潜水泵之水泵选购技巧及常见故障及解决方法

发布日期:2017-12-03 作者:上(shang)海申霸泵业有限公司 点击:

1、无法启动首(shou)先应检查电源(yuan)供(gong)电情况:接(jie)头连接(jie)是(shi)否(fou)牢(lao)靠;开关接(jie)触是(shi)否(fou)紧(jin)密;保险(xian)丝(si)是(shi)否(fou)熔断;三相供(gong)电的是(shi)否(fou)缺相等。如(ru)有(you)断路、接(jie)触不(bu)良、保险(xian)丝(si)熔断、缺相,应查明原(yuan)因并及时(shi)进行修复。其次检查是(shi)否(fou)是(shi)水(shui)泵(beng)(beng)自身的机械(xie)故障,常见的原(yuan)因有(you):填料(liao)太紧(jin)或(huo)叶轮与泵(beng)(beng)体之间被杂物卡住(zhu)(zhu)而(er)堵塞;泵(beng)(beng)轴(zhou)(zhou)(zhou)(zhou)、轴(zhou)(zhou)(zhou)(zhou)承(cheng)、减漏环锈住(zhu)(zhu);泵(beng)(beng)轴(zhou)(zhou)(zhou)(zhou)严重弯曲(qu)等。排除(chu)方(fang)法:放松填料(liao),疏通引水(shui)槽;拆开泵(beng)(beng)体清除(chu)杂物、除(chu)锈;拆下泵(beng)(beng)轴(zhou)(zhou)(zhou)(zhou)校正(zheng)或(huo)更换(huan)新的泵(beng)(beng)轴(zhou)(zhou)(zhou)(zhou)。


2、水泵发热原因:轴(zhou)(zhou)(zhou)承损坏;滚动轴(zhou)(zhou)(zhou)承或(huo)托架(jia)盖(gai)间隙过小;泵轴(zhou)(zhou)(zhou)弯(wan)曲或(huo)两(liang)轴(zhou)(zhou)(zhou)不同心;胶带太紧(jin);缺(que)油或(huo)油质不好;叶轮上的(de)(de)平(ping)(ping)衡(heng)孔(kong)堵塞(sai),叶轮失去(qu)平(ping)(ping)衡(heng),增(zeng)大了向一边的(de)(de)推力。排除方法:更换(huan)轴(zhou)(zhou)(zhou)承;拆(chai)除后盖(gai),在托架(jia)与轴(zhou)(zhou)(zhou)承座之间加(jia)装垫(dian)片;调查泵轴(zhou)(zhou)(zhou)或(huo)调整两(liang)轴(zhou)(zhou)(zhou)的(de)(de)同心度(du);适当调松胶带紧(jin)度(du);加(jia)注干净的(de)(de)黄(huang)油,黄(huang)油占轴(zhou)(zhou)(zhou)承内空隙的(de)(de)60%左右;清(qing)除平(ping)(ping)衡(heng)孔(kong)内的(de)(de)堵塞(sai)物(wu)。


3、流量不(bu)足(zu)这是因为:动力转速不(bu)配套或皮带打滑,使转速偏低;轴流泵叶片安装角太小(xiao);扬程(cheng)不(bu)足(zu),管路太长或管路有直角弯;吸程(cheng)偏高;底(di)阀、管路及叶轮(lun)(lun)局(ju)部堵塞或叶轮(lun)(lun)缺损;出(chu)水(shui)(shui)管漏水(shui)(shui)严重。排除方法:恢(hui)复额(e)定转速,清除皮带油垢,调整好(hao)皮带紧度;调好(hao)叶片角,降低水(shui)(shui)泵安装位置,缩短管路或改变管路的弯曲(qu)度;密封水(shui)(shui)泵漏气处,压紧填料;清除堵塞物,更换叶轮(lun)(lun);更换减(jian)漏环(huan),堵塞漏水(shui)(shui)处。


