1、启动时防止空气吸入泵内,起密封作用。
2、抽水时防止水从泵内过多的沿轴大量流出。

使用与保养:Use And
Maintenance
1、经常检查轴承温度,轴承箱内应装70%的钙基黄油,不得过多或过少,轴承升温一般不得比周围超过35°C,轴承的极限温度不得超过75°C(用手摸感到烫手),若超过应停车检查原因予以消除。


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 and 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 or coupling.
