Double-sealing device for cable of submersible motor of mute in-pipe pump

The utility model discloses a silent in-pipe pump submersible motor cable double-sealing device, which comprises a base, one end of the base is welded with a pump casing, a through hole and a mounting hole which are positioned on the same axis are respectively arranged in two ends of the base, the through hole is close to the pump casing and communicated with the mounting hole, and the aperture of the mounting hole is larger than that of the through hole. A step surface is formed at the joint of the mounting hole and the through hole; a first sealing structure is arranged in the mounting hole, a second sealing structure is arranged at the end, away from the pump shell, of the base, and one end of the second sealing structure abuts against one end of the first sealing structure. The first sealing structure and the second sealing structure are adopted, double sealing is achieved, the sealing effect is better, and safety and reliability are higher. 本实用新型公开了一种静音管中泵潜水电机电缆双重密封装置，包括一端与泵壳焊接的底座，所述底座的两端内分别设置有处于同一轴线上的通孔
