More Information
Summary:The utility model relates to a protection device for a mechanical sealing friction pair, characterized in that one side of the friction surface of the friction pair deviating from the cavity of a pump is provided with an enclosed space which is filled with liquid mediums for lubrication and cooling. The friction surface of the friction pair can work inside liquid phase mediums all the time, transfer heat quantity, and emit heat quantity using the friction surface of the liquid phase mediums for ensuring the pump to run under the condition of evacuation; the friction pair can not be damaged. The protection device of the utility model can be widely used in various rotating shaft machines with mechanical seal.
