METHOD FOR CONTROL OF DOSING PUMP AND/OR REGULATION OF DOSING PUMP Russian patent published in 2015 - IPC F04B49/02 F04B13/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to a method for control of a dosing pump and/or regulation of a dosing pump, which includes a drive motor having a shaft brought into action with the motor and a displacement element located in a dosing head, in which rotating movement of the shaft is converted to an oscillating movement of the displacement element. In order to create a method for control and/or regulation of the dosing pump, at least one operating parameter of the motor, preferably voltage U or current I in the motor is measured. A calculation of at least one controlled parameter is made based on the measured operating parameters. The controlled parameter representing actual torque moment M_ACTUAL of the motor and actual magnetic flux Φ_ACTUAL in the motor is compared to the specified orienting parameter representing at least one specified standard function, a comparison signal is output, which characterises a degree of similarity between the controlled parameter and the orienting parameter. If the degree of similarity takes a value in the specified range of values, the comparison signal is used as a state indication signal.

EFFECT: method can be implemented without any position sensor on a stock and can set a pump operating mode at dosing with a high level of accuracy.
