Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings.
In one aspect, embodiments of the present invention provide a turbocharger driving apparatus for driving a turbocharger to operate by a generated airflow. The turbocharger driving device comprises an air inlet pipeline, an exhaust pipeline and a plurality of combustion chambers which are arranged in parallel; the air inlet pipeline is used for providing air required by combustion for the combustion chamber, and the air outlet pipeline is used for leading airflow generated in the combustion chamber to the turbocharger so as to drive the turbocharger to operate.
As shown in fig. 1 and 2, the combustion chamber 10 includes: a combustion chamber housing 101, a flame tube 102 mounted in the combustion chamber housing 101, an ignition device 103, a fuel nozzle 104, and a swirler 105; the combustion chamber case 101 is configured as a through cylindrical structure, with an intake port of the combustion chamber 10 located at one end (upper end in the drawing) of the combustion chamber case 101, and an exhaust port of the combustion chamber 10 located at the other end (lower end in the drawing) of the combustion chamber case 101. The fuel may be natural gas, gasoline, etc.
Air enters the combustion chamber shell 101 from the air inlet, fuel sprayed from the nozzle passes through the swirler and is combusted with the entering air in the flame tube 102 of the combustion chamber 10 to generate high-temperature and high-pressure air flow, and the air flow is sprayed from the air outlet.
With combined reference to fig. 1 and 2, in the embodiment provided by the present invention, the intake circuit comprises a primary intake circuit 11 and a secondary intake circuit 12, and the exhaust circuit comprises a primary exhaust circuit 13 and a secondary exhaust circuit 14; the number of the combustion chambers 10, the number of the branch intake pipelines 12 and the number of the branch exhaust pipelines 14 are the same, the intake ports of each combustion chamber 10 are respectively in one-to-one butt joint with the branch intake pipelines 12, and the exhaust ports of each combustion chamber 10 are respectively in one-to-one butt joint with the branch exhaust pipelines 14.
After entering the primary intake pipe 11, the air flows to each branch intake pipe 12 to supply air to each combustion chamber 10, and the air is mixed with fuel entering the combustion chamber 10 and ignited to generate high-speed airflow to drive the turbocharger to operate.
If the intake air amount of one combustion chamber 10 is changed independently, the flow rate of the high-speed airflow generated by the combustion chamber 10 is changed correspondingly, but in order to ensure the working stability of the combustion chamber 10, the adjustment range of the intake air amount of the single combustion chamber 10 is limited to a certain extent. The turbocharger driving apparatus of the embodiment of the present invention, having a plurality of combustion chambers 10 arranged in parallel, can adjust the amount of high-speed airflow generated by the apparatus by adjusting the number of combustion chambers 10 involved in operation and the intake air amount of the intake pipe, and thus can achieve the purpose of wide-range adjustment.
Specifically, as shown in fig. 1, in order to achieve more accurate adjustment, in the first embodiment of the present invention, the turbocharger drive apparatus includes a plurality of valve bodies 15, and a valve body 15 is provided between each of the combustion chambers 10 and the branch intake pipe 12 that are butted against each other.
That is, each combustion chamber 10 is provided with a valve body 15 for adjusting the amount of intake air thereof.
Wherein the valve body 15 may be mounted between the branch intake conduit 12 and the combustion chamber 10, or alternatively, the valve body 15 is mounted in the branch intake conduit 12.
In the embodiment provided by the present invention, the valve body 15 is installed between the branch intake pipe 12 and the combustion chamber 10. The branch intake pipe 12, the valve body 15, and the combustion chamber 10 are connected to each other by flanges (not shown), and the branch exhaust pipe 14, the valve body 15, and the combustion chamber 10 are connected to each other by flanges. This kind of connected mode not only can reduce the complex degree during the assembly, can also effectively promote the stability of connecting.
Specifically, as shown in fig. 1, in the embodiment provided by the present invention, the intake pipe has three branch intake pipes 12; the primary inlet line 11 is interfaced with three branch inlet lines 12 by a four-way junction 16. Correspondingly, three combustion chambers 10 and three branch exhaust pipelines 14 are respectively arranged; the primary exhaust line 13 is interfaced with three secondary exhaust lines 14 via a four-way junction 16. Of course, in order to reduce the use costs of the constituent components and improve the assembly efficiency, the four-way 16 connecting the primary intake pipe 11 and the secondary intake pipe 12 is identical to the four-way 16 connecting the primary exhaust pipe 13 and the secondary exhaust pipe 14 in the embodiment provided by the present invention; i.e. the two cross-ways 16 can be replaced by each other.
In the embodiment provided by the present invention, as shown in FIG. 1, the cross 16 is configured in a cross-shape. Of course, in other embodiments, the shape configuration of the cross 16 is not limited to being a cross. In addition, when the number of the branch intake pipes 12 (the combustion chambers 10 and the branch exhaust pipes 14) is two, four, or more, other shape-configured connecting members may be used. For example, when the number of the branch intake pipes 12 (the combustion chambers 10 and the branch exhaust pipes 14) is two, a three-way valve may be employed.
