Abstract
A fluid sealing system for a rotary mechanical device including a pillar lantern ring having a bottom and a top end cap with pillars or columns connecting the end caps is formed by additive manufacturing. The bottom annular end cap has an outside face and an opposed inside face defining a height therebetween and the upper annular end cap has an inside face and an opposed outside face defining a height therebetween with a plurality of integrally formed substantially cylindrical axial columns connecting the two opposed inside faces of the two end caps.
Claims14
A method for forming a lantern ring for use in an annular seal cavity of a rotary mechanical device having an output end and a power end with a shaft running through the seal cavity, comprising:
- using additive manufacturing to form a substantially rigid unitary cylindrical body having an outside surface dimensioned to fit into the annular seal cavity and an inside dimension to fit about the shaft of the rotary mechanical device with a bottom annular end cap having an outside face and an opposed inside face defining a height therebetween and an upper annular end cap having an inside face and an opposed outside face defining a height therebetween;
- and
- using additive manufacturing to integrally connect the two opposed inside faces of the two end caps to form a flush volume.
