How to effectively prevent bolt breakage
Bolts mainly play a connecting role in mechanical equipment. Once a bolt breaks, it will cause significant damage to the machine. Therefore, how can we take preventive measures to prevent bolt failures? The fastener network tells you four magical weapons to prevent bolt breakage. Hot dip galvanized bolt Machine element, cylindrical threaded fastener with nut. A type of fastener consisting of a head and a screw (cylindrical body with external threads), which needs to be matched with a nut to securely connect two parts with through holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, it can separate these two parts, so bolt connection is a detachable connection. High strength bolt manufacturers often use high-strength bolts for the connection of bridges, steel rails, high-voltage and ultra-high voltage equipment. The fracture of this type of bolt is mostly brittle. High strength bolts applied to ultra-high pressure equipment require significant prestressing to ensure the sealing of the container. Cover the component link and apply a torque wrench to tighten according to the standard to prevent excessive torque from being too small.
2. Select connecting rod bolts produced by matching manufacturers.
3. During the secondary maintenance of each 12000 km operation, the engine oil pan should be cleaned and the usage of the engine bearings checked. If individual bearing shells are found to have excessive clearance, they should be replaced, and the connecting rod bolts should also be replaced. If the engine is found to run unevenly and the noise is abnormal, it should be stopped and checked in a timely manner.
4. For the maintenance of each high-strength bolt manufacturer's bolt response for the newly replaced connecting rod, it should be noted that the bolt, the guide part, the thread department, cracks or gaps, and the head of the tooth pitch are abnormal, and the abnormality is determined as not.
