Description

Technical Field

[0001] The utility model relates to the technical field of sealing packing processing, in particular to a sealing packing cutting device for a water turbine generator set. Background Art

[0002] Sealing packing plays an important role in preventing high-pressure fluid from leaking out of the pump and preventing air from entering the pump in the hydro-turbine generator set. The sealing packing cutting device of the hydro-turbine generator set is specially used to cut the sealing packing of the hydro-turbine generator set to ensure that the size and shape of the sealing packing meet the requirements of the unit, which is crucial to maintaining the normal operation of the hydro-turbine generator set and ensuring the sealing performance of the unit.

[0003] In the existing technology, the sealing packing cutting device of a hydro-turbine generator set is mainly composed of a conveying mechanism, a cutting mechanism, etc., and usually uses a motor to drive a roller to move the sealing packing to be processed to a cutting position, and then a sharp cutting blade accurately cuts the sealing packing according to preset cutting parameters. However, in actual use, when the cutting blade cuts the sealing packing, the sealing packing to be processed is moved to a specified position by a roller. Since the appropriate conveying width cannot be adjusted according to the size of the sealing packing, the sealing packing is easily bent during the movement, resulting in different lengths of cut each time, thereby affecting the processing effect of the sealing packing. In addition, when the device is conveyed by a roller, and since the roller is fixed, the device cannot adapt to the conveying of sealing packings of different thicknesses, therefore, it is necessary to improve a sealing packing cutting device for a hydro-turbine generator set.