4、吸不(bu)上(shang)水(shui)(shui)(shui)(shui)原(yuan)因是泵(beng)体内有(you)空(kong)气或(huo)进水(shui)(shui)(shui)(shui)管(guan)积气,或(huo)是底阀(fa)关闭(bi)不(bu)严灌引水(shui)(shui)(shui)(shui)不(bu)满、真(zhen)空(kong)泵(beng)填料严重(zhong)(zhong)漏(lou)(lou)(lou)(lou)气,闸阀(fa)或(huo)拍门关闭(bi)不(bu)严。排(pai)除(chu)方(fang)法:先把水(shui)(shui)(shui)(shui)压(ya)上(shang)来,再将泵(beng)体注满水(shui)(shui)(shui)(shui),然后(hou)开(kai)机。同时检查逆止阀(fa)是否严密(mi),管(guan)路、接(jie)头(tou)(tou)有(you)无漏(lou)(lou)(lou)(lou)气现(xian)象,如发现(xian)漏(lou)(lou)(lou)(lou)气,拆卸后(hou)在接(jie)头(tou)(tou)处涂上(shang)润滑油(you)或(huo)调合漆,并拧(ning)紧螺(luo)丝(si)。检查水(shui)(shui)(shui)(shui)泵(beng)轴的(de)(de)油(you)封(feng)环,如磨损严重(zhong)(zhong)应更换新件。管(guan)路漏(lou)(lou)(lou)(lou)水(shui)(shui)(shui)(shui)或(huo)漏(lou)(lou)(lou)(lou)气。可(ke)(ke)能安(an)装(zhuang)时螺(luo)帽(mao)拧(ning)得不(bu)紧。若渗漏(lou)(lou)(lou)(lou)不(bu)严重(zhong)(zhong),可(ke)(ke)在漏(lou)(lou)(lou)(lou)气或(huo)漏(lou)(lou)(lou)(lou)水(shui)(shui)(shui)(shui)的(de)(de)地(di)方(fang)涂抹水(shui)(shui)(shui)(shui)泥(ni),或(huo)涂用沥青油(you)拌和(he)的(de)(de)水(shui)(shui)(shui)(shui)泥(ni)浆。临时性的(de)(de)修理(li)可(ke)(ke)涂些湿(shi)泥(ni)或(huo)软肥皂。若在接(jie)头(tou)(tou)处漏(lou)(lou)(lou)(lou)水(shui)(shui)(shui)(shui),则(ze)可(ke)(ke)用扳手拧(ning)紧螺(luo)帽(mao),如漏(lou)(lou)(lou)(lou)水(shui)(shui)(shui)(shui)严重(zhong)(zhong)则(ze)必须重(zhong)(zhong)新拆装(zhuang),更换有(you)裂纹(wen)的(de)(de)管(guan)子(zi);降低扬(yang)程,将水(shui)(shui)(shui)(shui)泵(beng)的(de)(de)管(guan)口(kou)压(ya)入水(shui)(shui)(shui)(shui)下(xia)0.5m。


5、剧烈(lie)震(zhen)动(dong)主要有以下几个原因(yin)(yin):电动(dong)转(zhuan)子不(bu)平衡;联(lian)轴器(qi)结(jie)合不(bu)良;轴承磨损弯(wan)曲;转(zhuan)动(dong)部(bu)分(fen)的零件松动(dong)、破裂(lie);管路支架不(bu)牢(lao)等(deng)原因(yin)(yin)。可分(fen)别采取调整、修理、加固(gu)、校直、更换等(deng)办(ban)法(fa)处理。 上述情况(kuang)是(shi)(shi)造成水泵(beng)故障的常见(jian)原因(yin)(yin),并(bing)不(bu)是(shi)(shi)全部(bu)原因(yin)(yin),实(shi)践中处理故障,因(yin)(yin)实(shi)际分(fen)析,应(ying)遵循先外后(hou)里的原则,切莫盲目操作。

水泵安装:

1.在地理环境许(xu)可的(de)(de)(de)条件下,水(shui)泵应(ying)(ying)尽量(liang)靠近水(shui)源,以减少吸水(shui)管的(de)(de)(de)长(zhang)度。 水(shui)泵安装处的(de)(de)(de)地基应(ying)(ying)牢固,对(dui)固定式泵站应(ying)(ying)修专(zhuan)门的(de)(de)(de)基础。

2.进水管路应密(mi)封可靠,必须(xu)有专(zhuan)用支撑,不(bu)可吊在水泵(beng)上。装有底阀的进水管,应尽量使底阀轴线与水平面垂(chui)直(zhi)安装,其轴线与水平面的夹角不(bu)得小于45°。水源为渠(qu)道时,底阀应高于水底0.50米(mi)以上,且加网防止杂(za)物进入泵(beng)内。

3.机、泵底座应(ying)水平,与基础(chu)的联(lian)结应(ying)牢固。机、泵皮带传动时,皮带紧边在下(xia),这样传动效率(lv)高,水泵叶轮(lun)转向应(ying)与箭头(tou)指示方向一(yi)致;采用(yong)联(lian)轴器传动时,机、泵必须同轴线。

4.水泵的(de)安装位置应满足允许吸上真空高(gao)度(du)的(de)要求,基(ji)础必须(xu)水平、稳(wen)固,保证动(dong)力机械的(de)旋(xuan)转(zhuan)方向(xiang)与水泵的(de)旋(xuan)转(zhuan)方向(xiang)一(yi)致。

5.若(ruo)同一机(ji)(ji)房内有多台机(ji)(ji)组,机(ji)(ji)组与机(ji)(ji)组之(zhi)间(jian),机(ji)(ji)组与墙壁之(zhi)间(jian)都(dou)应有800mm以(yi)上的距离(li)。

6.水(shui)(shui)(shui)(shui)泵吸水(shui)(shui)(shui)(shui)管必须密封(feng)良好,且尽(jin)(jin)量减少(shao)弯头(tou)和闸阀,加注引水(shui)(shui)(shui)(shui)时应排尽(jin)(jin)空气,运行时管内不应积聚空气,要求吸水(shui)(shui)(shui)(shui)管微呈上斜与水(shui)(shui)(shui)(shui)泵进(jin)水(shui)(shui)(shui)(shui)口联接,进(jin)水(shui)(shui)(shui)(shui)口应有一定的淹没深(shen)度。
