Abstract
The utility model provides an inclined honeycomb type sealing structure of ferrite, which comprises a brush gland casing and is characterized in that an inclined honeycomb belt is arranged at the bottom of the brush gland casing, and the honeycomb belt and the brush gland casing are made of the ferrite. The ferrite is hard in quality, thereby being capable of further narrowing a radial gap between a gland and a rotor. Simultaneously, the inclined honeycomb belt can improve turbulent flow effects of a honeycomb chamber.
Description
Technical field
The utility model relates to the ferrite inclination honeycomb sealing configuration that is used for vapour (gas) sealing in a kind of turbomachinery.
Background technique
Turbomachinery is the driving type fluid machinery with blade.The common feature of turbomachinery is that bladed rotor is made high speed rotary motion, when fluid (gas or liquid) is flowed through between the blade passage, produces the interaction of power between blade and the fluid, so as to realizing Conversion of energy.In turbomachinery, because mostly the Honeycomb steam seal material in existing vapour (gas) sealing configuration is Alloy Constructional Steel 15CrMoA, its quality is softer relatively, and therefore, the radial clearance between packing and the rotor is bigger.
Summary of the invention
The purpose of the utility model provides a kind of sealing configuration that reduces the radial clearance between packing and the rotor.
In order to achieve the above object; The technological scheme of the utility model has provided a kind of ferrite inclination honeycomb sealing configuration; Comprise the brush steam seal body, it is characterized in that: be provided with the cellular band of inclination in the bottom of brush steam seal body, cellular band and brush steam seal body adopt ferrite to make.
Its quality of ferrite in the utility model is harder, therefore, can further reduce the radial clearance between packing and the rotor, and simultaneously, the cellular band of inclination can strengthen the flow-disturbing effect of honeycomb chamber.
Description of drawings
The structural representation of a kind of ferrite inclination honeycomb sealing configuration that Fig. 1 provides for the utility model.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
A kind of ferrite inclination honeycomb sealing configuration as shown in Figure 1, that the utility model provides comprises brush steam seal body 1, is provided with the cellular band 2 of inclination in the bottom of brush steam seal body 1, and cellular band 2 and brush steam seal body 1 adopt ferrite to make.
Alloy Constructional Steel 15CrMoA is relative, and ferrite is softer, so ferrite brush seal structure can further be dwindled the radial clearance between packing and the rotor, and has improved the vacuum tightness of unit.And there is several angle in meeting between vapour side and the rotor of the cellular band of labyrinth ring, so more strengthened the flow-disturbing effect of honeycomb chamber.
Claims (1)
1. a ferrite inclination honeycomb sealing configuration comprises brush steam seal body (1), it is characterized in that: be provided with the cellular band (2) of inclination in the bottom of brush steam seal body (1), cellular band (2) and brush steam seal body (1) adopt ferrite to make.
