Problems solved by technology

[0003] The purpose of the present invention is to provide an assembly process for the stator shielding sleeve of a large shielded motor, which solves the problem of handling, processing and installation of the large shielding sleeve due to the small assembly gap and the thin wall of the shielding sleeve, which will cause the shielding sleeve to be squeezed, deformed, and bumped. Damaged, resulting in the problem that it cannot be installed, and the shielding sleeve can be installed in place at one time without reprocessing, reducing the risk of assembly

Embodiment Construction

[0020] Such as Figure 4 As shown, a large-scale shielded motor stator shielding sleeve assembly process uses a precision measuring micrometer 1, a shielding sleeve tire expansion 2, a shielding sleeve assembly guide tool 3, a crane 4, and a limit stop 5 to carry out assembly. The method includes the following step:

[0021] a) if figure 1 As shown, use a precision measuring micrometer 1 to measure the distance between the weld bevel 8 of the shield sleeve ring at the upper end of the stator and the weld bevel 9 of the shield sleeve ring at the lower end of the stator, that is, the theoretical length of the shield sleeve, measured when the stator is placed horizontally, Always keep the precision measuring micrometer in a horizontal state, rotate the stator to measure 4 places evenly and take the average value;

[0022] b) if figure 2 As shown, install the shielding sleeve expansion tire 2 into the shielding sleeve 6, and tighten the shielding sleeve by tightening the screw...

Abstract

The invention relates to an assembling process for a large shielding motor stator shielding sleeve and a stator. Measuring the distance between the two ends of the stator and a welding groove of the shielding sleeve by using a precise measuring micrometer; installing a shielding sleeve expansion tire to an inner hole of the shielding sleeve and expanding the shielding sleeve; processing the shielding sleeve and the expansion tire to a required length together; installing a shielding sleeve assembling guide tool to the upper end of the stator; and hoisting the shielding sleeve expansion tire and the shielding sleeve by using a crane. One-time installation in place is realized, the problems that the large shielding sleeve is small in carrying, machining and assembling gap, and the shieldingsleeve thin-wall part is extruded, deformed, collided and damaged in the installation process, so that the shielding sleeve cannot be installed are solved, and the assembly quality of the stator shielding sleeve and the performance of a shielding motor are guaranteed.

Description

Technical field: [0001] The invention relates to a large-scale shielded motor stator shielding sleeve and stator assembly process. Background technique: [0002] With the development and application of nuclear power technology, the safety of nuclear power plants has been continuously improved and improved, and large canned motor pumps will be widely used. The motor stator shielding sleeve and the stator of this shielded motor pump are assembled at room temperature, and the assembly diameter gap is very small, 0.40-0.70mm. The diameter of the shielding sleeve is about Φ600mm, the length is about 3800mm, and the wall thickness is about 0.40mm. Larger dimensions, thinner wall thickness, out-of-round shape, very small assembly clearance, and the inner surface of the shielded motor structure is composed of stator core, upper and lower support rings, upper and lower shielding sleeve friction surfaces, not The continuous smooth surface makes the assembly of the stator shielding s...
