Abstract
A spiral wound header ring is provided. The spiral wound header ring comprises at least one outer fabric layer and at least one spiral of inner fabric and rubber. The spiral wound header ring further may have a sealing surface that extends from a rearward facing surface to the forward facing annular, radially extending, surface.
Claims19
A header ring, comprising:
- a forward facing portion with an annular forward facing radially extending surface with an inner diameter edge;
- an annular, radially and axially extending, convex sealing surface extends from a rearward facing surface to the inner diameter edge of the forward facing portion forming an obtuse angle between the forward facing portion and the annular, radially and axially extending, convex sealing surface;
- at least one outer layer of fabric;
- and
- a spiral wound core contained by the at least one outer layer of fabric,
- the spiral wound core alternatingly comprising:
- a plurality of inner layers of fabric, and
- a rubber layer interspersed between the plurality of inner layers of fabric.

A packing system for a compressor pump including at least one pressure ring and at least one header ring, the header ring for the compressor pump comprising:
- a plurality of outer fabric layers;
- a header ring core enveloped by the plurality of outer fabric layers, wherein the plurality of outer fabric layers and the header ring core form a shape for the header ring comprising:
- an annular, radially extending forward facing surface having an inner diameter edge and an outer diameter edge;
- an annular, axially extending surface having a forward facing edge and a rearward facing edge where the forward facing edge abuts the outer diameter edge of the annular, radially extending forward facing surface;
- at least one annular and radially extending rearward pressure ring surface having an outer diameter edge and an inner diameter edge where the outer diameter edge abuts the rearward facing edge of the annular, axially extending surface;
- and
- at least one sealing surface radially and axially extending having a rearward facing edge and a forward facing edge wherein the rearward facing edge abuts the inner diameter edge of the at least one annular and radially extending rearward pressure ring surface and the forward facing edge abuts the inner diameter edge of the annular, radially extending forward facing surface forming an obtuse angle between the forward facing surface and the sealing surface;
- and
- wherein the header ring core comprises at least one fabric layer and at least one polymer layer.
6 more elements
A header ring, comprising:
- at least one outer layer of fabric;
- and
- a spiral wound core contained by the at least one outer layer of fabric,
- the spiral wound core alternatingly comprising:
- a plurality of inner layers of fabric, and
- a rubber layer interspersed between the plurality of inner layers of fabric, wherein the plurality of inner layers of fabric are contiguous and originate at about a center of the header ring and spiral outwards and wherein the at least one outer layer of fabric is contiguous with the plurality of inner layers of fabric.
