渣浆泵的维护保养
为使泵安全经济地运行,应注意日常的维护。维护保养请注意以下几个方面:
5.1轴封的维护
定期检测轴封水压和水里。对于付叶轮加添料组合式密封,要求始终保持少里清
水沿轴流过,定期调整填料压盖的松紧并定期更换填料;对于机械密封,要确保高压
轴封水的供给。轴封水压、水量应符合要求。(如2.3所述)
5.2叶轮的调整
为使泵合理运行,对于付叶轮填料组合密封式渣浆泵,应及时调整叶轮的轴向间
隙。一般地,对付叶轮加添料密封型式的泵,叶轮向前调整有利于泵性能,向后调整
可增强轴封效果,故用户可根据实际需要调整。调整叶轮间隙时应首先停泵,然后按
前述叶轮调整方法进行即可。
5.3轴承闰滑
定期检查托架中轴承和润滑油的情况,一般采用20*、 30"或40°机械闰滑油。在首
次运转300小时后换油。正常运装后,轴承温度小于500C时,建议每运转3000小
时换一次油;轴承温度大于50C时,建议每运转2000小时换- -次油。用户可以根据
实际情况确定换油周期。

Maintenance of slurry pump
In order to make the pump run safely and economically, we should pay attention to the daily maintenance. Please pay attention to the following aspects for maintenance:
5.1 maintenance of shaft seal
Check the water pressure of shaft seal and water regularly. It is required to keep the clearance less at all times for the combined seal with additional materials added to the impeller
Water flows along the shaft, regularly adjust the tightness of the packing gland and replace the packing; for mechanical seal, ensure high pressure
Supply of shaft seal water. The water pressure and water quantity of shaft seal shall meet the requirements. (as described in 2.3)
5.2 adjustment of impeller
In order to make the pump run reasonably, the axial space of the impeller should be adjusted in time for the slurry pump with impeller packing combination seal
Gap. Generally, the impeller forward adjustment is beneficial to pump performance and backward adjustment to deal with impeller adding material seal type pump.
It can enhance the effect of shaft seal, so the user can adjust it according to the actual needs. When adjusting the impeller clearance, stop the pump first, and then press
The impeller adjustment method can be carried out.
5.3 bearing leap slip
Check the condition of bearing and lubricating oil in the bracket regularly, generally using 20 *, 30 "or 40 ° mechanical leap lubricating oil. In the first place
Change oil after 300 hours of secondary operation. After normal operation and installation, when the bearing temperature is less than 500C, it is recommended to operate every 3000 hours
When the bearing temperature is higher than 50c, it is recommended to change the oil every 2000 hours. Users can
Determine the oil change cycle according to the actual situation.
