（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 small, 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.
3、安装基础：要求土质坚实牢固。
4、水泵安装时，必须保证泵轴的水平位置。
5、进水管末端应浸入水平面以下一米左右，但须离开泥底半米左右。
6、水泵安装好后，计算允许吸上高度和扬程，在水位稳定的条件下，要求为规定数量值的0.8~1.2倍范围，否则水泵不会正常运行
I.
Installation Principle
1. Installation
Height: Cidering the height according to the rainy season or dry season.The suction
vacuum
height can
not be higher than the adsorbing height.
2. Installation
Location:The location is better to close to the water source as p as
can.It should be not
only
keeping the safety but also shortening the water inlet pipe and reduce the
headloss
3、水泵出水量不足
The waer yield
of water is not enough
1、进水管路或叶轮有水草杂物
2、转速过低
3、输水高度过高
4、泵盖及叶轮磨损间隙过大
5、填料进气
6、马力不足
7、进水管口插入水中深度不够
1. There are waterweeds and sundries in
inlet pipes or impeller
2.The rotate speed is too low
3.Water delivery height is too high
4.The attrition gap between pump cover
and impeller is too large
5.The padding is air in
6.The horsepower is not engough
7.The depth of inlet pipe under water is
not enough
1、清除水草杂物
2、调整转数
3、降低输水高度
4、用纸垫调整间隙至正常
5、压紧或更换填料
6、加大马力
7、增加插入水中深度至一米左右
1.Clear the waterweeds and sundries
2.Ajust the rotate speed
3.Reduce the water delivery height
4.Add paper washers to adjust the gaps
5.Compact or change padding
6.Increase the horsepower
7.Make the depth of inlet pipe under
water to one meter
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!6、要仔细检查叶轮上是否有裂痕，叶轮固定在轴承上是否有松动，如果有出现裂缝和松动的现象要及时维修，如果水泵叶轮上面有泥土的也要清理干净。
