Abstract

A starter ring for a pump packing assembly is disclosed. The assembly comprises an annular portion adjacent to an opening of a housing cylindrical surface. An axially outwardly extending portion opposite the opening and engaged with the housing cylindrical surface. Layers of a fabric reinforced elastomeric material covering the radially inwardly extending annular portion and the axially outwardly extending portion. A male adapter pocket is positioned at one side of the starter ring and configured to displace the volume of the starter ring and to generate a wiper force for initiating a wiping effect on the adjacent position of the at least one resembling shape of annular sealing ring. The male adapter pocket allows pressure forces from the reciprocating plunger to intensify the wiping effect of the starter ring, and exclude proppants from coming in contact with the at least one resembling shape of annular sealing.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A starter ring for a pump packing assembly, the assembly comprising:
 a plunger reciprocally positioned within a cylindrical bore that is extending and forming a radially inwardly facing housing cylindrical surface, and an annulus is formed between the housing cylindrical surface and the plunger;   at least one resembling shape of annular sealing ring positioned in the annulus; and   a starter ring positioned in the annulus and engaged with the at least one resembling shape of annular sealing ring,   wherein the starter ring defines an opening through which the plunger extends, and   wherein the starter ring has a resilient body comprising:
 a radially inwardly extending annular portion adjacent the opening and engaged with the housing cylindrical surface; 
 an axially outwardly extending portion opposite the opening and engaged with the housing cylindrical surface; and 
 a layer of a fabric reinforced elastomeric material covering the radially inwardly extending annular portion and the axially outwardly extending portion; 
   a male adapter pocket positioned at one side of the starter ring and configured to displace the volume of the starter ring and to generate a wiper force for initiating a wiping effect on the adjacent position of the at least one resembling shape of annular sealing ring,   wherein the male adapter pocket allows pressure forces from the reciprocating plunger to intensify the wiping effect of the starter ring, and exclude proppants from coming in contact with the at least one resembling shape of annular sealing ring.   
     
     
         2 . The assembly of  claim 1 , wherein the fabric reinforced elastomeric material is selected from a group consisting of natural rubber and synthetic rubber. 
     
     
         3 . The assembly of  claim 1 , wherein the at least one resembling shape of annular sealing ring correspond to one or more pressure rings that are interchangeable inside the pump packing assembly. 
     
     
         4 . The assembly of  claim 3 , wherein the one or more pressure rings are maintained in a static location within an inner diameter of the pump packing assembly by the starter ring. 
     
     
         5 . The assembly of  claim 1 , wherein the starter ring and the male adapter are dimensionally combined with proper height are the same height as a standard header ring. 
     
     
         6 . The assembly of  claim 1 , wherein the elastomeric material core of the starter ring provides a 360-degree spring resilience that maintains a radially outward force for the wiping pressure to prevent abrasives from annular sealing rings from dithering inside the pump packing assembly. 
     
     
         7 . A starter ring for a reciprocating plunger-type pump, the pump adapted to displace a fluid, comprising:
 a plunger reciprocally positioned with a cylindrical bore that is extending and forming a radially inwardly facing housing cylindrical surface, and an annulus is formed between the housing cylindrical surface and the plunger;   at least one resembling shape of annular sealing ring positioned in the annulus; and   a starter ring positioned in the annulus and engaged with the at least one resembling shape of annular sealing ring,   the annular sealing ring having a high pressure end and circumscribing and slidingly engaged by the plunger and the starter ring;   wherein the starter ring has forward facing surfaces and rearward facing surfaces, the forward facing surfaces being disposed at the high pressure end of the sealing ring and the rearward facing surfaces being engaged with the annular sealing ring,   wherein the starter ring defines an opening through which the plunger extends, and   wherein the starter ring has a resilient body formed of a non-fabric reinforced homogeneous elastomeric material, comprising:
 a radially inwardly extending annular portion adjacent the opening and engaged with the housing cylindrical surface; 
 an axially outwardly extending portion opposite the opening and engaged with the housing cylindrical surface; and 
 a layer of a fabric reinforced elastomeric material covering the radially inwardly extending annular portion and the axially outwardly extending portion; 
   a male adapter pocket positioned at one side of the starter ring and configured to displace the volume of the starter ring and to generate a wiper force for initiating a wiping effect on the adjacent position of the at least one resembling shape of annular sealing ring,   wherein the male adapter pocket allows pressure forces from the reciprocating plunger to intensify the wiping effect of the starter ring, and exclude proppants from coming in contact with the at least one resembling shape of annular sealing ring.   
     
     
         8 . The starter ring for a reciprocating plunger-type pump of  claim 7 , wherein the fabric reinforced elastomeric material provides a constant force to maintain the adjacent pressure rings in a static location or position on inside diameter of the stuffing box bore of the reciprocating plunger-type pump.
