Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0035] Figure 2A to Figure 2C It is a structural schematic diagram of the honeycomb seal in the embodiment of the present invention. in, Figure 2A main view, Figure 2B for Figure 2A The enlarged view of the cross-sectional view of I-I in the middle, Figure 2C It is a partial enlarged view of the honeycomb belt. Such as Figure 2A to Figure 2C As shown, the honeycomb seal 20 includes: at least one honeycomb belt portion 21 ( Figure 2A and Figure 2B Take the case of three honeycomb belt parts 21 as an example) and a base part 22.

[0036] Wherein, each honeycomb belt portion 21 has a plurality of integrally formed small honeycomb holes 211 . Integral molding in this embodiment means that the small honeycomb holes 211 are no longer welded by two parts, but formed at one time...

Abstract

The invention discloses a honeycomb seal and its manufacturing method and system, wherein the honeycomb seal comprises: at least one honeycomb belt part, each honeycomb belt part has a plurality of integrally formed small honeycomb holes; It is arranged on one side of the honeycomb belt part and seals one end of the small honeycomb hole. The technical solution in the embodiment of the present invention can simplify the processing process of the honeycomb seal and reduce the production cost.

Description

technical field [0001] The invention relates to the field of product manufacturing, in particular to a honeycomb seal and a method and system for manufacturing the honeycomb seal. Background technique [0002] Seals are materials or parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the internal parts of the machine. For example, seals are widely used in turbomachinery to reduce leakage losses between the rotor and stator to improve aerodynamic efficiency. [0003] At present, the eddy current mechanism usually adopts a labyrinth seal. Labyrinth seal refers to the arrangement of a number of annular sealing teeth arranged in sequence around the rotating shaft. A series of interception gaps and expansion cavities are formed between the teeth. the goal of. In order to avoid possible damage to the labyrinth seal teeth due to collision with the rotor, a large enough space...
