FIELD: engines and pumps.
SUBSTANCE: invention is related to method and device for control of helical rotor pump operation. Method for control of helical rotor pump operation consists in the fact that internal dimensions of stator are adapted to conditions that occur in process of pump operation, affecting stator cartridge consisting of elastic material, which is adjacent to stator jacket along its whole length. Stator cartridge axial length is varied, while stator cartridge is adjacent to jacket with the possibility of its free movement, by stretching or compressing force applied only from one stator end. For uniform distribution of stretching or compressing force stator cartridge is extended for shortened along contact surfaces passing parallel to longitudinal axis of pump.
EFFECT: provision of for pump adaptation to different working conditions without variation of pump length and with minimum expenditures for assembly and installation.
