注意事项:

1、操作注意事项

A、泵只允许在规定的参数范围内运转;

B、泵不允许在吐出阀门关闭或关到很小开度下运转。否则导致泵发热,降低寿命。如果泵是安装在一个并联系统中,每台泵都要在特定的参数下运行以保障泵的流量;

C、泵不能关闭吸入口阀门运行。否则使泵发生干转,导致泵零件损坏;

D、泵输送介质不能含有空气或者气体,否则会使泵的流量和扬程不可能准确的测出,同时会产生研磨损坏零件。


2、泵启动前检查

A、启动泵前,应先盘动转子,检查转子是否灵活;

B、检查全部螺栓、管路引线的联接是否紧固和泵周围的安全情况;

C、检查全部仪表、阀门及仪器是否正常

D、检查油环位置、油位计的油位是否正常;

E、检查电动机的转向是否与泵的转向一致。


3、泵的启动

A、打开泵的吸入阀和水封水管路的阀;

B、关闭泵的出口闸阀、压力表旋塞;用输送的液体或抽真空系统排除吸入管和泵体内空气;泵内无液体时不允许启动,否则会损坏零件。

C、启动电机,待泵运转正常后,打开压力表旋塞,慢慢开启泵出口闸阀,观察压力表和开关的指示,按出口压力表读数控制泵给定的扬程。


4、泵的运行

A、本型泵靠内平衡机构平衡轴向力,平衡装置有平衡液体流出,平衡液体由平衡水管接至吸入段或在平衡室外设置一短管,平衡液体经短管流向泵外,为保证泵正常运行,平衡水管绝对不允许堵塞;

B、本型泵滚动轴承均无冷却装置,轴承温升变化反映了泵的装配质量,轴承温升不得高于环境温度35摄氏度,最高温度不应高于75摄氏度;

C、本型泵转子在运行中存在一定的轴向游动,应保证电机和水泵两联轴器端面间的间隙值;

D、泵在运行期间每隔一定的时间应检查仪表、泵的转速和叶轮、密封环、导叶套、平衡盘、轴套的磨损情况,磨损量过大时应及时更换。此外,监测泵的流量、扬程、温度及润滑情况;泵在发生故障时,应停泵,且参考故障排除表进行维修。


5、泵的停机

停机前应先关压力表旋塞,慢慢关闭出口闸阀,待出口阀门关闭完毕后再停电机,当泵停稳后在关闭泵的吸入阀。


6、泵的维修

为了保持泵高效稳定的工作状态,泵必须经常维修,维修的项目和每次维修的间隔时间取决泵的工作条件和泵的运行状况。定期检查泵的性能(如流量、扬程、振动等)而且要做记录,按这些记录数据去分析泵是否正常工作,是否需要维修或者确定要修的哪一部位。在一般条件下,如果坚持精密的测试、记录,定期的总结记录,那么,每隔几个月就可以得到泵是否需要维修的可靠资料。除在规定时间对泵监测外,下面的维护是经常的;

A、检查泵底座、泵、电机是否紧固,如果松动会引起泵的振动;

B、检查仪表、引线的状况,检查管路是否泄露或松动,或其他形式的损坏。如果需要应立即检修;

C、填料压盖不能压的过紧,否则会影响填料寿命;

D、轴承润滑油每工作1000小时更换一次。

故障处理:

装配拆卸:

1、泵的拆卸

拆卸时应严格保护零件的制造精度不受损伤:拆卸穿杆的同时应将各中段用垫垫起,以免各中段止口松动下沉将轴压弯•


注意亊项:

a、将泵壳内的液体放掉:

b、如果轴承部件是稀油润滑时应将润滑油放掉;

c、拆去妨碍拆卸的附属管路,如平衡管、水封水管等管路和引线,


拆卸顺序:

