Double-stator driven power unit integrated spiral mixed-flow type water jet propulsion pump

Abstract

The invention discloses a double-stator driven power unit integrated spiral mixed-flow type water jet propulsion pump. The invention relates to the technical field of water jet propulsion, a magneticsuspension bearing is composed of a first magnet and a second magnet, the first magnet is embedded and fixed on the inner wall of a shell at two ends of a winding coil, the second magnet is fixed at two ends of a permanent magnet, and the first magnet and the second magnet at the same end are arranged in a homopolar repulsion manner; wherein one end of the shell is a water body inlet, a rectification spray pipe is integrally formed at the other end, a plurality of guide vane blades are integrally formed on the inner wall of the rectification spray pipe, a guide device is arranged in the rectification spray pipe, and a water body outlet is formed at the other end of the rectification spray pipe; and a fixed bracket is arranged in the shell in the water body inlet. And the electric energy conversion rate is high, the propulsion efficiency and the damage pipe redundancy of the submarine are improved, the space in the naval vessel is effectively saved, and the radiation noise is effectively shielded and reduced.

Description

technical field [0001] The invention relates to the technical field of water jet propulsion, in particular to a helical mixed-flow water jet propulsion pump with integrated power unit driven by double stators. Background technique [0002] The water jet propulsion pump for ships and amphibious vehicles refers to the energy conversion device for the thrust required by ships or amphibious vehicles to travel in water. The ship moves. There are many types of marine propulsion pumps. According to the propulsion principle, they are divided into propellers, water jet propulsion pumps, and special propulsion pumps. The propeller is the main propulsion device of the ship at present. Its principle is that when the propeller rotates, the blades continuously push a large amount of water backwards, and a forward force is generated on the blades, that is, the propulsion force. The propeller blade is like a small section of wing, and the component force of the hydrodynamic force on the b...
