深井潜水泵长期在水下工作,其电缆线接头的密封性是关键问题,尽管使用说明书对密封性都有较详细的说明,但操作起来并不简单。若水渗入,则会造成线圈短路而烧毁电机。 潜水泵引线与电缆线连接时,电缆的三根导线应呈阶梯形错开,削掉绝缘层,刮净导体绝缘漆膜,不得损坏导体,然后用砂纸擦亮,保持接头干净、无水、无油污,再把三根导线各分成数小股。潜水泵的三根引线也按此方法处理。最后,将这两种接线分别均匀地叉在一起,用刮掉漆膜的漆包线缠绕扎紧,再用焊锡将三个接头各焊一 Deep submersible pumps work underwater for a long time and the tightness of their cable connections is a critical issue. Although the instructions for use refer to the tightness in more detail, it is not easy to operate. If the water infiltration, it will cause the coil short circuit and burn the motor. When the submersible pump leads are connected with the cables, the three wires of the cables should be staggered in steps, cut off the insulation layer, scrape the conductive insulating varnish film, do not damage the conductors, and then use sandpaper to polish the joints clean, dry and free of oil , Then the three wires are divided into several small stocks. Submersible pump three lead also according to this method. Finally, the two kinds of wiring were evenly forked together, with the enameled wire scraping paint film wrapped tightly, and then solder the three joints of a welding
