    Abstract: Fluid pounding in a pumpjack is minimized by dictating the length of the run cycles of the pumpjack. The pumpjack is first allowed to pump down until a fluid pounding state is reached, at which time it is shut down. The time it takes to reach this state is monitored. Using the length of time it took to reach the fluid pounding state, the pumpjack is set to run a predetermined number of dictated cycles for a length of time which is 70-99% of the time it took to reach the fluid pounding state. During these predetermined number of cycles if the pumpjack again reaches a fluid pounding state the time is reset based on this new information, and the number of predetermined number of dictated cycles left is finished. After the predetermined number of cycles has finished, the process is repeated by allowing the pumpjack to run to a fluid pounding state.

    Abstract: A fluid delivery system for delivering a metered dose of fluid from a supply tank (28) to a downstream chamber or vessel (10), comprises a pump apparatus (20) comprising a pump plunger (32) which is operable to perform a pumping stroke under the control of an electromagnetic actuator (36), including a solenoid (36a), to effect delivery of the fluid and a control unit (24) for supplying an input signal (58) to the solenoid (36a) to initiate a current flow to the solenoid (36a) and thereby initiate movement of the pump plunger (32). An electronic device (54) provides an output signal to indicate that movement of the pump plunger has stopped at the end of the pumping stroke, and a timer determines a time difference between the input signal (58) being supplied to the solenoid (36a) and the output signal being output by the electronic device (54). A processor (26) compares the time difference with a predetermined time difference and determines, as a result of the comparison, whether or not the pump plunger (32) has performed a valid pumping stroke in which an intended volume of fluid is displaced and which may therefore be used in a totalized flow calculation.

    Abstract: The invention concerns a concrete pump, of the type comprising a pair of pumping cylinders alternatively operating under the control of a backflow hydraulic pump - to draw concrete from a hopper and feed it, by way of a rocking valve (S-valve), into the transport and delivery duct - wherein said cylinders are provided with stops to control the advance of the starting movements of the S-valve and wherein the motion of the pistons in the cylinders is reversed in respect of the moment in which said pistons reach the top dead center. According to the invention, said stops are located in the position for the most efficient working with the highest number of pumping cycles per minute, and electronic means are provided to set said advance time, by delaying the starting movement of the S-valve and the reversal of the backflow hydraulic pump according to the actual number of pumping cycles per minute.

    Abstract: A vibrating compressor of the present invention, which comprises a piston driving section for driving a piston by supplying a piston driving force, a displacement detecting section connected in an axial direction of the piston, an upper dead point position detecting section for detecting an upper dead point position based on a piston position signal from the displacement detecting section, and a driving force control section for changing the driving force supplied to the piston by the piston driving section according to a difference between the upper dead point position and a preset upper dead point position reference value immediately after the upper dead point position detecting section detects the upper dead point position, prevents its compression efficiency from decreasing due to stabilization and prevents a device from being damaged. In the vibrating compressor, it is also possible to calculate a stroke based on a detected piston position or to control the driving force based on a detected frequency.
