Abstract: A seal assembly seals a gap between a pump plunger and a high pressure cylinder of a pump. The assembly includes a seal ring having a bore through which the plunger can extend, a front axial end, and a rear axial end. An O-ring is positioned on the seal ring. A packing ring has a bore through which the plunger can extend, a front axial end abutting the rear axial end of the seal ring, and a rear axial end. A non-metal packing follower has a bore through which the plunger can extend, a front axial end abutting the rear axial end of the packing ring, and a rear axial end. The non-metal packing follower can be ceramic (e.g., carbide) or similar hard, wear-resistant materials.

Abstract: An orifice for a high-pressure waterjet cutter includes a first surface defining an inlet plane, a second surface defining an outlet plane, and an inner bore aligned along a flow axis and extending from the first surface to the second surface. The orifice also includes a first layer of polycrystalline diamond extending from the first surface to a plane between the inlet plane and the outlet plane, and a second, separate layer of polycrystalline diamond extending from the plane to the second surface. The first layer and the second layer are coupled to one another to define a single component. The second layer has material properties different than the first layer.

Abstract: A sealing system for a high pressure pump, in which the pump includes a vessel defining a vessel bore and having an end portion, the vessel bore having a first engagement face and defining a central longitudinal axis, and in which the pump further includes a plunger cooperative with the vessel to increase the pressure of a fluid within the bore, includes a seal member at least partially received within the bore and defining a second engagement face. The sealing system further includes a retaining member in operative contact with the seal member to mate the first engagement face with the second engagement face to inhibit fluid leakage from the bore. The first engagement face includes a first contacting surface having a non-linear cross-section. The second engagement face includes a second contacting surface having a non-linear cross-section in contact with the first contacting surface.

Abstract: One or more components of a high pressure pump include a hydraulic surge dampener. The hydraulic surge dampener mitigates or prevents damage that results from a sudden pressure surge that results from impact of components, for example a hydraulic piston and a hydraulic head, of the high pressure pump. The hydraulic surge dampener may include one or more grooves, one or more through holes, or a combination thereof. The hydraulic surge dampener may be carried by or be part of one or more components of the high pressure pump, such as the hydraulic piston, the hydraulic head, or both.

Abstract: A sealing system for a high pressure pump operable above 15,000 psi includes a first engagement face formed as part of the vessel and defining an opening into the vessel bore, the first engagement face having a concave cross-section. A seal member is at least partially received within the bore and defines a second engagement face, the second engagement face having a convex cross-section. A retaining member is coupled to the seal member and is operable to move the seal member from an initial contact position with the vessel to a sealing contact position, wherein the first engagement face and the second engagement face define a first contact angle with respect to the axis in the initial contact position and a second contact angle that is greater than the first contact angle in the sealing position.
Abstract translation: 用于高于15,000psi的高压泵的密封系统包括形成为容器的一部分的第一接合面，并且在容器孔中形成开口，第一接合面具有凹形横截面。 密封构件至少部分地容纳在孔内并且限定第二接合面，第二接合面具有凸形横截面。 保持构件联接到密封构件并且可操作以将密封构件从与容器的初始接触位置移动到密封接触位置，其中第一接合面和第二接合面相对于第一接合面限定第一接触角 并且第二接触角大于密封位置中的第一接触角。
