Maintenance and repairs






The serviceability of the worn parts of machines and equipment (owing to abrasive, erosive, cavitation or corrosion wear) may be restored by their renovation.
Maintenance may be applied to partially or totally damaged parts of machines and equipment owing to breakdowns, cracks or fractures formed as consequence of material fatigue and/or overloading of parts in the service, inner defects in material, unsuitable design solution, application in unsuitable service conditions, insufficient maintenance etc. fabricated of different materials as for example: steel, cast iron, aluminium and its alloys, non-ferrous metals, titanium and its alloys and others.
We have a long-time experience with renovations and repairs of parts of machines and equipment, experienced personnel, proved working procedures, technical and material outfit.


Advantages of maintenance:

 

  • the renewed parts may be of any shape, dimensions or weight (from several grams to tens of tons),
  • the renewed part can be made of different materials (plain, low-alloy, high-alloy steels, tool steels, steels for castings, cast irons, aluminium and its alloys, copper and its alloys titanium and its alloys etc.),
  • the parts may be renovated and repaired directly in the working facility without disassembly and/or after dismantling also in our renovation shop, 
  • we can ensure the repairs of parts also in the field (without possibility of mains connection) whereas the costs for renovation are always lower than the costs for fabrication of new parts.

 

Maintenance and repairs are suitable mainly for the machines and equipment where: 

  • it is impossible to provide the spare parts on the market (unique or elderly equipment),
  • it is necessary to prolong the life of machines, equipment and investment units,
  • it is necessary to enhance the utility properties of parts (the renovated surfaces exert usually better properties than the original ones, for example the wear resistance, hardness, corrosion resistance eventually finer appearance),
  • it is necessary to reduce the operational costs, service costs, new investments etc.
  

 

Examples of maintenance of worn parts:

  • rollers of cranes and cement furnaces, teethed wheels, shafts, crusher hammers, wheel of railroad vehicles, rails, mixers, tools, dies etc..
  • repairs of damaged parts: frames and stands of presses, rams, chip machining machines, crushers, moulds for casting metals and plastics, shafts, gearboxes, bodies of pumps, compressors and car engines, car bodies, blades of turbines and industrial fans, bells (including the reconstruction of their relief and clapper), agricultural , constructional and road machines, pipelines, welded structures, pylons of electric lines etc.
