摘要:
A reciprocating pressure intensifier that compresses compression-targeted fluid into 20MPa to 400MPa by reciprocation of a piston plunger 3. In the reciprocating pressure intensifier, lubricating oil for axial sealing is injected by a lubricating-oil injection pump 7 into a gap between the piston plunger 3 and a cylinder liner 4 into which the piston plunger is inserted. In order to axially-seal the lubricating oil in the gap, the backward end of the piston plunger 3 is provided with a sealing member, and forward end of the piston plunger 3 is provided with no sealing member adjacent to the compression room.
