[0035] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0036] The first implementation method:

[0041] A sealing cover is detachably installed at the opening of the dust-free box 31, and the sealing cover is used to seal the dust-free box 31. A magnetic levitation sealed bearing 6 matching the test rotor 4 is installed in the sealing cover; the magnetic levitation sealed bearing 6 includes a stator and a rotor, and a docking seat 61 matching the round head clamping shaft 41 is installed on the rotor; a hexagonal groove is provided on the docking seat 61, and a hemispherical docking groove matching the round head clamping shaft 41 is provided in the middle of the hexagonal groove; the main body of the magnetic levitation sealed bearing 6 is the existing technology, and the stator and rotor have the same structure as the magnetic levitation bearing of the existing technology, and it can be suspended in a dust-free environment after being powered on.

[0042] The magnetic levitation sealed bearing 6 is used to close the sealing cover, and is also used to test the calibration and auxiliary reset of the rotor 4; a terminal block is provided on the sealing cover, and the side end of the test box 3 is fixedly connected to a control box electrically connected to the distribution cabinet 2, and the control box and the terminal block are connected by a detachable wire, and the terminal block is used to connect the magnetic levitation sealed bearing 6 and the magnetic levitation bearing to be tested; after the magnetic levitation bearing to be tested is installed on the fixed frame 5, the magnetic levitation bearing to be tested is connected to the terminal block, the control box is started, and the magnetic levitation sealed bearing 6 and the magnetic levitation bearing to be tested are powered through the distribution cabinet 2.

[0043] When the test box 3 is working, the test rotor 4 penetrates the magnetic bearing to be tested, and the round head clamping shaft 41 matches with the docking seat 61;

[0044] An electric telescopic rod 7 is fixedly connected to the inner wall of the dust-free box 31, and a clamping mechanism is connected to the power output end of the electric telescopic rod 7.

[0045] The clamping mechanism includes a support plate 8, and the support plate 8 is rotatably connected to the top end of the telescopic end of the telescopic shaft 33. A connecting seat matching the support plate 8 is installed on the telescopic end of the electric telescopic rod 7. A pair of clamping claws 81 are slidably connected to one end of the support plate 8 close to the fixing frame 5. A cylinder 82 matching the clamping claws 81 is installed on the support plate 8; a clamping block is fixedly connected to the top end of the clamping claw 81, and a high-precision force sensor is installed on the clamping block. A groove matching the clamping block is opened at one end of the test rotor 4; the clamping mechanism is used for fixing and recovering the test rotor 4; the clamping mechanism drives the clamping claws 81 to clamp the test rotor 4 through the cylinder 82;

[0046] The clamping mechanism keeps clamping the test rotor 4 until the hemispherical docking groove docks with the round head clamping shaft 41, and then powers the magnetic suspension sealed bearing 6 and the magnetic suspension bearing to be tested. Then the clamping mechanism releases the test rotor 4 and resets it. At this time, the offset of the test rotor 4 is detected, and the current of the magnetic suspension sealed bearing 6 and the magnetic suspension bearing to be tested is adjusted to adjust the suspension state of the test rotor 4 until the test rotor 4 is coaxial with the magnetic suspension sealed bearing 6. In this way, the test rotor 4 is positioned and calibrated. The position of the test rotor 4 at this time is used as the standard position. In subsequent tests, the displacement of the test rotor 4 relative to the standard position is the offset.

[0047] Before calibrating the test rotor 4, adjust the fixing frame 5 so that the electric extension rod 53 and the lifting platform 52 make the magnetic suspension shaft to be tested coaxial with the magnetic suspension sealed bearing 6;

[0048] After the test rotor 4 is calibrated, the clamping mechanism clamps the test rotor 4 and pulls the test rotor 4 backwards, so that the round head clamping shaft 41 is separated from the hemispherical docking groove;

[0049] A detector is provided between the support plate 8 and the fixing frame 5, and a laser sensor for detecting the deviation of the test rotor 4 is installed on the detector;

[0050] The support plate 8 is used to clamp the test rotor 4. By controlling the displacement of the support plate 8 and the operation of the clamping jaws 81, the test rotor 4 can be recovered after installation. The detector records the offset data in real time and transmits it to the control box, which analyzes the data and adjusts the parameters of the magnetic bearing.

[0051] The detector includes a movable bracket, which adopts an electrically controlled adjustment bracket in the prior art, and a C-shaped bracket 9 is fixedly connected to the power output end of the movable bracket. A person skilled in the art uses a suitable movable bracket in the prior art to install the movable bracket so that the movable bracket can be automatically adjusted to achieve that the C-shaped bracket 9 covers the test rotor 4; a laser sensor is installed on the C-shaped bracket 9 for accurately measuring the operating state and offset of the test rotor 4;

[0052] The laser sensor is installed on the inner wall of the C-frame 9; the laser sensor is a prior art, and a technician in this field can select a suitable laser sensor in the prior art for installation, such as a laser ranging sensor and a laser interferometer sensor; the C-frame 9 can adjust its position according to the test requirements to ensure that the laser sensor is accurately aligned with the test rotor 4, ensuring the accuracy and reliability of the test data.

