    摘要： A double acting hydraulic pressure intensifier (1) is described comprising a housing (2), a first piston arrangement (7) having a first high pressure piston (8) in a first high pressure chamber (3) in the housing (2) and a first low pressure piston (9) in a first low pressure chamber (5) of the housing (2), a second piston arrangement (10), having a second high pressure piston (11) in a second high pressure chamber (4) in the housing (2) and a second low pressure piston (12) in a second low pressure chamber (6) in the housing (2), and a switching valve (14) having a valve element (15). Such a pressure intensifier should be made compact. To this end the switching valve (14) is located between the first piston arrangement (7) and the second piston arrangement (10).

    摘要： A method for synchronizing pistons within linear pumps of a variable dispense ratio system comprises operating first and second pistons, controlling the first and second pistons, and reversing direction of one of the first and second pistons. The first and second pistons are operated within first and second cylinders so that the first piston moves at a slower speed than the second piston to produce a variable dispense ratio. The first and second pistons are controlled to reverse directions whenever one piston reaches an end of its respective cylinder to produce pumping. One of the first and second pistons reverses direction before either piston reaches an end of its respective cylinder to adjust the synchronicity of the pistons.

    摘要： Systems and methods for operating a linear pump system involve operating a linear motor system; reciprocating a linear pump and a motor control module that issues commands and a control logic input to the linear motor system. The linear motor system is operated to reciprocate an output shaft between first and second reversal positions. The linear pump is reciprocated with the output shaft to produce a flow of material. A pump reversal command reverses direction of the output shaft. A torque command controls speed of the output shaft. The control logic input reciprocates the output shaft at speeds to produce a constant output condition of the flow of material. The motor control module adjusts the torque command to operate the output shaft at an increased speed above what is necessary for the constant output condition for a temporary time period beginning when the reversal command is issued.

    摘要： A method for operating a reciprocating positive displacement pump for the simultaneous low-pulsation discharge of a plurality of liquids, having for each liquid at least two pump chambers and displacement devices capable of movement therein, of which the one displacement device takes in liquid during the actual discharge phase of the other displacement device, and at the end of its intake stroke reverses its direction of movement, and, in a pre-compression phase, pre-compresses the liquid taken into the associated pump chamber and when a predeterminable pre-compression pressure has been achieved comes to a standstill, and remains at the standstill until the other displacement device has ended its liquid discharge, and, subsequent to this discharge, begins its own discharge. The method includes the steps of carrying out a pressure compensation during the subsequent discharge stroke preventing a pressure compensation between the individual pump chambers during the subsequent discharge stroke.
