Abstract: The load torque of a compressor for circulating refrigerant in a refrigerating cycle changes with the rotational position of the shaft of the compressor, and the phase difference between the primary current and voltage of an induction motor for driving the compressor changes with the load torque. Taking the above facts into consideration, in turning off the compressor driven by the induction motor, which is powered by a fixed frequency AC power source, the shaft position of the compressor is detected in accordance with the phase difference, and the current of the motor is turned off at the timing of a particular phase difference when the load torque becomes minimum, thus reducing vibration when the compressor is stopped.

Abstract: There is disclosed a maintenance reminder system for a pump. The system of the invention is coupled to the pump or the control system for the pump and determines the volume of fluid pumped by the pump. In the preferred embodiment, a piston pump is used and piston strokes are counted and converted to total volume of liquid pumped. The computer of the system maintains a database for each maintenance item containing the threshold value for each item and the total volume pumped since the last maintenance. When the total volume exceeds the threshold, a maintenance reminder is displayed and the user may display information from the database as to which item needs service. The computer updates the appropriate fields of the database after the service is performed.

Abstract: In some implementations, a controller may obtain an indication of a first crank angle associated with a first pump, of a dual-pump single-power source system, that is mechanically connected to a power source of the dual-pump single-power source system via a first clutch. The controller may obtain an indication of a second crank angle associated with a second pump, of the dual-pump single-power source system, that is mechanically connected to the power source via a second clutch. The controller may determine that a difference between the first crank angle and the second crank angle is outside of a tolerance of a crank angle difference value. The controller may modulate a fluid pressure associated with at least one of the first clutch or the second clutch to cause the difference between the first crank angle and the second crank angle to be within the tolerance of the crank angle difference value.

Abstract: A control device for a fuel injection system includes a CPU which generates a drive signal for instructing execution of compression by a fuel pump; a fuel pump drive circuit which controls application of electric power to a solenoid of the fuel pump based on the drive signal; a boost circuit provided with a capacitor for storing electric power to be used for driving an injector; a charging circuit which leads a current generated when the application of electric power to the solenoid is stopped to the capacitor; and an excess electric power consumption circuit which consumes excess electric power of the capacitor. While fuel injection from the injector is stopped, the CPU counts the number of times the fuel pump is driven and turns off the drive signal so as to stop driving the fuel pump as soon as the drive count has exceeded a predetermined count value.

Abstract: A liquid soap dispenser, which controls positive and reverse rotations of a motor and a liquid discharge amount through angle counting, includes a front cover, a back cover, a liquid soap bottle, a pump component, a main engine and a key. An angle counter is arranged in the main engine. The liquid soap dispenser is connected with the motor. The angle counter is driven to rotate through the motor, so as to measure a rotation angle of the motor. The motor is connected with a gearbox, and the gearbox is connected with an output gear. The output gear is fastened at a lower part of the pump component, and the pump component is driven to move through the output gear. The liquid soap dispenser realizes a stepless adjustment of the liquid discharge amount through controlling the motor to reversely rotate.

Abstract: A method for operating a peristaltic pump having a molded flow channel contained on an elastomeric sheet that is bonded or mechanically attached to a rigid substrate. The pump head rollers are mounted radially from the axis of rotation of the pump motor and compress the elastomeric flow channels against the rigid substrate. During reflux, the pump head is positioned so that at least one of the rollers compresses the elastomeric flow channel at the input end of the peristaltic pump. Such an operation minimizes the amount of the elastomeric sheet that is exposed to high transient pressures.

Abstract: A gradient liquid feed pump system capable of liquid feed in a correct mixing ratio even in the case of liquid feed in which the mixing ratio varies. Specifically, it comprises a first plunger pump for sucking and delivering an eluate, a second the first and second plunger pumps through a cam, a first pressure sensor for measuring the pressure in the flow path of the second plunger pump, a second pressure sensor for measuring the pressure in the fist plunger pump, a cam position detecting sensor for detecting the cam position, wherein when the cam position is in a delivery interval, the rotary speed of the motor is increased, and the period for decreasing the rotary speed is determined on the basis of the difference between the pressure values obtained from the first and second pressure sensors, respectively. Thereby, liquid feed can be smoothly effected with correct mixing ratio while avoiding pressure interference between pumps.