泵的拆卸步骤应从拆下吐出側的轴承部件开始,其顺序大致如下(因泵的结构有所差别.在拆卸过程中会略有不同):

a、柠下吐出侧轴承压盖上的螺栓及吐出段、填料函体、轴承体三个零件之间的连接螺母卸下轴承部件乙:

b、拧下轴上的圆螺母,依次卸下护套、轴承内圈(轴承)、有孔轴承压盖、挡水圈后,卸下填料体(包括填料压盖、填料环和填料等):

c、依次卸下轴上的O型密封圈、轴套、平衡盘和键后,卸下吐出段(包括末级导叶、平衡环、平衡套等);

d、卸下末级叶轮和键后,卸下中段(包括导叶):按同样方法依次卸下其余各级的叶轮、中段和导叶,直到卸下首级叶轮为止:

e、拧下吸水段与轴承体的连接螺母和轴承压盖上的螺栓后,卸下轴承部件甲(在这之前应先将泵联轴器卸下);

f、将轴从吸入段中抽出,拧下轴上的锁紧螺母,依次将轴承内圈、O型密封圈、轴套和挡套等卸下。


至此拆卸工作基本完成,但在上述拆卸过程中,还有部分零件是相互连接在一起的,一般情况下拧下连接螺栓或螺母后即可卸下。


2、泵的装配

清洗和检查:

a、用煤油清洗全部的零件,在空气中干燥或用布擦干;

b、检查全部零件的磨损情况,对不能确保正常运转的零件应更换;

c、检查泵轴是否有灰尘或生锈,用千分表检查轴的不宜度(轴的径向跳动值不大于8级精度);

d、当密封间隙超过推荐值的最大值50%时,应更换密封元件。


泵的装配顺序一般是按拆卸顺序反向进行;

本型泵装配质量的好坏直接影响泵能否正常运行,并影响泵的使用寿命和性能参数;影响机组的振动和噪音。装配中应注意以下几点:

a、固定部分各零件组合后的同心度靠零件制造精度和装配质量来保证,应保护零件的加工精度和表面粗糙度、不允许磕碰、划伤。作密封剂用的二硫化钼应干净,紧固用的螺钉、螺栓应受力均匀。

b、叶轮出口流道与导叶进口流道的对中性是依各零件的轴向尺寸来保证。流道对中性的好坏直接影响泵的性能,故泵的尺寸不能随意调整。

c、泵装配完毕后,未装填料前,用手盘动泵转子,检查转子在壳体内旋转是否灵活、有无摩擦响声,轴向窜动量是否达到规定要求。

d、上述检查符合要求后,在泵两端轴封处加入填料,注意填料环在填料腔中的位置。


【泵的安装】

泵的安装步骤一般包括把泵放在基地上,找水平,调正和联接泵的管路等。


1、泵安装时需要的设备

泵安装时需要下列常规的专用的设备和工具:

a、有负载能力合适而安全的起重设备;

b、每个地脚螺钉处都必须备有一块垫铁或楔铁,作找平底座用;

c、灌浆的材料必须是不收缩的灌浆料。为了灌浆需要准备一个木盒,而且需配有漏斗;

d、安装和拆卸填料,需要一套专用的工具,如带钩的夹具等。


2、泵的搬运在搬运泵时需要注意安全以防事故发生,搬运时要注意下列事项:

a、在搬运泵时,起重机的吊钩应挂在底座下面:也可以用叉式起重机搬运泵,不允许吊在泵的原动机的螺栓孔或吊泵的轴承体,更不能在泵轴处起吊;

b、起重负载应均匀平衡,且应注意起重设备的承载能力,起吊时应小心谨慎,防止泵件的碰撞,特别应避免泵联轴器处轴加工配合面的损坏。

c、严禁异物或者灰尘在搬运过程中掉入泵和电动机内


3、泵的开箱检查

泵运到使用单位后因开箱检查泵的零件是否丢失,是否在运输过程中有损坏,如果出现由于丢失或者顺坏时,应立即向运输部门或者制造厂声明。


4、暂时库存

如果泵在安装以前需要库存一段时间,泵仍然需要包装,而且应该放在干燥、防雨、防灰尘的合适的地方上。泵的吐出口和吸入口应覆盖,以防异物掉入,泵的轴,轴承和其他精加工零件应注意防潮,要应涂保护油层。


