Abstract
The invention discloses a vertical pump relating to a pump. A pump body is internally provided with an impeller above which a sealed cavity is arranged; the sealed cavity is internally provided with a mechanical seal; the top of the sealed cavity is provided with a vent valve; when water is added into the pump, the vent valve is opened for air exhaust; after the water pump works, liquid sufficiently contacts with the mechanical seal to cool and lubricate the mechanical seal, thereby avoiding causing damage due to dry friction. The invention is suitable for the vertical pump.
Description
Technical field
The present invention relates to the pump class, say it is a kind of vertical pump in detail.
Background technique
We know that existing vertical pump is provided with impeller in the pump housing, the impeller top is provided with Seal cage, is provided with mechanical seal in the Seal cage, this vertical pump, because the impeller top is provided with Seal cage, be provided with mechanical seal in the Seal cage, when adding water in the pump housing, the gas in the Seal cage can't be discharged, behind pump working, liquid can't contact mechanical seal, and mechanical seal can not get cooling and lubricated, causes dry friction to damage.
Summary of the invention
The technical problem that the present invention solves is, solve liquid and can't contact mechanical seal, mechanical seal can not get cooling and lubricated, the problem that causes dry friction to damage, provide a kind of liquid that can make fully to contact mechanical seal, mechanical seal is cooled off and lubricated, avoid the vertical pump that causes dry friction to damage.
Technological scheme of the present invention is, is provided with impeller in the pump housing, and the impeller top is provided with Seal cage, is provided with mechanical seal in the Seal cage, and the main structure characteristics are that the Seal cage top is provided with outlet valve.
The invention has the beneficial effects as follows that because the Seal cage top is provided with outlet valve, when adding water in the pump housing, opens outlet valve gas is discharged, behind pump working, liquid fully contacts mechanical seal, and mechanical seal is cooled off and lubricated, avoid causing dry friction to damage.The present invention is applicable to vertical pump.
Description of drawings
Accompanying drawing is a kind of structural representation of the present invention, also is a kind of embodiment's schematic representation.
Embodiment
Vertical pump as shown in the figure, be provided with impeller 5 in the pump housing 1, impeller 5 tops are provided with Seal cage 4, are provided with mechanical seal 3 in the Seal cage 4, Seal cage 4 tops are provided with outlet valve 2, because Seal cage 4 tops are provided with outlet valve 2, when adding water in the pump housing 1, open outlet valve 2 gas is discharged, behind pump working, liquid fully contacts mechanical seal 3, and mechanical seal 3 is cooled off and lubricated, and avoids causing dry friction to damage.
