1 选购 选购单相潜水电泵应根据具体情况而定。粗选方面是,相同品牌的水泵整体重者为正品;性能方面,扬程应留有余地,流量适中,电压等级相符;制造工艺方面,表面应细腻,壳体厚薄均匀,电缆绝缘良好,接口密封好。购买时可通电试转一下,以启动迅速、无噪声、水管口出风均匀为好。3～5min停机时,叶轮部位无摩擦引起的温升。再待几分钟,泵体无温升、无渗油、无其他气味即为合格产品。 2 使用 每次使用前,应查看水管是否畅通,电缆有无破损,转动部分是否灵活。电源电压不得低于190V,电源
1 optional purchase single-phase submersible pump should be based on the specific circumstances. Crude selection is that the same brand of pumps as a whole are heavy; performance, the head should leave room for moderate flow, voltage levels match; manufacturing process, the surface should be delicate, uniform shell thickness, good insulation of the cable, the interface seal it is good. Buy electricity can try to turn around to start quickly, no noise, water pipe outlet uniform as well. 3 ~ 5min downtime, no friction caused by the impeller temperature rise. Wait a few minutes, the pump body temperature, no oil, no other smell is qualified products. 2 Use Before each use, you should check whether the water pipe is smooth, the cable is damaged, the rotation part is flexible. Power supply voltage not lower than 190V, power supply
