Regeneration of thrust discs

Regeneration of thrust discs

Blurring of the thrust disc of the thrust bearing is a big problem for the owner of the device. However, such cases can be regenerated without dismantling the rotor, which is costly and time-consuming work. To this end, we have developed a device for turning and grinding thrust discs as well another face surfaces on turbine rotors, without disassembly. Local surface hardening, caused by an increase in temperature due to friction – causes of damage – are always a major obstacle that needs to be taken into account in the regeneration of the thrust disc. Usually, the requirements for surface quality and deviation of shape are very high, hence the […]

Regeneration of coupling holes

Regeneration of coupling holes

  It often happens that replacing or upgrading one of the coupled devices, causes the need to regenerate the coupling holes on the “old” side. If the sloping is small, it is sufficient to jointly machine and/or honing pairs of “old” and “new” holes – so-called “pairing”. In the case of large fares, i.e. in cases of: unevenness of the axes of both holes (“spraining”) – usually arose during previous repairs, offsets of the holes’ pitch of the two semi-couplings relative to each other serious damage to the surface of the hole (deep tears, etc.), Ovalization (“’breakdowns’) approaching the limit of “repairability” of the holes due to the need to […]

The repair of bearing foundation in the large elements of port crane Kone in the shipyard, “Crist” in Gdynia

WWTECH SERVICES has completed another repairing project of the foundation in the large-size slewing rings. This time, the task was carried out with the use of the port crane Kone Crist Shipyard Inc. As a result of work, there was obtained the required flatness tolerances of the foundation necessary for the proper operation of the machine. The port cranes are the integral part of the Polish coast landscape. They have become a part of the aesthetics in this part of our country, as well as the history and identity of entire generations of Poles. To ensure an effective work for these devices and enable them the smallest failure in the […]

Leaky pressure valve – the repair of degraded surfaces and the restoration of tightness in the body

Leaky pressure valve – the repair of degraded surfaces and the restoration of tightness in the body

WWTECH SERVICES completed the task to restore the tightness on one of the pressure valves in the steam turbine group of conventional power plant. The machining and repairing work have been carried out without the need for cutting and transporting the element to the workshop, which have allowed for a quick restoration of normal housing tightness and restart the operation of the whole plant. Our technology is the support for keeping the operation of industrial plants that need immediate action.
