Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of engines, and in particular to an oil supply component and a gas turbine engine having the same. Background Art
[0002] A gas turbine engine is a device that converts the chemical energy of fuel into mechanical work. The fuel is supplied to the fuel atomizer through the fuel supply component, and the fuel atomizer atomizes the fuel and supplies the oil mist to the combustion chamber for combustion, generating high-temperature combustion gas to drive the turbine to output mechanical work.
[0003] The fuel atomization component of the existing combustion chamber is an oil-slinging plate connected to the main shaft of the engine, and the oil supply component that supplies oil to the oil-slinging plate is generally fixedly installed on the back of the diffuser. In this case, the oil supply component is the stator component, and the oil-slinging plate is the rotor component. There will be a sealing gap between the two after installation, and the gap needs to be sealed to avoid oil and gas crossflow. Since the grate seal can be applied to high-speed rotating equipment, the grate seal is widely used in gas turbine engines. That is, during implementation, the gas turbine engine uses a grate seal structure to seal the gap between the rotor and the stator. At this time, the grate seal structure gap between the rotor and the stator is about (0.3-0.8) mm.
[0004] However, during the engine starting phase, due to the low speed of the oil slinger, the fuel atomization effect is not ideal, and there is a part of un-atomized liquid fuel. This part of the fuel will flow into the grate seal structure between the oil slinger and the oil supply part as it rotates, and even further overflow. The main manifestation is that some fuel accumulates between the grate teeth on the stator and around the grate teeth. If this part of the fuel is not removed in time, when the ambient temperature reaches a certain value, this part of the fuel will have the risk of coking. Coking will cause the grate seal gap to be blocked by coking materials, which will greatly increase the rotation resistance. In severe cases, it will cause the rotor to stagnate, and then the engine cannot be started, resulting in insufficient practicality of the oil supply part. Summary of the invention
[0005] Therefore, the technical problem to be solved by the present invention is that in the prior art, during the engine startup phase, unatomized fuel will enter the spaces between the grate teeth on the stator and be accumulated around the grate teeth.

[0068] It can be explained that, in the oil supply member provided in this embodiment, the medium entering from the cleaning medium inlet 131 can be gas such as high-pressure air, or can be liquid such as cleaning agent.
[0069] like Figures 1 to 9 As shown, the oil supply part provided in this embodiment, the first connecting channel 133 includes a first connecting section 1331 and a second connecting section 1332, the first connecting section 1331 extends along the circumference of the annular wall 111, and the second connecting section 1332 extends along the axial direction of the annular wall 111, the cleaning medium inlet 131 is connected to the first connecting section 1331, and the two ends of the second connecting section 1332 are respectively connected to the first connecting section 1331 and the cleaning medium outlet 132.

[0071] The oil supply part provided in this embodiment does not limit the number of cleaning medium outlets 132, and can be in the form of one group of multiple, or in the form of multiple groups of multiple. It is only necessary to provide multiple cleaning medium outlets 132, and the multiple cleaning medium outlets 132 are arranged at axial intervals along the annular wall 111, and the multiple cleaning medium outlets 132 are all connected to the second connecting section 1332.
[0072] As one of the embodiments, the cleaning medium outlet 132 is in the form of multiple groups. Figures 1 to 9 As shown, the oil supply part provided in this embodiment is provided with a plurality of second connecting sections 1332, and the plurality of second connecting sections 1332 are arranged at circumferential intervals along the annular wall 111; a plurality of cleaning medium outlets 132 are provided, and the plurality of groups of cleaning medium outlets 132 are arranged at circumferential intervals along the annular wall 111, and any group is provided with a plurality of cleaning medium outlets 132 corresponding to and connected with any second connecting section 1332.
[0073] like Figures 1 to 9 As shown, the oil supply member provided in this embodiment has a first connecting section 1331 that penetrates the end of the annular wall 111 and forms a first opening 1334 ; the oil supply member also includes a first cover body 14 , which is covered on the end of the annular wall 111 to close the first opening 1334 .
[0074] like Figures 1 to 9 As shown, in the oil supply part provided in this embodiment, an air injection protrusion 134 is provided on the outer wall of the annular wall 111; a cleaning medium inlet 131 is formed on the air injection protrusion 134; the first connecting channel 133 also includes a third connecting section 1333, the third connecting section 1333 is arranged inside the air injection protrusion 134, and the two ends of the third connecting section 1333 are respectively connected to the cleaning medium inlet 131 and the first connecting section 1331.
[0075] like Figures 1 to 9 As shown, the oil supply member provided in this embodiment further includes a liquid transmission structure 15. At this time, the liquid transmission structure 15 includes a fuel inlet 151, a second communication channel 152 and a fuel outlet 153. The fuel inlet 151 and the cleaning medium inlet 131 are arranged at intervals along the radial direction of the annular wall 111, and the fuel inlet 151 and the comb tooth structure 12 are arranged at intervals along the axial direction of the annular wall 111.

[0077] It can be explained that, in the oil supply component provided in this embodiment, the fuel outlet 153 is opened in the fourth connecting section 1521 .
[0078] Furthermore, the fuel supply member provided in this embodiment does not limit the number of the fuel outlets 153 , which may be two or more. In this case, the fuel outlets 153 are evenly distributed in the fourth connecting section 1521 along the circumferential direction of the annular wall 111 .
[0079] The fuel supply member provided in this embodiment does not limit the structure of the fourth connecting section 1521. It can be a non-connected U-shaped or a connected O-shaped. When it is a U-shaped, the uniformity of the fuel sprayed from each fuel outlet 153 can be better, and when it is an O-shaped, the processing cost of the fourth connecting section 1521 can be reduced.
[0080] like Figures 1 to 9 As shown, in the oil supply part provided in this embodiment, a liquid injection protrusion 154 is provided on the outer wall of the annular wall 111 , and the liquid injection protrusion 154 and the gas injection protrusion 134 are arranged at intervals along the radial direction of the annular wall 111 ; the fuel inlet 151 is formed in the liquid injection protrusion 154 .

