FINE AIR BUBBLE GENERATOR AND FINE AIR BUBBLE GENERATING DEVICE WITH DIAPHRAGM USED IN A DIAPHRAGM PUMP

摘要

A fine bubble generator of a pre-suction pump type is provided to reduce the noise greatly by making water sucked through pre-treatment of a diaphragm pump type motor. A fine bubble generator uses a pressurizing type circulation motor(200). The fine bubble generator of a pre-suction pump type sucks water by mounting a diaphragm type pump(100) in pre-suction in a method of circulation after pre-suction. A suction motor is installed before the circulation motor to have more strong pressurizing method. A pre-diaphragm type pump is installed on the fine bubble generator using the circulation motor. The air control function is controlled in a suction portion. A size of a controlling hole is controlled by a discharge portion.
