    • 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.
    • 一种用于诊断高压泵中的部件的方法和装置,以指示泵头的部件何时发生故障并识别故障部件。 在一个实施例中,结合根据本发明的诊断系统的高压泵头具有至少部分地容纳在加压室中的加压室和加压构件。 加压构件沿着进气动作在加压室内移动,以将流体引入加压室,并沿加压动作压缩加压室中的流体。 入口流体控制组件联接到加压室以允许流体在进气动作期间进入加压室,并且加压流体控制组件联接在加压室和出口室之间,以选择性地允许加压流体进入出口室 加压动作。 泵头还可以包括诊断系统,用于指示进口流体控制组件,加压流体控制组件和泵头的其他部件在入口流体控制组件上游相对于流过流体流体的流体流动的操作状态 泵头在加压动作期间。

    • A pressure cycling system includes a reaction chamber configured to receive a sample and a charge pump in fluid communication with the reaction chamber. The charge pump is operable to convey a fluid from a fluid source toward the reaction chamber. The system also includes a check valve disposed between the charge pump and the reaction chamber. The check valve is operable to inhibit the flow of fluid from the reaction chamber toward the charge pump. A pressure intensifier is in fluid communication with the reaction chamber. The pressure intensifier is pneumatically operable to adjust a pressure in the reaction chamber. A controller is configured to control operation of the charge pump and the pressure intensifier. The controller is configured to pressurize the reaction chamber to a first pressure through operation of the charge pump. The controller is also configured to fluctuate the pressure in the reaction chamber between a second pressure and a third pressure through operation of the pressure intensifier.
