装配与拆卸
1、YW型液下泵装配顺序
(1)将轴承分别装在轴承体内.
(2)将油封毡圈分别装在轴承体和轴承端盖内。
(3)将机械密封装入轴封体内。
(4)将靠近机械密封的轴承端盖穿在轴上,将O型圈、轴套和装好轴承的下轴承体套装在轴上,用螺栓上紧轴承端盖,将联接管和轴封体分别在下轴承体的上、下端,用螺栓上紧,将轴承端盖装在中间轴承体上,用螺栓上紧,在轴上嵌入键,将联轴套装入轴上,在上轴嵌入键,装入联轴套内,将上联接管安装在中间轴承上,用螺栓上紧,将上述装好部件装在支承盘上并将上轴承体装在支承盘上,用螺栓紧固,上好上轴承端盖。
(5)将泵盖装在轴封体上,并用螺栓上紧,将叶轮键嵌入轴内,然后依次装上叶轮,止退垫圈,用叶轮螺固定好,将泵体装在泵盖上,用螺栓紧固,装上前盖并用螺栓与泵体紧固。
(6)在轴的上端装联轴器部件,并将电机联轴器用紧固螺钉紧固在电机轴头上,将电机与电机座联接牢固。
(7)从泵出口依次将石棉垫、弯头、出水管部件装上,并固定在支承盘上。
安装
1、安装前的装备工作
a、检查水泵和电机有无损坏
b、准备工具及起重设备
c、按图检查基础。
2、将泵的支承座安装在容器上,用螺栓拧紧(如系水泥井罐需预先设置地脚螺栓)。
起动与停止
1、观察泵的安装基础是否已经稳固,所有各部件螺栓是否拧紧。
2、检查泵轴向间隙是否已经调整好(扳动联轴器无摩擦声即可)
3、油标注入钙基黄油
4、检查电机旋转方向是否正确
5、起动电机,打开压力表旋塞,当泵以全转数工作时,调节闸阀开度到需要范围。
6、泵停止工作时,应先停止电动机,然后闭上压力表旋塞。
7、泵长期停止运行时,应将泵拆开,擦拭干净,涂上防锈油妥善保存。
运转
1、注意泵轴承温度,不应超过外界温度35度但最高不应大于75度。
2、油杯内应注满钙基黄油,保证轴承能正常润滑。
3、泵在工作第一个月内,或运转100小时后,应更换电机支承油杯内的黄油,以后每工作2000小时后更换一次。
4、定期检查弹性联轴器,注意电机轴承温升。
5、动转过程中,如发现噪声或不寻常的声音时,应立即停车检查。
6、泵每工作2000小时应进行周期检查,叶轮、泵体(或泵盖)之间间隙的摩损不能过大,间隙的最大值不得超过1.5毫米,如超过可更换叶轮或前盖。
7、泵工作6小时时,应检查机封,根据磨损程度予以检修或更换,否则将导致泵轴及轴承的损坏。
可能发生的故障及其解决方法
故 障
|
原 因
|
解 决 方 法
|
自吸水泵不出水出水,心理压差表游标轻微上下跳动 | 取水部位被淤塞、蒸汽管道与仪盘表漏气 | 排出到淤塞、螺扣或堵塞过漏气处 |
水泵不出水
|
泵进行进水头少于液面、滑动目标方向不会对 |
增高液面或下降泵的安装高度、检查电机转向
|
压力表指示泵出水处有压力、泵仍不出水
|
留水管子阻较大、风机叶轮淤塞、转数不到位 | 定期检查聚氨酯保温管、清理风叶、不断增加泵的转数 |
流量过低
|
水泵电机淤塞、转数过少、离心叶轮破损过大 | 清理泵及管道阀门、增大转数、换个水轮 |
泵消耗功率过大
|
泵自来水量过小(或全关 )、水泵叶轮磨坏 | 进出口管进入设置闸阀、根换风扇叶片 |
轴承过热
|
轴套缺油、轴套内部组织有污垢或受损 | 曾加研磨脂、家电清洗滚动轴承型号或进行更换滚动轴承型号 |
