    • A high pressure relief valve for use in a high pressure fluid pump is shown and described. In a preferred embodiment, a valve seat is provided with a tapered hole and with a conduit, the tapered hole and conduit being in fluid communication with each other and with fluid having a variable pressure. A tapered pin having grooves is held in the tapered hole by a control force, or control pressure acting through a plunger. When the pressure of the fluid is sufficiently high to overcome the control force or pressure, the tapered pin is forced to move sufficiently to create an annular clearance between the tapered pin and the tapered hole, thereby allowing pressurized fluid to flow past the pin to an outlet. An outer surface of the valve seat in a region of the tapered pin is tapered in an opposite direction to that of the tapered hole, thereby weakening the valve seat in that region, such that the tapered hole is able to expand and contract as the pressure of the fluid increases and decreases.
    • 示出并描述了用于高压流体泵的高压溢流阀。 在优选实施例中,阀座设置有锥形孔和导管,锥形孔和导管彼此流体连通并且具有可变压力的流体。 具有凹槽的锥形销通过控制力或通过柱塞作用的控制压力保持在锥形孔中。 当流体的压力足够高以克服控制力或压力时,锥形销被强制移动以在锥形销和锥形孔之间产生环形间隙,从而允许加压流体流过销钉到 出口。 在锥形销的区域中的阀座的外表面与锥形孔的方向相反的方向是锥形的,从而削弱该区域中的阀座,使得锥形孔能够作为压力膨胀和收缩 的流体增减。

    • A high pressure fluid seal assembly is shown and described. The seal assembly includes a seal carrier having a bore through which a reciprocating pump plunger may pass, the seal carrier having a first annular groove concentric with the bore, and carrying an annular seal. The seal carrier further includes an integral annular guidance bearing positioned in a second annular groove of the seal carrier, the second annular groove and guidance bearing contained therein being axially spaced from the first annular groove and seal contained therein. An inner diameter of the guidance bearing is smaller than an inner diameter of the seal carrier in a region between the seal and the guidance bearing. The seal is therefore supported directly by the seal carrier, although the seal carrier is spaced from the reciprocating plunger by the guidance bearing. Frictional heating in the region of the seal is therefore reduced, thereby increasing the life of the seal. Materials for the plunger, seal and guidance bearing are selected to minimize friction between the plunger and seal and between the plunger and guidance bearing. Furthermore, the seal assembly is manufactured by pressing the guidance bearing into the seal carrier, and then machining the bore in the guidance bearing and in the seal carrier in the same setup, thereby improving the alignment of the elements and simplifying manufacturing.
    • 示出并描述了高压流体密封组件。 密封组件包括具有孔的密封载体,往复式泵柱塞可穿过孔,密封载体具有与孔同心的第一环形槽,并且承载环形密封件。 密封托架还包括定位在密封载体的第二环形槽中的整体环形引导轴承,其中容纳的第二环形槽和引导轴承与其中容纳的第一环形槽和密封件轴向间隔开。 引导轴承的内径小于密封件和引导轴承之间的区域中的密封件的内径。 因此,密封件由密封载体直接支撑,尽管密封载体通过引导轴承与往复式柱塞间隔开。 因此,密封区域中的摩擦加热减少,从而延长密封件的使用寿命。 选择柱塞,密封和引导轴承的材料,以最小化柱塞和密封件之间以及柱塞和导向轴承之间的摩擦。 此外,通过将引导轴承压入密封载体,然后在同一设置中在引导轴承和密封载体中加工孔,从而改善元件的对准并简化制造,来制造密封组件。

    • A low wear poppet valve in a high pressure reciprocating pump. Relative movement of the mating surfaces due to compressive distortion is eliminated. There is a valve seat having a flow passage and an upper mating surface, and a poppet element which sealingly abuts this. The flow passage is in communication with a low pressure zone, and the outer surfaces of the seat and element are in communication with a high pressure zone. The poppet element has a recess in its mating surface surrounded by a wall portion, and the low pressure zone is communicated from the flow passage into the interior of the recess. This enables the wall portion of the element to be displaced inwardly and outwardly in concert with the wall portion of the seat by the cyclic pressure differential which is generated between the zones by the operation of the pump. This eliminates relative movement between these parts which would otherwise cause fretting wear of their mating surfaces.
    • 高压往复泵中的低磨损提升阀。 消除了由于压缩变形引起的配合表面的相对移动。 有一个阀座具有一个流动通道和一个上配合表面,以及一个密封地邻接这个的提升阀元件。 流路与低压区连通,座与元件的外表面与高压区连通。 提升件在其配合表面上具有由壁部包围的凹部,低压区从流路连通到凹部的内部。 这使得元件的壁部分可以通过由泵的操作在区域之间产生的循环压力差而与座椅的壁部一起向内和向外移位。 这消除了这些部件之间的相对移动,否则这些部件将会引起其配合表面的微动磨损。

