Common problems in fastener maintenance

Although the fastener is a small part, it is an indispensable part of mechanical equipment and also plays a very important role. Therefore, when we use fasteners, we need to carry out regular maintenance, so as to ensure the safer use of fasteners, and can extend the service life of fasteners and improve the performance of mechanical equipment.

When we are maintaining fasteners, what problems often occur? There are three main problems:

1. When the fastener is quenched, use a silicate cleaning agent to clean up the impurities, and then rinse carefully to avoid leaving impurities on the fasteners, affecting its Normal application. (Guide: Four common series of self-locking nuts)

2. After the fastener is tempered, its color may change. After the fastener is soaked in ether for a period of time, oily substances will be produced. Such a situation indicates The fasteners are not clean enough. After the analysis, it will be found that the stacking of fasteners is not very reasonable when heating the fasteners, and the fasteners may have some small oxidation phenomena in the quenching oil.

3. If there is a white substance on the fastener, it is likely to be some phosphide. The reason for this phenomenon is that the acid cleaning machine is not used for cleaning, and the rinsing tank is not carefully checked.

If these problems cannot be dealt with in time, they will directly affect the performance and use of the fasteners, and may also shorten the service life of the fasteners and cause the phenomenon of early damage to the fasteners. I hope that the above three issues can help you make better use of fasteners.
