    摘要: A pumping unit, particularly for water supply in remote areas of the world, comprising a pump, control valve and tipping bucket mechanism enclosed in a single housing. The pumping unit is double-acting and, does not demand the presence of a drive pipe. The pump and the automatic control valve are powered by the potential energy of the supply and an independent power source is not necessary or required. The frequency at which the unit operates may be varied by adjustment of the supply of water to the tipping bucket.

    摘要: A system is provided for closed-loop control of a plurality of metering pumps driven by a single source of pressurized fluid. Feedback signals are generated that are proportional to output flow rate from each metering pump, such as velocity of a movable element of the pump with respect to a stationary element. Flow control valves are coupled between the source of pressurized fluid and the metering pumps. A controller receives the feedback signals and regulates flow from the flow control valves to each metering pump to maintain a desired level of output flow. The source of pressurized fluid may include a pressure compensated positive displacement pump having a maximum output flow rate at least equal to the anticipated combined flow rate of drive sections of the metering pumps.

    摘要: A system for metering a fluid, such as a catalyst in an industrial chemical process plant, includes a controller, a drive pump assembly and an injection pump assembly. The drive pump assembly forces reciprocation of the injection pump assembly via a controlled flow of hydraulic fluid. The injection pump assembly includes a drive cylinder and at least one injection section. The drive cylinder receives pressurized fluid from the drive pump assembly and causes metered fluid to be drawn into and expelled by the injection section. The position of reciprocating components of the injection pump assembly is detected between stroke limits and converted to a velocity signal. Closed-loop control of the flow from the injection pump assembly is implemented by the controller via the drive pump assembly based upon the actual velocity of the reciprocating components of the injection pump assembly and a commanded velocity. The closed-loop injection rate control may be incorporated in a nested fashion with a process parameter control loop to maintain a desired level of a process parameter, such as temperature in a reaction vessel.

    摘要: A waterpower machine has a vertical cylinder, the lower end of which is open, a piston which is vertically reciprocable in the cylinder, a water chamber provided at the lower end of the cylinder wherein the water chamber has a water inlet and a water outlet, an inlet valve for controlling water inflow into in the water chamber through the water inlet, and an outlet valve for controlling water outflow from the water chamber through the water outlet. Both the water inlet and the water outlet are opened towards the periphery of the water chamber over the major portion of the water chamber circumference. The water inlet is at a different level from that of the water outlet. The inlet valve and the outlet valve comprise respective ones of a pair of annular valve members which are concentric with one another and with the cylinder and axially moveable between a closed position and an open position.
