Mill system condition monitoring and diagnosis Bit. 3. Monitoring equipment to monitor equipment failure by the system cycle is the average Vibram Five Fingers Outlet between the present, the equipment condition monitoring and diagnosis to determine the working hours, it will store the different objects in two specific processes: first, the vibration signal in the field and the same object at different times vary. In the test, the test record, which includes sensors, signal amplifiers, data measurement points in mind if you find changes, and there is a certain trend, loggers, etc.; and then the signal off-line analysis. Vibram Five Fingers On Sale It consists of just measuring period should be shortened; newly installed devices and determine signal data acquisition, processing and characterization of Figures 4 and 5 minutes before and after the overhaul of monitoring cycle should be shortened. To this end, we shall not matching the vibration signal test and analysis system. Specific situation to determine the monitoring cycle: the original factory 2.7 × 4M12 vibration acceleration lIGZ2 I type lIMHc-I-type {l sensors record signals Il Il vibrometer signal tape recorder i prince Yu Lan 4 vibration signal test system, two two hundred 1 r1 barrier wall down the whole Church to force the plastic plaque Marina circle prince Yu Jue 1 5 4 signal analysis system. Case Study workshop factory made more than one edge of synchronous motor-driven mill drive systems, specifications for the 2.7x4M, transmission structure diagram shown in Figure 6, the main shaft rotation frequency fr a 3.33Hz , large and small gear, respectively 178,17, gear mesh frequency fz = 56.6Hz,, extravagant machine simplified rotation frequency 0.318Hz. During operation, the mill found a strong powertrain vibration vice, we A, B two bearing vibration tested, Figure 7-8 is the results of its analysis. Star Man i hope I {j-po rate cutting and its high harmonics and sidebands, and the second, third octave harmonic energy than an energy bigger; Wholesale Vibram Five Fingers prince Yu 6 mill factory 2.7 × 4M transmission structure to indicate prince Yu Figure  two spectrum, there has been 2fr, 4fr, 6fr other spindle axis high-frequency harmonics, and its interval 2fr, in addition to the frequency interval of 0.5fr side, we can see that the neutral is not good shaft, the shaft has occurred loose parts; there 6fr maximum amplitude, probably due to coupling deterioration caused by long-running precision.
