How to prevent bolt fracture effectively

The bolt mainly plays a connecting role in mechanical equipment. Once the bolt breaks, the damage to the machine will be very large. Therefore, how can we take preventive measures against the occurrence of bolt failure? The fastener network tells you four magical weapons to prevent bolt breakage. Hot dip galvanized bolt mechanical parts, cylindrical threaded fasteners with nuts. A kind of fastener composed of head and screw (cylinder with external thread), which is used to connect two parts with through-hole by matching with 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 is a 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 brittle fracture. High strength bolts used in ultra-high pressure equipment need to be prestressed in order to ensure the sealing of vessels. Cover assembly link, apply torque wrench, tighten according to standard to prevent excessive torque, too small.

2。 Connecting rod bolts produced by supporting manufacturers are selected.  
3. The engine oil pan should be removed and the service condition of engine bearing should be checked when the secondary maintenance is conducted every 12000km. If the clearance of individual bearing bush is too large, it should be replaced and the connecting rod bolt should be replaced at the same time. If the engine runs unevenly and the noise is abnormal, it should be stopped and checked in time.
4. New replacement inspection of each connecting rod high strength bolt manufacturer's bolt response maintenance should pay attention to that the bolt, the guide part, the thread Department crack or notch, the head of the tooth pitch is abnormal, and the abnormality is determined as No.
The company's main business: high strength bolt, high strength nut, steel structure bolt, steel structure nut, grid sealing plate, grid bolt, etc.
