The invention discloses an immersed hydraulic ballast pump, and belongs to the technical field of ballast pumps. A water inlet and a water outlet are formed in the two sides of a pump shell of the immersed hydraulic ballast pump, a motor shell and a flow guide shell are fixedly arranged in the pump shell, a motor opening is formed in the bottom end of the motor shell, a hydraulic motor output end of the motor shell is connected with a pump shaft, the pump shaft penetrates the motor opening, the pump shaft and the motor opening are arranged in a seal manner, the portion, penetrating the motor opening, of the pump shaft is fixedly sleeved with an impeller, and the impeller is arranged in the flow guide shell; the interior of the motor shell is filled with liquid media, a monitoring device of the immersed hydraulic ballast pump comprises a monitoring pipe and an observation cavity formed in the outer portion of the pump shell, and the two ends of the monitoring pipe are communicated with the motor shell and the observation cavity; the failure seal portion can be rapidly determined, maintaining of the immersed hydraulic ballast pump is facilitated, and the immersed hydraulic ballast pump can normally run as soon as possible.
Description
technical field [0001] The invention belongs to the technical field of ballast pumps, in particular to a submersible hydraulic ballast pump. Background technique [0002] The submersible hydraulic load pump is the most important and critical core equipment in the marine ballast system. Its main function is to complete the injection and discharge of water, so as to achieve the following purposes: adjust the draft of the ship and the stability and safety of the longitudinal and lateral hull The metacentric height; reduce the deformation of the hull, so as not to cause excessive bending moment and shear moment, reduce the vibration of the hull; improve the seaworthiness of the empty cabin. [0003] In the prior art, the submersible hydraulic load pump usually includes a pump casing and a motor casing coaxially arranged in the pump casing. A hydraulic motor is arranged in the motor casing. The output end of the hydraulic motor is connected to the pump shaft. An impeller is prov...
