Description

Technical Field

[0001] The invention relates to the technical field of mechanical engineering, and in particular to a method and an auxiliary device for dynamic balancing and debugging of a rotor. Background Art

[0002] Rotors are widely used in various mechanical equipment. However, due to manufacturing errors, improper installation and other reasons, rotors are often unbalanced. Unbalanced rotors will vibrate when rotating, reducing the operating stability of the equipment and shortening the service life of the equipment. Therefore, dynamic balancing of the rotor is of great practical significance.

[0003] During the dynamic balancing process of the rotor, a removable mass body is often added to the rotor to meet the set requirements for the rotor unbalance. After passing the test, the removable mass body is permanently fixed to the rotor. Plastic deformation of the components will occur during the permanent fixing process, which may cause the rotor unbalance amount to still fail to meet the set requirements after the dynamic balancing is completed. Summary of the invention

[0004] The object of the present invention is to provide a method for dynamic balancing of a rotor to ensure that the unbalance amount of the rotor meets the set requirements after the dynamic balancing is completed.

If the judgment result is no, the dynamic balance is preliminarily qualified and enters S70. If the judgment result is yes, the dynamic balance is determined to be unqualified and returns to S40; S70: permanently fix the detachable mass body on the rotor to obtain the rotor after fixed weight; S80: perform dynamic balance test on the rotor after fixed weight; and S90: determine whether the imbalance of the rotor after fixed weight exceeds the target imbalance limit. If the judgment result is no, the dynamic balance is determined to be qualified and the debugging is completed. If the judgment result is yes, the dynamic balance is determined to be unqualified and returns to S40.

[0007] The method for dynamic balancing and debugging of a rotor can ensure that the unbalance amount of the rotor does not exceed the target unbalance amount limit after the dynamic balancing and debugging is completed, and the unbalance amount of the rotor before the permanent fixed detachable mass body is controlled not to exceed the intermediate unbalance amount limit, which is beneficial to improving the efficiency of dynamic balancing and debugging of the rotor.

[0008] In another exemplary embodiment of the rotor dynamic balancing debugging method, the rotor dynamic balancing debugging method further includes S09 before S10: querying the rotor information database according to the rotor identity information to obtain the target unbalance limit value of the corresponding rotor. The rotor information database contains the corresponding relationship between the rotor identity information and the target unbalance limit value. This helps to improve data accuracy and reliability.

[0009] In another exemplary embodiment of the rotor dynamic balancing method, the rotor is marked with a QR code corresponding to the rotor identity information. The rotor dynamic balancing method further includes S08 before S09: scanning the QR code on the rotor to obtain the rotor identity information. This helps to improve efficiency.

[0010] In another exemplary implementation of the rotor dynamic balancing method, in S10, the intermediate unbalance limit value = the target unbalance limit value × (1-X), where X is the absolute value of the maximum change rate of the rotor unbalance value before the permanent fixing of the detachable mass body relative to the rotor unbalance value after the permanent fixing of the detachable mass body. This helps to further improve the efficiency of the rotor dynamic balancing.

[0011] The present invention also provides an auxiliary device for rotor dynamic balancing debugging, which is used to assist in implementing the above-mentioned rotor dynamic balancing debugging method. The auxiliary device includes a data processing module. The data processing module is configured to implement S30, S60 and S90 of the above-mentioned rotor dynamic balancing debugging method to obtain a determination result of the rotor's dynamic balancing qualified state.

The barcode scanner can obtain the rotor identity information by scanning the QR code on the rotor and send the obtained rotor identity information to the data processing module. This helps to improve efficiency.

[0015] In another schematic embodiment of the auxiliary device for rotor dynamic balancing debugging, the auxiliary device also includes a cylinder state monitoring module, a detection information extraction module and a motor speed extraction module which are signal-connected to the data processing module. The cylinder state monitoring module is used to monitor the telescopic state of the lifting cylinder.

[0035] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0036] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0037] In order to simplify the drawings, each figure only schematically shows the parts related to the present invention, which do not represent the actual structure of the product.

