Can the high-temperature water circulation pump be stopped directly when the factory is shut down?
Thread Content
Our factory has a circulation pump that enables self-circulation of water at 200 degrees under pressure. Is it possible to stop the pump directly while under 200 degrees pressure during normal shutdown? Are there any relevant regulations? Some colleagues said that scaling can form on the surface of the pump during water cooling.
It can be stopped; after shutting down the pump, the medium inside it just needs to be emptied as soon as possible
Of course, it can be stopped directly. Whether scaling occurs depends mainly on the water quality; if it’s not deionized water, scaling will still happen during normal operation.
I’m confused. If we can’t just stop the pump directly, then how else can we do it? Do we have to replace all the water in the entire system before stopping it? That’s ridiculous!
Whether to stop the pump or not depends on your process conditions. If the water is used as a cooling medium, it’s better not to stop it. One way to determine this is that important equipment usually has interlock protection devices; they will stop operating on their own if the pump is stopped, thus maintaining a safe condition at all times.
