What device is this? Take a look at the picture and guess
It also looks like a centrifugal pump, but with these proportions, it’s just hhl
This type of import/export design should be a rotary jet pump.
It’s a bit like a sea lion-type rotary vane pump; it is characterized by low flow rates but high head, and is said to be able to replace multi-stage pumps and high-speed pumps； It sounds quite impressive, but in reality high requirements are placed on the medium used; it must be a clean medium at the very least. However, in applications involving several cubic meters and hundreds of meters of length, its advantages are evident – as friction losses are reduced, its efficiency is 10 to 20 percentage points higher than that of conventional pumps, and in some cases even over 30 percentage points higher
I’m not very familiar with it, but it seems to be a bit poorly processed\ud83d\ude02
There are many experienced experts out there. It seems to be a rough pump head of a rotary casing pump that was acquired from another manufacturer; they test it themselves and then ship it after applying paint, haha
It seems this sea friend has used a spiral shell pump; I wonder what the performance of such a pump is like? What kind of failures are likely to occur?
I am a designer of rotary vane pumps············· We call them pitot tube pumps; they offer better stability compared to multi-stage pumps and high-speed pumps, but their range of applications is not as wide as that of multi-stage pumps. However, whenever the medium contains impurities, no pump will function properly anyway
