Troubleshooting the Cracking Fault of a Diesel Engine Isolator
In response to the cracking failure of a vehicle diesel engine shock absorber,the shock absorber was investigated and ana-lyzed item by item from the aspects of design selection,assembly,and use environment to determine the cause of the failure.After in-vestigation,the main reason for the cracking of the shock absorber surface was that after being eroded by oil,the rubber swelled,resul-ting in a decrease in the mechanical properties of the shock absorber.At the same time,due to the failure to promptly correct the in-stallation dimensions of the shock absorber,individual shock absorbers suffered from large alternating stresses,further deteriorating the working environment of the shock absorber.Under the combined effects of long-term alternating and pitching forces,the cracking fail-ure of the shock absorber surface eventually occurred.In response to the above failure causes,the company requires maintenance per-sonnel to take effective protective measures during maintenance and overhaul.At the same time,operators are also required to regularly check the surface cleanliness and installation status of the shock absorber to ensure that the failure does not occur again.
