ISW型卧式管道离心泵产品概述

  ISW型卧式离心泵根据IS型离心泵与立式泵的独特结构组合设计,并严格按照国际标准ISO2858和新的国家管道离心泵标准JB/T53058-93进行设计制造的高效节能产品。该泵采用国内先进水力模型优化设计而成。同时根据使用温度、介质等不同在ISW型基础上派生出热水泵、高温泵、化工泵、油泵等,是目前国家标准定型推广产品。


ISW型卧式管道离心泵型号意义

  例如:ISW100-160(I)AB

  ISW-卧式离心泵

  100-泵进、出口公称直径(mm)

  160-叶轮名义直径(mm)

  I-流量分类

  AB-叶轮经第一、二次切割

ISW型卧式管道离心泵产品特点

  1、运行平稳:泵轴的绝对同心度叶轮优异的动静平衡,保证平稳运行,绝无振动。

  2、滴水不漏:不同材质的硬质合金密封,保证了不同介质输送均无泄漏。

  3、噪音低:两个低噪音轴承下的水泵,运转平稳,除电机微弱声响,基本无噪声。

  4、故障率低:结构简单合理,关键部分采用国际一流品质配套,整机无故障工作时间大大提高。

  5、维修方便:更换密封、轴承、简易方便。

  6、占地更省:出口可向左、向右、向上三个方向,便于管道布置安装,节省空间。


ISW型卧式管道离心泵主要用途

  1、ISW型管道离心泵,供输送清水及物理化学性质类似于清水的其他液体之用,适用于工业和城市给排水,高层建筑增压送水,园林灌溉,消防增压及设备配套,使用温度T:≤80℃。

  2、ISWR(WRG)型热水(高温)循环泵广泛适用于能源、冶金、化工、纺织、造纸、以及宾馆饭店等锅炉高温热水增压循环输送及城市采暖系统循环用泵,ISWR使用温度T:≤120℃、WRG使用温度T:≤240℃。

  3、ISWH型卧式化工泵,供输送不含固体颗粒,具有腐蚀性,粘度类似于水的液体,适用于石油、化工、冶金、电力、造纸、食品、制药和合成纤维等部门,使用温度T:-20℃-120℃。

  4、ISWB型卧式油泵,供输送汽油、柴油、煤油等石油产品,使用温度T:-20℃-120℃。


ISW型卧式管道离心泵使用条件:

  1、吸入压力≤1.0Mpa,或泵系统高工作压力≤1.6Mpa,即泵吸入口压力+泵扬程≤1.6Mpa、泵静压试验压力为2.5Mpa,订货时请注明系统工作压力。泵系统工作压力大于1.6Mpa时应在订货时另行提出。以便在制造时泵的过流部件和联接部分采用铸钢材料。

  2、环境温度<40℃,相对湿度<95%。

  3、所输送介质中固体颗粒体积含量不超过单位体积的0.1%,粒度<0.2mm.

  注:如使用介质为带有细小颗粒,请在订货时说明,以便采用耐磨式机械密封。

1、安装前应仔细检查泵体流产内有无硬质物,以免运行时损坏叶轮和泵体。

2、安装时管路理量不允许加在泵上,以免使泵变形,影响正常运行。

3、拧紧地脚螺栓,以免起动时振动对泵性能产生影响。

4、在泵的进、出口管路上安装调节阀,在泵出口附近安装压力表,以控制泵在额定工况内运行,确保泵的正常使用。

5、排出管路如装逆止阀应装在闸阀的外面。

6、泵的安装方式分为硬性联接安装和柔性联接安装。


ISW型卧式管道离心泵起动与停车

  (一)运行中的维护与保养

  1、进口管道必须充满液体,禁止泵在汽蚀状态下长期运行。

  2、定时检查电机电流值,不得超过电机额定电流。

  3、泵进行长期运行后,由于机械磨损,使机组噪音及振动增大时,应停车检查,必要时可更换易损件,机组大修期一般为一年。

  (二)机械密封维护与保养

  1、机械密封润滑应清洁无固体颗粒。

  2、严禁机械密封在干磨情况下工作。

  3、起动前应盘动泵(电机)几圈,以免突然起动造成密封环断损坏。

  4、密封泄漏允差3滴/分,否则应检修。


故障原因及排除方法

故障现象可能产生的原因排除方法
1、水泵不出水a、进出口阀门未打开,进出管路阻塞,流道叶轮阻塞。a、检查,去除阻塞物
b、电机运行方向不对,电机缺相转速很慢。b、调整电机方向,坚固电机接线
c、吸入管漏气。c、拧紧各密封面,排除空气
d、泵没灌满液体,d、打开泵上盖或打开排气阀
泵腔内有空气。排尽空气
e、进口供水不足,e、停机检查、调整(并网自来水
吸程过高,底阀漏水。管和带吸程使用易出现此现象
f、管路阻力过大,泵选型不当。f、减少管路弯道,重新选泵。
2、水泵流量不足a、先按1.原因检查。a、先按1.排除
b、管道、泵流产叶轮部分阻塞、b、去除阻塞物
水垢沉积、阀门开度不足重新调整阀门开度。
c、电压偏低c、稳压。
d、叶轮磨损d、更换叶轮。
3、功率过大a、超过额定流量使用。a、调节流量关小出口阀门。
b、吸程过高。b、降低
c、泵轴承磨损。c、更换叶轮
4、杂音振动a、管路支撑不稳。a、稳固管路
b、液体混有气体。b、提高吸入压力、排气
c、产生汽蚀。c、降低真空度
d、轴承损坏。d、更换轴承
e、电机超载发热运行。e、搞整按5。
5、电机发热a、流量过大、超载运行。a、关小出口阀。
b、碰擦。b、检查排除。
c、电机轴承损坏。c、更换轴承。
d、电压不足。d、稳压。
6、水泵漏水a、机械密封磨损。a、更换。
b、泵体有砂孔或破裂。b、焊补或更换。
c、密封面不平整。c、修整。
d、安装螺栓松懈。d、坚固。
