Fasteners in the repair process will encounter what problems

2024-06-26

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

What problems do we often have when maintaining fasteners? There are three main problems

1. When the fastener is quenched, it is necessary to clean the impurities on it with silicate cleaning agent, and then wash it carefully to avoid leaving impurities on the fastener and affecting its normal application.

2. After tempering, the color of the fastener may change. After soaking the fasteners in ether for a period of time, there will be oily substances. This indicates that the fasteners are not clean enough. After analysis, it will be found that the stacking of fasteners during heating is not very reasonable, and some small oxidation of fasteners may occur in the quenching oil.

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

If these problems can not be dealt with in time, it will directly affect the performance of the fastener, and may also lead to the shortening of the service life of the fastener, resulting in the phenomenon of early damage of the fastener. I hope the above three questions can help you make better use of fasteners.

Explanation of the method of avoiding slippage of standard nut parts

The method of avoiding slippage of standard nut parts is explained. It is mainly distinguished by the thread on the inside. The standard nut part is the nut, which is screwed together with the bolt or screw to play a fastening role. It is a kind of original that must be used in all manufacturing machinery. The standard nut part is the part that tightly connects the machinery and equipment. Through the thread on the inside, the lock nut and screw of the same specification can be connected together. The following describes in detail the two ways to avoid slippage of the standard nut parts.
