美国IRD公司推出的246型动平衡仪,是一种多用途的自动动平衡仪,采用交流电源或电池供电,既可作为一种便携式动平衡仪用于设备维修人员的现场动平衡测试,也可作为试验台式动平衡机的配套仪表使用。 246型动平衡仪采用窄带跟踪滤波器,可迅速自动完成单平面、双平面、力/力偶分离法动平衡测试,取代了传统动平衡过程中使用的矢量图和计算器。可同时显示两个振动速度传感器输入的信号幅值和相位,提供校正重量的大小及角度位置,利用数字字符显示屏指导用户完成动平衡的每个步骤。 该动平衡仪本身带有永久性存储器,存储50个不伺型式转子的平衡数据并可迅速调出。对于存储
United States IRD company introduced the 246 dynamic balancer is a versatile automatic balancer, AC power or battery-powered, either as a portable balancing instrument for equipment maintenance personnel on-site balancing test, but also Can be used as a benchtop balancing machine supporting the use of instrumentation. The 246-type dynamic balancer uses a narrow-band tracking filter to quickly and automatically complete single-plane, dual-plane, force / couple dual-action balancing tests that replace the traditional vector and calculator used in dynamic balancing. Simultaneous display of the amplitude and phase of the signals input by two vibration velocity transducers provides the size and angular position for weight correction, using the numeric character display to guide the user through each step of the balancing process. The dynamic balancer has permanent memory itself which stores the balance data of up to 50 non-servomotor type rotors and can be quickly recalled. For storage
