Abstract
The utility model provides a contact type honeycomb sealing structural body used for sealing of a turbine motor. The structure is that a groove is arranged in the middle of a honeycomb gland sealing matrix ring, and a spring and an inner ring are installed in the groove. The contact type honeycomb sealing structural body is capable of shortening the radial gap between a rotor and a stator, and the inner ring with the spring and self-lubricating performance are added in the middle of the gland sealing matrix ring, so that the structural body is good in sealing performance. The structural body is suitable for serving as a sealing part between the rotor and the stator of the turbine motor.
Description
Technical field
The utility model provides the employed contact-type honeycomb seal structure of turbine engine field of sealing technology body.
Background technique
Vapour or the hermetic seal used on the existing turbine engine are the labyrinth seal structure, and have big gap between the rotor, gas leakage easily, thus the turbine unit efficiency is reduced.
Summary of the invention
In order to overcome the shortcoming of existing turbine engine sealing configuration, the utility model provides contact-type honeycomb seal structure body.This structure solves the technical problem that seals between turbine engine stator and the rotor through in Honeycomb steam seal parent ring, pack into spring and interior ring.
The scheme that the utility model technical solution problem is adopted is: in the middle of Honeycomb steam seal parent ring, be provided with groove, spring and interior ring are housed in groove.
Good effect, the utility model can dwindle rotor and stator radial clearance, and in the middle of packing parent ring, install the interior ring that has spring and self-lubricating property, good seal performance additional.Suit between turbine rotor and stator, to use as sealed member.
Description of drawings
Fig. 1 is a contact-type honeycomb seal structure body sectional structure chart
Fig. 2 is a contact-type honeycomb seal structure body plan structure schematic representation
Among the figure, 1. Honeycomb steam seal parent ring, 2. groove, 3. spring, 4. in ring.
Embodiment
Shown in figure, in the middle of Honeycomb steam seal parent ring 1, be provided with groove 2, spring 3 and interior ring 4 are housed in groove.
Interior ring adopts self lubricating material to process, because the spring force effect with the wear-resisting effect of interior ring, makes interior ring reduce with the between centers crack, thereby lump together throttling of Honeycomb steam seal vortex and the little gap of JC formula packing throttle butterfly that sealing effect is more remarkable.
Claims (1)
1. contact-type honeycomb seal structure body is characterized in that: in the middle of Honeycomb steam seal parent ring (1), be provided with groove (2), spring (3) and interior ring (4) are housed in groove.
