Do people think there is a market for domestic condition monitoring of mechanical equipment, with vibration as the key parameter?
Thread Content
I have visited many chemical industry clients and found that they do not have any systems for monitoring the condition of moving equipment, with vibration being the main parameter monitored. In fact, such systems are very useful for reducing maintenance costs and minimizing downtime incidents related to moving equipment. So I’d like to ask everyone, especially those who work on maintaining mechanical equipment in factories, do you think it’s necessary? Thank you!
There are few online ones; we have handheld ones in each of our production workshops.
Monitoring vibration and temperature is essential, but the cost of doing so online is high; many companies are reluctant to incur such expenses, so offline testing is more common! Online monitoring (on large equipment) is a trend, including reciprocating and centrifugal types!
For ordinary equipment, adding this feature increases the cost slightly and offers little benefit; for our key equipment, such as compressors, vibration and displacement monitoring is implemented. . .
Generally, important critical units need to be online, while ordinary ones can be offline
I have two questions: 1. What is the reason why ordinary devices are not very useful? Does a broken device have little impact on production? Don’t general equipment break easily? 2. For critical equipment such as compressors, are they online-type? Which one is used more commonly? Thank you!
Generally, if there’s a problem with the equipment, it doesn’t affect production for the time being. Or, in the case of switching between pump A and pump B, normal operation of a centrifugal pump should not cause any vibration issues. Once the vibration becomes excessive, problems will arise with the mechanical seal, and the machine has to be stopped for maintenance. The vibration displacement of the compressor is monitored and connected to the unit’s alarm interlock system~~
The key issue is that the vibration analysis personnel are not competent enough. It is not possible to analyze correctly and determine the cause of the fault.
The online monitoring market is quite large, and it’s mainly the mainframe manufacturers who are involved in it. Because this relates to the significance of online monitoring, it requires professionals to carry out the monitoring and analysis.
In my opinion, status monitoring, and RCM as a consequence of it, remain more of a hype than anything concrete, even in Europe and the United States.
Online monitoring of equipment in domestic settings is rarely used. For critical equipment, online monitoring is primarily aimed at monitoring temperature; there are many external factors that can affect equipment vibration, which can easily lead to unnecessary shutdowns
