Description

Portable packing casing processing apparatus and its processing method {Portable packing casing processing machine and processing method using the same}

One embodiment of the present invention relates to a portable packing casing processing apparatus and a processing method thereof.

In a power generation facility, during long-term operation of a steam turbine, the high-temperature and high-pressure steam generated in the boiler passes through the tube, and the oxidized iron oxide (Fe3O4) in the tube flows into the turbine along with the high-temperature and high-pressure steam. It also causes various damage to and fixtures, and in the process of starting/stopping turbines, equipment used in wet steam or low-temperature and low-pressure steam conditions may also be damaged by erosion and corrosion.

The gland packing casing of the turbine operates in a low-temperature and low-pressure region, and during long-term operation, erosion and corrosion of the sealing face are easy to occur due to wet steam with low dryness.

Gland Packing consists of a sealing and venting pressure chamber to close the structural gap between the fixed body and the rotating body of the turbine to maintain the vacuum level of the turbine and to leak steam to the outside of the turbine. However, there was a problem that the sealing face of the assembly groove in which the packing ring is assembled is damaged due to erosion and corrosion during operation for a long time.

Turbine operation may become impossible due to such a problem, and equipment to restore it is required, but there is a problem in that substantially all of these gland packing casings are taken out and processing cannot be performed. In particular, even in the case of the equipment of the power plant, there was a problem that it was impossible to work by taking some casings out.

Therefore, in this case, there is a need for a processing apparatus for a packing casing that can effectively improve processing precision in a narrow space and can be carried.
