Description

Technical Field

[0001] This invention relates to the field of aero-engine technology, and in particular to a device and method for optimizing the performance of a blower used for sand removal in a particle separator. Background Technology

[0002] A particle separator is an engine intake protection device. Its function is to separate various foreign objects, mainly sand and dust, carried in the intake air from the engine, preventing them from entering the engine. This reduces engine wear and damage, thereby improving engine reliability and service life. In other words, it provides intake protection for the engine. Figure 1 .

[0003] The blower is the suction device in the particle separator's clearing flow system. Its function is to extract the clearing flow containing sand, gravel, and other foreign matter and discharge it outside the machine. The blower impeller is driven by an accessory drive belt, and the design speed of the blower used for sand discharge is generally greater than 10,000 r / min.

[0004] The sand removal blower is a key component in the particle separator's cleaning flow system for extracting sand-laden exhaust gas, driven by mechanical power extracted from engine accessory drives. With the increasing demands on engine performance, higher requirements are placed on the power extraction and operational reliability of engine accessories. For the sand removal blower, high efficiency under single-phase aerodynamic flow is required to reduce power extraction from the engine, while also considering factors such as size, weight, and abrasion. To meet the analytical needs of optimizing the aerodynamic characteristic parameters of the sand removal blower, performance tests of the blower (mixed-flow blower) are necessary to assess and verify its performance indicators, allowing for continuous improvement and iteration until the required performance and speed are achieved. However, currently, no publicly available technical methods for optimizing the performance of blowers in aero-engine particle separator sand removal devices have been found.

[0005] In view of this, it is imperative to design a blower performance test to optimize the aerodynamic characteristics of the sand-discharging blower, so that it can have the highest possible sand and dust suction efficiency while extracting as little engine power as possible, in order to meet the ever-increasing engine performance requirements.

[0078] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0079] This invention addresses the lack of effective testing devices and methods for optimizing the performance parameters of sand-discharging blowers in existing technologies. It innovatively designs a performance optimization device for sand-discharging blowers used in particle separators. Please refer to [link to relevant documentation]. Figure 2 As shown, the main components of the device include: a high-speed electric spindle 1, a transmission box 2, an air inlet pipe 3, a blower 4, a surge relief solenoid valve 5, an outlet regulating valve 6, a monitoring system, a determination system, and a display system. The high-speed electric spindle 1 and the transmission box 2 together serve as the power supply mechanism for driving the impeller of the blower 4 to rotate at different real-time speeds. By adjusting the outlet regulating valve 6 located at the exhaust end of the blower 4, the flow rate within the blower 4 can be arbitrarily adjusted. During this process, to prevent the flow rate within the blower 4 from falling below a safe value and causing surge, this application also includes a surge relief solenoid valve 5 on the blower 4 body. This valve is used to monitor the opening of the outlet regulating valve 6 in real time, changing the air inlet flow rate and pressure ratio within the blower 4 to ensure it remains in a stable working state for an extended period. Based on this, the monitoring system acquires the real-time speed of blower 4, the real-time vibration values ​​of the drive mechanism and blower 4, the total inlet pressure, total inlet temperature, and static pressure of the inlet wall at the inlet measuring section of the blower 4's air inlet flow pipe 3; and the total outlet pressure and total outlet temperature at the outlet measuring section of blower 4. Then, the determining system, based on the acquired total inlet pressure, total inlet temperature, static pressure of the inlet wall, total outlet pressure, and total outlet temperature, can realize the real-time acquisition of blower performance parameters such as pressure ratio, efficiency, equivalent flow rate, and power consumption of blower 4. Finally, the display system displays the real-time speed of blower 4, the pressure ratio, efficiency, and equivalent flow rate of blower 4 at different real-time speeds in the form of equivalent flow rate-pressure ratio characteristic curves and equivalent flow rate-efficiency characteristic curves. At the same time, the power consumption of blower 4 at different real-time speeds and the real-time vibration monitoring values ​​of high-speed electric spindle 1 and blower 4 are also displayed in real time. Ultimately, by reading the data displayed on the screen, the optimal settings for performance parameters such as the speed and flow rate of the blower can be achieved under the premise that the device is operating stably.

[0080] Specifically, the high-speed electric spindle 1 can be connected to the spindle of the transmission box 2 via a bellows coupling. The other end of the spindle of the transmission box 2 can be connected to the shaft of the blower 4 via internal and external splines. During the test, the control speed of the high-speed electric spindle 1 is adjusted. When the speed reaches the specified state, the airflow in the blower 4 is changed by adjusting the opening of the outlet valve 6. After the state stabilizes, various aerodynamic parameters (including total temperature, total pressure, and static pressure) at the inlet and outlet measurement sections of the blower 4 can be recorded. Then, the pressure ratio, efficiency, equivalent flow rate, and power consumption can be calculated using the following formulas.

