The circulating water heat exchanger experiences significant vibration
Thread Content
Due to the good heat exchange efficiency, energy savings and reduced consumption can be achieved by reducing the return valve flow rate of the circulating water heater. However, after reducing the outlet valve, the vibration in the flow restriction pipeline becomes quite significant; what is the best way to address this issue?
If the circulating water heat exchanger vibrates severely, it can be inspected and addressed from the following aspects: 1. Check whether the water pump is operating properly; if the pump does not function correctly, it may cause unstable water flow in the pipes, thereby leading to vibrations in the heat exchanger. 2. Check whether there is any damage to the circulating water heat exchanger itself; if there is damage, it should be repaired or replaced as soon as possible. 3. Check whether the circulating water heat exchanger is installed stably; if it is not installed stably, it may also cause vibration of the heat exchanger. 4. Avoid closing too many valves. The closing of the circulating water return valve should be moderate; excessive closing may result in a high flow velocity and significant vibration. 5. Dampers can also be installed on the pipeline or additional fixing brackets can be added to reduce vibrations. 6. If the above methods do not solve the problem, it may be necessary to hire a professional for inspection and repair. .
If it is caused by flow velocity, the vibration factor needs to be taken into consideration. Moreover, one cannot focus solely on energy savings while ignoring vibration factors, as vibration can cause pipes to fatigue and break. Let’s see if vibrations can be eliminated by adjusting temperature and pressure; it’s worth giving it a try.
It’s likely that the design is inherently tight; don’t go to such extreme measures
