Description

Technical Field

[0001] The utility model relates to the technical field of vibration analyzers, in particular to a handheld color-screen vibration analyzer. Background Art

[0002] The handheld color screen vibration analyzer is a portable instrument used to detect and analyze the vibration status of mechanical equipment. It helps engineers and maintenance personnel diagnose equipment failures, predict equipment life, and perform preventive maintenance by measuring and recording vibration signals. The handheld color screen vibration analyzer needs to be operated by personnel who are trained and familiar with the operation to play the best role. If the operator's skills are insufficient, he may not use the instrument correctly or misoperate it, resulting in inaccurate results. During operation, connect the sensor of the handheld color screen vibration analyzer to the equipment under test for data collection. During the data collection process, it is necessary to pay attention to the location of the sensor, the installation method, and the connection status between the sensor and the equipment under test to ensure the accuracy of the collected data.

[0003] The sensor should be located at a critical part of the equipment being tested, usually close to bearings, drive components, or other parts that may generate vibration. Choosing a suitable location can more accurately reflect the vibration of the equipment and help accurately diagnose the operating status of the equipment.

[0004] In addition, attention should be paid to the direction of the sensor, which should be consistent with the vibration signal of the device under test. For example, if the device generates axial vibration, the sensor should be placed in a direction parallel to the axis; if the device generates radial vibration, the sensor should be placed in a direction perpendicular to the axis. This can maximize the acquisition of the intensity and frequency characteristics of the vibration signal.

[0005] As well as the installation angle of the sensor, in order to find the maximum vibration response position on the device under test. By adjusting the angle of the sensor, it can be sensitively captured to the maximum vibration amplitude and frequency. This helps to more accurately identify the failure mode and vibration characteristics of the equipment.

[0006] The sensor end of an existing vibration analyzer is generally connected to the device under test via a magnet. It is inconvenient to repeatedly disassemble the sensor when adjusting the position, and the position is not accurate enough.

[0007] To this end, we propose a handheld color screen vibration analyzer. Utility Model Content
