    Abstract: A metering pump includes a motor having a motor shaft extending through a drive housing, a carriage assembly disposed around the motor shaft and within the drive housing, a plunger return block mounted to the carriage assembly, a piston disposed along an axis, a carriage bearing disposed on the motor shaft and within the carriage assembly and slidably coupled to the carriage assembly, a cam coupled to the motor shaft to rotate with the motor shaft, and a bearing disposed around the cam to rotate therewith and to contact the stroke adjuster and the plunger return block. The piston also includes a stroke adjuster mounted to the carriage assembly, a plunger having a button-shaped protrusion end, and a drive shaft having a first end connected to the stroke adjuster and a second end having a hook protrusion configured to receive and engage the plunger button-shaped protrusion end.

    Abstract translation: 计量泵包括具有延伸穿过驱动器壳体的马达轴的马达，设置在马达轴周围和驱动壳体内的托架组件，安装到托架组件的柱塞返回块，沿轴线设置的活塞，滑架轴承 设置在电动机轴上并且在滑架组件内并且可滑动地联接到滑架组件，联接到电动机轴以与电动机轴一起旋转的凸轮以及围绕凸轮设置以与其一起旋转并与行程调节器接触的轴承 柱塞返回块。 活塞还包括安装到托架组件的行程调节器，具有按钮形突起端的柱塞和具有连接到行程调节器的第一端的驱动轴，以及具有钩突起的第二端，该钩突起构造成接收和接合 柱塞按钮形突出端。

    Abstract: A fluid handling system suitable for injecting a pressurized fluid from a pump that is driven by a motor into an oilfield network includes a manifold fluidly connected to the pump and a controller. The manifold includes an inlet for receiving the fluid from the pump, a plurality of outlets downstream of and fluidly connected to the inlet, and a plurality of electric valves downstream of and fluidly connected, respectively, to the plurality of outlets, each of the plurality of electric valves being configured to selectively open and close to regulate a flow of the fluid from the plurality of outlets to a plurality of wells fluidly connected, respectively, to the plurality of electric valves. The controller is configured to receive a plurality of flow rate values of the plurality of wells, determine a plurality of duty cycles for the plurality of electric valves based on the plurality of flow rate values, and determine a schedule for the plurality of duty cycles so that only one of the plurality of electric valves is controlled open at a given time.
