Description

Technical Field

[0001] This invention belongs to the field of injector technology, and specifically relates to a control method for an adjustable injector. Background Technology

[0002] An ejector is a vacuum-generating device that uses fluid to transfer energy and mass. It employs pressurized water flow, which is ejected through symmetrically distributed nozzles at a certain angle and converges at a single focal point. Atomizing nozzles, as devices that atomize liquid and uniformly suspend it in the air, are widely used in various industrial fields. They work by forcing liquid into the nozzle under internal pressure, and by placing an iron plate inside the nozzle, the high-speed liquid impacts and bounces, forming atomized particles that are then ejected through the nozzle outlet.

[0003] However, the spray cone angle of existing injectors is determined by their own structure, and the angle cannot be changed according to actual needs. Furthermore, it is impossible to perceive the sprayed medium, the atomization effect of the medium, and the actual effective space of the atomized medium, which reduces the effectiveness of the injector. At the same time, the atomized cooling medium sprayed by the injector cannot be accurately applied to high-temperature areas, which reduces the cooling performance of the sprayed medium. Summary of the Invention

[0004] This invention provides a control method for an adjustable injector. By inputting the high-temperature limit of the object being tested into the control unit, and detecting the boundary of the high-temperature region using a temperature detection device, the method sequentially determines whether the position and angle of the spray cone angle of the injector body and the output structure are reasonable. Closed-loop control is then performed using the control unit to ensure that the control structure reaches the appropriate position, thereby automatically adjusting the injector's position and direction. Simultaneously, the output structure sprays an appropriate amount of cooling medium onto the surface of the object being tested, improving cooling efficiency and performance.

[0005] A control method for an adjustable injector, acting on the adjustable injector, which includes an injector body, an output structure, and a control structure. The output structure is disposed on the injector body and is used to spray atomized cooling medium. The control structure is used to control the movement of the injector body and adjust the position and angle of the output structure. The method includes the following steps:

[0006] S1: Input the high temperature limit of the object being measured into the control unit;

[0007] S2: Use a temperature detection device to detect and determine whether there are points on the surface of the object being tested whose temperature exceeds the set high temperature limit, and connect all the points that exceed the high temperature limit to form the boundary of the high temperature area;

[0008] S3: Detect and determine whether the position and angle of the spray cone angle of the current injector body and the current output structure are reasonable, and control the control structure to adjust to a reasonable position and angle through the control unit;

[0009] S4: The output structure sprays atomized cooling medium onto the surface of the object being tested until there are no points on the surface of the object exceeding the high temperature limit.

[0010] By inputting the high temperature limit of the object under test into the control unit, and detecting the boundary of the high temperature area through the temperature detection device, the system sequentially determines whether the position and angle of the spray cone of the injector body and the output structure are reasonable. The control unit performs closed-loop control, and the control structure is controlled to reach the reasonable position, thereby achieving the purpose of automatically adjusting the position and direction of the injector. At the same time, the output structure can spray an appropriate amount of cooling medium onto the surface of the object under test, improving cooling efficiency and cooling performance.

[0011] Furthermore, in step S2, if there are no points on the surface of the object being tested where the temperature exceeds the set high temperature limit, the testing continues until the cooling process ends.

[0012] Furthermore, the temperature detection device employs an infrared thermal sensor; the infrared thermal sensor is mounted on the injector body.

[0013] Furthermore, step S3 includes the following steps:

[0014] S31: The distance between the injector body and the boundary of the high-temperature area is measured by a position detection device. The control unit receives the feedback signal from the position detection device, performs atomization calculation to determine whether the position is reasonable, and controls the control structure to adjust it to a reasonable position.

[0015] S32: The control unit analyzes and determines whether the spray area of ​​the spray cone angle of the current output structure can completely cover the boundary of the high-temperature area, and uses the control unit to control the control structure to adjust the spray cone angle until the control unit determines that it can completely cover the boundary of the high-temperature area.

[0016] Furthermore, in S31, the position detection device is a laser locator; the laser locator is mounted on the injector body.

[0017] Furthermore, in S32, when the spray area of ​​the spray cone angle of the current output structure can completely cover the boundary of the high-temperature area, no adjustment is made until the cooling ends.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention adjusts the position and angle of the injector body to a suitable spray cone angle by controlling the structure, which facilitates precise cooling of the object being tested.

[0020] 2. This invention inputs the high temperature limit of the object under test into the control unit, detects the boundary of the high temperature area through a temperature detection device, and sequentially determines whether the position and angle of the spray cone angle of the injector body and the output structure are reasonable. The control unit performs closed-loop control, and the control structure is controlled to reach the reasonable position, thereby achieving the purpose of automatically adjusting the position and direction of the injector. At the same time, it enables the output structure to spray an appropriate amount of cooling medium onto the surface of the object under test, thereby improving the cooling efficiency and cooling performance.

[0034] A control method for an adjustable injector, which acts on the adjustable injector. For example... Figure 1 As shown, the adjustable injector includes:

[0035] Injector body 11;

[0036] The output structure 12 is disposed on the injector body 11 and is used to spray atomized cooling medium.

[0037] The control structure 13 is used to control the movement of the injector body 11 and adjust the position and angle of the output structure 12.

[0038] The position of output 11 is adjusted by controlling structure 13, and the angle of output structure 12 is adjusted to a suitable spray cone angle, so as to facilitate precise cooling of the object under test.

[0039] In this embodiment, as Figures 2-4 The figures shown are schematic diagrams of the external and internal structures of the adjustable injector.

[0040] The output structure 12 consists of a cone-shaped rocker arm 121 and a spray ball head 122. The two cone-shaped rocker arms 121 are respectively connected to the injector body 11, and the spray ball head 122 is placed on the cone-shaped rocker arm 121. The spray ball head 122 is provided with a spray hole 124 for spraying cooling medium.

[0041] The control structure 13 includes a solenoid valve 131 and a drive motor 132. The solenoid valve 131 is located at the midpoint of the top of the injector body 11 and is flush with the front edge of the injector body 11. The solenoid valve 131 is connected to the injection ball head 122 and controls the injection ball head 122 to spray. The drive motor 132 is connected to the cone-shaped rocker arm 121 through the connecting push rod 123 and is used to drive the connecting push rod 123 to move up and down, thereby driving the cone-shaped rocker arm 121 to move, and then driving the injection ball head 122 to rotate.

[0042] The position of the adjustable injector and the angle of the injection ball head 122 are adjusted by controlling the cone-angle rocker arm 121 through the drive motor 132; the opening and closing of the injection ball head 133 is controlled by the opening and closing of the solenoid valve 131, thereby spraying the atomized cooling medium to the high-temperature area to be cooled, thus achieving precise spraying.

By inputting the high-temperature limit of the object being tested into the control unit, and detecting the boundary of the high-temperature zone using a temperature detection device, the method sequentially determines whether the position and angle of the spray cone angle of the injector body 11 and the output structure 12 are reasonable. Closed-loop control is then implemented using the control unit, and the control structure 13 is controlled to reach the appropriate positions, thereby achieving automatic adjustment of the injector's position and direction.
