Zusammenfassung:	PROBLEM TO BE SOLVED: To operate all of cyclone pumps equally under given conditions. SOLUTION: The cyclone pump control system 2 comprises a dehydration receiving tank 20 for temporarily storing drained muddy water, six units of cyclone pump 29a-29f for sending the drained muddy water under pressure from the dehydration receiving tank 20, six units of cyclone 30a-30f connected to the cyclone pumps 29a-29f respectively, a pump control part 43 for controlling the driving of the cyclone pumps 29a-29f, an ultrasonic level meter 41 for measuring the liquid level of the drained muddy water temporarily stored in the dehydration receiving tank 20, an arithmetic process part 42 for determining the number of the cyclone pumps 29a-29f to be operated based on the measurement results of the ultrasonic level meter 41 as the required number of the pumps for operation and a timer 44 for measuring the operating time of each of the cyclone pumps 29a-29f.
