Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aero-engine design technology, and specifically relates to a simulated hydraulic loading power generation device. Background Technology
[0002] Conventional aero-engine power extraction uses a material pump. However, with the continuous development of new aero-engine models, the power extraction capacity of the material pump is no longer sufficient. Therefore, a simulated hydraulic loading method is used to extract power, which can meet the power extraction requirements of new aero-engine models.
[0003] As the power extracted by simulated hydraulic loading increases, the extracted energy becomes wasteful. Conventionally, the extracted power is cooled by circulating water within the plant, converting the mechanical energy into heat energy for cooling and release.
[0004] The insufficient development capability, low extraction power, high price, and long cycle of aviation material pumps indirectly limit the development of high thrust bypass ratio engines, and are also detrimental to green and environmentally friendly production. Utility Model Content
[0005] Purpose of the utility model: In view of the above background, this invention provides a simulated hydraulic loading power generation device. Mechanical energy is extracted from the power shaft-connected fuselage and converted into kinetic energy, which is then converted into electrical energy by the simulated hydraulic loading power generation device and fed back into the power grid. This further provides the necessary power energy to power-consuming equipment, forming a closed-loop industrial grid. This also solves the problem of power extraction limitations in aero-engine development and meets the requirements of green energy.
[0006] Technical solution
[0007] A simulated hydraulic loading power generation device includes: a hydraulic motor, a connecting shaft, and a generator;
[0008] The hydraulic motor is connected to the output terminal of the simulated power device in the engine flywheel casing;
[0009] The hydraulic motor is connected to the generator via a connecting shaft;
[0010] The electrical energy generated by the generator is fed back into the power grid.
[0011] Furthermore, the device also includes: an adapter;
[0012] One end of the adapter is connected to the hydraulic motor, and the other end is connected to the generator. The adapter is coaxial with the connecting shaft and is used to fix the hydraulic motor and the engine.
[0013] Furthermore, the generator is connected to the test bench distribution cabinet via a cable.
[0014] Furthermore, the generator outputs constant frequency alternating current.
[0015] Furthermore, the generator outputs direct current.
[0016] Furthermore, the generator's power output is positively correlated with the power extracted by the hydraulic motor from the output of the simulated power device in the engine's flywheel casing.
[0017] In summary, the beneficial effects of this utility model are as follows:
[0018] This utility model is easy to maintain and has a simple structure. It features a simpler connection structure than military-grade aviation material pumps, effectively solving the compatibility problem. It can meet the power extraction requirements of new aero-engine models, ensuring effective support during the development of new aero-engines and raising the power capability of these new models to a new level. It effectively overcomes the problems of insufficient development capability, low power extraction, and high cost of military-grade aviation material pumps, thus enhancing the power extraction development capability of aero-engines and further meeting the needs of green energy. The simulated hydraulic loading power generation device has a simpler connection method than conventional power generation devices and can be well used for power extraction from different engine models. The goal is to convert mechanical energy into electrical energy and provide a reliable power supply for the test bench equipment, thus achieving energy reuse and green energy. Currently, the power supply for engine test benches is supplied by the mains to the test bench distribution cabinet, and then distributed to various equipment power points. Each engine test consumes a certain amount of mains power. However, the power extracted from the engine flywheel casing consumes mechanical energy through the factory's circulating cooling water. This long-term, repeated cycle of engine power supply wastes a lot of energy and contradicts the current advocacy of "green energy." A device is needed to recover the energy extracted from the engine and then provide a long-term, stable power supply to the equipment, achieving energy reuse. Attached Figure Description

[0020] 1-Hydraulic motor; 2-Adapter; 3-Connecting shaft; 4-Generator. Detailed Implementation
[0021] A simulated hydraulic loading power generation device includes a hydraulic motor, an adapter, a connecting shaft, and a generator. The adapter has a coaxially arranged connecting shaft, one end of which is connected to the hydraulic motor and the other end to the generator. The adapter is used to fix the hydraulic motor and the generator. The kinetic energy from the outlet of the simulated power device of the engine flyweight casing is transferred to the inlet of the hydraulic loading power generation device, causing the hydraulic motor to rotate at high speed, driving the connecting shaft, and then driving the generator to rotate. One rotation collects electricity and feeds it back into the power grid, providing a stable power supply for the test bench equipment.
[0022] This utility model is easy to maintain and has a simple structure. Compared with conventional power generation devices, it is simpler to connect and can be well used to extract power from different types of engines, converting mechanical energy into electrical energy, and providing power to test bench equipment, achieving green and environmentally friendly energy reuse. The power extracted from the engine flywheel casing consumes mechanical energy through the factory's circulating cooling water. This long-term, repeated engine power supply test wastes a lot of energy, which contradicts the current advocacy of "green energy". There is a need for a device to recover the energy extracted from the engine and then provide a long-term, stable power supply to the equipment, achieving energy reuse.
[0023] Example:
[0024] In a specific embodiment of the present invention, the main technical parameters of the simulated hydraulic loading power generation device are as follows:
[0025] Mode 1: Input maximum speed: 4074 r / min, power extracted from the fly-mounted casing is 52.5 KW, and the power generated by the hydraulic loading generator is 42 KW.
[0026] Mode 2: Maximum input speed: 3780 r / min, power extracted from the flywheel casing: 40.0 KW, power generated by the hydraulic loading generator: 30.0 KW.
[0027] Mode 2: Maximum input speed: 2940 r / min, power extracted from the flywheel casing: 33.0 KW, power generated by the hydraulic loading generator: 24.0 KW.
[0028] Note: The power generation device has certain mechanical efficiency issues and not all of it is used for power generation. The greater the power extracted by the fly-attached casing, the greater the power generation and the higher the mechanical efficiency.
[0029] This utility model discloses a simulated hydraulic loading power generation device. When in use, it extracts the mechanical energy extracted from the engine's flywheel casing and converts it into kinetic energy. Then, the hydraulic loading power generation device converts it into electrical energy, which is fed back to the test bench's power distribution cabinet to provide a stable and long-term power supply to various devices, achieving energy reuse and responding to the "green energy" initiative.
