Drain plug maintenance matters needing attention
Introduction:
Oil drain plugs are widely used in major machinery and equipment, and are closely related to the performance of mechanical equipment. If the oil drain plug is suddenly damaged during use, it may seriously damage the equipment and cause the equipment to fail to operate normally. Therefore, we In the process of using the oil drain plug, it is best to carry out the maintenance of the situation, so as to use it more safely.
When using and maintaining the oil drain plug, you need to pay attention to the following six problems:
1. The process of rinsing the oil drain plug is very important and needs to be very careful. During this process, there will be residues left on the surface of the oil drain plug. Rinse This step is to be done after cleaning with silicate cleaning agents.
2. The oil drain plug 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.
