Prevented an accident from occurring
Thread Content
Today, during the shift change, I went out for an inspection and found that the motor of the boiler feed pump was overheating; its cooling fans were damaged, and both the pump and the motor were vibrating severely. A burnt smell could be detected at the scene. I immediately called the operator to switch to the backup pump, which prevented an accident from occurring. It is estimated that if things had delayed a few more minutes, the motor would have burned out. Please share any experiences you’ve had in production!

Inspections for sulfuric acid production are extremely important; inspectors need to be highly responsible. We have encountered similar situations before, but they were all detected and resolved during inspections. Of course, when such incidents occur, the procedures require that the matter not be left unresolved until the cause of the accident is identified
During inspections, timing signs should be placed on site; over time, inertia sets in, and inspections are not carried out promptly, resulting in suboptimal outcomes.
The drain pipe on the boiler can break after being used for a long time to drain fluid; I don’t know why
We also encountered this issue when producing sulfuric acid: the instrument technician was very responsible and quietly planned to adjust the electric valve at the fan inlet during operation, without anyone in the production team being aware of it. As a result, the valve at the fan inlet was closed. Of course, the operators noticed this when they went to the site and requested that the valve be opened (the sulfur pump wasn’t stopped in time either). It took 2 to 3 minutes to open the valve, and the environmental protection department was called as a result. Haha
In actual production, different problems arise every day, and there are likely many such examples; everyone should share them to create a platform for communication.
Yes, the tail bearing of the boiler feed pump motor turned red due to overheating, and it was detected during inspections; fortunately, the same thing happened in that case as well. However, the motor has already been bored
Thank you all; this will be very helpful for our future work. Please feel free to give us more guidance in the future

Strict shift handover and inspection systems should be established, and equipment records should be kept to document in detail any incidents that occur with each piece of equipment and the actions taken to address them. 1. During shift handovers, employees from each shift must be present at the site to carry out the handover process, and a handover record must be signed to clarify the responsibilities for each time period. 2. During inspections, every stationary and moving piece of equipment must be checked, usually once every 2 hours. The operating parameters of each device must also be recorded. Equipment maintenance personnel from each shift should be designated as inspectors for their respective shifts (as the persons responsible for equipment maintenance). Inspection records are generally retained for two years before being discarded. 3. For devices that experience accidents, detailed records of the incident must be kept, including an analysis of the cause of the accident, the person responsible, the actions taken to resolve it, and information on the spare parts used. Those who manage to prevent accidents or contribute to improving the performance of the equipment should be rewarded accordingly.
