1. With the growing scale of warship, the section area and external gauge of winding cable in warship degaussing system has also increased, which brings difficulties for construction technique. 随着舰船不断的大型化，舰船消磁系统中绕组电缆的截面积、电缆外径也在增大，这给建造施工工艺带来了较大的困难。
2. Mechanical seal is the key part of submersible sewage pump, the reliability of it decide the submersible sewage pump life. 作为潜水污水泵关键部件的机械密封，其可靠性决定潜水污水泵的使用寿命。
3. Note: the parameters of model JYWQ aut-stirring submersible sewage pump are identical to those of model WQ submersible sewage pump (see the table above), see the next page for the out-form dimensions. 说明：JYWQ型自动搅匀潜水排污泵性能参数等同WQ型潜水式排污泵（见上表）。外形尺寸见下页。
