Balance, Vibration, and Vibration Analysis - （平衡、振动和振动分析-）.pdf

Fan Application ® FA/108-00 A technical bulletin for engineers, contractors and students in the air movement and control industry. Balance, Vibration, and Vibration Analysis There are many factors that can have a substantial Based upon its particular operation and effect on the vibration level of air movement performance, every fan belongs to a Fan Application equipment; such as wheel balance, rotational speed, Category. (See Fan Application Categories chart.) drive components, motor operation and wiring. Responsible fan manufacturers balance the fan Providing equipment that operates well within impeller assemblies to allowable residual unbalance acceptable vibration levels requires consistent prior to assembly of the unit. These limits are based quality in production and attention to details. Only on ANSI S2.19 “Balance Quality of Rigid Bodies.” quality-driven companies spend the extra time and money required to make this kind of commitment. Fan Application Balance Quality Grade In this article, we will discuss wheel balancing, Category for Rigid Rotors/Impeller define the parameters and process of conducting BV-1 G 16 vibration tests, and review some typical vibration BV-2
