渣浆泵启动时要留意什么

date.png 2019-12-12 10:45:29

渣浆泵是一款被宽泛的运用在选矿厂之中的建筑,渣浆泵具有着耐磨、运用寿命长、服从高等特点。渣浆泵是由泵头架构、托架布局、轴封形式这三大片面所构成,那接下来就让渣浆泵厂家的小编来为您介绍一下渣浆泵建筑启动时要留意甚么吧。

一、渣浆泵启动前,需搜检机器密封的附设装置,冷却润滑系统是否完善畅通。

二、应冲洗物料管线,以防铁锈杂质进入密封腔内。

三、用手盘动联轴器,搜检轴是否轻松扭转,如果盘动很重,需搜检相关安装尺寸是否正确。

四、需举行静压实验,搜检机器密封之端面、密封圈处和密封端盖处之密封效果,如有问题,逐一搜检办理。

五、渣浆泵启动前,应保持密封腔内填塞液体或被密封之介质,如有独自密封系统应起动之,冷却水系统亦须先流通。

六、行常压运行,观察密封部位的温升是否平常,是否有走漏征象,如有轻细走漏,可以跑合一段光阴,使端面贴合得加倍匀称,至走漏量渐渐削减到平常为止,如运行1—3小时,走漏量仍不削减,则需泊车搜检。

七、升压升温可分别迟钝举行,并留意端面的温升和走漏环境,如全部平常,分析即可投入生产运用了。


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.
