Description

Technical Field

[0001] This application relates to the field of water pump resonance treatment technology, and in particular to a vibration reduction method and device for a vertical condensate pump. Background Technology

[0002] As one of the three major water pumps in thermal power units, the variable frequency condensate pump plays a crucial role in extracting condensate from the condenser hot well and transporting it to the deaerator. The vertical condensate pump consists of a vertical drive motor, motor support bolts, an upper support cylinder with an outlet, a lower support cylinder with an inlet, and a coupling connecting the upper and lower support cylinders. During the variable frequency operation of the vertical condensate pump, the inherent frequency differences of its internal components and the asymmetrical structural design can cause multiple resonance points at the same rotational speed, leading to accelerated wear of internal components, pipe rupture, and even system shutdown and other safety accidents.

[0003] To address the aforementioned resonance problem, existing technologies generally employ a fine dynamic balancing method. This method primarily optimizes the mass balance of rotating components in a vertical condensate pump to reduce unbalanced excitation forces. However, due to the mechanical structure and multi-component coupling characteristics of vertical condensate pumps, this mass balancing optimization often leads to changes in the system's vibration modes. This causes components that were originally in a non-resonant state to develop new resonance points due to altered vibration characteristics resulting from dynamic balancing adjustments, thus failing to resolve the resonance problem of the vertical condensate pump.

[0004] Therefore, a new method is urgently needed to solve the resonance problem of vertical condensate pumps. Summary of the Invention

[0009] Based on the matching of the real-time rotation speed with the target rotation speed in the preset information database, the preset information database stores the vibration reduction adjustment scheme of the vertical condensate pump at the target rotation speed. The vibration reduction scheme is used to control the vibration reduction device to adjust the support force of the screw supporting the vertical condensate pump at the target rotation speed, so as to adjust the amplitude data corresponding to the resonance point of the vertical condensate pump to the corresponding standard amplitude data range.

[0010] If a match is found, the motor control command is determined based on the corresponding vibration reduction adjustment scheme, and the motor control command is sent to the controller.

[0011] Secondly, this application provides a vibration damping device for a vertical condensate pump.

The fixed bracket is installed outside the vertical drive motor of the vertical condensate pump and is used to fix one end of the motor and the lead screw. The lead screw is arranged opposite to each other along the top of the vertical condensate pump, and the other end of the lead screw abuts against the outer wall of the vertical condensate pump. The device includes:

[0016] Fourthly, this application provides a readable storage medium for storing a computer program, wherein the computer program, when running, controls the device containing the storage medium to perform the vibration reduction method for the vertical condensate pump described above.

[0017] Compared to existing technologies, this application provides a vibration reduction method and apparatus for a vertical condensate pump. This method avoids the problem of new resonance points arising from traditional fine dynamic balancing adjustments by acquiring the real-time rotational speed of the vertical condensate pump and matching it with a preset information database. Specifically, this scheme utilizes vibration reduction schemes stored in the preset information database for each target rotational speed, enabling precise adjustment of the resonance point. These vibration reduction schemes are verified methods that adjust the amplitude corresponding to the resonance point to a standard range, effectively avoiding vibration mode disturbances caused by mechanical structure and multi-component coupling characteristics. Furthermore, the mechanism of real-time matching of rotational speed and vibration reduction schemes allows vibration reduction adjustment to adapt to different operating conditions, suppressing resonance phenomena at their source rather than merely superficially optimizing unbalanced excitation forces. This significantly improves the stability and reliability of the vertical condensate pump operation, reduces the risk of system downtime, and ensures the continuity and safety of condensate delivery from the condenser hot well of thermal power units.

