00:00:05.450 hello everyone this is Jordan Rogers and 00:00:08.21000:00:08.220 today I'm going to show you a short demo 00:00:09.98000:00:09.990 of the essential asset monitoring 00:00:11.74900:00:11.759 solution for air cooled heat exchangers 00:00:13.54900:00:13.559 let's get started the first screen we 00:00:16.76000:00:16.770 see here is the home page from here you 00:00:19.04000:00:19.050 can see the status of each asset being 00:00:20.66000:00:20.670 monitored right now all the assets are 00:00:22.84900:00:22.859 healthy as indicated by the green boxes 00:00:24.83000:00:24.840 and the health values shown I am now 00:00:26.96000:00:26.970 going to dive in for more detail on the 00:00:28.84900:00:28.859 air cold heat exchanger what we see here 00:00:33.41000:00:33.420 is the air cooled heat exchangers 00:00:34.91000:00:34.920 process display you'll notice the health 00:00:36.88900:00:36.899 values reported at the top left along 00:00:38.90000:00:38.910 with any active alarm text right now the 00:00:41.09000:00:41.100 exchanger is healthy so there is no 00:00:42.83000:00:42.840 alarm text shown you can see the value 00:00:44.93000:00:44.940 and status of each input on this page as 00:00:46.72900:00:46.739 well 00:00:48.85000:00:48.860 this particular exchanger is a fixed 00:00:51.50000:00:51.510 louver fixed-pitch variable speed fan 00:00:53.47900:00:53.489 however this could have easily been a 00:00:55.52000:00:55.530 variable pitch or a variable liver 00:00:57.22900:00:57.239 position fan in those cases the 00:00:59.36000:00:59.370 application would use pitch or louver 00:01:01.40000:01:01.410 position in the same way as it uses 00:01:03.02000:01:03.030 speed the calculated values are shown on 00:01:05.81000:01:05.820 the right those include changes in the 00:01:07.85000:01:07.860 process fluid and air temperatures along 00:01:09.88900:01:09.899 with calculated heat transfer 00:01:11.33000:01:11.340 coefficient and fouling factor let's now 00:01:15.13900:01:15.149 go over to the inputs tab on the inputs 00:01:17.74900:01:17.759 page you can see the current value the 00:01:19.58000:01:19.590 average and the baseline value for each 00:01:21.41000:01:21.420 input there's also a trend window 00:01:23.35900:01:23.369 available here I'm going to add the 00:01:25.49000:01:25.500 overall and peak view vibration values 00:01:27.59000:01:27.600 to the trend to do that simply click on 00:01:29.41900:01:29.429 the value for each input you would like 00:01:31.16000:01:31.170 to trend 00:01:35.52000:01:35.530 the baseline values represent a snapshot 00:01:38.05000:01:38.060 of the data that has been captured under 00:01:39.79000:01:39.800 normal operating conditions once the 00:01:42.19000:01:42.200 baseline is captured all alerts are 00:01:43.96000:01:43.970 calculated as a deviation from this 00:01:45.91000:01:45.920 normal operating condition I am now 00:01:49.51000:01:49.520 moving over to the configuration tab 00:01:51.22000:01:51.230 from here you can configure the alarms 00:01:53.44000:01:53.450 to see the details for the alarm 00:01:55.33000:01:55.340 configuration of a specific input simply 00:01:57.82000:01:57.830 click on the input name you'll see the 00:01:59.74000:01:59.750 associated dialog box open up on the 00:02:01.90000:02:01.910 right you can click the question mark 00:02:03.55000:02:03.560 for more help on configuring alarms 00:02:05.88000:02:05.890 let's make this demo a little more 00:02:08.05000:02:08.060 interesting and look at the case where 00:02:09.73000:02:09.740 the fan is experiencing high vibration 00:02:11.83000:02:11.840 due to resonance 00:02:17.12000:02:17.130 the active alert is now for potential 00:02:19.85000:02:19.860 resonance condition this is a warning 00:02:22.01000:02:22.020 alarm to understand what triggered this 00:02:24.41000:02:24.420 alert I'm going to add one more value to 00:02:26.39000:02:26.400 the trend this time I'm going to add the 00:02:28.88000:02:28.890 speed the reason I am looking at this 00:02:31.04000:02:31.050 value is because there are known 00:02:32.39000:02:32.400 resonance frequencies for the fans motor 00:02:34.40000:02:34.410 by looking at the speed we can determine 00:02:36.77000:02:36.780 if we are operating in the known 00:02:38.45000:02:38.460 resonance bands at this point none of 00:02:40.97000:02:40.980 the vibration inputs are high 00:02:45.01000:02:45.020 let's look now at the conditions that 00:02:47.36000:02:47.370 cause the resonance detected alert to be 00:02:49.49000:02:49.500 active keep an eye on the vibration 00:02:51.47000:02:51.480 measurements of the trend you'll see 00:02:53.27000:02:53.280 that the peak view one value is 00:02:54.59000:02:54.600 increasing and is now high look at the 00:02:58.10000:02:58.110 health value and alarm we are showing 00:03:00.07000:03:00.080 35% health and a critical alert for 00:03:02.75000:03:02.760 resonance detected in this case we are 00:03:04.91000:03:04.920 looking at multiple parameters to 00:03:06.50000:03:06.510 determine the fault condition now that 00:03:08.54000:03:08.550 we have high vibration and are operating 00:03:10.85000:03:10.860 at a known resonance speed the severity 00:03:12.77000:03:12.780 and confidence level of the fault have 00:03:14.72000:03:14.730 increased let's now go back to the 00:03:17.69000:03:17.700 process page we can clearly see the 00:03:19.82000:03:19.830 critical health and the resonance all 00:03:21.41000:03:21.420 are active at the top left we also have 00:03:23.84000:03:23.850 an indication of high vibration with the 00:03:25.76000:03:25.770 flashing red text 00:03:29.72000:03:29.730 with this indication of resonance 00:03:31.76000:03:31.770 problems the user can now make changes 00:03:33.74000:03:33.750 to the operation of the air-cooled heat 00:03:35.50900:03:35.519 exchanger to no longer operate in a 00:03:37.49000:03:37.500 resonance band 00:03:45.43000:03:45.440 that concludes the demo of the essential 00:03:47.74000:03:47.750 asset monitoring solution for air-cooled 00:03:49.81000:03:49.820 heat exchangers I hope this has been 00:03:51.55000:03:51.560 helpful to you and that you can see the 00:03:53.23000:03:53.240 benefits of monitoring the health of 00:03:54.85000:03:54.860 this asset
