摘要： PROBLEM TO BE SOLVED: To provide a liquid pump for generating bubbles that is able to easily generate fine bubbles in a fluid and to discharge the fluid having micro-bubbles incorporated therein and that generates further finer micro-bubbles and is not liable to the reduction in capacity. SOLUTION: The tool A for generating bubbles is composed of a tubular body 10 that causes a liquid to flow through and an annular body 20 that supplies air. The tubular body has a number of micropores 11. The annular body forms a circular air passage 23 in connection with each micropore. The cylindrical body is connected with an air introduction pipe 30 which is connected with the air passage. The liquid pump B1 for generating bubbles is characterized by connecting one end of the annular body of the tool A for generating bubbles with a suction port or a discharge port of the liquid pump. Another liquid pump B2 for generating bubbles is characterized by connecting one end of the annular body of the tool A for generating bubbles with a suction port of the liquid pump that delivers to a discharge port a liquid sucked from the suction port by a blade wheel 54 which rotates at a high speed.

摘要： PROBLEM TO BE SOLVED: To provide an adjustable-speed submerged electric agitator capable of always keeping agitation flow velocity in an agitation tank constant while being continuously worked, even if the agitation tank has a large water-level fluctuating width, being efficient due to low waste of energy, and capable of saving electric power consumption to be low in running cost. SOLUTION: An adjustable-speed submerged electric agitator is provided with a water level sensor 2 which senses water-level fluctuation in an agitation tank 1, a conversion device 3 which receives an output signal from the water level sensor 2 and converts it to an output signal of a coordinate value on a preset conversion output signal curve, an inverter 5 which receives the output signal from the conversion device 3 and supplies a frequency source corresponding to the output signal, a submersible motor 6 which receives the frequency source from the inverter 5 and rotates at the number of rotations corresponding to the water-level fluctuation in the agitation tank 1, and agitating vanes 7 which are fitted to the derived end of the rotary shaft of the submersible motor 6 to rotate.

摘要： PROBLEM TO BE SOLVED: To provide a horizontal underwater electric mixer capable of involving no air even in a state of low water level, providing the sufficient jet stirring effect without generating the vibration, and sufficiently ensuring the suction amount of water. SOLUTION: In this mixer, a guide ring having an annular water discharge port 4A on its front end is connected to an outer periphery of a propeller 2, only an upper edge of a rear end of the guide ring 3 is extended to a rear part of a horizontal underwater motor 1, and a lower end forms a downwardly inclined edge 5 by cutting the neighborhood of a front end lower part of the horizontal underwater motor 1 to an inclined upper rear part. The inclined edge 5 is an opening edge, and a slot-shaped suction port 4B is opened from the neighborhood of the front lower part of the horizontal underwater motor 1 to the rear part.

SOLUTION: An impeller plate 2a is unrotatably restricted at a position rotated by 45 deg. from a horizontal position in anticlockwise direction, and an impeller plate 2b is unrotatably restricted at a horizontal position. Water flow (a) is rotated by reaction bent in a right direction, and a pump casing 1 is rotated in a clockwise direction around an axis L. Water flow (a) is also swung in a clockwise direction. The impeller plate 2a is fixed to a horizontal position, and the impeller plate 2b is fixed to a position rotated by 45 deg. from the horizontal position in a clockwise direction. The water flow (a) is bent in a left side by the impeller plate 2b, and the pump casing 1 is rotated around the axis L in a counter clockwise direction. The water flow (a) is also swung in the counterclockwise direction. The pump casing 1 and the water flow (a) are swung in right and left directions by alternate repeat.
