Problems needing attention in screw maintenance

Publish time: 24 Oct 22

Micro screws are widely used in major mechanical equipment, and have a close relationship with the performance of mechanical equipment. If the screw is suddenly damaged during use, it may seriously damage the equipment and cause the equipment to fail to operate normally. Therefore, we are using the screw process. In order to use it more safely, it is best to carry out fixed maintenance.

When using and maintaining screws, you need to pay attention to the following six problems:

1. The process of rinsing the screw is very important and needs to be very careful. During this process, there will be residues left on the surface of the screw. Rinse This step is to be done after cleaning with silicate cleaning agents.

2. The screws should be stacked together during the tempering and heating process, otherwise it will cause slight oxidation in the quenching oil.

3. White residues of phosphide will appear on the surface of the high-strength screw, indicating (point 1) that the inspection is not careful enough during operation.

4. There will be blackening on the surface of the parts, resulting in chemical reaction, indicating that the work in the heat treatment is not done well and the alkaline residue on the surface is not completely removed.

5. The standard parts of the parts will rust during rinsing, and the water used for rinsing should also be replaced frequently.

6. Excessive corrosion indicates that the quenching oil has been used for too long, and new oil needs to be added or replaced.
