Is there a dedicated person in charge of the condition monitoring of large compressors?
Thread Content
1 Petrochemical companies have a large number of large-scale compressors; in the past, each company had a team of specialists responsible for condition monitoring. 2 With fewer staff members, does your company still have dedicated personnel in charge of condition monitoring? 3 If it is necessary to evaluate the unit’s status, what approach does your organization take: hiring experts at a cost, not conducting any evaluation, seeking assistance from headquarters, or something else?
Our organization still has staff dedicated to condition monitoring, and we have also installed numerous online condition monitoring systems. On average, offline condition monitoring is carried out once a month on key large-scale machinery units, with an assessment report on the results of such monitoring being prepared.
There’s nothing else; only an offline test is performed once a month.
It definitely needs to be monitored by a dedicated person; it seems that our factory pays Shenzhen Chuangwei Alstom for this service. It mainly monitors the vibration amplitude of the unit, vibration frequencies (0.5, 1, 2, 2.5 times the frequency), vibration phase, and trend changes, etc. The price is likely to be expensive.
Online monitoring of compressors is generally necessary, as it helps to prevent unnecessary accidents and reduces the number of planned shutdowns. By focusing on prediction and diagnosis, it is possible to take appropriate actions. It is recommended to use an online fault diagnosis system, and it is best to include as many process parameters as possible. It’s just personal advice
Our company used to rely on part-time staff, but now we have full-time employees; moreover, large-scale units are equipped with SYSTEM1, which requires professionals to operate them.
The modern refineries with a capacity of tens of millions of tons are all designed to utilize online monitoring systems. The projects undertaken by our company in recent years have all adopted online monitoring; older facilities, on the other hand, use offline monitoring. The company has a dedicated team for monitoring, and key pumps in these facilities are also subject to weekly offline inspections. Inspection and analysis reports are prepared on a monthly basis to provide a basis for predictive maintenance of the equipment. Special management measures are applied to equipment that is not operating properly, with frequent inspections and observations, and reports are generated as needed!
Our organization designates specific personnel to handle it, and simple issues are resolved on our own； For special problems, it is generally necessary to consult the manufacturer or seek expert advice.
I am the one at Chuangweishi responsible for providing diagnostics to clients. Some clients have signed contracts for regular diagnostics, while others reach out to us when they encounter temporary issues; in most cases, these clients already have someone in charge of this task. All of our clients have received training from us. Please add my contact email as required: mirook@126.com. My QQ number is: 42379647. Feel free to get in touch.

There are personnel responsible for condition monitoring, as well as online condition monitoring systems. Offline condition monitoring is carried out once a week on key large-scale equipment, and an assessment report on the results of this offline monitoring is prepared.
Now, in most cases, specialized technical personnel are in charge of managing the expensive equipment, but some organizations still have dedicated staff for this task; each approach has its advantages and disadvantages. We usually solve our own problems
