Mechanical scales play an important role in many fields such as industry, commerce and laboratories. Although their structure is relatively simple, mechanical scales will inevitably encounter mechanical wear during long-term use. Wear not only affects the weighing accuracy and service life of the scale, but may also cause safety hazards. Therefore, it is particularly important to deal with mechanical wear problems in a timely and effective manner.

Comprehensive inspection and evaluation
The first step in dealing with mechanical wear is to conduct a systematic inspection and evaluation of the mechanical scale. Regular inspections can detect potential wear problems early so that corresponding maintenance measures can be taken. During the inspection process, the following key aspects should be paid attention to:
Visual inspection: Through visual inspection, observe the overall appearance of the mechanical scale and look for obvious signs of wear, cracks or deformation.
Precision measurement: Use professional measuring tools such as vernier calipers and micrometers to measure the dimensional changes of key components. For example, check the length of the lever, the elasticity of the spring, etc. to ensure that they meet the design specifications.
Functional test: Perform functional tests to ensure the weighing accuracy of the mechanical scale under different loads. Calibration can be performed using standard weights to observe the consistency and accuracy of the readings.
Through the above inspection, the degree of wear can be effectively evaluated and whether further maintenance or replacement is required.

Cleaning and Lubrication
After confirming the existence of wear, cleaning and lubrication are important links in dealing with wear problems. Regular cleaning can remove dirt, dust and corrosive substances, thereby reducing the occurrence of wear. Lubrication can reduce the friction coefficient and extend the service life of each component.
Cleaning: Use appropriate cleaning agents and tools to thoroughly clean the various components of the mechanical scale, especially areas such as levers, fulcrums and springs that are prone to dirt accumulation.
Lubrication: According to the requirements of different components, choose a suitable lubricant for lubrication. The selection of lubricants should take into account factors such as working environment, temperature and load. Regular lubrication can significantly reduce wear and improve the overall performance of the mechanical scale.

Adjustment and Calibration
In the case of wear, the mechanical scale may have weighing deviations, so adjustment and calibration are required.
Adjustment: For slightly worn parts, adjustments can be made to restore their original functions. For example, adjust the balance of the lever to ensure that it can accurately transmit force when weighing.
Calibration: After completing the adjustment of the components, calibration must be performed. Calibration is performed using standard weights to ensure that the mechanical scale reads accurately under different loads. Calibration should be performed regularly to ensure reliable weighing.

Part Replacement
For severely worn parts, cleaning and lubrication alone may not restore their performance, and part replacement is required.
Identify worn parts: Based on the results of inspection and evaluation, identify the parts that need to be replaced, such as springs, levers, bearings, etc.
Select replacement parts: Select high-quality replacement parts for replacement and ensure their compatibility with the original parts. High-quality replacements can significantly improve the overall performance and service life of the mechanical scale.
Installation and commissioning: After replacing the parts, install them according to the manufacturer's instructions and perform necessary commissioning to ensure that the new parts work properly.
