  • Publication number: 20120141305
    Abstract: A stay rod connects a power end to a fluid end of a high pressure well service pump where the pump has a pump motor face on a power end which is spaced apart from a joining face of a fluid end by the stay rods. The stay rods each have an elongated unitary body having first threaded end which is sized to be received in a mating threaded opening provided in the motor face of the power end of the pump and a second opposing threaded end which is sized to be received in a mating opening provided on the joining face of the fluid end of the pump. The intermediate portion is of a greater relative diameter than either of its first and second threaded ends and is provided with a series of elongated flats which begin at the approximate juncture between a shoulder joining the second threaded end and extending in the direction of a shoulder joining the first threaded end. Each flat forms a torque surface for engagement by a torque wrench for torquing and installing the stay rod.

  • Publication number: 20080290548
    Abstract: An improved pellet mill is shown which has an annular die of the kind having a multiplicity of radial bores through which raw material is extruded to form pellets. The annular body of the die has an inner circumferential surface which defines a compression side of the die, and an outer circumferential surface which defines a discharge side of the die. The compression side and discharge side of the body are separated by a thickness therebetween with the radial bores extending through the thickness from the compression side to the discharge side thereof. Each die hole begins as a countersink region on the compression side of the die body. The countersink region leads to a compression hole which communicates with the discharge side of the die body. Each of the compression holes has an internal diameter and a length. The ratio of the internal diameter to length of each compression hole is at least about 16:1.
