Pressure issues with the pumps in closed-loop systems!
Thread Content
In a closed-loop system, will the inlet and outlet pressures of the pump keep increasing? There are heaters in the system, the pipelines have a certain length, and there is no gas present. I’m wondering whether, if the circulation continues, the inlet pressure of the pump will increase, and consequently the outlet pressure as well? ? ? But I’ve seen that in many homes with heating systems, it’s a closed-loop system, and after a few years, the pump is still in good condition! ! I’m a bit confused now
If there is no leakage or addition, temperature determines the outlet pressure; as the temperature rises, the pressure increases. If the inlet temperature remains constant, the outlet pressure also remains constant
It’s a loop; the temperature in this loop is 320 degrees. There is a heater that keeps heating the fluid (located near the pump outlet), and there’s also a condenser that cools the fluid (located near the pump inlet). My understanding is that the pressure loss caused by the pump’s pumping action occurs due to resistances such as elbows, and some heat is generated as well. Therefore, the inlet pressure remains more or less the same, and the outlet pressure doesn’t change much either. Is that correct?
Yes, the heat generated causes the temperature to rise, but the condenser reduces this temperature, so the temperature remains constant; as a result, the outlet pressure does not change much either
The pressure after the outlet reaches the inlet via pipes, elbows, heat exchangers, and heaters remains essentially constant; therefore, the system pressure does not increase over time
