Pumps for transporting coal slurry at Shenhua and Yanchang
Thread Content
Some materials state that the high-pressure slurry feed pump used for direct coal-to-oil production at Shenhua is a five-cylinder plunger pump manufactured by the German company URACA. Could someone provide detailed information on the performance of this pump? Also, I wonder which company manufactures the feed pump used for extended kerosene co-refining, and what type it is. Does anyone know?

Just like ordinary reciprocating pumps, it is capable of handling media containing solids. What sets it apart from ordinary pumps is its wear resistance and ability to prevent deposition. There’s no difference in the rest.
It is about understanding how to ensure wear resistance, as well as issues such as whether one-way valves will fail. Everyone is of course familiar with simple plunger pumps, but transporting materials containing solids seems complicated; I hope more information on this topic can be provided.
The main components are typically made of materials with high hardness; the most significant wear occurs in areas with high flow rates and large pressure differences, that is, at the valve seats. Ball valves are used for these valve assemblies, and wear-resistant layers are welded onto the valve seats. There doesn’t seem to be any difference elsewhere
Is the flushing oil the cause of sedimentation prevention and failure of check valves? How to implement it
Three sets of flushing oil systems: injection oil, isolation fluid, and flushing oil. Among them, the isolation fluid technology has the highest level of complexity and is the most critical technical aspect.
Wear is certainly inevitable; both the valve ball and the valve seat experience wear. I’m not an expert in equipment, so I’m sorry; this is all the information I have.
