Comparison of the status before and after carried out modernization
Target
The target was the complete moderni-zation of a stock plant for the production of sealing covers of the drive shaft manufacturing. The plant arose in the eighties. The lifetime of all components was exceed-ed and it becomes necessary to update the plant to the best available technology.
Mechanical modernization
The equipment was deconstructed in all single parts and all wear parts of the plant (journals, connectors, sealing gaskets, gear rings and guiding shafts) were replaced. The existing plant lubrication was changed to a semi-fluid lubrication with distributors. By using new cylinders and corresponding valve controls the pneumatic system was modernized all around. A higher plant dynamic was achieved by using servo drives.
Electrical modernization
It becomes necessary to replace the electrical plant installation including switchboard cabinet and servicing level completely. All safety functions were realized by the use of safety control and corresponding drive controllers. Via transponder technology the manipulation of movable guards was prevented. An image processing system was applied for the quality control of different product types.
Process optimization and visualization
Via visualization tailored to the plant an operator guided control as well as an optimal process supervision of all plant conditions were realized.
CE and dokumentation
Based on the new conformity declaration of the plant it becomes necessary to prepare an extensive documentation including risk evaluation according to appendix VII of the EC machinery directive.
