Reasons and solutions for mechanical seal failure of hot oil pump

The high temperature of the hot oil pump is the main cause of mechanical seal failure, which vaporizes the medium inside the sealing end face; High temperature causes a decrease in the performance of graphite rings; High temperature causes scaling of cooling water; High temperature causes the tungsten carbide ring of the hot pack to loosen; Due to high temperature, the hot oil pump is prone to evacuation, causing defects such as static ring displacement and dynamic ring sealing ring flanging. When impurities are present, they can also exacerbate the wear of the sealing surface.
