Abstract

The invention provides a honeycomb core structure and a turbine honeycomb gland comprising the same. The honeycomb core structure is welded on a connecting plate and comprises multiple honeycomb corrugated tapes; the multiple honeycomb corrugated tapes are arranged at intervals; each honeycomb corrugated tape comprises a main corrugated tape body and a moisture resisting layer; each main corrugated tape body has a moisture resisting end surface, and the main corrugated tape body and another main corrugated tape body located on one side of the main corrugated tape body are arranged at an interval by the aid of the moisture resisting end surface; the moisture resisting layers are arranged on the moisture resisting end surfaces of the main corrugated tape bodies so as to prevent solder from climbing along the gaps between every two adjacent honeycomb corrugated tapes by the aid of the moisture resisting layers when the multiple honeycomb corrugated tapes are welded on the connecting plate. By the aid of the honeycomb core structure, the problem that gaps among honeycomb corrugated tapes are filled with the solder easily during brazing of honeycomb cores in the prior art is solved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a honeycomb core structure and a turbine honeycomb seal with the same. Background technique [0002] When the existing honeycomb air seal used for sealing the turbine is brazed, the honeycomb core and the back plate are brazed with a certain thickness or a certain amount of solder for different honeycomb core grids and honeycomb heights. [0003] However, during the brazing process, the molten solder will automatically fill the gaps between the honeycomb bands with better wettability due to capillary action. This excessive solder filling between the honeycomb bands will cause the honeycomb core to harden, especially the excessive solder between the honeycomb bands will have hard intermetallic compounds. The honeycomb air seal is a key component for sealing in turbomachinery. Due to the hard material produced by the hardened honeycomb core, it will wear the grate teeth or bla...
