Abstract
The utility model discloses a submersible motor waterproofness testing device which includes a pressure container, an air compressor, and a driving part. The pressure container includes an end cover and a container body. The end cover is movably connected with the container body. The driving part is connected with the end cover. The driving part can drive the end cover to contact with or separate from the container body. The end cover is provided with a compressed air tube. One end of the compressed air tube is communicated with the inside of the container body, and the other end is connected with the air compressor. The pressure container is filled with a liquid medium. When the end cover contacts with the container body, the air compressor can fill the pressure container with the air having a preset pressure. Through detecting the insulating property of a submersible motor under the extreme pressure, the submersible motor waterproofness testing device can judge the waterproofness of the submersible motor under the actual working condition water pressure, so the time is saved, and the detection efficiency of the submersible motor is improved.
