Fasteners such as U-bolts are the most widely used parts
Fasteners such as U-shaped bolts and American-made bolts are the most widely used parts. Some fasteners can be found in various machinery, equipment, vehicles, ships, instruments, meters and supplies. Fasteners are characterized by a wide range of specifications, different functions, and standardization, which have also become standard parts. Fasteners are the most widely used mechanical basic parts. Follow China into the ranks of major international trade countries. Many Chinese fastener products are exported to countries around the world, and fastener products from all over the world are also pouring into Chinese business markets. Fasteners, as one of China’s large import and export commodities, are in line with international standards, which are of great practical significance to promote Chinese fastener companies to the world and promote fastener companies to participate in international cooperation and competition Strategic significance. China's fastener industry will still face continued pressure and challenges, but at the same time it has also accelerated the reshuffle of the industry and the survival of the fittest, which is conducive to improving industrial concentration, promoting the advancement of skills, optimizing the development model, and making the company more focused on enhancing autonomy. Innovative ability and core competence.
Precautions you must know when using U-bolts
U-shaped bolts play an important role in the connection of mechanical equipment, so attention should be paid to these parts and their role cannot be ignored. Today, I will talk to you about the precautions you must know when using U-bolts.
1. When running 12000km for secondary maintenance, the engine oil pan should be disassembled to check the use of the engine bearing bush. If the clearance of individual bearing bush is found to be too large, it should be replaced, and the connecting rod bolt should be replaced at the same time. If you find that the engine is running unsteadily or abnormal noise during normal operation, you should stop and check in time.
2. The newly replaced connecting rod bolts should be inspected during each maintenance, and attention should be paid to whether there are cracks or dents on the head, guide part, and thread parts of the bolt, and whether the tooth shape and pitch of the thread are abnormal. If there are abnormal conditions, they should be resolutely not used.
3. When assembling the connecting rod cover, use a torque wrench to tighten it according to the specified standard to prevent excessive or small torque.
4. Use connecting rod bolts produced by supporting factories.
