EMZ supplies 5300 kW Compressor Drive to a manufacturer of technical gases after breakdown
In May 2014, the breakdown of a compressor drive stopped the production of a new air separation plant in Austria.
EMZ was able to offer an available squirrel-cage motor from stock. We delivered the motor, including all customized modifications, within 14 days to Vienna.
In accordance with our customer?s specifications, the following works were accomplished on the 5300 kW squirrel-cage motor in the EMZ workshop in Recklinghausen:
Conversion of the cooling method from IC 611 to IC 01, including production of 2 new air covers for the cooling air inlet and outlet
Adaptation of the fixing holes to meet the existing foundation
Modification of the 6 kV terminal box’s cable entry
Conversion and adaptation of the piping to a central oil supply connection for the sleeve bearings
Modification of the shaft end with a second feather key
In co-operation with the operator and the manufacturer of the compressor, all data were gathered for the starting-up sequence calculation. Also a detailed calculation of the complete drive train was made to reduce all possible risks before the installation. Finally, EMZ was able to guarantee a successful commissioning.