[0038] Figure 1 The following is a flow chart of an exemplary implementation of a method for rotor dynamic balancing. Figure 1 As shown, the method for dynamic balancing of a rotor includes the following steps S10 to S90.

[0039] S10: Generate an intermediate unbalance limit value that is less than the target unbalance limit value according to the target unbalance limit value of the rotor. The target unbalance limit value is the upper limit of the unbalance value of a qualified rotor. In an exemplary embodiment, the intermediate unbalance limit value = target unbalance limit value × (1-X), where X is the absolute value of the maximum rate of change of the rotor unbalance value before the permanent fixing of the detachable mass body relative to the rotor unbalance value after the permanent fixing of the detachable mass body, which reflects the influence of the permanent fixing of the detachable mass body on the rotor unbalance value. For example, if the absolute value of the maximum rate of change of the rotor unbalance value before the permanent fixing of the detachable mass body relative to the rotor unbalance value after the permanent fixing of the detachable mass body is 30%, then the intermediate unbalance limit value is 0.7 times the target unbalance limit value. But it is not limited to this. In other exemplary embodiments, other methods can also be used to determine the intermediate unbalance limit value.

[0040] S20: Perform a dynamic balancing test on the initial rotor using a dynamic balancing machine to obtain a dynamic balancing test result of the initial rotor. The dynamic balancing test result includes an unbalance amount and an unbalance phase angle.

[0041] S30: Determine whether the initial rotor imbalance exceeds the target imbalance limit. If the determination result is no, the dynamic balance is determined to be qualified and the debugging is completed. If the determination result is yes, the dynamic balance is determined to be unqualified and enter S40.

[0042] S40: Add and / or reduce the detachable mass body on the rotor according to the dynamic balancing test result to obtain a weighted rotor. In an exemplary embodiment, the rotor is provided with a balancing nail extending along its axial direction, and the detachable mass body is, for example, a gasket that can be sleeved on the balancing nail. After the gasket is sleeved on the balancing nail, the friction between the gasket and the balancing nail can prevent the gasket from falling off during the dynamic balancing test.

[0043] S50: using a dynamic balancing machine to perform a dynamic balancing test on the weight-adjusted rotor to obtain a dynamic balancing test result of the weight-adjusted rotor.

[0044] S60: Determine whether the unbalance of the rotor after weight adjustment exceeds the intermediate unbalance limit. If the determination result is no, determine that the dynamic balance is preliminarily qualified and enter S70. If the determination result is yes, determine that the dynamic balance is unqualified and return to S40.

[0045] S70: Permanently fix the detachable mass body on the rotor to obtain a weighted rotor. In an exemplary embodiment, the permanent fixation is achieved by riveting, for example, during which the balancing pins are plastically deformed, so that the gasket cannot be removed from the balancing pins. During riveting, the rotor needs to be removed from the dynamic balancing machine to prevent damage to the rollers of the dynamic balancing machine that support the rotor.

[0046] S80: Use a dynamic balancing machine to perform a dynamic balancing test on the weighted rotor to obtain a dynamic balancing test result of the weighted rotor.

[0047] S90: Determine whether the unbalance of the rotor after weight fixation exceeds the target unbalance limit. If the determination result is no, the dynamic balance is determined to be qualified and the debugging is completed. If the determination result is yes, the dynamic balance is determined to be unqualified and the process returns to S40.

[0048] The method for dynamic balancing and debugging of a rotor can ensure that the unbalance amount of the rotor does not exceed the target unbalance amount limit after the dynamic balancing and debugging is completed, and the unbalance amount of the rotor before the permanent fixed detachable mass body is controlled not to exceed the intermediate unbalance amount limit, which is beneficial to improving the efficiency of dynamic balancing and debugging of the rotor.

