Problems with sliding bearings in high-temperature molten salt pumps
Thread Content
This post was last edited by Meng Cheng from Longgang Pump Industry on 2017-1-23 at 13:35. High-temperature molten salt pumps (submersible pumps) can operate at temperatures of 400+ degrees. In the past, copper or ductile iron liners were used for such pumps; depending on the submersion depth, the service life varied – around 1 year for depths of 3 meters, with some lasting up to 2 years. I would like to ask now: are there any better materials that are more heat-resistant, wear-resistant, and impact-resistant that can be used as substitutes for shaft linings in high-temperature molten salts?
There should be some; please have an expert answer
Where are the experts? Please help out!
Ceramics can indeed withstand high-temperature molten salts, but they have poor impact resistance! It works well for now, but I want to go further!
Are you referring to the copper material, and would you like to increase the serial number?
What specific material would you like to ask about? Pump body? Bearings? Bushing?
A submerged sliding bearing is nothing but a bushing
