Water discharge device for marine suspended semi submersible vertical turbine pump

The water discharge device for marine suspended semi submersible vertical turbine pumps belongs to the field of pump water discharge structure manufacturing. It is characterized in that a discharge port (7) is opened between the suction chamber (9) and the discharge chamber (8) of the pump, and a hole coaxial with the axis of the discharge port (7) is opened on the pump body (1), which is threaded with the discharge plug body (2) and equipped with a sealing ring (4) and a sealing ring blocking ring (5). The connection between the suction chamber (9) and the discharge chamber (8) is controlled by the drain bolt (3), and the degree of loosening of the drain bolt (3) is controlled by the stop ring (6). When the drain bolt (3) connected to the drain port (7) is tightened, the bolt head blocks the drain port (7), and the suction chamber (9) and the discharge chamber (8) are closed; When the drain bolt (3) connected to the drain port (7) is loosened or the drain port (7) is rotated out, the suction chamber (9) and the outlet chamber (8) are connected, and the water in the high-pressure chamber flows into the low-pressure chamber.

Technical requirements: 1. A water discharge device for a marine suspended semi submersible vertical turbine pump, characterized in that a water discharge port (7) is opened between the suction chamber (9) and the discharge chamber (8), and a hole coaxial with the axis of the water discharge port (7) is opened on the pump body (1), which is threaded with the water discharge plug body (2) and equipped with a sealing ring (4) and a sealing ring stopper ring (5). The connection between the suction chamber (9) and the discharge chamber (8) is controlled by a water discharge bolt (3).