[0053] A through hole is opened in the middle of the support plate 8, and a plug rod 331 matching the through hole is inserted into the telescopic end of the telescopic shaft 33, and an electromagnet 332 matching the plug rod 331 is installed in the telescopic end of the telescopic shaft 33, and a permanent magnet is arranged in the plug rod 331;

[0054] When testing the magnetic bearing, the test rotor 4 is first installed. During installation, the electromagnet 332 works and repels the permanent magnet, so that the insertion rod 331 moves forward, thereby pushing the test rotor 4 to move to the magnetic bearing to be tested.

[0055] Auxiliary equipment is provided at the lower side of the test area, including a fan 10 installed on the cabinet 1, an air inlet pipe and an exhaust pipe are installed at the lower end of the dust-free box 31, the air inlet pipe is communicated with the fan 10, and a refrigerator and a heater are installed on the fan 10, and an exhaust pump is connected to the exhaust pipe. The fan 10 adopts the existing technology, and the fan 10 can input the airflow of the set temperature into the test box 3 through the refrigerator and the heater to simulate the test environment of different temperatures;

[0056] The auxiliary equipment is used to adjust the ambient temperature in the test box 3. The airflow of set temperature is introduced into the test box 3 through the fan 10 to adjust the temperature in the test box 3 so as to test the working state of the magnetic bearing under different temperature environments.

[0057] When the present solution is working, the test rotor 4 rotates under the action of the motor 32, and then the working test of the magnetic bearing is performed; the telescopic function of the telescopic shaft 33 enables the test rotor 4 to flexibly adjust its position to meet the testing requirements of magnetic bearings of different sizes;

[0058] During the test, the laser sensor detects the offset of the test rotor 4 in real time. This data is crucial for evaluating the suspension accuracy and stability of the magnetic bearing. If the offset is detected to exceed the preset threshold, the system will automatically record and alarm, prompting the operator to check and adjust.

[0059] In addition, the design of the support plate 8 makes the installation and recovery process of the test rotor 4 more convenient and efficient. By controlling the extension and contraction of the cylinder 82, the clamp 81 can firmly clamp the test rotor 4 to ensure its stability and safety during the installation and recovery process; when testing, the clamp 81 loosens the rotor 4;

[0060] In the test process, a small displacement excitation can be applied to the test rotor 4 by controlling the displacement of a single clamp 81. At this time, the high-precision force sensor on the clamp 81 detects the reaction generated, and the stiffness of the magnetic bearing is calculated according to the relationship between force and displacement. The design of the clamping mechanism is not only used to fix the test rotor 4, but also to perform displacement excitation during the test, so as to perform stiffness testing.

[0061] In addition, this solution can also perform other magnetic bearing tests in the prior art, such as power consumption test: measuring the input power of the magnetic bearing system under different working conditions;

[0062] Temperature characteristic test: During the long-term operation of the magnetic bearing, a temperature sensor is used to monitor the temperature changes of various components in the magnetic bearing in real time.

[0063] Electromagnetic compatibility test: evaluate the anti-interference ability of the magnetic bearing system in the electromagnetic environment and the electromagnetic radiation level to the surrounding equipment; technicians in this field can set up electromagnetic interference sources in the prior art in the test box 3 for testing, such as radio frequency interference, electrostatic discharge, etc., to test whether the working stability and performance of the magnetic bearing system are affected. Through these comprehensive tests, the performance and reliability of the magnetic bearing can be fully evaluated;

[0064] The static test platform of this scheme facilitates the multi-directional testing of magnetic bearings; by simulating the actual working environment and load conditions, it is easy to adapt to the testing of different types of magnetic bearings.

[0065] Second implementation method:

[0066] Figure 8 As shown, an auxiliary test system is also included, the auxiliary test system includes a processor installed in the power distribution cabinet 2, and the processor is connected to a control module, a data processing module, a data storage module and a monitoring module;

[0067] The monitoring module is used to collect monitoring data and equipment status during the test process. The monitoring data includes: data collected by laser sensors, high-precision force sensors and temperature sensors; the module can detect abnormal conditions in time and send out alarm signals to prompt operators to check and adjust; temperature sensors are installed in the fixed frame 5 and the dust-free box 31;

[0068] The control module is used to control the operation of the static test platform, including controlling the working status of the motor 32, the electric telescopic rod 7, the clamping mechanism and the fan 10, and controlling various parameter settings during the test, such as the test time, the test temperature, etc.; through the control module, the operator can easily achieve comprehensive control over the test process.

[0069] The data processing module is used to process the monitoring data, and determine the rotation speed, offset and temperature of the test rotor 4 by processing the monitoring data; the data processing module can process the monitoring data in real time, calculate the suspension accuracy, stability, stiffness and other performance indicators of the magnetic suspension bearing to be tested, and present the processing results in the form of charts, reports, etc. for reference and analysis by operators.

[0070] The data storage module is used to store all data during the test, including monitoring data, processing results and historical records, etc. This module has the characteristics of large capacity, high reliability and easy query, which can ensure the security and integrity of the test data.

[0071] The various modules of the auxiliary test system work together to achieve all-round and high-precision testing of magnetic bearings.

[0072] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
