混流泵
（二）泵盖是泵与进水管相连的零件，其端面与叶轮之间留有规定的轴向端面间隙（在消除轴承轴向活动间隙以后，保持规定的轴向间隙）。间隙过小产生磨擦，过大则会导致泵内压力水回流，使泵的效率降低，通过增减调整纸垫达到规定的间隙。
II. Pump cover is
the part connected with water inlet pipe.There is an stated axial end face gap
between its end
face and
impeller(Keep the stated axail gap after removing the bearing axial movable
gap).Friction will be
produced if
the gap is too ***all, contrary, if the gap is too large, the pressure water in
pump will reflux which
makes the
feeiciency reduced.Adjust the paper washer and make the gap be stated one.
4、注意填料的冷却情况，填料的的调整，不可太紧，以液体能一滴一滴漏出为准，填料太紧发热、消耗功率。填料太松、使水泵中的液体漏损过多，降低效率。
Pay more
attention to the cooling condition of padding.The padding can not be too tight,
it is ok that the fluid can leak in drops.The temperature will be high if the
padding is too tight which cumes power.If the padding is too loose, the
fluid leaks too much, the efficiency will be lower.
磁悬浮潜水电泵是新一代潜水电泵，它实现了立轴磁悬浮(在不同工况下保持率)、不磨损，使用时间及检修周期延长数倍，省去频繁的定期检修工作，可连续运转数万小时，节省维修、检修费用。
潜水排污泵磁悬浮潜水电泵通过了*** 试验室、山东省泵类产品质量检测中心检测。试验数据证明，磁悬浮潜水电泵的转换效率超过传统潜水电泵，用户使用情况结合实验数据及领域内对比，进一步证明其节能、转换效率世界 、单机扬程世界领 及高承载、超大流量、免 修、长寿命等特点!若渗漏不严重,可在漏气或漏水的地方涂抹水泥,或涂用沥青油拌和的水泥浆。
