Document Type and Number:
WIPO Patent Application WO/2023/241412
Kind Code:
A2
Abstract:
The invention relates to a polishing apparatus, a polishing method and a sealing system. The sealing and polishing apparatus comprises a thrust system; a plurality of sealing systems, wherein each sealing system comprises a piston and a cylinder body matched with the piston; a plurality of conveying pipeline systems, wherein each conveying pipeline system conveys a polishing medium contained in the corresponding sealing system to different ports of an inner flow channel workpiece being polished, and the plurality of sealing systems are communicated by means of the inner flow channel workpiece. The thrust system of the polishing apparatus comprises vertical plunger pumps. The vertical plunger pumps are connected to the pistons to provide a driving force, so that the pistons can move relative to the cylinder body in the vertical direction. The multi-stage pipeline comprises a first-stage pipeline, and a second-stage pipeline adjacent to the downstream of the first-stage pipeline. The first-stage pipeline comprises a curved structure connected to an outlet end of the cylinder body, and the curved structure is connected to the horizontally-extending second-stage pipeline.
