Novel low temperature rising water-cooling stator engine base and welding method thereof

Abstract

The invention relates to a novel low temperature rising water-cooling stator engine base and a welding method thereof. The novel low temperature rising water-cooling stator engine base comprises an outer cylinder, a middle cylinder, an inner cylinder and a machine leg component, wherein the length of the inner cylinder is the same as the length of a water-cooling stator and is less than the length of the outer cylinder; the welding method comprises the following steps of: positioning water channel ribs through a rib plate positioning die in sequence and fixing the water channel ribs in a spot welding mode; finding out the position of a blocked weld joint through a blocked weld joint template corresponding to a plurality of water channel ribs; positioning and welding the water channel ribs; and finding blocked weld joints corresponding to the water channel ribs. The welding method is accomplished through the rib plate positioning die and the blocked weld joint template, the error in line drawing positioning and aligning is effectively avoided, the following welding quality is improved, and the cooling performance of the engine base is ensured.

Description

technical field [0001] The invention relates to the field of generators, in particular to a novel low-temperature rising water-cooled stator frame and its welding method, which is especially suitable for stator frames of high-power motors and generators. Background technique [0002] In the development history of wind power technology, weight reduction and vibration reduction are eternal topics. The greater the weight, the greater the pressure on the overall wind tower, and vibration at this time will be fatal, so improving the structure and reducing the weight is imminent. Most of the current wind turbines are composed of two parts, the motor and the cooler. This combination is fixed and bulky, and takes up a lot of space in the wind tower nacelle. Relatively speaking, the nacelle must be enlarged to accommodate Into the cooler, the cooler and the stator are combined into a low-temperature water-cooled stator base, which is used by many manufacturers of the motor base. The...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the shortcomings of the existing technology that the inner cylinder of the stator frame is directly welded to the flange, the vibration is large, the weight is heavy, and the welding process of the channel rib is complicated, the cumulative error is large, the welding quality is poor, the service life is low, and it is not conducive to cooling. The invention provides A new low-temperature rising water-cooled stator base with simple structure, compact structure, light weight and low vibration has been developed. The welding method is simple, which can effectively avoid cumulative errors, improve welding quality and service life, and ensure sufficient cooling