[0081] ①Pressure ratio, calculated using the following formula:

[0082] ;

[0083] In the formula: P t1 —Total inlet pressure, taken as atmospheric pressure (unit: Pa);

[0084] P t2 —The total pressure at the outlet is the arithmetic mean of the total pressure measured by at least three 4-point comb-shaped total pressure test tubes at section II-II (the outlet measurement section) (unit: Pa).

[0085] ② Efficiency, calculated using the following formula:

[0086] ;

[0087] In the formula: the variable specific heat coefficient k = 1.4;

[0088] T t0 The total inlet temperature (unit: K) is the total temperature measured by at least one single-point total temperature probe at section I-I (the inlet measurement section);

[0089] T t2 The total outlet temperature is the arithmetic mean (unit: K) of the total temperatures measured by at least two total temperature tubes at section II-II (the outlet measurement section).

[0090] ③Flow rate: Flow rate calculation formula:

[0091] ;

[0092] In the formula: ;in,

[0093] ;in,

[0094] P S The arithmetic mean (unit: Pa) of the static pressure measured at least 4 points on the inlet flow measuring tube 3.

[0095] ④ Converted flow rate: The calculated flow rate is converted into the flow rate under standard temperature and pressure conditions for comparative analysis. The specific calculation formula is as follows:

[0096] = ;

[0097] In the formula: Represents equivalent flow rate, unit: kg / s.

[0098] ⑤ Power consumption, power consumption calculation formula:

[0099] ;

[0100] Power unit: kW.

[0101] Furthermore, the selection of measurement sections and arrangement of measurement points during the testing of parameters such as total temperature, total pressure, and static pressure at the inlet and outlet measurement sections can be found in Table 1 below:

[0102] Table 1. Layout of measuring points at each measurement section

[0103]

[0104] (1) Inlet measurement section II:

[0105] Inlet measuring section II is set on inlet flow tube 3. Please refer to [link / reference]. Figure 2 As shown, the probes are specifically positioned at a straight-line distance of 3 to 5 times the diameter of the measuring section II from the inlet section of the blower 4. At least four wall static pressure test probes are arranged on the inlet measuring section, with the distribution being similar to... Figure 3 The section shown is II-II, and at least one single-point total temperature measurement probe is used to obtain the inlet total temperature value at that point, and atmospheric pressure is used as the inlet total pressure value of the inlet flow tube 3.

[0106] (2) Exit measurement section II-II:

[0107] Section II-II is positioned at a straight-line distance from the outlet section of blower 4, which is 3 to 5 times the diameter of the outlet measuring section. A schematic diagram of the specific measuring point arrangement on section II-II can be found in [reference needed]. Figure 3 As shown.

[0108] (a) Figure 3 The four static pressure points on the wall are respectively located at (circumferentially at 67.5°, 157.5°, 247.5°, and 337.5°, and axially aligned with the comb-shaped total pressure probe tip, for monitoring the airtightness of the device throughout the process and preventing air leakage).

[0109] (b) Three comb-shaped total pressure measurement probes at four points (circumferentially located at 0°, 90°, and 180°);

[0110] (c) Two single-point total temperature measurement probes (circumferentially located at 135° and 315°).

[0111] When performing total pressure measurement, the total pressure sensing head must be directly facing the airflow direction. The static pressure measurement orifice should be perpendicular to the airflow direction. Furthermore, it is worth noting that those skilled in the art will readily conceive of how to adjust the positions of the total temperature, total pressure, and static pressure test probes at the inlet and outlet measurement sections. Therefore, any adjustments to the probe positions made without departing from the technical objective of obtaining the total temperature, total pressure, and static pressure test values ​​at the inlet and outlet measurement sections should be within the scope of protection of this invention.

[0112] Furthermore, the following test piece debugging requirements must be met during the testing process:

[0113] The principle for adjusting the speed of blowers at different real-time speeds is to adjust from low speed to high speed, and to do so in stages within the test range.

[0114] Throughout the testing process, the maximum speed should be strictly controlled, and the vibration of the high-speed electric spindle 1 and blower 4 should be closely monitored; and the vibration limits should be noted as follows:

[0115] Vibration limit values: The vibration values ​​and transient vibration values ​​of the blower body shaft bearing support casing and the high-speed electric spindle 1 bearing support casing should be less than the specified values.

[0116] Speed ​​limits: Ensure the test is conducted within the maximum speed limit whenever possible. Speeds exceeding 400-600 rpm are permissible.

