The present embodiments relate to a guiding device for guiding a gas through a gas pressure device.
FIG. : 1 illustrates a schematic representation of a conventional guiding device 100 for guiding a gas through a gas pressure device, and in the embodiment shown in FIG. In the embodiment shown in 1, the # gas pressure device is typically a blower 102. The conventional guiding device 100 includes a conventional thrust ring 130 disposed in the blower 102.
The deflector ring 130 is attached to the inner surface of the housing 105 of the blower 102 using the bracket 110, and the gas flows into the blower 102 through the deflector ring 130. FIG. 2 illustrates a schematic representation of a conventional bracket 110 used to mount the thrust ring 130 on an inner surface 105 of a housing of the blower 102.
In the conventional guiding device 100, the thrust ring 130 is mounted on the inner surface 105 of the housing of the blower 102 using the bracket 110.
The holes 112 on the bracket are configured on the conventional bracket 110. The holes 112 on the bracket are configured to receive fasteners for the connection, and the fasteners are used for a fixed connection between mutual devices.
More specifically, one end of the conventional bracket 110 is connected to the inner surface 105 of the housing of the blower 102, while the other end is connected to the thrust ring 130, so that the thrust ring 130 is attached to the inner surface 105 of the housing of the blower 102. is mounted.
The configuration of the thrust ring 130 is shown in FIG. 3. The thrust washer 130 has holes 135 that mate with one of the holes 112 configured on the conventional bracket 110.
The conventional bracket 110 is then attached in sequence to the deflector ring 130 and the housing of the blower 102 using the fasteners passing through the holes 112 on the bracket and the holes 135 on the deflector ring.
| In practice, the thrust ring 130 must be mounted in several places in the # housing of the blower to direct the gas to the flow. For example, the conventional guiding device 100 can be used at different # locations per stage in the housing of the blower 102, as long as the # 5 thrust ring 130 is connected to the housing of the blower 102.
However, when the conventional guiding device 100 is mounted on the housing of the blower 102, the conventional guiding device 100 takes longer to mount because 130 holes must be drilled on each thrust ring to make connection easier. Gas flow is partially obstructed in the blower 102 by the arrangement of the thrust washer 130, the bracket 110 and the fasteners. The flow restriction of the gas decreases its speed, further affecting the performance of the blower 102 and reducing the efficiency of the blower 102. Furthermore, such a flow restriction can lead to turbulence in the gas flow, which is not desirable. Furthermore, the conventional guiding device 100 has higher manufacturing costs, assembly costs and inventory costs.
The present description discloses a guiding device for guiding a gas through a gas pressure device which eliminates the need for a bracket, fasteners and associated connection holes and does not impede gas flow through the gas pressure device.
FIG. 4 illustrates a cross-section of a guiding device in accordance with one embodiment of the present description. The guiding device 200 is configured for guiding a gas through a gas pressure device. The term "gas" refers to a single gas or gas mixture. In one embodiment, the gas is air. The gas pressure devices are all devices that pressurize the received gas. The gas pressure devices include low pressure devices, such as a blower.
| BE2020 / 5199 # or high pressure devices such as a compressor. For better explanation of the 9 embodiments of the present description, in the present embodiment, the gas pressure device 290 is a blower. The blower has at least one stage. In another embodiment, the blower is a multi-stage blower with multiple stages.

Furthermore, each of the edges of the outer surface 220 has a smooth curvature to allow the gas to flow. . Referring to Fig. 5, since the guide portion 210 is a partial ring structure rather than a closed structure, the guide portion 210 has a pair of opposite ends that are a first end 230 and a second end 235. The configuration of the guide portion 210 is such that a gap 212 is defined between the first end 230 and the second end 235, and the configuration of the gap 212 facilitates mounting of the guide portion 210.