[0049] like Figure 1As shown, in an exemplary embodiment, the method for rotor dynamic balancing commissioning further includes S09 before S10: querying a rotor information database according to the rotor identity information to obtain a target unbalance limit value of the corresponding rotor. The rotor information database contains a correspondence between the rotor identity information and the target unbalance limit value. The rotor information database is stored in a cloud server, for example. This helps to improve data accuracy and reliability.

[0050] In an exemplary embodiment, the rotor is marked with a QR code corresponding to the rotor identity information. Figure 1 As shown, the rotor dynamic balancing debugging method further includes S08 before S09: scanning the QR code on the rotor to obtain rotor identity information, thereby improving efficiency.

[0051] Figure 2 The structure block diagram of a schematic implementation of an auxiliary device for rotor dynamic balancing and debugging is shown in FIG. The auxiliary device for rotor dynamic balancing and debugging is used to assist in implementing the above-mentioned method for rotor dynamic balancing and debugging. Figure 2 As shown, the auxiliary device 100 includes a data processing module 10. The data processing module 10 is configured to implement S30, S60 and S90 of the above-mentioned rotor dynamic balancing debugging method to obtain the determination result of the dynamic balancing qualified state of the rotor. The determination result of the dynamic balancing qualified state includes dynamic balancing qualified, dynamic balancing unqualified and dynamic balancing preliminarily qualified.

[0052] Using the auxiliary device for rotor dynamic balancing debugging to implement rotor dynamic balancing debugging helps to ensure that the imbalance of the rotor does not exceed the target imbalance limit after the dynamic balancing debugging is completed, and by controlling the imbalance of the rotor in front of the permanently fixed detachable mass body not to exceed the intermediate imbalance limit, it is beneficial to improve the efficiency of rotor dynamic balancing debugging.

[0053] In an illustrative embodiment, the data processing module 10 can query the rotor information database according to the rotor identity information to obtain the target imbalance limit of the corresponding rotor. The rotor information database contains the correspondence between the rotor identity information and the target imbalance limit. The rotor information database is stored in the cloud server 300, for example. This helps to improve data accuracy and reliability. The data processing module 10 is configured to implement S10 of the above-mentioned rotor dynamic balancing debugging method, that is, it can generate an intermediate imbalance limit value less than the target imbalance limit value according to the target imbalance limit value of the rotor. The specific algorithm for generating the intermediate imbalance limit value according to the target imbalance limit value has been described above and will not be repeated here. But it is not limited to this. In other illustrative embodiments, other methods can also be used to determine the intermediate imbalance limit value.

[0054] In an exemplary embodiment, the rotor is marked with a QR code corresponding to the rotor identity information. Figure 2As shown, the auxiliary device 100 further includes a barcode scanner 20. The barcode scanner 20 is connected to the data processing module 10. The barcode scanner 20 can obtain rotor identity information by scanning the QR code on the rotor and send the obtained rotor identity information to the data processing module 10. This helps to improve efficiency.

[0055] like Figure 2 As shown, in the exemplary embodiment, the auxiliary device 100 further includes a cylinder state monitoring module 30 , a detection information extraction module 40 and a motor speed extraction module 50 which are signal-connected to the data processing module 10 .

[0056] The cylinder state monitoring module 30 is used to monitor the telescopic state of the lifting cylinder. The lifting cylinder is used to lift the rotor loaded on the dynamic balancing machine when the detachable mass body is permanently fixed, and reload the rotor to the dynamic balancing machine after the implementation is completed. The cylinder state monitoring module 30 is, for example, a photoelectric sensor.

[0057] The detection information extraction module 40 is connected to the dynamic balancing machine 200 to obtain the dynamic balancing detection result. The dynamic balancing machine, for example, includes a display unit (for example, but not limited to a digital tube display) for displaying the dynamic balancing detection result. The detection information extraction module 40 is connected to the display unit to obtain the dynamic balancing detection result, for example, but not limited to this.

[0058] The dynamic balancing machine 200 includes a rotor drive motor for driving the rotor to rotate. The motor speed extraction module 50 is connected to the rotor drive motor of the dynamic balancing machine 200 to obtain the speed information of the rotor drive motor.

