Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a multifunctional test run repair platform. Background Art

[0002] In the prior art, the wear of fan rotors is solved by using an offline repair method, in which the fan rotor is disassembled as a whole and sent to a repair factory for repair. Due to the special structure of the rotor impeller, a dynamic balancing test must be carried out after the repair is completed. This requires multiple people to operate and the detection data is complex, which can easily lead to extended construction time and uncontrollable quality. Under special circumstances, it cannot stay in the repair factory for a long time, and it cannot even leave the production plant for repair by the repair factory. Repairs need to be carried out within the company. Since there is no fan rotor repair and test platform in the company, the fan rotor cannot be tested after repair, and it cannot be used on the machine without a test run, so a tooling platform that can be repaired and tested must be designed.
