The Disquisition Of Screen Vibration Feeder Failure Analysis And Improve Measures

Screen Machine Vibration Feeders is important transmission equipments of production line in Granulation Workshop Of Complex Fertilizer Plant, imported a total of two from CHAUVIN of France。Installation after only two months,two vibration feeders'steel girders which connected to the electrical excitations have been repeatedly broken。Vibration Feeder support the foundation and steel frame near the floor vibration has been great, a column of floor has a crack, rack and floor intense vibration also has tremendous potential hazards likely to be based on a steel frame vibration collapse, the plant's concrete structure and the cement floor beams may fracture。In this paper, detailed analysis of vibration feeder of the structure and working principle, identify damaged steel girder, set up mechanical model and mathematical model and theoretical investigation, and take effective measures to reduce the failure rate of equipments,rack and plants reduced the vibration and improve the useful life of equipments, ensure normal production and plant security, enhance production efficiency。Check analysis, we believe steel girders because vibrations caused by changes in the pay of fatigue damage。Based on a steel frame and concrete floor vibration is its own screening machine vibration, the vibration absorber capacity insufficient。The original steel structure is irrational, and there are serious stress concentration, needs to be redesigned to strengthen beam, structural design of the time to avoid stress concentration;vibration feeder, rack, floor in the time to work in different source, mutual transmission of vibration and mutual influence, aggravated vibration damage。Passing through the shock absorber for isolation, identify source, due to vibration, the different parts of active isolation and passive vibration isolation, reduce vibration transmission, and run well and has not damaged after transformation has been operating。...