[0025] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0027] As one of the three major water pumps in thermal power units, the variable frequency condensate pump plays a crucial role in extracting condensate from the condenser hot well and transporting it to the deaerator. The vertical condensate pump consists of a vertical drive motor, motor support bolts, an upper support cylinder with an outlet, a lower support cylinder with an inlet, and a coupling connecting the upper and lower support cylinders. During the variable frequency operation of the vertical condensate pump, the differences in the inherent frequencies of its internal components and the asymmetrical structural design can cause multiple resonance points at the same rotational speed, leading to accelerated wear of internal components, pipe rupture, and even system shutdown. To address this resonance problem, existing technologies generally employ a fine dynamic balancing method. This method primarily optimizes the mass balance of rotating components in the vertical condensate pump, thereby reducing the unbalanced excitation force. However, due to the mechanical structure and multi-component coupling characteristics of vertical condensate pumps, this mass balancing optimization operation often leads to changes in the vibration modes of the system. As a result, components that were originally in a non-resonance state will generate new resonance points due to changes in vibration characteristics caused by dynamic balance adjustments, which cannot solve the resonance problem of vertical condensate pumps.

[0028] To address this issue, the inventors of this application propose a vibration reduction method for a vertical condensate pump. This method obtains the real-time rotational speed of the vertical condensate pump. Based on the matching of the real-time rotational speed with a target rotational speed stored in a preset information database, the database contains vibration reduction adjustment schemes for the vertical condensate pump at the target rotational speed. These vibration reduction schemes control the vibration reduction device to adjust the support force of the screw supporting the vertical condensate pump at the target rotational speed, thereby adjusting the amplitude data corresponding to the resonance point of the vertical condensate pump to the corresponding standard amplitude data range. If a match is found, a motor control command is determined based on the corresponding vibration reduction adjustment scheme, and the motor control command is sent to the controller to reduce the amplitude of the resonance point of the vertical condensate pump at different rotational speeds. The specific steps of a vibration reduction method for a vertical condensate pump according to an embodiment of this application are as follows: Figure 1 As shown, it includes:

[0029] Step 101: Obtain the real-time speed of the vertical condensate pump.

[0030] Before formally introducing this embodiment, this embodiment also introduces a vibration damping device, such as... Figure 2a and Figure 2b As shown, the vibration damping device includes a motor, controller, fixed bracket, and lead screw. The fixed bracket is installed outside the vertical drive motor and is used to fix the motor and one end of the lead screw. The lead screw is arranged opposite each other along the top of the pump body, and the other end abuts against the outer wall of the pump body. This arrangement allows the supporting force to be applied along the axial direction of the pump body, effectively counteracting lateral vibration. Real-time speed can be obtained through a speed sensor, such as a magnetoelectric or photoelectric sensor. The adjustment of the lead screw support force is achieved by driving the lead screw to extend or retract via a motor, for example, by using a servo motor to control the lead screw displacement.

[0031] The mounting bracket in the vibration damping device can be rectangular, cubic, cylindrical, prismatic, or other geometric shapes. The specific shape selection needs to comprehensively consider the external dimensions of the vertical condensate pump, installation space limitations, and mechanical performance requirements, and is not limited here. The mounting bracket is typically made of high-strength alloy steel. High-strength alloy steel possesses excellent rigidity and fatigue resistance, making it suitable for long-term stable operation under high load and high vibration environments. Furthermore, to further improve the vibration damping performance of the mounting bracket, rubber vibration isolation pads or spring dampers can be added at the connection points with the vertical drive motor and lead screw. Through the buffering effect of the elastic elements, the vibration transmission path is effectively blocked. The bottom end of the mounting bracket is fixed to the ground.

[0032] As the core control unit of the vibration damping device, the controller typically employs an industrial-grade PLC (Programmable Logic Controller) or a high-performance embedded microcontroller. PLCs possess mature and stable industrial control performance, support multiple communication protocols, and can easily interact with host computers, sensors, and actuators. Embedded microcontrollers offer higher computational efficiency and flexibility, allowing for optimized design for specific vibration damping algorithms, achieving fast and precise control. Furthermore, the controller is equipped with abundant input / output interfaces, such as analog input interfaces for receiving signals from speed and pressure sensors, and digital output interfaces for controlling actuators such as motor drivers and alarm devices, ensuring the stable and efficient operation of the entire vibration damping system. Motor selection is equally crucial. Besides servo motors, stepper motors can also be considered as an alternative for driving the lead screw. Stepper motors offer advantages such as high control precision, fast response speed, and relatively low cost. Through microstepping technology, they can achieve precise control of the lead screw displacement. Servo motors, on the other hand, have advantages in dynamic performance, torque output capability, and closed-loop control precision, making them suitable for applications requiring extremely high vibration damping response speed and control precision. It is worth noting that... Figure 2a and Figure 2b The controller is not shown because its location is not fixed; it only needs to be able to control the motor.

