Abstract
The utility model relates to an air cooler core sealing device of a centrifugal air compressing machine. The device comprises a rubber sealing strip, a cooler core sealing surface and a fixed bolt, wherein a stainless steel pipe is arranged under the cooler core sealing surface; and the stainless steel pipe, the rubber sealing strip and the cooler core sealing surface form a labyrinth sealing structure. In the utility model, as the stainless steel pipe is arranged, the rubber sealing strip, the stainless steel pipe and the cooler core sealing surface form the labyrinth seal, thereby enhancing the gas tightness of the cooler, reducing the energy consumption of the centrifugal air compressing machine and prolonging the service life of the centrifugal air compressing machine.
Description
Technical field
The utility model relates to a kind of seal arrangement, is specifically related to the seal arrangement of centrifugal air compressor gas cooler.
Technical background
Before the utility model proposes, the seal form of centrifugal air compressor gas cooler is the obstruction seal form that rubber plate and cooler core sealing surface form, as shown in Figure 1.Rubber plate at high temperature uses for a long time, easily aging fracture, and the part high-temperature gas does not enter cooler core and cools off and directly enter next stage and compress.Gas at high temperature compresses, and the centrifugal air compressor energy consumption will increase on the one hand; On the other hand, can't condensation efflux and directly enter the next stage impeller, will produce corrosion, reduced the working life of centrifugal air compressor the next stage impeller without the moisture in the high-temperature gas of cooling.
Summary of the invention
The purpose of this utility model is to provide a kind of seal arrangement of centrifugal air compressor gas cooler, and to solve sealing instability in the prior art, rubber weather strip is aging easily, influences bubble-tight technical problem.
For reaching above purpose, the technological scheme that the utility model adopted is: it comprises rubber weather strip, cooler core sealing surface, fixing bolt, be provided with Stainless Steel Tube below described cooler core sealing surface, Stainless Steel Tube and rubber weather strip and cooler core sealing surface form labyrinth seal structure.
Described Stainless Steel Tube is two, is symmetrically arranged in the rubber weather strip both sides.
Described Stainless Steel Tube is welded on the cooler core sealing surface.
The beneficial effects of the utility model are: by Stainless Steel Tube is set, make and form labyrinth seal between rubber weather strip, Stainless Steel Tube and the sealing surface, strengthen the tightness of cooler, reduced the energy consumption of centrifugal air compressor, prolonged the working life of centrifugal air compressor.
Description of drawings
Fig. 1 is existing centrifugal air compressor gas cooler core schematic diagram of sealing device.
Fig. 2 is the utility model centrifugal air compressor gas cooler core schematic diagram of sealing device.
Wherein, 1-rubber weather strip, 2-cooler core sealing surface, 3-Stainless Steel Tube, 4-fixing bolt.
Embodiment
Be described further below in conjunction with the enforcement of accompanying drawing: on the sealing surface 2 of centrifugal air compressor cooler core, weld two Stainless Steel Tubes 3 as shown in Figure 1 the utility model centrifugal air compressor gas cooler core seal arrangement, two stainless steel pipes rubber weather strip 1 both sides that are placed in, form labyrinth seal between rubber weather strip, Stainless Steel Tube and the sealing surface like this, produce throttle effect during gap that sealed air forms and reach the purpose that stops air leakage between by rubber weather strip and Stainless Steel Tube.Through after transforming, gas drops to 35 ℃ through supercooler is laggard before going into turbine temperature by original 55 ℃, has satisfied the intake temperature stipulated in the technology operation rules less than 45 ℃ requirement.
In order to make the utility model centrifugal air compressor gas cooler core seal arrangement reach best airtight effect, be the centrifugal air compressor of H700-6.8/097-1 for model, its Stainless Steel Tube diameter is 18mm, length is 3200mm.Such design can reach the effect of best labyrinth seal.
Claims (3)
