Embodiment Construction
[0056] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.
[0057] A method for generating an adaptive performance curve of a compressor of the present invention comprises the following steps:
[0058] Step S1, by comparing with the actual working conditions, the rotation speeds selected in the embodiment are 13319r / min, 12685r / min, 11417r / min, 10148r / min, 8880r / min, and the relevant design performance parameters are converted into numerical forms;
[0059] Step S2, using similarity theory to obtain theoretical performance parameters under actual working conditions;
[0060] The performance conversion method adopted by the similarity theory is an approximate similarity transformation method;
[0061] The performance conversion method is divided into:
[0062] When the pressure ratio is less than 2.5, use the multi-transform algorithm;
[0063] When the pressure ratio is greater than 2.5, the half-temperat...