[0033] In this embodiment, the vibration damping device has at least two lead screws. The opposing arrangement refers to the lead screws being symmetrically distributed along the top of the vertical condensate pump with their axes opposite each other; that is, evenly distributed along the circumference with the pump body's central axis as the reference. The number of lead screws is even, specifically four or six, and is not limited here. As a key component for transmitting support force, the lead screw is often a ball screw or a trapezoidal lead screw. Ball screws use rolling friction instead of sliding friction, offering high transmission efficiency, smooth movement, and high positioning accuracy; trapezoidal lead screws have advantages such as simple structure, large load capacity, and good self-locking performance, and can be rationally selected according to actual load requirements and cost budget. Each lead screw has a corresponding motor. The contact side between the lead screw and the pump body can be concave, with the concavity matching the pump body's convexity.

[0034] It's worth noting that the vibration damping device works as follows: Assuming the vertical condensate pump operates at 18 Hz, resonance occurs in the north-south direction (natural frequency 18 Hz). Adjusting the support force of the two electric lead screws in the north-south direction changes the structural stiffness in that direction, thus altering the natural frequency away from 18 Hz. This prevents north-south resonance and reduces amplitude. When the condensate pump continues to operate at 19 Hz, resonance occurs in the east-west direction. At this point, the north-south lead screws stop working, while the east-west lead screws start working, altering the east-west natural frequency away from 19 Hz. This also prevents east-west resonance. If the condensate pump continues to operate at 20 Hz, the amplitude at the resonance point is within the corresponding standard amplitude range, and the lead screws in all directions stop working, allowing the condensate pump to operate normally.

[0035] In this step, during the operation of the vertical condensate pump, the real-time rotational speed of the pump is continuously collected by a speed sensor. This real-time speed can be achieved by installing a Hall effect sensor or a photoelectric encoder on the pump shaft or the motor shaft of the vertical condensate pump. The Hall effect sensor utilizes the principle of electromagnetic induction; when a magnetic element on the pump shaft passes by, a pulse signal is generated, and the rotational speed (RPM) can be converted by calculating the number of pulses per unit time. The photoelectric encoder generates pulses by detecting the light transmission and blocking state of a rotating code disk, offering higher accuracy. To improve reliability, a redundant configuration can be used, installing two independent sensors for cross-validation.

[0036] Step 102: Match the real-time rotation speed with the target rotation speed in the preset information database.

[0037] In this step, the preset information database stores vibration reduction adjustment schemes for the vertical condensate pump at the target speed. These schemes control the vibration reduction device to adjust the support force of the screw supporting the vertical condensate pump at the target speed, thereby adjusting the amplitude data corresponding to the resonance point of the vertical condensate pump to the corresponding standard amplitude data range. The preset information database is constructed through a stepped frequency sweep test, storing the optimal support force parameters at different speeds. The target speed refers to the speed at which the amplitude data of the resonance point generated during the variable frequency operation of the vertical condensate pump does not meet the corresponding standard amplitude data. The preset information database uses a key-value pair structure for storage, where the key is the target speed value and the value is the corresponding vibration reduction adjustment scheme. The standard amplitude data range refers to the resonance that does not affect the normal operation of the vertical condensate pump during operation; that is, the amplitude data within the standard amplitude data range is acceptable.

[0038] The vibration reduction adjustment scheme in the preset information database for this step is a scheme to reduce the amplitude data of the resonance point by using a vibration reduction device at the operating frequency of the vertical condensate pump. This vibration reduction scheme was obtained through training using a vibration reduction device.

