After reducing the frequency of the molten salt submersible pump to 45%, how is the flow rate calculated?
Thread Content
If a submersible pump in a molten salt system is equipped with variable frequency equipment, and the frequency is reduced to 50% in order to lower the flow rate of the molten salt, how can one calculate the flow rate of the molten salt within the pipes as well as the head at the pump outlet under such conditions? There are no flow meters, pressure gauges, or other instruments on the pipeline. This submersible pump has an original head of 40m and a flow rate of 10m3/h
You can ask Jiangsu Jingjiang Jinlin Chemical Machinery Factory.
The original head is 40 m, and the flow rate is 10 m3/h. If the speed is reduced by 50% using variable frequency speed control, then the parameters after the speed reduction are: head of 10 m, and flow rate of 5 m3/h. The above are the calculated performance parameters for molten salt pumps; the actual parameters of such pumps depend on the molten salt system in use. Jinan Huawei Pump Co., Ltd. specializes in the production of molten salt pump products; for more information, please visit www.hwpump.com.
The answer above is not correct; the original value for Yang Cheng is 40, and after frequency conversion, it should be 15 instead
You’re wrong on the 4th floor. After frequency conversion, the value, that is, the head, is 10 m3/h; you said it’s 15. You must be calculating based on the density of water.
Give the calculation process so they can learn too
What is the operating temperature of your molten salt, and what type of gaskets are used? .
We use metal wound gaskets with inner and outer reinforcing rings.
