The invention relates to air tightness detection equipment for submersible pump production and a detection method. The air tightness detection equipment comprises a reservoir, a bracket, a positioning structure, a second cylinder, a transmission structure and an air supply main body, a piston rod of a second air cylinder drives a vertical plate to move towards a submersible pump motor, the vertical plate drives a horizontal plate to move towards the submersible pump motor, and after the horizontal plate and the vertical plate move to specific positions, a driving structure drives a rotating pipe and an external thread section to be in threaded connection with a top threaded hole or a side threaded hole. The air supply main body injects compressed air into the submersible pump motor through the flexible pipeline, the submersible pump motor is completely immersed in water, the submersible pump motor bubbles to indicate that the assembly is not in place or the motor body is damaged, if the submersible pump motor