[0039] In this step, when matching the real-time rotational speed and the target rotational speed, a match is determined when the real-time speed and the target rotational speed are identical. A tolerance comparison algorithm can be used to determine if there is a preset precision difference between the real-time speed and the target rotational speed. For example, a preset precision difference (an allowable speed deviation range) (e.g., ±5 RPM) can be set. When the real-time speed falls within the tolerance range of a certain target rotational speed, the match is considered successful. For example, if the real-time speed is 1498 RPM, and a target rotational speed of 1500 RPM exists in the preset library, then the vibration reduction scheme corresponding to that target rotational speed is triggered.

[0040] Step 103: If the match is consistent, determine the motor control command based on the corresponding vibration reduction adjustment scheme, and send the motor control command to the controller.

[0041] When the real-time rotational speed matches the target rotational speed in step 102, a motor control command is determined based on the corresponding vibration reduction adjustment scheme, and the motor control command is sent to the controller so that the amplitude data of the resonance point of the vertical condensate pump at the target rotational speed is within the corresponding standard amplitude data range. If they do not match, it means that the amplitude data of the resonance point of the vertical condensate pump at the real-time rotational speed meets the corresponding standard amplitude data range.

[0042] This application provides a vibration reduction method and apparatus for a vertical condensate pump. This method avoids the problem of new resonance points caused by traditional fine dynamic balancing adjustments by acquiring the real-time rotational speed of the vertical condensate pump and matching it with a preset information database. Specifically, this scheme utilizes vibration reduction schemes stored in the preset information database for each target rotational speed, enabling precise adjustment of the resonance point. The vibration reduction schemes are verified schemes that adjust the amplitude corresponding to the resonance point to a standard range, effectively avoiding vibration mode disturbances caused by mechanical structure and multi-component coupling characteristics. Furthermore, the mechanism of real-time matching of rotational speed and vibration reduction schemes allows vibration reduction adjustment to adapt to different operating conditions, suppressing resonance phenomena at their source, rather than merely superficially optimizing the unbalanced excitation force. This significantly improves the stability and reliability of the vertical condensate pump operation, reduces the risk of system downtime, and ensures the continuity and safety of condensate delivery from the condenser hot well of thermal power units.

[0043] To provide a more detailed explanation of the above embodiments, this application also provides another vibration reduction method for a vertical condensate pump, such as... Figure 3 As shown, the following specific steps are provided in this embodiment of the application:

[0044] Step 301: Obtain the real-time speed of the vertical condensate pump.

[0045] In this step, during the operation of the vertical condensate pump, the real-time rotational speed of the pump is continuously collected by a speed sensor. This real-time speed can be achieved by installing a Hall effect sensor or a photoelectric encoder on the pump shaft or the motor shaft of the vertical condensate pump. The Hall effect sensor utilizes the principle of electromagnetic induction; when a magnetic element on the pump shaft passes by, a pulse signal is generated, and the rotational speed (RPM) can be converted by calculating the number of pulses per unit time. The photoelectric encoder generates pulses by detecting the light transmission and blocking state of a rotating code disk, offering higher accuracy. To improve reliability, a redundant configuration can be used, installing two independent sensors for cross-validation.

[0046] Step 302: Construct a preset information database.

[0047] In this embodiment, the preset information database is obtained through training based on vertical condensate pumps and vibration damping devices. The specific acquisition method is as follows:

