Fasteners are screws, nuts, washers, etc. used to fasten two or more objects. It is widely used in machinery, construction, aviation, automobile and other fields. Due to its important role in machinery, maintenance and replacement become crucial. Below, maijin will show you how to maintain and replace fasteners. 1. How to maintain fasteners Pay attention to the surface cleaning of fasteners: if the surface of fasteners is dirty or corroded, it will affect their fastening performance and life, so keeping the surface of fasteners clean is the Critical. Check the tightening force of fasteners: Due to the variety of working conditions, fasteners need to be inspected at least once a year. This can ensure that the fasteners are not loose or damaged. Fasteners of different materials need to be inspected at different intervals. The use of covering agent: the use of some covering agent can prolong the life of fasteners. For example, Dutch plate material is used to reduce wear between fasteners and machine surfaces. Do not reuse partitions: partitions fail to judge their reusability. Some separators may lose their original strength and adhesion after one use, which can lead to wear or pitting of fasteners if forced. Removal of waste material: When performing maintenance and repairs on fasteners, all waste materials need to be removed. If some scrap isn't cleaned out, it could cause it to get caught in the middle of the fastener, causing loosening or other problems. 2. How to replace the fasteners Turn off the equipment: When replacing the fasteners, the equipment must be turned off first. Failure to do so may cause the fastener to become unstable, resulting in erratic equipment operation or an emergency shutdown. Locating fasteners: Find the location of the fasteners that need to be replaced according to the design drawings or instructions of the equipment. Removing the existing fasteners: Use a suitable tool to remove the fasteners that need to be replaced. If they are screws or nuts, they need to be turned counterclockwise until they are completely removed. Replacing new fasteners: When purchasing new fasteners, factors such as their material, model and size need to be considered. Proper installation of fasteners is critical. Improper installation can result in damaged fasteners or unstable equipment. Repeated inspection: After replacing the fasteners, repeated inspections are required. For each fastener, they should be inspected for adequate tightness and for any looseness or corrosion. In short, the maintenance and replacement of fasteners must be carried out. This ensures their tightness and the stability of mechanical components, prolongs the life of fasteners, and improves the safety and reliability of equipment.
