hello everyone this is Jordan Rogers and
00:00:08.210 00:00:08.220 today I'm going to show you a short demo
00:00:09.980 00:00:09.990 of the essential asset monitoring
00:00:11.749 00:00:11.759 solution for air cooled heat exchangers
00:00:13.549 00:00:13.559 let's get started the first screen we
00:00:16.760 00:00:16.770 see here is the home page from here you
00:00:19.040 00:00:19.050 can see the status of each asset being
00:00:20.660 00:00:20.670 monitored right now all the assets are
00:00:22.849 00:00:22.859 healthy as indicated by the green boxes
00:00:24.830 00:00:24.840 and the health values shown I am now
00:00:26.960 00:00:26.970 going to dive in for more detail on the
00:00:28.849 00:00:28.859 air cold heat exchanger what we see here
00:00:33.410 00:00:33.420 is the air cooled heat exchangers
00:00:34.910 00:00:34.920 process display you'll notice the health
00:00:36.889 00:00:36.899 values reported at the top left along
00:00:38.900 00:00:38.910 with any active alarm text right now the
00:00:41.090 00:00:41.100 exchanger is healthy so there is no
00:00:42.830 00:00:42.840 alarm text shown you can see the value
00:00:44.930 00:00:44.940 and status of each input on this page as
00:00:46.729 00:00:46.739 well
00:00:48.850 00:00:48.860 this particular exchanger is a fixed
00:00:51.500 00:00:51.510 louver fixed-pitch variable speed fan
00:00:53.479 00:00:53.489 however this could have easily been a
00:00:55.520 00:00:55.530 variable pitch or a variable liver
00:00:57.229 00:00:57.239 position fan in those cases the
00:00:59.360 00:00:59.370 application would use pitch or louver
00:01:01.400 00:01:01.410 position in the same way as it uses
00:01:03.020 00:01:03.030 speed the calculated values are shown on
00:01:05.810 00:01:05.820 the right those include changes in the
00:01:07.850 00:01:07.860 process fluid and air temperatures along
00:01:09.889 00:01:09.899 with calculated heat transfer
00:01:11.330 00:01:11.340 coefficient and fouling factor let's now
00:01:15.139 00:01:15.149 go over to the inputs tab on the inputs
00:01:17.749 00:01:17.759 page you can see the current value the
00:01:19.580 00:01:19.590 average and the baseline value for each
00:01:21.410 00:01:21.420 input there's also a trend window
00:01:23.359 00:01:23.369 available here I'm going to add the
00:01:25.490 00:01:25.500 overall and peak view vibration values
00:01:27.590 00:01:27.600 to the trend to do that simply click on
00:01:29.419 00:01:29.429 the value for each input you would like
00:01:31.160 00:01:31.170 to trend
00:01:35.520 00:01:35.530 the baseline values represent a snapshot
00:01:38.050 00:01:38.060 of the data that has been captured under
00:01:39.790 00:01:39.800 normal operating conditions once the
00:01:42.190 00:01:42.200 baseline is captured all alerts are
00:01:43.960 00:01:43.970 calculated as a deviation from this
00:01:45.910 00:01:45.920 normal operating condition I am now
00:01:49.510 00:01:49.520 moving over to the configuration tab
00:01:51.220 00:01:51.230 from here you can configure the alarms
00:01:53.440 00:01:53.450 to see the details for the alarm
00:01:55.330 00:01:55.340 configuration of a specific input simply
00:01:57.820 00:01:57.830 click on the input name you'll see the
00:01:59.740 00:01:59.750 associated dialog box open up on the
00:02:01.900 00:02:01.910 right you can click the question mark
00:02:03.550 00:02:03.560 for more help on configuring alarms
00:02:05.880 00:02:05.890 let's make this demo a little more
00:02:08.050 00:02:08.060 interesting and look at the case where
00:02:09.730 00:02:09.740 the fan is experiencing high vibration
00:02:11.830 00:02:11.840 due to resonance
00:02:17.120 00:02:17.130 the active alert is now for potential
00:02:19.850 00:02:19.860 resonance condition this is a warning
00:02:22.010 00:02:22.020 alarm to understand what triggered this
00:02:24.410 00:02:24.420 alert I'm going to add one more value to
00:02:26.390 00:02:26.400 the trend this time I'm going to add the
00:02:28.880 00:02:28.890 speed the reason I am looking at this
00:02:31.040 00:02:31.050 value is because there are known
00:02:32.390 00:02:32.400 resonance frequencies for the fans motor
00:02:34.400 00:02:34.410 by looking at the speed we can determine
00:02:36.770 00:02:36.780 if we are operating in the known
00:02:38.450 00:02:38.460 resonance bands at this point none of
00:02:40.970 00:02:40.980 the vibration inputs are high
00:02:45.010 00:02:45.020 let's look now at the conditions that
00:02:47.360 00:02:47.370 cause the resonance detected alert to be
00:02:49.490 00:02:49.500 active keep an eye on the vibration
00:02:51.470 00:02:51.480 measurements of the trend you'll see
00:02:53.270 00:02:53.280 that the peak view one value is
00:02:54.590 00:02:54.600 increasing and is now high look at the
00:02:58.100 00:02:58.110 health value and alarm we are showing
00:03:00.070 00:03:00.080 35% health and a critical alert for
00:03:02.750 00:03:02.760 resonance detected in this case we are
00:03:04.910 00:03:04.920 looking at multiple parameters to
00:03:06.500 00:03:06.510 determine the fault condition now that
00:03:08.540 00:03:08.550 we have high vibration and are operating
00:03:10.850 00:03:10.860 at a known resonance speed the severity
00:03:12.770 00:03:12.780 and confidence level of the fault have
00:03:14.720 00:03:14.730 increased let's now go back to the
00:03:17.690 00:03:17.700 process page we can clearly see the
00:03:19.820 00:03:19.830 critical health and the resonance all
00:03:21.410 00:03:21.420 are active at the top left we also have
00:03:23.840 00:03:23.850 an indication of high vibration with the
00:03:25.760 00:03:25.770 flashing red text
00:03:29.720 00:03:29.730 with this indication of resonance
00:03:31.760 00:03:31.770 problems the user can now make changes
00:03:33.740 00:03:33.750 to the operation of the air-cooled heat
00:03:35.509 00:03:35.519 exchanger to no longer operate in a
00:03:37.490 00:03:37.500 resonance band
00:03:45.430 00:03:45.440 that concludes the demo of the essential
00:03:47.740 00:03:47.750 asset monitoring solution for air-cooled
00:03:49.810 00:03:49.820 heat exchangers I hope this has been
00:03:51.550 00:03:51.560 helpful to you and that you can see the
00:03:53.230 00:03:53.240 benefits of monitoring the health of
00:03:54.850 00:03:54.860 this asset
