A minor issue with the high-temperature water pump
Thread Content
High-temperature water pumps all have cooling water. What happens if there isn’t enough cooling water? What does the sound of cavitation sound like? I’m seeking advice from everyone. Today, I heard a high-pitched screeching sound coming from a boiler feed pump while it was in operation; it didn’t seem to be coming from the bearings. The temperature of the water flowing from the deaerator to the feed pump is estimated to be around 100 degrees. The boiler was in the heating phase, and the cooling pipes of the feed pump weren’t properly connected – temporary hoses were used instead, and those hoses became flattened due to the high water temperature. This might mean there isn’t enough cooling water. I’m not very familiar with these pumps, so I hope to get some insights. Thank you!
A lack of cooling water leads to high temperatures in the bearing housing; if the bearings become too hot, a whistling sound can be heard and the pump may stop working immediately. Cavitation, along with vibration and whistling, can also cause these problems, and the same phenomena occur when the pump operates at too low a flow rate
