Kettle seal issues
Thread Content
What is the typical pressure of the flushing water at the kettle-type mechanical seal? What is the relationship between this pressure and the pressure inside the kettle? If the flushing pressure is too high, will it have an impact on the mechanical seal? Oh God, please show me the way
Are you sure this water is for rinsing or cooling?
Reply to 1# zhong127: The pressure of the flushing water (sealing water) for conventional mechanical seals should be 0.1–0.2 MP higher than the pressure inside the tank, in order to prevent the medium from leaking into the flushing water system
Under normal circumstances, the pressure of the cooling water or flushing water is usually 1-2 KG higher than the pressure of the medium; the circulating cooling water enters and exits, enabling circulation within the mechanical seal. The flushing hole is generally a separate hole that directly flushes the sealing surface at the medium side. By ‘boiler’ you probably mean water injection inside the boiler, along with a mechanical seal equipped with a flushing medium to prevent the medium from accumulating and blocking the rotating and stationary rings at that end. Under normal circumstances, this type of kettle cannot have its power cut off or stopped from operating, as doing so will cause the mechanical seal to get clogged. This is the case, for example, with the 108-cubic-meter polymerization reactor used by Beihua Machinery, which features German Börgmann seal assemblies. However, the machine seal coolant is circulated using an oil station.
