The invention relates to a compact marine water cannon booster centrifugal pump which is used for solving the problems that a conventional centrifugal pump is not compact in overall structure, long in axial size, large in number of parts, heavy in weight and inconvenient to install and maintain. The pump comprises a left pump cover, a water-lubricated guide bearing component, a pump body and a right pump cover, a pumping chamber is arranged in the pump body, and the left pump cover and the right pump cover are installed on the pump body and form a water suction chamber. The water suction chamber is communicated with the pumping chamber through an impeller mounting cavity, an impeller is mounted in the impeller mounting cavity, and the impeller is fixed on a shaft; the shaft sleeve is sleeved on the shaft, is fixed through a first key in the radial direction and is fixed through a round nut in the axial direction; a non-driving end gland is arranged at the tail end of the non-driving end of the shaft, and a cavity is formed between the non-driving end gland and the end face of the shaft; and the outer surface of the water-lubricated guide bearing component is connected with the left pump cover, and the side surface of the water-lubricated guide bearing component is connected with the non-driving end gland. A symmetrical hydraulic structure is adopted, and the equipment operation stability is high.
Description
technical field [0001] The invention relates to the field of marine centrifugal pumps, in particular to a compact marine water cannon booster centrifugal pump. Background technique [0002] Marine water cannon booster centrifugal pump, installed at the bottom of the cabin, is driven by the hull power system or other driving equipment to pressurize the liquid. The pressurized liquid enters the water cannon base through valves and pipes, and is formed after rectification and energy conversion of the gun tube. High-speed water jets. The water cannon supercharged centrifugal pump can be used with the long-range water cannon on the coast guard ship to improve the defense capability of the coast guard and ensure the safety of the ship's navigation. It can be used in conjunction with fire boats to enhance the fire fighting capabilities of ships. [0003] The existing marine water cannon booster pump generally has two structural types of centrifugal pump products: [0004] One ty...
