ROTATION SPEED CONTROL METHOD FOR SUBMERGED MOTOR PUMP LOADED ON DRAINAGE PUMP VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a rotation speed control method for submerged pump loaded on a drainage pump vehicle capable of controlling rotation speed of the submerged motor pump without providing a frequency conversion device. ;SOLUTION: Output frequency of a power generator 14 is controlled by manually or automatically adjusting rotation speed of an internal combustion engine 10 when rotation speed of a submerged motor pump 22 that is loaded on the drainage pump vehicle and started or operated by power of the power generator 14 driven by power of the internal combustion engine 10.;COPYRIGHT: (C)2001,JPO
