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。
Check the bearing temperature
regularly.The bearing box should be put 70% butter,it can not be too much or
too little.The temperature rising of bearing can not be more than 35°C higher
than around temperature and the limiting temperature of bearing is 75°C,if the temperature is higher than 75°C, stop to check the reason and adjust it.
8、水泵在冬季使用时，停车后应将水泵内和管道内的存水放尽以防冻裂。
If use the pump
in winter, pls run off the water from the pump and pipes.
9、水泵每使用一个灌溉季节后，应更换润滑黄油后存放。
Replace the
lubricating oil after using the pump for one irrigation season.
10、水泵工作满500小时，应仔细拆卸检查零件的磨损情况，如长期停用，应将运转部分拆下擦干上油妥善保管。
2、水泵起动后有一股水就不出水了
After starting ,
the pump only send one stream water then no water runs out
1、吸入的水中有过多气泡
2、吸水管中窝存空气
3、吸水管或连接处垫料不严密有进气现象
4、底阀或叶轮有水草杂物填塞
1.There are too many bubbles in the
indrawn water
2.There is air in the suction pipes
3.The paddings in connected parts are
imprecision and produces leaking phenomenon
4.There are waterweeds and sundries
filled in the bottom valve or impeller
1、检查进水管末端是否在水平面以下一米左右
2、排除空气
3、高速垫料，填塞缝隙拧紧螺栓
4、消除水草杂物
1.Check the end
of water inlet pipe if it is under the water surface at one meter
2. Remove the
air
3.Add padding to
fill the gaps and then tighten the bolts
4.Clear the
waterweeds and sundries.
