Common problems during 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 fasteners are used, regular maintenance is required to ensure safer use of fasteners, extend the service life of fasteners, and improve the performance of mechanical equipment.

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

1. After quenching the fastener, use silicate cleaning agent to remove impurities, and then carefully rinse to avoid leaving impurities on the fastener, thereby affecting its normal use.

2. After the fastener is adjusted, its color may change. After the fastener is soaked in ether for a period of time, an oily substance will be produced, which indicates that the fastener is not clean enough. After analysis, it is found that the accumulation of fasteners during heating is not very reasonable, and the fasteners may have some slight oxidation in the quenching oil.

3. If there is a white substance on the fastener, it may be some phosphide. The reason for this phenomenon is that the acid washer was not used for cleaning and the flushing water tank was not carefully checked.

If these problems cannot be solved 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 fasteners to get up early. And damage. I hope the above three questions can help you make better use of fasteners.
