阐述了矿用对旋轴流通风机变频改造的必要性,分析了SH-HVF系列高压调速器的技术特点,使用此型变频调速系统对FBCDZ-6-No22C-2×355型煤矿主通风机采用变频改造,并验证了改造前后的工作性能。
The necessity of frequency conversion retrofit of mine counter-rotating axial flow fan was expounded. The technical characteristics of SH-HVF series high-pressure governor were analyzed. By using this type of variable frequency speed regulation system, the design of FBCDZ-6-No22C-2 × 355 coal mine main Fan using frequency conversion transformation, and verified the performance before and after the transformation.
