Seasonal differences in domestic pump selection
Thread Content
Since in actual operation, domestic pumps cannot reach the rated displacement due to the temperature rising too fast and exceeding the temperature warning line, which is especially obvious in summer. Is it necessary to increase the pump type to a higher level in the design for this problem? However, the efficiency of the rear pump is too low after being improved. Is there a good solution to this contradiction?
Use auxiliary cooling methods, such as installing a cooling jacket. Can you introduce the industrial and mining conditions used by the equipment and the medium transported, so that everyone can understand the situation in more detail.
The material pumped is liquid, not gas. When the temperature is high in summer, the density of the material will become smaller, but generally the difference will not be greater than 5%. It is still necessary to leave 5% margin in your pump selection, which will not cause the efficiency of the pump to drop much. Moreover, in actual operation, the working conditions fluctuate and change, and a certain margin should be considered. If you feel that the efficiency of the pump will decrease after properly selecting the pump and leaving room for selection, you can spend some more investment and add a frequency conversion device, and there will be no problem.
