Abstract

The invention discloses a stator assembly and a stator ring processing method for a hydraulic dynamometer. The stator assembly is in the shape of a hollow cylinder, and includes unloading rings and stator ring groups arranged alternately along the axial direction and against each other, and the stator ring The group is arranged between two adjacent unloading rings. The unloading ring is an integral ring structure. The stator ring set includes a first stator ring and a second stator ring that are spliced ​​opposite to each other. Both the first stator ring and the second stator ring are ring structures, and the first stator ring and the second stator ring are horizontal along the center line Face half split setting. The structural setting of the stator assembly used in the hydraulic dynamometer of the present invention not only makes the structure of the stator assembly simple, the layout is compact, and the required installation space is small, but also the unloading ring and the stator ring group are arranged alternately in the axial direction, so that the stator The water flow in the module is more uniform, the test effect is better, and the test result is more accurate.

Description

technical field [0001] The invention relates to the field of hydraulic dynamometers, in particular to a stator assembly of a hydraulic dynamometer. In addition, the present invention also relates to a method for processing the stator ring in the stator assembly of the hydraulic dynamometer. Background technique [0002] In the hydraulic dynamometer equipment, the stator assembly is responsible for the function of water flow and work in a closed environment, and is an important component. The stator assembly generally appears in the occasion of medium power and high speed hydraulic dynamometer equipment. The stator ring in the stator assembly generally has a large area and thin wall, and the material has good thermal conductivity. [0003] In the prior art, the stator ring mainly adopts an integral form, which makes it very inconvenient to assemble and disassemble the stator assembly and the rotor assembly, and during the installation process, the positioning operation is di...
