ROTARY PUMP CONTROL SYSTEM Russian patent published in 2016 - IPC F04D15/00 F04D13/06 

FIELD: engines and pumps.

SUBSTANCE: claimed system comprises the controlled parameter master with output connected with the comparator first input. Controlled parameter computer output is connected with the comparator second input. Comparator output is connected with the required rpm computer input. The required rpm computer output is controlled with voltage and frequency control unit, it outputs being connected with frequency inverter inputs. Frequency inverter output is connected with the input of induction motor input AD, motor output being connected to torque transducer input DM and rpm transducer input DC. DM transducer first output of the rotary pump RP is connected with the pump input. Rpm transducer output is connected with the second input of pressure and flow rate computer unit P&FCU. Second output of M transducer is connected with the first input of P&FCU. The first output of P&FCU is connected with the first input of controlled parameters computer unit CPCU. Second output of P&FCU is connected with the second input of CPCU.

EFFECT: decreased specific power consumption, decreased weight and overall dimensions.
