一、概述旋转机械在运行时,需要经常检测它的振动大小。目前国内使用的小型测振仪,有的需用交流电源供电,有的虽用电池,但耗电太多;有的体积较大,有的用指针显示,精度较差,使用者感到多有不便。为此,南京工学院测振中心研制成ZXP-6型袖珍数字测振仪,用于测量机械振动的位移振幅和速度振幅。 First, an overview Rotating machinery in operation, the need to constantly detect the size of its vibration. At present, the domestic use of small vibrometer, and some need to use AC power supply, although some use batteries, but power consumption too much; some larger, some with the pointer shows poor accuracy, users feel more inconvenient. To this end, Nanjing Institute of vibration center developed ZXP-6 pocket digital vibrometer, used to measure the displacement amplitude and speed of mechanical vibration amplitude.
