（六）轴上的挡水圈可防止水沿泵轴流入轴承体内，不锈钢混流泵销售价，从而保护轴承，处长使用寿命。
VI.The water deflector of axile can stop the water
running into the bearing body through the pump axile which
can protect
the bearing and lengthen the service life .
（一）安装原则
1、安装高度：视雨季或旱季不同情况具体考虑，要求吸上真空高度不超过泵的吸程。
2、安装位置的选择:尽可能靠近水源，机械密封混流泵销售价，做到既保证安全、又缩短进水管路，减少扬程损失。
混流泵
（二）泵盖是泵与进水管相连的零件，大流量混流泵销售价，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.
注意功率是否突然增大或降低，流量扬程是否突然减少，如有应停车检查。
Pay more attention
to know if the power suddenly increases or reduces，混流泵销售价， if the flow and head are
suddenly lessen， if it is， pls stop to check.
3、经常注意检查各部分螺丝是否因振动而松动，如松动应随时上紧。
Check all parts
screws if they are loose， tighten them after finding.