The valve body 15 may be an electromagnetic valve or a valve body 15 that is opened and closed manually, which is not limited in this embodiment of the present invention.
As shown in fig. 1, the following manner can be referred to when adjusting the exhaust gas amount of the turbocharger drive apparatus provided in the present embodiment.
When the required amount of exhaust gas is small, only one valve body 15 may be opened to allow one combustion chamber 10 to participate in the operation.
For example, only the left, right, or middle valve body 15 may be opened.
When the required amount of exhaust gas is large, the two valve bodies 15 can be opened to allow the two combustion chambers 10 to participate in the operation.
For example, the left and right valve bodies 15, or the left and middle valve bodies 15 may be opened.
When the required amount of exhaust gas is larger, all of the three valve bodies 15 can be opened to allow the three combustion chambers 10 to participate in the operation.
Further, the amount of exhaust gas from the combustion chamber 10 can be adjusted by controlling the opening/closing size of one of the valve elements 15 and the size of fuel supply in the combustion chamber 10.
In a specific application, a person skilled in the art may perform adaptive adjustment according to actual requirements, and details are not described in this embodiment.
In addition, as shown in fig. 2, in the second embodiment provided by the present invention, the turbocharger drive apparatus further includes an orifice plate 17; an orifice plate 17 is mounted in the branch inlet conduit 12 opposite the primary inlet conduit 11. As shown in fig. 3, the orifice plate 17 has an orifice hole 171 and a connection hole 172; the orifice 171 is used to produce a throttling effect on the gas flow passing therethrough; the connection hole 172 is adapted to be installed in the intake pipe by means of a connection member (e.g., a bolt, a pin, etc.).
In particular, the intake circuit has three branch intake circuits 12; the primary inlet line 11 is interfaced with three branch inlet lines 12 by a four-way junction 16. Correspondingly, three combustion chambers 10 and three branch exhaust pipelines 14 are respectively arranged; the primary exhaust line 13 is interfaced with three secondary exhaust lines 14 via a four-way junction 16. Of course, in order to reduce the use costs of the constituent components and improve the assembly efficiency, the four-way 16 connecting the primary intake pipe 11 and the secondary intake pipe 12 is identical to the four-way 16 connecting the primary exhaust pipe 13 and the secondary exhaust pipe 14 in the embodiment provided by the present invention; i.e. the two cross-ways 16 can be replaced by each other.
In the present embodiment, an orifice plate 17 is installed in the branch intake pipe 12 opposite to the primary intake pipe 11 to generate a throttling effect, so that the airflow of the primary intake pipe 11 can be effectively dispersed into the three branch intake pipes 12; meanwhile, the purpose of dispersing the air into the three branch air inlet pipelines 12 with the same air quantity can be achieved by adjusting the aperture size in the aperture plate 17.
In addition, in order to adjust the exhaust gas amount of the entire turbocharger drive apparatus, in the present embodiment, a regulator valve 18 is further provided.
A regulator valve 18 is mounted to the primary air intake pipe 11 for regulating the intake air flow rate of the primary air intake pipe 11.
The amount of air entering each combustion chamber 10 can be controlled by adjusting the amount of air entering the primary air intake conduit 11 by means of the regulating valve 18; meanwhile, in order to ensure the normal operation of the combustion chamber 10, the fuel supply amount may be adjusted in combination.
In addition, in order to realize finer adjustment, the intake pipe of the present embodiment may be further provided with the valve body 15 in the first embodiment described above.
Of course, in other embodiments, the number of secondary intake conduits 12 (combustion chambers 10 and secondary exhaust conduits 14) is not limited to three, and thus is not limited to the use of the four-way junction 16.
For example, when the number of the branch intake pipes 12 (the combustion chambers 10 and the branch exhaust pipes 14) is two, a three-way valve may be used, and in this case, it is considered that the orifice plate 17 is not provided.
For example, when the number of the branch intake pipes 12 (the combustion chambers 10 and the branch exhaust pipes 14) is four, an orifice plate 17 may be provided in at least one of the branch intake pipes 12. Of course, those skilled in the art can adjust the number of the orifice plates 17 and the specific arrangement in which branch intake pipe 12 according to actual requirements, which will not be described in detail in this embodiment.
In a second aspect, embodiments of the present invention further provide a test bench, configured to test performance of a turbocharger; which includes the turbocharger drive apparatus in any of the embodiments described above.
The test bed can be used for testing the rotating speed, the service life and the like of the turbocharger under different air inflow (exhaust amount of the turbocharger driving device) working conditions.
Those skilled in the art can adjust the test bed according to different test requirements.
For example, the test stand may include a temperature sensor or the like when it is desired to test the temperature change of the turbocharger.