    • A coupling for a high pressure fluid seal assembly is shown and described. The coupling includes a first member having first and second opposite ends and capable of motion along a first axis extending between the first and second ends. The first member has an engagement portion positioned toward the first end having a rounded convex engagement surface. The coupling further includes a second member also having first and second opposite ends and capable of motion along a second axis extending between the first and second ends of the second member. A second engagement portion toward the second end of the second member has a substantially flat second engagement surface engaging the first engagement surface of the first member. The interface between the first and second engagement surfaces aligns motion of the first member along the first axis with motion of the second member along the second axis. The coupling accordingly reduces the tendency for either the first or second member to bend. The coupling assembly further reduces the tendency for the first and second members to move laterally relative to their respective longitudinal axis.
    • 示出并描述了用于高压流体密封组件的联接器。 联接器包括具有第一和第二相对端并且能够沿着在第一和第二端之间延伸的第一轴线运动的第一构件。 第一构件具有朝向具有圆形凸形接合表面的第一端定位的接合部。 联接器还包括第二构件,其还具有第一和第二相对端并且能够沿着在第二构件的第一和第二端之间延伸的第二轴线运动。 朝向第二构件的第二端的第二接合部分具有接合第一构件的第一接合表面的基本平坦的第二接合表面。 第一和第二接合表面之间的界面使第一构件沿着第一轴线的运动与第二构件沿着第二轴线的运动对齐。 联接器相应地减小了第一或第二构件弯曲的倾向。 联接组件进一步降低了第一和第二构件相对于它们各自的纵向轴线横向移动的趋势。

    • A self-venting seal assembly for use in an ultrahigh-pressure pump is shown and described. In a preferred embodiment, a low-pressure seal is used to energize a high-pressure seal, the low-pressure seal having a "u" shaped cross-section, thereby creating a groove in a first end of the low-pressure seal. When the first end of the seal is exposed to pressurized fluid, it expands outwardly thereby substantially preventing the leakage of fluid past it. To the extent that any pressurized fluid does leak past the seal, which would act against a second end of the seal when the pressure on the opposite side of the seal drops, the seal compresses inwardly, thereby allowing the pressurized fluid to flow back past the seal.In a preferred embodiment, the high-pressure seal comprises a sleeve seal having an annular opening through which the plunger reciprocates, the sleeve seal being supported by a backup ring, the backup ring also having an annular opening through which the plunger passes. The sleeve seal and backup ring are configured such that they may be placed in an annular bore of a seal carrier and an annular end surface of the sleeve seal and an annular surface of the backup ring abut each other and are substantially flush, thereby simplifying manufacturing and installation of the seal assembly.
    • 示出并描述了用于超高压泵的自排气密封组件。 在优选实施例中,使用低压密封来激励高压密封件,低压密封件具有“u”形横截面,从而在低压密封件的第一端中形成凹槽。 当密封件的第一端暴露于加压流体时,其向外膨胀,从而基本上防止流体经过它的泄漏。 在任何加压流体确实泄漏通过密封件的情况下,当密封件的相对侧上的压力下降时,该密封件将作用于密封件的第二端,密封件向内压缩,从而允许加压流体回流经过密封件 密封。 在优选实施例中,高压密封件包括具有环形开口的套筒密封件,柱塞往复运动,套筒密封件由支撑环支撑,支撑环还具有柱塞通过的环形开口。 套筒密封和支撑环被构造成使得它们可以被放置在密封载体的环形孔和套筒密封件的环形端面中,并且支撑环的环形表面彼此邻接并且基本上齐平,从而简化制造 并安装密封组件。

    • A method and apparatus for diagnosing components in high-pressure pumps to indicate when a component of the pump head is malfunctioning and to identify the malfunctioning component. In one embodiment, a high-pressure pump head incorporating a diagnostic system in accordance with the invention has a pressurization chamber and a pressurizing member at least partially received in the pressurization chamber. The pressurizing member moves within the pressurization chamber along an intake action to draw fluid into the pressurization chamber and along a pressurizing action to compress fluid in the pressurization chamber. An inlet fluid control assembly is coupled to the pressurization chamber to allow fluid to enter the pressurization chamber during the intake action, and a pressurized fluid control assembly is coupled between the pressurization chamber and an outlet chamber to selectively allow pressurized fluid into the outlet chamber during the pressurizing action. The pump head may also include a diagnostic system to indicate the operational status of each of the inlet fluid control assembly, the pressurized fluid control assembly and other components of the pump head upstream from the inlet fluid control assembly with respect to a fluid flow through the pump head during the pressurizing action.

    • A pressure compensation device for use in a high-pressure direct driven pump to control the output pressure of the pump is shown and described. In a preferred embodiment, the high-pressure pump has a valve assembly that selectively allows fluid pressurized by a reciprocating plunger to pass from a pressurization chamber to an outlet chamber from which the pressurized fluid is collected for use. A pressure compensation device has a lever which balances a control force against a force generated by the high-pressure fluid in the outlet chamber. When the outlet pressure exceeds a selected level, the pressure compensation device acts to prevent the further pressurization of fluid by causing the fluid to flow back out of the pressurization chamber via the same passageway(s) through which the fluid was originally introduced into the system.
