The amusing operator
Thread Content
A high-temperature pump was installed; after the seal was replaced, the pump was started up for warming up, and then the operator left. The units we are maintaining still have their bearing temperatures and vibrations being monitored at present. The bearing on the non-driving side was measured at 60°C.:funk: It reached 60°C right when it started operating, and after a while it rose to 65°C℃ ； Upon inspection, it was found that the valve for supplying cooling water to the bearing box was not open; it was quickly opened, and the temperature dropped. If we hadn’t been there at the time, I guess that bearing would have been ruined again; it’s lubricated with oil mist{and thus dies even faster}. I went to argue with the operator, and he said, “Was it me who did this?” "It’s frustrating – when you deal with irresponsible operators, those who are responsible for maintenance have a hard time. Many pumps get damaged by these operators, and there’s nothing that can be done about it. :L
Yes, how are the pre-driving checks carried out? . . . . . . . . . . . . . . . . .
These guys are full of anger; because of them, we don’t know how much work we’ve done for nothing
It’s right that you stay where you are, but for the production workshop, this should be done first by the equipment technician or the equipment supervisor, not by the operators; the operators should work under the supervision of the equipment technician or supervisor. This kind of work requires prior contact with the equipment operator or equipment supervisor, and their presence is necessary; otherwise, it is impossible to communicate with the operators, unless they are operators you have worked with before, know well, and who are responsible.
The pre-startup checks were not thorough, and the operation of the pump was not monitored after it started running. The operator was a bit careless. You all have worked hard. Perhaps he thinks that since you’ve just had it serviced, there’s definitely no problem.
It can be reported upwards, and with solid evidence, there’s no need to worry that the problem won’t be resolved.
It’s actually a matter of a sense of responsibility; in situations like this, only by presenting solid evidence and reporting it for severe punishment can we prevent such problems from recurring. But still, kudos for your work attitude :)
Performance-based, with video surveillance.
It’s useless to look for operators for this; if you need to find someone, look for their equipment technicians or equipment supervisors instead
Both parties are at fault for failing to conduct proper inspections; after the equipment is repaired, the mechanic should also go to the site to verify things.
The key issue is that there is no written set of work processes. You say that someone lacks a sense of responsibility – what is the criterion for that? Some time ago in Canada, their operators followed a set workflow. What are the actions involved in shutting down a pump for maintenance, and what is the sequence? ； The steps and standards for handing over the system after maintenance are clearly listed. For example, if a pump breaks, it’s not simply repaired and put back into use; instead, a report must be prepared to analyze the reasons for the problem. If it is the operator’s responsibility, then check whether the operator violated procedures; if not, then modify the workflow. If it’s not possible to determine whose responsibility it is, then list the possible causes and observe these possibilities.