5、泵的基础

a、泵的基础必须具有足够的强度,基础的质量应等于机组质量的3-5倍,泵的地基应比泵的底座长50-70cm,且要留出地脚螺栓孔(为地脚螺栓3-5倍的钢管直径);

b、打地基包括如下内容:地基的地脚螺栓孔的定位,灌浆和留出外连接管路位置,然后在其余空间灌浆,地基的表面可是粗糙的,一边灌浆效果好。

c、地基完全固化后安装设备。


6、搬放和找水平

a、在底座下面放置钢的垫铁和楔铁或调整垫,一般都放置在地脚螺栓处。如果底座较长,在两地脚螺栓中间可放置一块垫铁;

b、检查底座下面的地基,清洗飞尘,油和其他杂物。

c、起重吊钩吊住底座的四个角上,把底座吊在地基上方,慢慢地把底座放在每个螺栓孔的位置上(对地脚螺栓孔的位置)

d、用一个刀口平尺和机械水平仪放到安装泵和电机底脚加工平面上,用调整楔铁或调整垫的厚度来确定底座在各个方位上的水平,推荐每100毫米长度不平度小于0.25毫米,这时地脚螺栓的螺母拧到适当程度(不能过紧),楔铁或调整垫片应紧固。

e、底座找平,而且和地基配合较紧后才灌浆。


7、底座的灌浆

a、灌浆时,确保做到每个空间的空气必须全部排出

b、当灌浆材料固化后,拧紧地脚螺栓的螺母,然后再对灌浆材料油漆防潮

c、灌浆后,进行泵和发动机的调正工作


8、设备的调整

设备调整包括角度的调正和中心线位置的调正,至少应在下面三个时期检查设备,进行调正。

第一次:泵和底座已经把紧,但电动机没把紧;

第二次:泵和电动机已紧固,但吸入和吐出管路法兰的螺栓没紧固;

第三次:在泵运转24小时后,再检查一次,检查后把泵和电动机最后紧固。


9、在调正工作中应注意以下事宜:

a、电机与水泵组合安装时,应将泵联轴器端轴伸向外拉出,再保证泵和电机两联轴器之间的轴向间隙值。

b、泵只能承受自身内力,不能承受任何外力。

c、在调正以前,检查全部的管线,保证它们不对泵座产生作用力和力矩;

d、在调正泵和电动机时,垫片应垫在电动机的下面。


角调正是保证联轴器的两个平面的平行度。用一块千分表去检查联轴器法兰端面上的四个点,千分表读为0.02~0.03;检查其平行度也可以用塞尺,两联轴器平面间的差值(a-b)≤0.06.中心线对中是指泵和电动机轴中心线的对正程度。


10、主要管路的联接

泵灌浆后且紧固在地基上以后,在不受外力条件下对正且连接泵法兰和管路的法兰;这个对正联接不能依靠法兰螺栓的力。对管路支撑(附加)应避免管路系统的振动。应减少管路对泵的外加力。为了防止泵的损坏,在泵管路连接以前,要对管路系统进行清洗。


安装管路,应注意事项:

a、使用管路的规格和长度应合适且有足够的承压能力;尽量减少管路的转弯和附件;

b、泵的吸入管路应是短而直。管路直径应大于或等于泵的吸入口的直径,泵的吸入管路的弯曲半径应做成尽量大。


11、附件设备的联接

压力表:在吸入管路和吐出管路上用的压力表必须是质量好,性能合格的仪表。吐出压力表最好装配在泵吐出法兰2倍直径长的距离上,不能装在弯管和闸阀的旁边。以防受不稳定流动的干扰。

联轴器:泵的电动机联轴器连接以前重新检查其对中性;检查电动机的转向是否符合要求,如果电动机转向不符合泵的转向,必须把电动机转向调正过来。

轴封:如果需要,在泵运转以前,重新调整轴封或重新装配。
