Abstract
PURPOSE: To make a submerged pump with a built-in semi-open type impeller automatically reverse its revolution when it bites a foreign matter and resume its normal operation as the foreign matter is removed.
CONSTITUTION: When a foreign matter is bitten in between an impeller base plate 4a and the upper wall of a suction port fitting 11 during the pump operation, a semi-open type impeller 4 fitted slidable through a bellows type sealed spring 5 to the tip of a pump shaft 6 retrocedes. This makes the base plate 4a push a control unit 13a to actuate a hermetic limit switch 13 fixed to the side wall 3a through an O-ring 14 and seal guide 15, which exites a coil 17 of relay R to change over contacts 18, 19 and reverses the revolution of a motor M. When the foreign is removed by the reversed revolution, the impeller 4 is reset by the spring 5, the relay R is demagnetized and the motor M resumes normal revolution.
