Selection of liquid argon loading pumps
Thread Content
There is currently one 100-cubic-meter liquid argon storage tank, and an additional pump for loading liquid argon is needed; it is not possible to determine which type of pump to use – centrifugal or piston? And the parameters of the pump (flow rate, head, etc.; it would be best to provide a pump data sheet: lol). And what are the precautions regarding piping (is there also a return line or something? ) I hope the experts will kindly offer their guidance! :lol
If you don’t even know basic data such as temperature, viscosity, pressure, etc., how can you choose a PI pump!
The ones upstairs aren’t reliable; the original poster explained it clearly. Does the original poster have any other cryogenic liquid centrifugal pumps? Here, we rely on the static pressure of the tanks for loading – during loading, the pipes are emptied to maintain a slight positive pressure. We’re also planning to install an additional filling pump to improve loading efficiency. In fact, both liquid nitrogen and liquid oxygen here are handled using CryoStar centrifugal pumps. However, with 100-cubic-meter storage tanks, the gas space at the top is relatively small, and gaseous argon is recovered and reused, which affects the pressure at the top and thus the conditions related to argon. I’m not sure whether the original poster’s liquid argon tank is independent or part of a shared setup. If it’s independent, I think a centrifugal pump is sufficient; a return line is definitely necessary. Additionally, an inverter-driven motor can be installed to ensure more stable operation
To avoid loading losses and the impact on the argon system, it is possible to stop feeding argon back into the pure argon column during filling~~ Of course, if waste is not a concern and pre-cooling is carried out without enabling the reflux pump, then the impact of argon feedback on the pure argon column will be reduced~~
Tell the manufacturer of the pump what you need~~have them help you choose the right model; there are imported options like ACD and Cryostar, as well as domestic ones from Hangzhou Xinya~~
Liquid argon loading pump, centrifugal type, 380V, 29.4A, 15KW, 50HZ; motor speed: 2930 rpm, flow rate: 15 m³/h; pump speed: 4900 rpm, head: 80 m, produced by Sichuan Air Separation
It’s sufficient to use domestic pump units for flushing; there is no need to opt for imported equipment.
Thank you. You can’t have both the fish and the bear’s paws; there’s nothing to do about it – conditions must come first
Then start the pump – the check valve won’t move~~ Hehe~~
Many domestic loading pumps are equipped with components from Hangzhou Xinya; you can look up their phone numbers online and get in touch with them – their engineers will help you sort it out.