[0048] The vibration spectrum data of a vertical condensate pump at different speeds is collected using a stepped frequency sweep test. Based on the peak values ​​in the vibration spectrum data, resonance points and their corresponding amplitude data are determined. A vibration reduction device is used to adjust the amplitude data corresponding to the resonance point at any speed within the corresponding standard vibration data range to obtain a vibration reduction scheme. The stepped frequency sweep test involves dividing the speed range of the vertical condensate pump into multiple continuous sub-intervals, gradually increasing the speed in each sub-interval with a fixed step size, and simultaneously collecting vibration signals. Specifically, a frequency converter can be used to control the motor to drive the pump, combined with an accelerometer to record the vibration spectrum data in real time, thus covering the dynamic response characteristics at different speeds. Vibration spectrum data refers to the frequency domain signal reflecting the vibration energy distribution of the vertical condensate pump, collected by sensors. Specifically, a fast Fourier transform can be used to convert the time-domain vibration signal into frequency domain data, and the resonance point can be identified by analyzing the peak frequencies and amplitudes in the spectrum. The resonance point is a frequency point in the vibration spectrum whose amplitude exceeds a threshold, corresponding to the resonance phenomenon caused by the coupling of the natural frequency of the internal components of the vertical condensate pump with the external excitation frequency. Specifically, the main resonant frequencies can be screened by setting amplitude thresholds or using the peak-valley difference method. Specifically, when constructing the preset information database, vibration spectrum data at different speeds is first obtained through a stepped frequency sweep test, and the resonant frequency and its corresponding amplitude are determined using spectrum analysis. Then, for each resonant point at each speed, the resonance amplitude is gradually reduced until it meets the standard range by adjusting the support force of the vibration damping device, and the motor control parameters during the adjustment process are recorded as the vibration damping scheme. For example, if two resonance peaks are identified at a certain speed, the amplitudes of the primary and secondary resonance points are weakened by adjusting the support force of the lead screw on the outer wall of the water pump, ultimately forming a complete vibration damping strategy for that speed. Compared with existing technologies, existing fine dynamic balancing methods only perform mass balancing on rotating components, which cannot solve the problem of multi-component coupled vibration, and the adjustment process may introduce new resonance points. This scheme comprehensively identifies multiple resonance points through dynamic frequency sweep testing and directly compensates for the resonance amplitude based on real-time adjustment of the support stiffness of the vibration damping device, avoiding the vibration mode shift problem caused by changes in structural parameters. During stepped frequency sweep testing, the test can start from the minimum operating speed of the vertical condensate pump and proceed up to the maximum operating speed, with the speed interval (preset step size) for each test being 1 rpm. For example, tests can be conducted at 300 rpm, 301 rpm, and 302 rpm sequentially to obtain vibration reduction solutions.

[0049] The stepped frequency sweep test includes: dividing the speed range of the vertical condensate pump into multiple continuous speed steps; within any speed step, incremental frequency conversion drive is performed according to a preset speed step size, and vibration spectrum data at different speeds within any speed step size are collected simultaneously. Specifically, the speed step size refers to dividing the speed range of the vertical condensate pump into several continuous and non-overlapping intervals, which can be achieved using equal or unequal division methods, such as dividing the speed range into 50 rpm steps. This division method refines the test range and avoids missing key resonance points due to large speed spans. The preset speed step size refers to the incremental value of each speed adjustment within a single speed step size, which can be achieved using a fixed step size or a dynamically adjusted step size, such as setting it to 5 rpm. This step size setting ensures that the speed increases at small intervals within the step size, thereby accurately capturing changes in the vibration spectrum. Incremental variable frequency drive refers to gradually increasing the speed of a vertical condensate pump by controlling the motor frequency. This can be achieved by using a frequency converter to control the motor's output frequency. This drive method is synchronized with vibration spectrum data acquisition, ensuring that vibration data at each speed point is completely recorded.

[0050] Specifically, in the stepped frequency sweep test, the rotational speed range of the vertical condensate pump is first divided into multiple continuous stepped segments, for example, from 0 rpm to 3000 rpm divided into multiple intervals of 50 rpm. Within a single stepped segment, for example, from 1000 rpm to 1050 rpm, the rotational speed is gradually increased in preset steps of 5 rpm. Each time the rotational speed is adjusted, vibration spectrum data at that speed is immediately collected, for example, by measuring the vibration amplitude and frequency distribution using an accelerometer. Through stepped testing, dense sampling can be performed within each small range, avoiding data loss or test blind spots due to rapid speed changes. Compared to existing technologies, which typically employ continuous frequency conversion or large-range jump tests, uneven speed change rates can easily lead to the failure to identify key resonance points. This solution, through stepped division and step size control, ensures strict matching between speed adjustment and data acquisition, guaranteeing the integrity and continuity of vibration spectrum data, providing a precise data foundation for subsequent vibration reduction schemes. Through the above technical solution, this application can systematically cover the entire speed range of vertical condensate pumps and accurately identify resonance points and amplitude data in different speed steps. This testing method solves the problem of missed resonance points caused by the coarse testing range of existing technologies, provides reliable spectral data support for the adjustment of vibration damping devices, and thus reduces the risk of equipment damage caused by resonance.

