Description

Technical Field

[0001] This utility model relates to the field of dynamic balancing technology for TPS turbine power simulators, specifically an online dynamic balancing device for TPS turbine power simulators. Background Technology

[0002] Turbine power simulators utilize fluid impact to drive a rotating impeller, generating power for the engine. They are widely used in the aerodynamic testing phase of aero-engine prototype development. However, errors in component design, manufacturing, and assembly can lead to imbalances in the rotor system of turbine power simulators, affecting test speeds and other performance parameters.

[0003] Traditional methods involve disassembling the rotor and replacing the impeller, but due to the original imbalance, vibration may still exceed limits after reinstallation, and it is difficult to accurately reflect the actual imbalance state of the rotor during operation. Online dynamic balancing technology is based on rotor dynamics theory. It determines the magnitude and azimuth of the unbalanced mass by analyzing the relationship between centrifugal force and vibration phase, and then achieves balance by adding or removing weight. Utility Model Content

[0004] The purpose of this invention is to provide an online dynamic balancing device for a TPS turbine power simulator to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online dynamic balancing device for a TPS turbine power simulator, comprising a frame, a vibration sensor, and a speed sensor. A floating clamping assembly and a displacement nozzle assembly are installed on the top of the frame, an air supply pump is installed at the bottom of the frame, and an electrical control module is installed at the rear of the frame. The air supply pump and the electrical control module are connected through an air supply pipe, and the electrical control module and the displacement nozzle assembly are connected through an exhaust pipe.

[0006] Preferably, the speed sensor is a multi-joint magnetic speed sensor.

[0007] Preferably, the floating clamping assembly consists of a housing clamping seat and a plurality of flexible support plates, on which vibration sensors are adsorbed.

[0008] Preferably, the displacement nozzle assembly includes a nozzle ring, a nozzle ring mounting base, and a manual digital display slide. The manual digital display slide drives the nozzle ring mounting base to reciprocate. The nozzle ring mounting base is fitted with a nozzle ring. The nozzle ring is fitted with a plurality of ball-head nozzles at equal intervals. The nozzle ring is also fitted with a nozzle ring connector.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. Multiple flexible support plates on the floating clamping assembly can amplify the vibration of the TPS turbine power simulator, and the vibration sensor adsorbed on the flexible support plate facilitates the acquisition of vibration signals.

[0012] 3. The electrical control module can regulate the air supply flow and pressure. At the same time, the acquired speed sensor signal can assist in controlling the speed of the TPS turbine power simulator. Combined with the vibration signal, the magnitude and direction of the unbalanced mass in the current state can be calculated. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0023] like Figure 6-7 The TPS turbine power simulator 100 consists of a central shaft 101, an intake cone 102, a fan impeller 103, a turbine impeller 104, a fan casing 105, and an intermediate casing 106.

[0024] Please see Figure 1-5 In this embodiment of the present invention, an online dynamic balancing device for a TPS turbine power simulator includes a frame 600, a vibration sensor 401, and a speed sensor 402. The speed sensor 402 is a multi-joint magnetic speed sensor. A floating clamping assembly 200 and a displacement nozzle assembly 300 are installed on the top of the frame 600. An air supply pump 500 is installed at the bottom of the frame 600, and an electrical control module 400 is installed at the rear of the frame 600. The air supply pump 500 and the electrical control module 400 are connected through an air supply pipe 700, and the electrical control module 400 and the displacement nozzle assembly 300 are connected through an exhaust pipe 800. The air control module can adjust the air supply flow rate and pressure. At the same time, the collected speed sensor signal can assist in controlling the speed of the TPS turbine power simulator. Combined with the vibration signal, the magnitude and direction of the current unbalanced mass can be calculated.

[0025] The floating clamping assembly 200 consists of a casing clamping base 201 and multiple flexible support plates 202. Vibration sensors 401 are adsorbed on the flexible support plates 202. The multiple flexible support plates on the floating clamping assembly can amplify the vibration of the TPS turbine power simulator, and the vibration sensors adsorbed on the flexible support plates facilitate the acquisition of vibration signals.

[0026] The displacement nozzle assembly 300 includes a nozzle ring 301, a nozzle ring mounting base 304, and a manual digital display slide 305. The manual digital display slide 305 drives the nozzle ring mounting base 304 to reciprocate. The nozzle ring mounting base 304 is equipped with the nozzle ring 301. The nozzle ring 301 is equipped with multiple ball-head nozzles 302 at equal intervals. The nozzle ring 301 is also equipped with a nozzle ring connector 303. The nozzle ring mounting base and the manual digital display slide, with multiple ball-head nozzles on the nozzle ring, can be adapted to multiple angles to make the airflow direction adjustable. The manual digital display slide can move the nozzle ring axially, which facilitates the online de-duplication processing of the TPS turbine power simulator.

[0027] The working principle of this utility model is as follows: A TPS turbine power simulator 100 is mounted on a casing clamping base 201. A vibration sensor 401 is adsorbed onto a flexible support plate 202. A speed sensor 402 is mounted on the rear side of the TPS turbine power simulator in the machining 600 and adjusted to collect the turbine blade speed. An exhaust pipe 800 is connected to a nozzle ring connector 303 on a nozzle ring 301. The relative position of the nozzle ring 301 and the TPS turbine power simulator 100 is adjusted and locked using a manual digital display slide 305, adapting to the posture of the nozzle 302 so that the exhaust gas from the nozzle 302 can drive the fan impeller to rotate. The exhaust pressure and flow rate are adjusted by the electrical control module 400, and combined with the collected turbine speed signal, real-time control of the TPS turbine power simulator speed is achieved. The vibration signal collected by the vibration sensor 401 can be used to solve for the magnitude and direction of the current unbalanced mass. During the unbalanced weight removal operation, the impeller discs of both the fan impeller and the turbine impeller are selected. When removing weight from the fan impeller, the nozzle ring needs to be moved out by operating the manual digital display slide to leave enough space for the weight removal operation.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
