During long-term use, springs are prone to permanent deformation, fracture, rust, fatigue attenuation and other faults due to repeated loads and environmental conditions. Timely troubleshooting and daily maintenance can extend the service life of springs and avoid equipment shutdown due to spring failures. The following are common faults and targeted solutions for five types of springs.
Common fault one: permanent deformation, manifested as the inability to restore the original state after external force is removed, often caused by the load exceeding the elastic limit of the spring, material fatigue, and inadequate heat treatment. Solution: Replace the spring with a stronger load-bearing capacity and qualified material to ensure that the load does not exceed the elastic limit; Regular inspection and timely replacement of fatigue aged springs.
Common Fault 2: Fracture, manifested as the spring breaking under stress, often caused by material defects, thin wire diameter, excessive load, corrosion and aging. Solution: Investigate the cause of the fracture, replace the spring with a material that is qualified, has a suitable wire diameter, and meets the load-bearing capacity standards; Replace stainless steel springs or perform rust prevention treatment in corrosive environments; Avoid overloading during use.
Common fault three: rust and corrosion, manifested as rust stains and corrosion spots on the surface of the spring, often caused by humid working conditions, lack of rust prevention treatment or failure of rust prevention treatment. Solution: Slight rust can be treated with grinding, rust remover, and a new anti rust coating; Severe corrosion requires direct replacement; Stainless steel springs are preferred for humid and corrosive environments, and the anti rust coating should be checked regularly.
Common fault four: fatigue attenuation, manifested as a decrease in spring stiffness and reduced deformation ability, often caused by long-term repeated stress and insufficient material fatigue resistance. Solution: Replace with a more fatigue resistant alloy spring; Optimize working conditions and reduce the impact of repeated loads; Regularly inspect and replace severely attenuated springs in a timely manner.
Daily maintenance skills: Regularly clean the dust and impurities on the surface of the spring to avoid impurities affecting the force; Regularly perform rust prevention treatment in damp and corrosive environments (apply rust proof oil, check rust proof coatings); Avoid overloading the spring and strictly match the load requirements; Long term shutdown equipment, regularly check the status of springs to avoid aging; Precision springs need to avoid collisions and scratches to ensure accurate parameters.
