Design Of Machinery Vibration Examining Instrument

The machine vibration is the basic characteristic of the equipments circulate, it is reflected the basic parameter of the equipments movement appearance, passing by its change of monitor, it can be judged the movement appearance of the equipments accurately, discovered the fault breakdown of the equipments in early days, these have the important meaning for the earlier period diagnosis fault of the industry equipments.The paper designs the vibration examining instrument for the rotating machines of low frequency, it carries on the-line monitor of the circulating machine equipments. The biggest characteristics of the monitor taking the vibration examining as the lord and temperature examining as assist will be test the spot vibration parameter and the spot temperature parameters of the equipments to carry on monitor, save, printing and deliver at the same time, aim at the on-line monitor circulating equipments whether the abnormality, in order to provide the dependable data support for fault diagnosis, the ends of the monitor achieve the fast report of the circulating machine equipment.According to examining vibration sensor rectified output signal characteristic, designed and completed the corresponding vibration examining instrument system. Among them, the A/D conversion is the core of the electric circuit in the data collecting system, the adoption TLC2543, it is a high performance, low power to consume 12 bits high-speed A/D conversion, a saving resources, have the sample to keep and serial interface output function; The adoption AT89C52 of a machine system completes the data collecting and data processing and data displaying.The Software design using edit collected materials the language is completed under the Wave6000 integrated environment, It abopts model procedure designing method, including monitoring control and collecting data and processing data and displaing data and communication and miniature printer port procedure designing.Passing the control toward the processor 89C52, it can make other each chips completed each function and moderated work, the key is the control that the processor converts the machine to the A/D, according to the design index sign, it can make completly the most important function in the examination instrument smoothly-the vibration signal examination, thus carry out main function of the examination instrument.