[0051] When obtaining a vibration reduction scheme at a certain rotational speed, the resonance point and its corresponding amplitude data at that speed can be obtained first to determine the primary and secondary resonance points. The primary resonance point represents the resonance point corresponding to the maximum amplitude data that does not conform to the corresponding standard amplitude data range. The secondary resonance point represents the resonance point whose amplitude data is lower than the amplitude data of the primary resonance point and is outside the corresponding standard amplitude data range. After determining the vibration reduction scheme for the primary resonance point, the vibration reduction scheme for the secondary resonance point is determined. The vibration reduction schemes for the primary and secondary resonance points are then used to determine the vibration reduction scheme. Specifically, determining the vibration reduction scheme for the primary resonance point can be achieved by adjusting the support force of the lead screw at different positions using a vibration damping device after determining the primary resonance point, and monitoring the amplitude data of the primary resonance point in real time to determine whether the amplitude data is within the corresponding standard amplitude data range. If so, the vibration reduction scheme for the primary resonance point is determined based on the support force of different lead screws in the vibration damping device. The method for obtaining the vibration reduction scheme for the secondary resonance point is the same as that for the primary resonance point, and will not be further limited. Of course, the vibration reduction scheme can also be obtained at once. If the vibration reduction scheme is to be obtained at once, the amplitude data of the resonance point is monitored when the screw support force of the vibration reduction device is adjusted. If the amplitude data is within the corresponding standard amplitude data range, the vibration reduction scheme is determined according to the output of the screw in the vibration reduction device.

[0052] Before adjusting the amplitude data corresponding to the resonance point of the vertical condensate pump at any speed to be within the corresponding standard amplitude data range, the method includes: obtaining the type of the vertical condensate pump and its operating area; determining the vibration damping device and its installation method based on the operating area and the type of the vertical condensate pump; and installing the vibration damping device on the vertical condensate pump based on the installation method. Specifically, the size of the vertical condensate pump is determined according to its model, thereby determining the type of the vertical condensate pump. The operating area of ​​the vertical condensate pump can be measured on-site. Based on the operating area and the type of the vertical condensate pump, the vibration damping device and its installation method are determined, and the vibration damping device is installed on the vertical condensate pump.

[0053] It is worth noting that, in this embodiment, the vibration reduction scheme can also be obtained by: establishing a digital twin model based on the historical operating data and structural parameters of the vertical condensate pump; constructing a virtual model in the digital twin model that highly matches the actual vibration reduction device based on the installation position, installation method, and structural parameters of the vibration reduction device on the vertical condensate pump; simulating the operating conditions of the vertical condensate pump at different speeds using the digital twin model; and adjusting the amplitude data of the resonance point at different speeds using the virtual model to obtain the vibration reduction scheme.

