摘要： To regulate the flow rate of an electric motor-driven hydraulic pump (6, 6', 18) that is activated by a variable pulse/pulse-break train (UA) and that serves to supply auxiliary pressure to a brake system with ABS and BASR, the generator voltage (UGen) produced by the pump motor (7, M) during times of pulse break (Taus) is evaluated as a measure of pump speed. In a control circuit the set value (USOLL) for pump speed is compared with the actual value (UIST) of the pump speed and the new correcting variable for activating the pump is derived from the difference.

摘要： The invention relates to a control device for a membrane pump for feeding a filter press or similar consumers. The inventive device comprises an electric three-phase motor for driving the pump. Said motor is linked with the supply system via a frequency-adjustable frequency converter, said frequency converter having an analogous output at which an actual signal corresponding to the respective motor torque is output. The device further comprises a transmitter for the desired engine speed to whose input the desired signal is transmitted via an inverter. In said transmitter a curve is stored which describes a correlation between the motor torque and the engine speed in such a manner that the curve for the engine speed runs along a constant maximum value at small actual signal values and gradually decreases to a minimum value once a predetermined value for the actual signal is reached. The inventive device also comprises an attenuation step for the actual signal.

摘要： A control system of a hydraulic pump (1) in a load sensing control hydraulic drive circuit, comprising: a first means (202) in which a target pressure difference between the discharge pressure of the hydraulic pump and the load pressure of an actuator (2) is set as a variable value; second means (203, 210-213) for determining a controlling coefficient which increases with an increase in deviation of this target pressure difference as a variable value from an actual pressure difference, decreases with a decrease thereof and increases for a relatively small deviation of the pressure difference when the target pressure difference is small; and third means (205, 206) for determining the target displacement volume from the deviation of the pressure difference and the controlling coefficient; whereby, irrespective of a value of the target pressure difference, stabilized control of the hydraulic pump can be performed, without causing hunting when the operating speed of a control lever (3a) is low, and, when the operating speed of the control lever is high, the control of the hydraulic pump with prompt and quick responses can be performed.

摘要： An enteral feeding pump motor unit (10) and method of use are disclosed. The motor unit (10) uses optical sensors (54) to monitor the rotational period and position of a platen (22) of the motor unit (10). If the rotational period is different from a predetermined desired period, a controller in communication with the optical sensors (54) and the platen (22) changes the rate at which the platen rotates so as to effectuate movement of a desired amount of fluid through a delivery set passing through the motor unit (10). In accordance with one aspect of the invention, the optical sensors (54) are disposed in an asymmetrical pattern to enable self-testing and to avoid ambiguous readings.
