What are the key points for maintaining mechanical equipment? Please share your experiences

If it’s in operation, let me tell you: for a single-stage pump, all that’s needed is to pay attention to the oil level, rotate the pump shaft, monitor vibration levels and temperature, switch the pump regularly, and take care of the inlet filter – that’s it. Also, keep some spare parts on hand. For large-scale units, the requirements are higher, so I won’t go into that detail.

Regarding fluoride pumps, it is important to be careful about the issue of fluid depletion during use. If the pump is not used for an extended period after shutdown, the power supply should be cut off periodically, and the internal passages of the pump should be cleaned thoroughly with clean water, paying special attention to the sealing components. If the ambient temperature is very low, the fluid inside the pump chamber must be completely drained to prevent the pump body from cracking due to freezing. Secondly, the pump should be rotated regularly; it is important to do this at least once a week, and the position after rotation should not remain the same as the initial position. For motors, it is important to pay attention to waterproofing and dust protection. Incomplete; it’s just my own opinion.

There are too many moving devices; P. Make sure to maintain them properly when they’re not in use :P

Thank you, thank you for your support. Please help me introduce more business opportunities

Movable equipment is too broad. For the maintenance of small pumps, such as single-stage centrifugal pumps, based on my work experience, I check whether the bearings, seals, and couplings are functioning properly; I also examine the current of the motor (as a auxiliary device), ensure that the bearings are in good condition, and verify that the protective grounding, local switches, and operation indicator lights are not malfunctioning
