Outline
To address the issues of repetitive design，high cost，and optimization difficulties in the series development of blower volutes caused by a single design process and limited software functionality，an adjustable partition plate is adopted to achieve serialized structural design of the volute.By optimizing the width and height of the partition plate to adapt to the flow channel cross‑section requirements of different volutes，the maximum sharing of volute components across blower units is realized.Combined with CFD calculations and flow field analysis，the performance quality and operating condition adaptability of the serialized products are ensured，and the reliability of the numerical simulation is verified through experiments.The results show that when using the adjustable partition plate for volute serialization design，the optimal range for the partition plate height D4/D2 is 1.65~1.72；when the partition plate width is greater than 5 mm，optimizing its structure can improve the flow field performance of the serialized volute.The blower units adopting the serialized volute structure have a wide operating range，with relative variability efficiencies of each unit all exceeding 82.5%，and total pressure ratios greater than 1.8，and they have been well applied in wastewater treatment energy‑saving projects.This study can provide a reference for the serialized design of blower volutes.
