Bolt plays a role in connection with mechanical equipment. Once the bolt breaks, the damage to the machine will be very large. So how can we take preventive measures to prevent the bolt failure? The fastener network tells you four magic weapons to prevent bolt breakage. Hot dip galvanized bolt mechanical parts, with the cylindrical screw fastener with nut. A type of fastener consisting of the head and screw (cylinder with external thread) which is used to fasten and connect two parts with through holes in coordination with the nut. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection belongs to the detachable connection. High strength bolts are mostly used for the connection of bridges, rails, high-pressure and ultra-high-pressure equipment. The fracture of this kind of bolt is mostly brittle fracture. In order to ensure the sealing of the vessel, the high-strength bolts used in UHV equipment need to be prestressed. Cover assembly link, torque wrench shall be used to tighten according to the standard to prevent excessive torque, too small.
2。 The connecting rod bolts produced by the supporting manufacturer are selected.
3. when the engine oil pan is cleaned and the engine bearing is used, the engine oil pan shall be removed during the second overhaul of 12000km operation. If the clearance of individual bearing shells is too large, replace them and replace connecting rod bolts. If the engine is found to be running irregularly and the noise is abnormal, stop and check it in time.
4. The newly replaced inspection of bolt response of high strength bolt manufacturer of each connecting rod should be noted that the bolt, the guide part, the crack or notch of the thread department, and the head of the tooth pitch are abnormal and the abnormality is determined as whether it is not.
