PROBLEM TO BE SOLVED: To provide an operation control method of a uniaxial eccentric screw pump capable of keeping a seal line in a normal state by making operation at the time of starting or stopping smooth and stable, in the uniaxial eccentric screw pump rotating a stator in a followable manner at a half rotational frequency of a rotor with rotational force of the rotor.SOLUTION: An operation control method of a uniaxial eccentric screw pump 1 rotates, at the time of starting the uniaxial eccentric screw pump, a rotor 42 in a reverse rotational direction by only a predetermined angle at a lower angular acceleration and a lower angular speed than those at the time of normal operation, and then transfers to normal operation after repeating normal rotation and reverse rotation at the predetermined angle a plurality of times. |
