Submersible sand-proof permanent magnet synchronous energy-saving motor

Abstract

The invention discloses a submersible sand-proof permanent magnet synchronous energy-saving motor. The motor comprises a permanent magnet rotor, a stator is arranged on the circumference of the permanent magnet rotor, and a rotor permanent magnet conducting bar is arranged between the rotor and the stator. A bearing is connected to the top of the permanent magnet rotor, and a thrust sliding bearing connected to the bottom of the permanent magnet rotor. The bearing is positioned on an upper guide bearing seat. The thrust sliding bearing is located on a lower guide bearing seat. Waterproof coils are arranged on the outer sides of the upper guide bearing seat and the lower guide bearing seat respectively, the waterproof coils are connected with the stator, and the tops of the waterproof coils are connected with leads. A coupling seat is arranged at the top of the upper guide bearing seat, and a coupler is mounted in the center of the coupling seat. A sand-proof cover and four sealing structures are installed between the coupler and the upper thrust sliding bearing from top to bottom. A sliding thrust disc is connected to the bottom of the thrust sliding bearing, and a base is arranged at the bottom of the sliding thrust disc. The problems that silt cannot be separated and resources are wasted in the prior art are solved. The motor is energy-saving and sand-proof.

Description

technical field [0001] The invention relates to an electric motor, in particular to a submersible sand prevention permanent magnet synchronous energy-saving electric motor. Background technique [0002] In terms of manufacturing, we will use informatization, technology, and strengthen industrial basic capabilities to improve the level of technology and production quality, and promote intelligent manufacturing and green manufacturing. Due to the unstable speed of the three-phase asynchronous motor, it has strict requirements on the voltage level (required within ±5%) and consumes more power than the permanent magnet synchronous motor. Due to the relatively high cost of power generation in China at present, submersible pumps consume a large amount of electricity every year, deep wells and rivers contain sediment, and the existing permanent magnet motors cannot separate the sediment, so energy saving and service life cannot be achieved.
