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.

4、叶轮表面的气蚀。由于叶片背水面运行时产生负压,当压力Pklt;Pva时,产生汽穴和蜂窝表面后,在电化学腐蚀作用下,使泵叶汽蚀。
5、容积损失和机械损失。由于泵使用时间长,机械磨损产生漏失和阻力增大,使容积效率和机械效率降低。
以上原因,使水泵性能变差。运行效率降低2~5%,严重的可以使水泵效率降低10%以上。
