The auxiliary sealing device of the suspended semi submersible vertical turbine pump

The auxiliary sealing device of the suspended semi submersible vertical turbine pump and the suspended semi submersible vertical turbine pump. The emergency sealing plate in the auxiliary sealing device is fixed on the pump rotor assembly, and the emergency sealing ring is placed on the sealing flange and cooperates with the emergency sealing plate to block the sealing pump body. The positioning slider is movable and placed inside the sealing flange, and cooperates with the emergency sealing plate to push the emergency sealing plate to move and seal with the emergency sealing ring. The positioning rod is placed on the sealing flange and cooperates with the positioning slider to push the positioning slider to move. When the mechanical seal of the suspended semi submersible vertical turbine pump equipped with this device needs to be repaired or replaced, the auxiliary sealing device is used to isolate and seal the chemicals inside the tank or similar container from the outside, and then carry out subsequent maintenance operations. This technical method can ensure that there will be no leakage of chemical media during pump shutdown or maintenance of the pump equipment.

Technical requirements: 1. Auxiliary sealing device for pumps, characterized in that the sealing device comprises several sealing components, which cooperate with the pump rotor component on the pump and move axially with the pump rotor component to achieve sealing.
