Third, the blind replacement of parts and components, the phenomenon of replacement parts repairs exist to varying degrees.
It is relatively difficult to judge and eliminate equipment failures. Some maintenance personnel have always adopted the method of replacement test. Regardless of large and small parts, as long as it is considered that it may be the component that caused the failure, one replacement test. As a result, the fault was not eliminated, and the parts that should not be replaced were replaced at will, and the maintenance cost was increased.
Some faulty parts can be repaired to restore their technical performance, such as generators, air compressors, blowers, burners, gear pumps, etc., and can be repaired without complicated repair processes. During maintenance, the cause and location of the fault should be carefully analyzed and judged according to the fault phenomenon. The repaired parts should be repaired to restore technical performance and eliminate the blind replacement of parts.
