Definitions

  • This invention pertains to a high-pressure, reciprocating pump useful for high pressure water jet applications, and more particularly to a stuffing box of a high-pressure, reciprocating pump.
  • the stuffing box is subjected to high pressures that can subject the surface of the bore of the stuffing box to tensile loads.
  • the fatigue life of materials is generally better when the material is under compression rather than tension.
  • the .stuffing box is made with a cylinder, having a straight bore, and a sleeve configured to fit therein in a compressive state.
  • the straight bore arrangement is required to have clearance at the time of assembly to permit the sleeve to be installed therein. Such clearance can vary with production tolerances, causing a varying degree of compressive stress in the final product.
  • the present invention is directed particularly to a stuffing box for use in a high- pressure reciprocating pump, as shown and described generally in U.S. Patent Nos. 4,878,815 and 6,231 ,323.
  • the invention provides a high-pressure reciprocating pump including a mounting plate having at least one opening therein. A manifold block is removably secured to the mounting plate.
  • the manifold block has at least one cavity each for receiving a valve cartridge therein.
  • a stuffing box is disposed in each opening of the mounting plate.
  • the staffing box has a central, longitudinal plunger chamber therein for slidably receiving a reciprocating plunger.
  • the stuffing box has a valve end and a packing end.
  • the valve cartridge is disposed adjacent to the valve end of the stuffing box.
  • the stuffing box is in operative relation with the valve cartridge.
  • a packing assembly is disposed adjacent the packing end of the stuffing box. The packing assembly surrounds the plunger in sealing relation to the plunger and to the stuffing box.
  • the stuffing box includes a body and a sleeve.
  • the body has a longitudinal socket with an inner surface tapered over at least a predetermined portion thereof.
  • the sleeve is disposed in the socket of the body.
  • the sleeve has a bore longitudinally disposed therein, which opens to the valve cartridge.
  • the sleeve has an outer surface tapered such that the taper of the outer surface of the sleeve substantially corresponds to the taper of the inner surface of the body.
  • the body compressively retains the sleeve.
  • the sleeve is disposed within the body in a "shrink-fit" for the purpose of pre-loading the bore of the sleeve in compression.
  • the compressive stress which the sleeve is under can act to offset the forces generated by the fluid under pressure in the pressure chamber to increase the life of the stuffing box.
  • To assemble the stuffing box the body is heated at a predetermined temperature.
  • the inner sleeve is placed in the socket of the body to form an assembly. The body is allowed to cool. Once cooled, the body subjects the inner sleeve to a compressive state which is believed to be dependent upon the amount the size of the socket of the body increased during heating.
  • the compressive stress placed upon the sleeve can be accurately controlled. Varying the temperature at which the body is heated at the time of assembly can vary the compressive stress placed upon the sleeve. The more the body is heated the greater the increase in the size of the socket. To increase the compressive stress upon the sleeve, the body can be heated to a higher temperature during assembly.
  • the tapered design reduces cost by facilitating assembly with minimal or no scrap and by achieving the desired results without fabricating the parts with extreme tolerances.
  • the stuffing box is readily assembled. The tapered interface between the sleeve and the body allows the operator to drop the sleeve into the body without the sleeve being retained in the body in a partially inserted manner.
  • the tapered design allows the sleeve and the body to fit with zero clearance at the time of assembly of the stuffing box.
  • the metal-to-metal fit between the sleeve and the cylinder of the stuffing box results in a uniform compressive loading between the parts.
  • the reduction in assembly problems can correspondingly reduce the amount of scrap generated from such manufacturing process and improve part yield.
  • the components need not be reworked dimensionally to change the compressive stress placed upon the sleeve, as in the case of a straight bore cylinder and sleeve arrangement.
  • the assembly method of the staffing box can readily promote uniformity between different stuffing boxes in that each staffing box can be heated to the same temperature during assembly to yield a stuffing box having a sleeve with a compressive stress placed upon it that is substantially the same as the sleeves of the other staffing boxes heated to the same temperature.
