How should centrifugal pumps that are not in use outdoors be properly protected?
Thread Content
Gentle experts, I’m new to equipment management and have already run into a problem! Our facility has several centrifugal pumps that are no longer in use; they have been outside for a long time and are covered in rust, creating a very poor condition at that location. I plan to start improving equipment management by focusing on these outdoor pumps that are currently not in use. But I don’t know where to start; please give me some advice!
Wrap it in plastic sheeting to prevent corrosion, pay attention to hygiene, rotate the shaft frequently, drain the medium, and if possible, use nitrogen for protection.
Paint the pump body and motor, fill them with oil, and perform regular turning operations
For units that have to stop using centrifugal pumps for treatment due to process-related reasons, the following recommendations are given: 1. For aesthetic reasons, it is possible to remove rust, paint the units, apply lubricant, and rotate the shafts to keep them in a ready state; 2. Again for aesthetic reasons, it is possible to disassemble the units, repair them, remove rust, paint them, apply lubricant, pack them up, put them in boxes, and store them
Thank you all for your suggestions! ! Thank you very much
1. Apply anti-corrosion paint to maintain aesthetics; this is a must for 5S in the workplace； 2. Regularly turn the shaft and apply oil ； 3. Keep the pump in a standby state, which is useful for emergency handling; although it’s not clear what purpose your centrifugal pump serves
Pump------running idle, dry running. It is recommended to install an anti-idle protection device for the pump, which will shut it down automatically within 2 seconds when idling, thereby protecting the pump from damage. Electronic sample available at: http://www.dnpump.com/PicUp/200910162202501.pdf If you want to minimize maintenance efforts, it’s better to use a built-in anti-idle protection device – it saves time
Ensure proper anti-corrosion measures, maintain hygiene, regularly turn the shaft, drain the medium, and if possible, use nitrogen for protection
