    Abstract: The invention relates to a method for operating a dosing pump, the pump being driven by an asynchronous motor, comprising a drive which converts the motor revolutions into pump strokes of a defined stroke frequency. The pump strokes are comprised of a pump suction stroke and of a pump delivery stroke. Pump strokes are continuously carried out during a dosing phase. The aim of the invention is to provide a solution concerning a dosing pump having an asynchronous motor drive, a frequency converter thereto, and a control unit which interacts therewith in which the dosing behavior is improved during the operation of dosing pumps having an asynchronous motor drive. The invention provides that, with each pump stroke, an electric alternating voltage having a first frequency is applied to the asynchronous motor during the pump suction stroke, and that the same electric alternating voltage having a second frequency which is lower than that during the pump suction stroke is applied to said motor during the pump delivery stroke.

    Abstract: A hybrid electric hydraulic drive system, having a first cylinder (75) having a left chamber (32) and a right chamber (34) separated by a piston (22). A second cylinder (76) has a single or sole chamber (74) for receiving hydraulic fluid with the second cylinder enclosing a second piston (78). The second cylinder is substantially equal in length to the first cylinder and is rigidly attached to the first cylinder. A pump (14) is fluidly connected to the left chamber (32) by a first fluid passage (16) and is fluidly connected to the right chamber (34) by a second fluid passage (18). A third fluid passage (80) is directly connected to the right chamber (34) and to the sole fluid chamber (74) of the second cylinder (76). A first rod (30) is connected to the piston (22) and a second rod (84) is connected to the second piston (78). The first and second rods are connected by a connecting element so the rods move in unison. The volume of the sole chamber (74) is equal to the volume of the first rod (30) with the total fluid capacity of the system remaining constant during operation. An encoder (36) is electrically connected to a controller (40) which is electrically connected to a servo electric motor (10) which drives the pump (14).

    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.

    Abstract: The present invention discloses a system for pumping a fluid into a common pressure outlet. The system contains a plurality of reciprocating pumps. A separate sensor coupled to one cylinder of each pump provides an electrical signal each time the piston in that cylinder is at a predetermined position. A speed control circuit is provided to independently adjust the speed of each pump. Manual speed control for each pump is provided through a separate throttle for each pump. A pump control circuit coupled to each of the throttles, sensors and speed control circuit controls the operation of the system. An operator determines which of the pumps to operate by closing appropriate bypass switches provided at the pump control circuit, turns on the first (master) pump and adjusts its associated throttle to operate the pump at a desired speed. The operator then turns on each of the remaining (slave) pumps. The pump control circuit utilizing the information from each of the sensors provides control signals to the speed control circuit, which adjusts the speed of each of the slave pumps to synchronize the speeds of pumps and to maintain a desired phase shift between the sensor signals. The system also displays the speed of each of the operating pumps and the total fluid volume being discharged by all of the operating pumps.
