Problems solved by technology

However, due to the large variety of model levels and their different characteristics, there are many ways to combine model levels, which requires a high level of experience for designers
Selecting model stages to design centrifugal compressors based on experience will result in limitations in the combination of selected model stages
The combination selected based on experience is not the optimal solution, and it is highly dependent on the experience of the designer and takes a long time
As a result, the efficiency of the centrifugal compressor is low, and the operating range is narrow, which is not conducive to achieving the purpose of energy saving and emission reduction

Embodiment Construction

[0021] Exemplary embodiments of the present disclosure will be described in more detail below 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 may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0022] As mentioned in the background art, at present, a designer usually chooses a model stage to design a centrifugal compressor based on experience. However, because there are many types of model stages with different characteristics, and there are many ways to combine model stages, the experience requirements for designers are relatively high. Selecting model stages to design centrifugal compressors based on experience will caus...

Abstract

The invention discloses a centrifugal compressor design system and relates to the field of centrifugal compressor design. The system mainly aims to eliminate the limitation of selecting a model levelaccording to experience, improve the efficiency of a designed centrifugal compressor and expand a working condition range. The system comprises a design input parameter determination device, a model level combination selection device, a gas physical parameter calculation device, a performance parameter calculation device, a model level combination judgment device and a design scheme generation device. Through the devices, a model level combination can be selected from a preset model level database according to design input parameters, and gas physical parameters corresponding to all-level inlet and outlet states of the centrifugal compressor in model level combination modeling are iteratively calculated according to the model level combination and modeling rules; whether the model level combination meets a preset optimal rule is judged according to performance parameters; if yes, a design scheme of the centrifugal compressor is generated; and if not, a model level combination is reselected according to the design input parameters till the preset optimal rule is met.

Description

technical field [0001] The invention relates to the field of centrifugal compressor design, in particular to a centrifugal compressor design system. 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...
