Description

Technical Field

[0001] The utility model relates to the technical field of special equipment for sealing dynamic equipment, in particular to a sealing ring pressing tool. Background Art

[0002] Seals are an essential part of dynamic equipment. The main item of dynamic equipment maintenance is to replace seals. Containerized seals are relatively expensive. At present, in order to save costs and avoid waste, most companies purchase non-containerized mechanical seals.

The current method of installing the sealing ring is generally to knock it with a rubber hammer or press it with a press. Hitting with a rubber hammer takes a long time and may not be installed properly or may damage the sealing ring. Installing with a press is bulky and inconvenient to operate, and small-sized seals are easily damaged. Utility Model Content
