G4-73型送风机提高安全可靠性技术改造

Technology Tramsformation for Improvement of Security on Type G4-73 Centrifugal Fan

山西河坡发电有限责任公司送风机运行不稳定,冷风道振动严重,发生过叶轮飞车事故,经对G4-73型离心式风机性能试验表明,主要为风机性能与管网特性不匹配所致,对风机进行针对性技改后,技术性能和安全可靠性得到全面提高。

The power plant has the supply fan with unstable, serious vibration on cold air duet and fiequent accident of impeller rupture. In order to improve the security of fan performance, guarantee the unit safe runs and person safety, we carry out the technology transformation for improvement of security on type G4 - 73 centrifugal fan.