[0082] It can be explained that the oil supply member provided in this embodiment does not limit the structure of the cleaning medium outlet 132. In order to increase the range of high-pressure air or cleaning agent flushing the fuel accumulated between the grate teeth 121 and near the grate teeth 121, the structure of the cleaning medium outlet 132 can be set to a tapered hole, so that the high-pressure air or cleaning agent can be dispersed after flowing out of the cleaning medium outlet 132. In addition, in order to increase the force of high-pressure air or cleaning agent to disperse the fuel accumulated between the grate teeth 121 and near the grate teeth 121, the structure of the cleaning medium outlet 132 can be set to a cylindrical hole.
[0083] It can be explained that, in the fuel supply member provided in this embodiment, the axial direction of the fuel outlet 153 is arranged crosswise or parallel to the axial direction of the cleaning medium outlet 132. As one embodiment, the axial direction of the fuel outlet 153 is arranged parallel to the axial direction of the cleaning medium outlet 132.
[0084] Example 2
[0085] This embodiment provides a gas turbine engine, and the oil supply part provided in the above embodiment. Figures 1 to 9 As shown, the gas turbine engine provided in this embodiment further includes an oil slinger 2, an air intake pipe 3, an oil intake pipe 4 and a flame tube 5. The oil slinger 2 includes a second body 21 and an annular groove 211 provided on the second body 21, and the annular groove 211 is used to accommodate the annular wall 111; one end of the air intake pipe 3 is connected to the discharge port of the first storage member storing the cleaning medium, and the other end of the air intake pipe 3 is connected to the cleaning medium inlet 131; one end of the oil intake pipe 4 is connected to the discharge port of the second storage member storing the fuel, and the other end of the oil intake pipe 4 is connected to the fuel inlet 151; the flame tube 5 is movably sleeved on the outer wall of the annular groove 211.
[0086] It can be explained that, in the gas turbine engine provided in this embodiment, the annular wall 111 and the annular groove 211 are arranged coaxially with the engine rotor.
[0087] It can be explained that, in the gas turbine engine provided in this embodiment, the flame tube 5 is located in the combustion chamber of the gas turbine engine.
[0088] It can be explained that if Figure 1As shown, a certain gap is formed between the comb tooth structure 12 and the annular groove 211, and a third connecting channel for fuel oil to flow is formed at the sleeve joint of the flame tube 5 and the annular groove 211. At this time, the third connecting channel is connected to the inner cavity of the flame tube 5, so that the fuel oil dispersed from the cleaning medium outlet 132 can flow from the gap here to the third connecting channel and flow to the inner cavity of the flame tube 5. That is, the gas turbine engine provided in this embodiment, by accommodating the annular wall 111 in the annular groove 211 of the oil-slinging plate 2, and movably sleeved the flame tube 5 on the outer wall of the annular groove 211, so that the fuel oil flows out of the annular wall 111 and enters the oil-slinging plate 2, and the fuel oil can be thrown into the combustion chamber where the flame tube 5 is located with the rotation of the oil-slinging plate 2, so that the fuel oil collides with the air in the flame tube 5, and then the fuel oil is broken into oil mist, and then burned and released heat in the flame tube 5, so that the fuel oil burns more fully.
[0089] It should be noted that, since there is a certain gap between the grate structure 12 and the annular groove 211, if the fuel oil adheres to this gap, coking will occur, which is intuitively manifested as the gap being blocked. Through the setting of the cleaning medium outlet 132, high-pressure air will be sprayed to this gap, and then the fuel oil in the gap will be flushed, thereby achieving the purpose of cleaning the fuel oil and reducing the risk of coking and stagnation. At the same time, if the medium entering from the cleaning medium inlet 131 is a cleaning agent, after the cleaning agent disperses the fuel oil accumulated between the grate teeth 121 and near the grate teeth 121, this part of the cleaning agent will be like the fuel oil. With the action of its own gravity and the action of the thrust generated by the adjacent cleaning agent, it is intuitively manifested that the cleaning agent will be displaced along the radial and axial directions of the annular wall 111, enter the combustion chamber where the flame tube 5 is located through the third connecting channel, and finally be discharged to the outside of the gas turbine engine through the oil leakage valve set on the casing of the combustion chamber. At the same time, if there is still a small amount of cleaning agent in the gas turbine engine after cleaning, high-pressure air is blown into the cleaning medium inlet 131 for air washing.
[0090] Furthermore, if the gas turbine engine is in working condition, the oil inlet pipe 4 supplies fuel to the fuel inlet 151, the fuel will enter the oil throwing plate 2 through the fuel outlet 153, and enter the inner cavity of the flame tube 5 through the third connecting channel for combustion. During this process, the air intake pipe 3 stops supplying cleaning agent or high-pressure air to the cleaning medium inlet 131; if the gas turbine engine is in a shutdown state, the oil inlet pipe 4 stops supplying fuel to the fuel inlet 151, the air intake pipe 3 is opened, and high-pressure air or cleaning agent is supplied to the cleaning medium inlet 131. After the cleaning is completed, the air intake pipe 3 stops supplying cleaning agent or high-pressure air to the cleaning medium inlet 131.
[0091] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
