Description

Technical Field

[0001] The utility model relates to the technical field of fluid transportation and pressure-boosting equipment, in particular to a lining disassembly and assembly device for a slurry circulation pump. Background Art

[0002] During the replacement of the mechanical seals on the slurry circulating pumps at the Heshan Thermal Power Plant, the pumps needed to be disassembled to replace the seals. Because the pumps consist of two half-covers and a lining, removing the inlet half-cover exposed the entire circulating pump lining. This lining needed to be lifted out before further disassembly could proceed. However, the circulating pump lining was heavy, and there was no direct access to wire ropes, lifting rings, or other lifting equipment, making it impossible to lift or install the circulating pump lining. To address this issue, after careful research, a circulating pump lining lifting and disassembly device (see attached figure for details) was developed, taking into account the structure of the circulating pump lining. This device solves the problem of lifting or installing the circulating pump lining. Utility Model Content