[0054] Specifically, firstly, comprehensive historical operating data of the vertical condensate pump needs to be collected, including real-time speed, amplitude data, temperature, pressure, and other monitoring data, as well as operating log information such as equipment start-up and shutdown times and fault records. Simultaneously, precise data on the equipment's structural parameters, such as pump body material properties (elastic modulus, Poisson's ratio), geometric dimensions (impeller diameter, shaft length), bearing type, and installation location, must be obtained. Using this data, a three-dimensional finite element digital twin model of the vertical condensate pump is constructed based on professional simulation software such as ANSYS and COMSOL. Through material property assignment, boundary condition setting, and mesh generation, the model ensures that it accurately reflects the physical characteristics of the actual equipment. Secondly, based on the technical parameters of the motor, controller, fixed support, and lead screw in the vibration damping device, a virtual vibration damping device is constructed in the digital twin model. Specifically, the motor needs to have its torque-speed curve and dynamic parameters such as moment of inertia defined; the lead screw needs to have its transmission characteristics set, such as pitch, lead, and coefficient of friction; and the fixed support needs to have its mechanical properties, such as material strength and structural stiffness, clearly defined. Simultaneously, based on the actual installation location (outside the vertical drive motor) and installation method (bolt fixing, welding, etc.), a virtual vibration damping device is precisely deployed in the model to ensure its positional relationship and connection method are completely consistent with the actual physical structure. Reasonable constraints are set to realistically simulate the supporting effect of the vibration damping device on the pump body. Next, a digital twin model is used to simulate the operating state of the vertical condensate pump at different speeds (covering startup, normal operation, critical speed, etc.). By simulating the actual operating state of the vertical condensate pump, the vibration characteristics of the pump body under each condition (including data such as the frequency and amplitude distribution of the resonance point) and the analysis results of the operating state are obtained. Finally, based on the above simulation analysis results, the parameters of the vibration damping device are adjusted in the virtual model, such as changing the support force of different lead screws. Multiple sets of parameters are set for repeated simulation experiments to minimize the amplitude data of the resonance point and reduce vibration energy as the optimization objective, thereby obtaining the optimal parameter combination and determining the best vibration damping scheme at different speeds. This digital twin-driven approach to obtaining vibration reduction solutions enables efficient verification and optimization of vibration reduction strategies in a virtual environment, avoiding extensive on-site testing and significantly improving the scientific rigor and effectiveness of vibration reduction solutions.

[0055] Step 303: Based on the matching between the real-time rotational speed and the target rotational speed in the preset information database, if the match is consistent, determine the motor control command based on the corresponding vibration reduction adjustment scheme, and send the motor control command to the controller.

[0056] When the real-time rotational speed matches the target rotational speed, a motor control command is determined based on the corresponding vibration reduction adjustment scheme and sent to the controller to ensure that the amplitude data of the resonance point of the vertical condensate pump at the target rotational speed is within the corresponding standard amplitude data range. If they do not match, it indicates that the amplitude data of the resonance point of the vertical condensate pump at the real-time rotational speed meets the corresponding standard amplitude data range.

[0057] Furthermore, after determining the motor control command based on the corresponding vibration reduction adjustment scheme and sending the motor control command to the controller, the amplitude data of the resonance point of the vertical condensate pump at the target speed is acquired in real time; it is then determined whether the amplitude data of the resonance point is within the corresponding standard amplitude data range; if so, the vibration reduction operation is confirmed to be complete. Specifically, the method for acquiring the amplitude data of the resonance point of the vertical condensate pump at the target speed in real time can be to install an acceleration sensor vertically in the axial bearing seat of the vertical condensate pump, fix it to the measuring point in the middle of the pump body through a magnetic base, connect it to a data acquisition instrument, and set the sampling rate to 2048Hz. After starting the frequency converter to drive the motor to the target speed, the data acquisition instrument captures the vibration time-domain signal in real time, and extracts the amplitude value of the resonance frequency point through FFT transformation. Determining whether the amplitude data of the resonance point is within the corresponding standard amplitude data range can be done by transmitting the data to the DCS control system through a 4-20mA analog signal, plotting the real-time vibration curve on the HMI interface, and marking the standard amplitude data range. When the amplitude of the resonance frequency point is detected to be within the corresponding standard amplitude data range, the vibration reduction operation is confirmed to be complete.

[0058] It is worth noting that after adjusting the resonance point of the vertical condensate pump at the target speed based on the vibration reduction scheme to ensure that the amplitude data meets the standard, this embodiment stores the time and value of the real-time speed of the vertical condensate pump, continuously acquires the real-time speed of the vertical condensate pump, and continuously controls the amplitude of the resonance point of the vertical condensate pump.
