As a key measuring device, mechanical scales play a vital role in industry, commerce and scientific research. In order to ensure its long-term stable operation and measurement accuracy, regular maintenance and care are particularly important.

Flexibility and cleaning of various parts of the scale body
Regularly checking the connection status of various parts of the scale body is an important part of maintaining mechanical scales. In particular, the gap between the limit gap and the ramp and the scale body, the flexibility of these parts directly affects the stability and measurement accuracy of the scale body. Any accumulation of foreign matter or poor connection may lead to a decline in the performance of the scale body. Therefore, these key parts must be cleaned regularly to ensure that there is no accumulation of debris or dust.
The cleaning of the surface of the scale body should not be ignored. Wiping the surface of the scale body with a damp cloth or neutral detergent can effectively remove stains and fingerprints, keeping the equipment clean and beautiful. In this process, avoid using thinners and benzene organic solvents to prevent corrosion to the scale body and affect its service life.

Checking the safety barrier and grounding resistance
The safety barrier is an important safety component of the mechanical scale. Regularly checking the resistance between its intrinsic ground and the grounding rod is a necessary measure to ensure the safe operation of the equipment. In general, the resistance value should be less than or equal to 1Ω. If the resistance value increases, it may be that rust or dust has accumulated at the connection end of the grounding rod or the intrinsic safety busbar of the safety barrier. At this time, these dirt should be removed in time to maintain the intrinsic safety of the system.
In addition, it is necessary to check the resistance between the scale body, the outer shield and the weighing instrument housing to the grounding rod to ensure that its value is less than or equal to 4Ω. This inspection helps to ensure the reliability of the weighing system and prevent measurement errors or equipment damage caused by poor grounding.

Wear inspection and replacement of limit bolts
The limit bolt is one of the core components of the mechanical scale. Its main function is to limit the range of motion of the scale body to prevent damage when it is subjected to excessive impact force. Therefore, it is very important to regularly check the wear of the limit bolts. If severe wear is found, the limit bolts of the same material should be replaced in time to ensure the stability of the scale body and extend its service life.

Maintenance of conveyor belts and weighing sensors
For mechanical scales equipped with conveyor belts, it is necessary to regularly clean up debris and dust on the conveyor belt to prevent affecting the weighing accuracy. At the same time, it is necessary to check the wear of the conveyor belt and replace the severely worn conveyor belt in time to keep it in normal operation.
As the core component of the mechanical scale, the performance of the weighing sensor is directly related to the accuracy of the measurement. Therefore, it is very important to regularly check whether the connecting wires and connectors of the weighing sensor are loose or damaged. If any abnormality is found, it must be repaired or replaced in time to ensure the stability and accuracy of the weighing system.