[0059] The data processing module 10 can determine whether there is a behavior of permanently fixing the detachable mass body according to the output signal of the cylinder state monitoring module 30. For example, if it is determined according to the output signal of the cylinder state monitoring module 30 that the lifting cylinder is extended and retracted once, it is determined as a behavior of permanently fixing the detachable mass body.

[0060] The data processing module 10 can also determine whether the rotor drive motor has stopped according to the output signal of the motor speed extraction module 50, and when it is determined that the rotor drive motor has stopped, extract the current dynamic balancing test result from the detection information extraction module 40, and determine whether the current dynamic balancing test result belongs to the initial rotor, the rotor after weight adjustment, and the rotor after weight fixation according to whether the dynamic balancing test result is extracted for the first time and whether there is a behavior of a permanently fixed and detachable mass body after the last dynamic balancing test result is extracted. The "first time" and "last time" are both for the same rotor being debugged.

[0061] Specifically, for example, if the dynamic balancing test result is extracted for the first time, the dynamic balancing test result is marked as the dynamic balancing test result of the initial rotor. If the dynamic balancing test result is not extracted for the first time, and there is no behavior of permanently fixing a detachable mass body after the last dynamic balancing test result is extracted, the dynamic balancing test result is marked as the dynamic balancing test result of the rotor after weight adjustment. If the dynamic balancing test result is not extracted for the first time, and there is an behavior of permanently fixing a detachable mass body after the last dynamic balancing test result is extracted, the dynamic balancing test result is marked as the dynamic balancing test result of the rotor after weight adjustment.

[0062] like Figure 2 As shown, in the exemplary embodiment, the auxiliary device 100 further includes a loading state monitoring module 60 connected to the data processing module 10 by signal. The loading state monitoring module 60 is used to monitor whether the rotor is loaded on the dynamic balancing machine. The loading state monitoring module 60 is, for example, a photoelectric sensor. The data processing module 10 can determine whether there is a rotor loading behavior based on the output signal of the loading state monitoring module 60. This is conducive to automatically monitoring the rotor loading behavior.

[0063] In an illustrative embodiment, the data processing module 10 is also capable of: generating a prompt message to prompt the user to scan the QR code on the rotor when it is determined that there is rotor loading behavior; generating a prompt message to prompt the user to perform a dynamic balancing test on the rotor when the target unbalance limit and the intermediate unbalance limit of the rotor are obtained; generating a prompt message to prompt the user to add and / or reduce removable masses on the rotor and then perform a dynamic balancing test on the rotor when the result of the dynamic balancing qualified state is that the dynamic balancing is unqualified; generating a prompt message to prompt the user to permanently fix the removable masses on the rotor and then perform a dynamic balancing test on the rotor when the result of the dynamic balancing qualified state is that the dynamic balancing is preliminarily qualified; and / or generating a prompt message to prompt the user to complete the debugging when the result of the dynamic balancing qualified state is that the dynamic balancing is qualified. Figure 2 As shown, the auxiliary device 100 also includes a prompt module 70. The prompt module 70 is connected to the data processing module 10 and can generate a sound signal or a light signal according to the prompt information to prompt the user. The prompt module 70 is, for example, a display or a speaker. This can guide the user, which is conducive to improving ease of operation and reducing the error rate of operation.

[0064] In an exemplary embodiment, the data processing module 10 can also generate a result signal according to the dynamic balance test result and output it to the prompt module 70. The prompt module 70 can generate a sound signal or a light signal according to the result signal to inform the user of the dynamic balance test result.

[0065] like Figure 2As shown, in the exemplary embodiment, the auxiliary device 100 further includes a storage module 80 and a transmission module 90. The storage module 80 can store the data received and processed by the data processing module 10. The transmission module 90 is connected to the storage module 80 by signal and can send the data stored in the storage module 80 to the cloud server 300 by wire or wireless means. This can facilitate the storage and management of information related to the dynamic balancing commissioning of the rotor.
