脱硫泵算是泵产品中应用较为宽泛的一种,不过要想延长脱硫泵的寿命,就要记得日常的保护。要想脱硫泵能安全运行,寿命长,必须留意日常的保护,保护养护应留意以下几个方面:

1、轴封的保护:

填料轴封泵要定期检验密封水压和水量,要始终保持少量洁净水沿轴流过了,定期调填料压盖,搜检填料并定期更换填料,轴封水压,轴封水量应合乎上述(轴封搜检)要求。

2、叶轮的调节:

为了包管泵高效运行,就必须及时调整叶轮与前护板的间隙,调节叶轮间隙时停泵,松开压紧轴承盒的螺栓,松开调整螺母,使轴承组件向前挪动,同时用手滚动轴按泵的滚动方向扭转,直到叶轮与前护板磨擦为止,再用调整螺栓使转子后移,记下前后挪动间隙,平衡分派在叶轮前后护板之间,到达叶轮与前护板、后护板之间间隙相等为止并将两防尘盘调紧,紧固在轴上。调整后,在再次起动前须从新搜检叶轮滚动是否平常,轴承组件压紧螺栓是否拧紧,而后复兴动泵。

3、轴承润滑:

轴承组件在装置时,若装置正确,润滑油适量,维修及时,运输寿命会较长,维修人员应定期检验轴承组件,搜检轴承及润滑油的情况,在运行中须定期增加或更换润滑油,隔断光阴及注入的量与泵的转速、轴承规格、连续事情光阴、泵的停开次数,四周情况和运行温度等许多因素相关,是以须渐渐蕴蓄堆积履历,合理及时地加润滑油。

4、备用泵应每周将轴滚动1/4圈,以使轴承匀称地蒙受静载荷和外部振动。

Desulfuration pump is widely used in pump products, but if you want to extend the service life of desulfuration pump, you should remember the daily protection. In order to ensure the safe operation and long service life of the desulfurization pump, attention must be paid to the daily protection. The protection and maintenance shall pay attention to the following aspects:


1. Shaft seal protection:


The sealing water pressure and water volume of the packing shaft seal pump shall be inspected regularly. A small amount of clean water shall always flow along the shaft. The packing gland shall be adjusted regularly, and the packing shall be inspected and replaced regularly. The water pressure of the shaft seal and the water volume of the shaft seal shall meet the above requirements.


2. Adjustment of impeller:


In order to ensure the efficient operation of the pump, it is necessary to adjust the clearance between the impeller and the front guard plate in time. When adjusting the clearance between the impeller, stop the pump first, loosen the bolts that compress the bearing box, loosen the adjusting nuts, and move the bearing assembly forward. At the same time, use the hand rolling shaft to twist it according to the rolling direction of the pump until the impeller and the front guard plate are abraded. Then use the adjusting bolts to move the rotor backward, and record the moving room before and after The clearance shall be evenly distributed between the front and rear guard plates of the impeller until the clearance between the impeller, the front guard plate and the rear guard plate is equal, and the two dust discs shall be tightly adjusted and fastened on the shaft. After adjustment, before starting again, it is necessary to check whether the impeller rolling is normal, whether the bearing assembly pressing bolts are tightened, and then restart the pump.


3. Bearing lubrication:


When the bearing assembly is in the device, if the device is correct, the lubricating oil is appropriate, the maintenance is timely, and the transportation life will be long, the maintenance personnel shall regularly inspect the bearing assembly, search for the bearing and lubricating oil, and regularly increase or replace the lubricating oil during the operation, cut off the time, the injected amount and the rotation speed of the pump, the bearing specification, the time of continuous events, the shutdown and opening times of the pump, the surrounding conditions and the transportation Many factors, such as line temperature, are related to the need to gradually accumulate accumulation history and add lubricating oil reasonably and timely.


4. The spare pump shall roll the shaft 1 / 4 turn every week to make the bearing bear the static load and external vibration evenly.
