Description

Technical Field

[0001] The utility model relates to the technical field of equipment fault generators, in particular to a rotating equipment fault generator. Background Art

[0002] Rotating equipment fault generator is an instrument used to monitor, detect and diagnose the operating status of rotating equipment (such as motors, pumps, fans, compressors, etc.). The device mainly identifies and predicts possible faults by real-time monitoring and analysis of various operating parameters (such as vibration, temperature, pressure, current and voltage, etc.), thereby ensuring the reliable operation of rotating equipment.

[0003] Most existing detection methods usually rely on a single type of sensor, such as accelerometers or basic vibration sensors. Data recording and analysis also rely on manual operations, which are inefficient and prone to errors. There is a lag in monitoring and maintenance responses, resulting in low equipment efficiency and frequent failures. At the same time, due to the limitations of monitoring methods, it is difficult to detect and deal with potential failures in a timely manner, and there are major safety hazards and other problems. This results in insufficient accuracy in many aspects, making it impossible to capture early minor failures, causing small problems to gradually evolve into major failures, affecting product quality.

[0004] In view of the above, the present application proposes a rotating equipment fault detector to solve the above problems, improve the operating efficiency and reliability of the equipment, and greatly reduce maintenance costs through preventive and predictive maintenance, extend the service life of the equipment, improve the overall production efficiency and safety, and improve product stability.

[0040] The present application proposes a rotating equipment fault generator, which is specifically as follows:

[0041] For reference Figure 1-2The present application is mainly composed of a support bracket 1, a driving member 2 arranged on the bracket 1 for providing driving force, a main shaft 3 that supports and transmits a working area 4, and a stabilizing shaft 5 that supports the auxiliary main shaft 3 for stable operation. Through the coordination of the work between the individual components, early fault detection and diagnosis of rotating equipment can be achieved to ensure stable operation and maintenance of the equipment.

[0042] For reference Figure 1-2 The bracket 1 is used to support the driving member 2, the main shaft 3, the working area 4 and the stabilizing shaft 5; the bracket 1 is mainly composed of a chassis 11 and a bottom shaft 12, and the upper surface of the chassis 11 is horizontally installed to install and support the driving member 2, the main shaft 3, the working area 4 and the stabilizing shaft 5; the specific external shape of the chassis 11 is not limited and can be adjusted according to the required environment, as long as it meets the supporting function during work; the bottom shaft 12 is arranged at the bottom of the chassis 11, which helps to evenly distribute the load on the mounting plate, reduce single-point force, prevent local stress concentration, and thus extend the service life of the equipment.

[0043] For reference Figure 1-2 The driving part 2 is used for the output of electric energy of the equipment and is connected to the main shaft 3 for operation. It mainly includes a frequency converter 21, a motor group 22 and a coupling 23; the frequency converter 21 is fixedly mounted on the upper surface of the chassis 11, the motor group 22 is located near the frequency converter 21 and is fixedly mounted on the chassis 11, and the coupling 23 is mounted on the output end of the motor group 22 for transmitting the torque of the motor group 22 to the main shaft 3; the frequency converter 21 is connected to the power supply and the motor group 22, so as to adjust the input voltage and frequency of the motor group 22 and control the speed and torque of the motor group 22, and the motor group 22 is connected to the main shaft 3 through the coupling 23, and the electric energy is converted into mechanical energy to drive the main shaft 3 to rotate; the coupling 23 maintains a certain axial and radial displacement in the middle to reduce the influence of the alignment error on the system.

[0044] To further explain, the motor group 22 includes a mounting frame 221 and a motor 222. The mounting frame 221 is installed on the chassis 11, and the motor 222 is installed on the mounting frame 221. The motor 222 is raised by the support of the mounting frame 221 to enable the structures installed in the working area 4 to maintain a moving distance from the chassis 11.

