（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，工业混流泵销售，保持规定的轴向间隙）。间隙过小产生磨擦，雨水混流泵销售，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，球铁混流泵销售， contrary， if the gap is too large， the pressure water in
pump will reflux which
makes the
feeiciency reduced.adjust the --- washer&make the gap be stated one.
水泵的传动方式
我厂生产的hw型系列混流泵均可用柴油机、电机带动，其传动方式视各地区动力情况而定，订货时根据原动机的型号（功率、转速）确定水泵的传动方式，以确定皮带轮的大小或联轴器的规格。
iv. drive mode of pump
our hw
seriel mixed-flow pump can be driven by diesel engine&motor.the drive mode
can be chosen according to the local motive power situation. when placing an
order for the pump， we should decide the drive mode of the pump according to
the prime motor type(power， rotate speed) in order to confirm the size of
pulley/coupling.
轴套用来保护轴不使它与填料直接摩擦，若长期使用中发现轴套磨损过多，福州市混流泵销售，必须换轴套。
iv. axile sleeve is used to protect the axle from friction
with padding.in long term using， change the axile sleeve
when the sleeve wears down too much.
（五）水泵轴的两个支承是轴承体内的轴承，轴承体内存有适量润滑脂以润滑轴承。
v. two supportings of water pump axile are bearings in
bearing body.there is some lubricating grease in bearing
body for lubricating bearing.