[0117] Rotation direction: As per design requirements.

[0118] Furthermore, the following can be monitored and displayed during the test:

[0119] (1) Parameter display

[0120] It includes real-time monitoring parameters at various measuring points such as temperature and pressure, including the average values ​​of total inlet and outlet temperature and total pressure; as well as performance parameters such as speed, flow rate, pressure ratio, efficiency, and power consumption.

[0121] (2) Display curve

[0122] 1) Blower reduced flow rate-efficiency, reduced flow rate-pressure ratio characteristic curves;

[0123] 2) Real-time vibration monitoring values ​​and change curves;

[0124] A single point can be selected vertically from the blower, and two points, one vertically and one horizontally from the high-speed electric spindle body, to display the vibration values ​​on the screen in real time. (The preferred measuring points are on the casing near the blower bearing and the motor spindle bearing.)

[0125] (3) Real-time speed display;

[0126] A speed sensor can be integrated into the high-speed electric spindle, allowing the detection signal to be displayed in real time via a speed display and a data acquisition screen.

[0127] Furthermore, the specific experimental steps are as follows:

[0128] 1) Turn on the high-speed electric spindle 1 and gradually increase the speed from low to high, thus increasing the relative reduced speed coefficient. Controlled =0.5, 0.6, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1.0 ( (e.g., n0 = 26000 r / min) Run each speed for 2-3 minutes and record the corresponding flow parameters at the bottleneck and surge points at each real-time speed.

[0129] Relative reduced speed coefficient The calculation formula is as follows:

[0130] ;

[0131] In the formula, n is the real-time rotational speed of the blower under different conditions; n0 is the design rotational speed of the blower of the sand removal device, which is usually greater than 10000 r / min. Unit: revolutions per minute.

[0132] In actual calculations, the real-time speed of the blower can be approximated as n= n0; and from At least 8 coefficient values ​​are selected sequentially from 0.4 to 1.0, and the calculated real-time rotational speed n is used as the test conditions for different real-time rotational speeds of the present invention.

[0133] 2) Next, restart the high-speed electric spindle, gradually increasing the speed. Once the selected speeds have stabilized, adjust the opening of the outlet regulating valve 6 to change the pressure ratio and adjust the flow rate from the blockage point to the surge point.

[0134] During this period, admission Under several measurement conditions with different speed coefficients (0.5, 0.6, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1.0), the main aerodynamic parameters (total temperature, total pressure, static pressure) at the inlet and outlet measurement sections of the blower are recorded as the flow rate decreases from high to low.

[0135] It should be ensured that the flow control in the blower has at least 7 flow status points, including blockage point and surge point, under test conditions of different real-time speeds.

[0136] Next, the blower test piece was selected. The general characteristic curves (reduced flow rate-pressure ratio characteristic curve and reduced flow rate-efficiency characteristic curve) for different speed coefficients (0.5, 0.6, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1.0) are shown in the following figure. Figure 4 , Figure 5 As shown.

[0137] 3) The above test content can be added to or adjusted according to the actual situation. For example, the highest efficiency point and the highest pressure ratio point can be determined based on the determined reduced flow rate-pressure ratio characteristic curve and reduced flow rate-efficiency characteristic curve; and the selection of flow rate test state points near the highest efficiency point and the highest pressure ratio point can be increased, and the optimized reduced flow rate-pressure ratio characteristic curve and reduced flow rate-efficiency characteristic curve can be re-determined until the optimal blower control speed, flow rate, etc. that simultaneously achieve the highest suction efficiency and the lowest power consumption can be determined as the performance parameter settings of the particle separator blower, thereby optimizing the performance of the blower.

[0138] The experiment is now complete. Power is cut off, and the optimization experiment is finished.

[0139] This test method has been used in the performance test of the blower of the sand discharge system of the relevant aviation particle separator. It can effectively carry out performance comparison and analysis. After the test, the blower completed various verification tests with the engine and worked well.

[0140] In summary, the particle separator sand removal blower performance optimization device of the present invention, by setting up components such as a drive mechanism, an outlet regulating valve, a surge relief solenoid valve, a monitoring system, a determination system, and a display system, innovatively provides an experimental method for effectively comparing and analyzing the performance parameters of sand removal blowers. This fills the gap in the existing technology where effective selection of performance parameters for blowers configured on the sand removal devices of aero-engine particle separators is not possible. This design device and testing method can effectively guide the optimization design of the aerodynamic characteristic parameters of the sand removal blower, enabling the blower to have high sand and dust suction efficiency while extracting as little engine power as possible, thereby helping to meet the ever-increasing performance and reliability requirements of aero-engines.

[0141] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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.