[0045] For reference Figure 1-2 The working area 4 is fixedly installed on the main shaft 3 for the inspection of the equipment fixation, wherein the working area 4 is provided with a first sensor 41, an eddy current probe bracket 42, a test weight plate 43, a second sensor 44 and a key phase bracket 45 in sequence starting from the side close to the coupling 23;

[0046] The first sensor 41 is a sensor of model JNJVS5500, installed on the spindle 3; it is mainly used to detect the vibration, displacement, speed and other parameters of the spindle 3, and provide data on the running status of the spindle;

[0047] The eddy current probe bracket 42 is fixed on the main shaft 3 and is used to install the eddy current probe to ensure that it can accurately measure the displacement and vibration of the main shaft surface;

[0048] The test weight plate 43 is fixed on the main shaft and is used for balance testing and calibration to simulate the load conditions under actual working conditions;

[0049] The second sensor 44 adopts a sensor model JNJVS5500-08, which provides accurate displacement and vibration measurement data for monitoring the operating status of the spindle;

[0050] The key phase bracket 45 is installed on the main shaft and is used to install the key phase sensor to detect the angular position and synchronization signal of the main shaft.

[0051] In the specific implementation of the inspection of rotating equipment failures, inspections are carried out from the perspectives of vibration and displacement monitoring, data acquisition and analysis, angle position and synchronization signals, and load simulation and calibration;

[0052] Vibration and displacement monitoring: The vibration and displacement of the main shaft are monitored in real time by the first sensor 41 and the second sensor 44. The data of the sensors can be used to identify abnormal vibration and displacement patterns and determine whether there is a fault. The eddy current probe is installed on the eddy current probe bracket 42 to measure the tiny displacement and vibration of the main shaft 3 surface, and obtain accurate data through the eddy current effect.

[0053] Data collection and analysis: The data is transmitted to an external control system or computer through the collection system of the first sensor 41 and the second sensor 44. The external control system or computer identifies abnormal vibration and displacement patterns by analyzing the sensor data and determines whether there is a fault, such as bearing wear, spindle misalignment, etc.

[0054] Angle position and synchronization signal: A key phase sensor is installed on the key phase bracket 45 to detect the angle position and synchronization signal of the main shaft, ensure the synchronization and accuracy of data collection, and assist in fault location and diagnosis.

[0055] Load simulation and calibration: The test weight plate 43 is used to simulate the load condition under the actual working state for balance test and calibration to ensure the stable operation of the spindle 3 under the actual working condition.

[0056] For reference Figure 3-4In order to ensure stability during use, a stabilizing shaft 5 is provided at the end of the main shaft 3 away from the driving member 2; the stabilizing shaft 5 is mainly composed of a blocking flange 51, a bearing seat 52, a ball bearing 53 and a retaining spring 54; the blocking flange 51 is provided at the end of the main shaft 3 away from the driving member 2, and plays a role in preventing the main shaft 3 from axial movement and ensuring the stability of the main shaft 3; the bearing seat 52 is provided at the end of the main shaft 3 close to the blocking flange 51; it plays a role in supporting the main shaft 3 and the output end of the driving member 2 to be flush and provide stable rotation support; the inner ring of the ball bearing 53 cooperates with the main shaft 3, and the outer ring is fixed to the bearing seat 52, so as to reduce friction and ensure the smooth operation of the main shaft; the retaining spring 54 fixes the ball bearing 53 in the axial position to prevent the bearing from moving on the main shaft 3 and ensure the stable connection between the ball bearing 53 and the main shaft 3.

[0057] In the utility model, the working steps of the device are as follows:

[0058] 1. First, the frequency converter 21 is powered on, and adjusts the input voltage and frequency of the motor according to preset parameters, and starts the motor 222. The motor 222 starts to rotate under the control of the frequency converter 21, converting electrical energy into mechanical energy. The output end of the motor 222 is connected to the main shaft 3 through the coupling 23, and the coupling 23 transmits the rotation torque of the motor 222 to the main shaft 3;

[0059] 2. Secondly, driven by the motor 222, the main shaft 3 starts to rotate, and all the fixed components on the main shaft (i.e., the working area 4) rotate together, and during the rotation, the stabilizing shaft 5 achieves a stable supporting force at the end;

[0060] 3. Then, the working area 4 performs real-time monitoring and data collection during the rotation process, and transmits the collected data to the external data collection system for real-time monitoring. The external data collection system analyzes the data, identifies abnormal vibrations, displacement patterns and changes in angular position, and determines whether there are mechanical faults, such as imbalance, bearing wear, spindle misalignment, etc.;

[0061] 4. Finally, based on the data analysis results, the system sends out an early warning signal to notify maintenance personnel to inspect and maintain the equipment to prevent failures.
