A kind of packaging facilities mechanical Fault Monitoring of HV device embodiment 2 chosen based on measuring point

The present embodiment on the basis of plant machinery fault monitoring device embodiment 1, enter by the data to being monitored needed for measuring point Analysis is gone.

On Monitoring Data, vibration equipment data and the major class of device temperature data two are broadly divided into.For vibration equipment shape State, can be described, respectively including vibration displacement, vibration velocity, vibration acceleration by three parameters.Vibrating mass Fatigue is directly proportional to vibration velocity, and energy produced by vibrating square is directly proportional to vibration velocity, due to energy The result of transmission cause abrasion and other defect, therefore, in vibration diagnosis criterion, be by speed be defined comparing fit Preferably.And for low-frequency vibration, it is main just to consider due to the destruction that displacement is caused, its essence is the destruction of fatigue strength, Er Feineng The destruction of amount property;But for dither, then mainly it is considered as the influence of shock pulse and original paper resonance.Therefore, to big For most machines, excellent diagnostics parameter is speed, many in the world because it is the ideal parameters for reflecting oscillation intensity Vibration diagnosis standard is all as discriminant parameter using speed virtual value.

Because measuring point 1,2,3,5 is all located on actuating unit respectively, vibration frequency is higher, it can be considered to vibrating speed It is main monitoring object to spend, and with vibration displacement and vibration acceleration be auxiliary monitoring object;Measuring point 4,6 sets positioned at processing respectively Standby outside, vibration frequency is relatively low, it may be considered that with vibration displacement be main monitoring object, and is accelerated with vibration velocity and vibration It is auxiliary monitoring object to spend.

Additionally, for device temperature state, on the one hand, temperature is a characteristic parameter for characterizing electric automatization failure; On the other hand, the mechanical performance of material has close relationship with temperature again, and temperature is too high, not only makes machine components that softening etc. occurs Anomaly so that performance reduction, can also burn out part when serious.Therefore, temperature monitoring is also therefore and in mechanical equipment fault Vital status is accounted in the whole technical system of diagnosis.

In actual applications, device for detecting temperature can be installed in each measuring point, or temperature only is installed in specific measuring point and supervise Device is surveyed, measuring point 1,2,3 is such as set to the measuring point with device for detecting temperature, to the data monitoring of these three temperature monitoring points Two parts are all included, one is the too high monitoring of temperature, whether beyond specified standards real-time monitoring is carried out to temperature data;Another It is temperature ramp-up rate monitoring, the pace of change to temperature data carries out real-time monitoring, by the change to adjacent moment temperature value Whether change amplitude is excessive to carry out early warning, points out the unit exception that may occur.

The corresponding vibration data of measuring point selected by real-time monitoring or temperature data (can certainly simultaneously monitor selected measuring point pair The vibration data and temperature data answered, specifically can according to actual needs select corresponding Monitoring Data), comparative analysis its with The size of the warning value of setting, diagnoses to equipment fault type.
