Marine electromagnetic shaftless rim water spray pump

Abstract

The invention discloses a marine electromagnetic flangeless wheel water spray pump, which comprises: a water spray pump, a stator part, a rotor part and a bearing assembly; wherein, the water spray pump includes a shell, and water outlets and water inlets arranged at both ends of the shell; the stator The component and the rotor component are arranged on the housing near the water outlet; the stator component is an annular structure, the rotor component is arranged in the ring of the stator component, and the stator component and the rotor component are connected to each other through a bearing assembly; the stator component is provided with a motor Coil windings, rotor rings, permanent magnets and paddles are arranged inside the rotor parts; the motor coil windings inside the stator parts are energized to generate a rotating magnetic field, and the permanent magnets drive the rotor ring to rotate under the action of the rotating magnetic field, and the blades are connected to the rotor ring to rotate And generate thrust to push the ship forward. While effectively improving the propulsion efficiency, the present invention greatly reduces the probability of aquatic plants and other sundries being entangled or even damaged the pump shaft, thereby ensuring the safety of the ship.

Description

technical field [0001] The invention relates to the technical field of ship propulsion pumps, in particular to a marine electromagnetic water jet pump without flanges. Background technique [0002] As the performance requirements of marine propulsion devices are getting higher and higher, the traditional shaft drive has many components, the cabin occupies a large space, the energy loss is large, and the vibration and noise of the shafting are difficult to control. Especially for compact ships such as boats and submarines, the cabin space is limited, and high maneuverability and stable and reliable shafting are required. The water jet pump has a series of advantages such as small radius of gyration, low noise and vibration in the ship cabin, and simple structure. Therefore, water jet pumps are widely used in compact ships such as submarines and yachts. Most of the existing water jet pumps are driven by the pump shaft. When the pump shaft rotates, vibration and noise are sti...
