发明名称 SUBMERGIBLE MOTOR PUMP
摘要 PROBLEM TO BE SOLVED: To provide a submergible motor pump easily and smoothly startable without arranging expensive equipment, reducing the size and causing no damage of a motor. SOLUTION: A motor shaft 5 driven by the motor M is formed as a hollow shaft, and a pump shaft 6 for driving the pump P is inserted into the motor shaft 5. Torque of the motor shaft 5 is transmitted to the pump shaft 6 via a continuously variable transmission T. The transmission ratio of the continuously variable transmission T is steplessly changed so that starting of the pump P and operation thereafter can be smoothly and efficiently performed.
