As for which specific equipment and pipelines, we specialize in this process. By pump clogging, do you mean the seal? Is it the pipeline from the filtration system?
Pump impeller flow channel, pump inlet and outlet pipelines. Prone to congestion. Circulating solutions can also get clogged sometimes.
By flow channel, you mean the suction tube used for sealing and cooling, right? The blockage at the pump’s inlet and outlet is definitely due to the lack of liquid flow over a long period of time; the blockage in the circulating solution is a problem related to the process design.
During operation, the impeller gets caked into balls by sulfur; each time it gets blocked, the pump has to be disassembled for cleaning.
You’re using 304L for the impellers, right? What are the pump’s flow rate and speed parameters? It shouldn’t get clogged – the pumps we use to produce sulfur slurry 24 hours a day have never suffered from clogging; there might be some deposits inside the pump head, but it’s not serious, and the pumps remain functional; we’ve never encountered any issues that would prevent them from operating.
Impeller: ZG1Cr18Ni12Mo2Ti, closed type. Normal flow rate: 11 m³/h; rated flow rate: 13.3 m³/h; minimum continuous flow rate: 4 m³/h. Head: 37.5 m. Rotational speed: 2950 r/min
There’s a problem with the selection; let’s discuss it in detail via QQ
Study*Study*! :lol:lol:lol
Pump parameters: Flow rate: 13.3 m3/h, Head: 37.5 m, Power: 7.5 KW, Speed: 2900 r/min
Is it the hafnium-iron process? ? ?
