机械振动故障检测仪的设计

he vibration is an important inherent property of the engineering machine and an important parameter of the machine circulating appearance and fault testing. According to middle and low frequency rotating machine, it has designed a convenient, fast, intelligent machinery vibration testing instrument. The design is based on single-chip design. It described the collectivity design of the hardware and software. Taking the vibration testing as the lord, it as to provide dependable data support for fault diagnosis of the on-line monitor circulates equipments. The text simply introduced each part of the instrument. The instrument has a simple circuit, low price, high performance. It can be used for mine excavator rotating machinery fault detection, etc.
