Introduction


A few of the rotating machines in your plant have the criticality to bring production to a halt. ¿©·¯ºÐÀÇ »çÀÌÆ®¿¡¼­ °¡µ¿ÇÏ°í ÀÖ´Â ¸î¸î ȸÀü±â°èµéÀº »ý»êÁß´Ü¿¡ À̸¦ ¸¸Å­ Áß¿äÇÑ ¿ªÇÒÀ» ¸Ã°í ÀÖÀ» °ÍÀÌ´Ù. On top of a shutdown system installed on this equipment to prevent catastrophic failure, it is interesting to think about having continuous health information about these machines. Roughly 50% of machinery damages, leading to downtime, are linked to process, and 90% of them are predictable – even manageable. ½Ã½ºÅÛÀÇ µ¹¹ßÁ¤Áö´Â Àç¾Ó¿¡ °¡±î¿î ¼öÁØÀÇ ÇÇÇظ¦ À¯¹ßÇÒ ¼öµµ ÀÖÀ¸¹Ç·Î ÀÌ·¯ÇÑ ±â°è¿¡ ´ëÇÑ Áö¼ÓÀûÀÎ °Ç°­»óÅ¿¡ ´ëÇÑ Á¤º¸´Â ¸Å¿ì Áß¿äÇÏ´Ù. ´ë·« ±â°è¼ÕÇØÀÇ 50%Á¤µµ´Â °øÁ¤ÀÇ Á¤Áö·Î À̾îÁö¸ç ±× ÁßÀÇ 90%´Â ¿¹ÃøÇÒ ¼ö ÀÖ¾ú´Ù´Â °ÍÀº »ý°¢ÇØ º¼ ¸¸ÇÑ »çÇ×ÀÎ °ÍÀÌ´Ù.

The continuous surveillance was set up in a very effective way for the customer and analyst: 

For the Customer: Easy detection, fast diagnosis and monitoring from the friction issue on a critical mixer asset with low upfront investment and lower costs than manual/traditional online monitoring.

equipment, plant overview,

The chemical plant produces ultra-fine thermoplastic powder for the automotive, coating, and cosmetics industry.

The Wi-care system is set up with one sensor on the electrical drive, and two sensors on the fan shaft. Outlined below is the standard spectrum collected with the Wi-care wireless monitoring system at the fan bearing coupling side. Display is in acceleration units G PK. The four dominant peaks from the right side of the screen show the bearing fault frequency and its harmonics. Seen below is a spectrum and wave form measurement performed with portable data collector on the same exact point,bearing on the fan,coupling side. ³×°³ÀÇ ÁÖ¿äÁÖÆļö ÇÇÅ©´Â º£¾î¸µ°áÇÔÁÖÆļö¿Í Çϸð´ÐÀ» ³ªÅ¸³»°í ÀÖ´Ù.

Same predominant bearing fault on the Wi-care and portable data collector measurement in April 2014.   We detected an obvious spectral peaks and noise due to friction on the fan bearing non coupling side. This revealed a typical lubrication defect. ¸í¹éÇÑ ½ºÆåÆ®·³ ÇÇÅ©¿Í ³ëÀÌÁ º¼ ¼ö ÀÖ¾ú°í ÀÌ °ÍÀº ÀüÇüÀûÀÎ À±È°ÀÇ ¹®Á¦ÀÌ´Ù. The fault is important and justify an action. We can also see a fault frequency on the fan bearing coupling side at 5.251 order. The amplitude gives grounds for concern but does not justify change out of the bearing at this time. We recommend that the Auto-Lubricator be checked to ensure it is performing correctly. In addition We will monitor the bearing fault frequency and friction trend with Wi-care in order to control lubrication and follow bearing fault degradation.  Following the diagnosis and remedial action, Wi-care provided a clear trending of data to the operators and predictive team.
