Fan is a key power plant in Taiyuan auxiliary temperature axial fans, axial fans due to the high efficiency and low energy consumption and are widely used. In actual operation. Many power plants because especially poor variable pitch axial fan axial fans reliability, frequent failure caused unplanned plant downtime or reduced load. Affecting the power generation unit. So Taiyuan small axial fans, to solve these problems fundamentally. Large-scale thermal power plants to improve the reliability of operation of axial fan is very necessary and urgent. This article explains the factors that affect the reliability of plant fans. It proposed to improve the reliability of the axial fan design and operation countermeasures. Shanxi nagorye blower limited liability company, to get the same amount of wind pressure in the case, for axial fan with strong forward blade and multi-blade impeller is conducive to increasing the cascade aerodynamic load Taiyuan resistant axial fan, impeller blades On the outer circumferential speed can significantly reduce the fan noise. 2, axial fans set at the volute tongue acoustic resonator, sound waves spread when a resonator, sound waves keep gas orifice aperture and cavity back and movement, so that part of the sound energy is lost due to heat loss making noise to get lower. Taiyuan small axial fans | Shanxi nagorye blower (certified) | axial fan blower is provided by Shanxi nagorye limited liability company. Shanxi nagorye Blower Co., Ltd. (www.sxgfj.cn) (www.sxfjgs.com) is an industry leader Shanxi Xinzhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs.