More specifically, the guide portion 210 has a circular or substantially circular configuration. The first end 230 and the second end 235 make an angle (α) ranging from 5 ° to 20 ° with the center of the guide portion 210. In one embodiment, the first end 230 and the second end 235 make an angle (α) in opposite directions. ) ranging from 8 ° to 15 ° with the center of the guide portion 210. In another embodiment, the first end 230 and the second end 235 are opposed to an angle (α) ranging from 10 ° to 12 ° with the center. of the guide part
210.
To facilitate mounting of the guide part 210, the guide part 210 is made elastic. When mounted in the gas pressure device 290, the guide part 210 provides a spring effect comparable to that of a circlip. More specifically, the guide portion 210 is pushed inwardly during mounting in the gas pressure device 290. When the force on the guide part 210 is released, the à / BE2020 / 5199 guide part 210 regains its original shape due to its elastic character, | so that it can be rigidly mounted on the gas pressure device 290. Furthermore, the guide part 210 can be of any material. In one embodiment, the guide portion 210 is made of metallic material. 9 The metallic material can provide strength and stiffness to 9 guide portion 210 necessary for practical operation and use in the 9 gas pressure device 290. As mentioned above, the guide device 200 includes at least one guide portion 210, a lip 225 and at least one groove 250 In concrete terms, this means that the lip 225 in the guide device 200 protrudes radially from an outer edge of the guide portion 210. In one embodiment, during the manufacturing process, the lip 225 and guide portion 210 are integrated into the production. In another embodiment, the lip 225 extends from an edge of the operative exterior 220 of the guide portion 210. In yet another embodiment, the lip 225 is perpendicular to the first end 235 and the second end 230 of the guide portion 210.
Furthermore, as shown in Fig. 7, the guiding device 200 also includes at least one groove 250 configured in the gas pressure device, particularly on a working inner surface 270 of the gas pressure device 290. The groove 250 is configured around the lip 225 in the gas pressure device. guide device 200, thereby securing guide portion 210 in gas pressure device 290 using groove 250. In another embodiment, lip 225 is removably received in groove
250. In one embodiment, because the guide portion 210 is resilient in nature, the guide portion 210 is placed in the groove 250 by the
| move first end 230 and second end 235 towards each other to elastically deform guide portion 210. 9 In one embodiment, as shown in FIG. 8, the groove 250 is configured on fixed vanes of an intermediate portion 300 arranged in the gas pressure device 290. The intermediate part 300 is a circular part that acts as a housing for the gas pressure booster device 290. The gas pressure device 290 includes a plurality of intermediate parts 300 arranged in the gas pressure device 290, and these intermediate parts 300 are configured to define a number of steps in the gas pressure device 290. More specifically, in the gas pressure device 290, impellers are mounted on a rotating shaft 310 of the gas pressure device 290 and each impeller is arranged between two consecutive intermediate parts 300. Fixed vanes are provided on each of the intermediate members 300 to allow the gas to flow. The groove 250 is configured on the edges of the fixed vanes of each intermediate portion 300 to receive the guide portion 210. In one embodiment, it should be noted that the intermediate members 300 and the guide member 210 do not rotate together.
in one embodiment, the intermediate members 300 are made by a molding process and seals are applied between the rotating shaft 310 and the intermediate members 300. During practical assembly, the dimensions of the groove 250 are configured so that the lip 225 on the guide member 210 is secure. can be received in the groove 250. More specifically, the groove 250 and lip 225 of the guide portion 210 are sized such that the guide portion 210, once mounted, does not get out of position.
To mount the guide portion 210 on the intermediate portion 300, the guide portion 210 can be pushed inward so that the first end
| 230 and the second end 235 of the guide portion 210 come closer together or overlap each other. The pressed guide portion 210 is then placed in the housing of the gas pressure device 290, so that the lip 225 is received in the groove 250. Furthermore, once the external force applied to the guide portion 210 will deform the guide portion 210 to expand, thereby properly locating the guide portion 210 in the housing instead of being improperly positioned.
