a preset optimal rule; if yes, generating a design scheme of the centrifugal compressor; and if not, reselecting the model level combination and performing calculation, until the model level combination conforms to the preset optimal rule. The method is suitable for designing the centrifugal compressor.

Description

technical field [0001] The invention relates to the field of centrifugal compressor design, in particular to a centrifugal compressor design method. Background technique [0002] As a general machine, centrifugal compressors are widely used in various national economic fields, such as metallurgy, chemical industry, oil refining, pharmaceuticals, air separation and other industries. Due to its importance, it has been hailed as the heart device in these devices. Since the flow rate, pressure ratio, and inlet temperature of compressors are different in various devices, and the media components are even more diverse, so the design parameters of most centrifugal compressors are different, and they are individually designed and single-stage compressors. products produced. Due to the high power of a single compressor and the improvement of the operating efficiency of the centrifugal compressor, it is of great significance to save energy. [0003] The design methods of centrifuga...
