泵的辅助管路设置

  1） 暖泵(beng)(beng)(beng)管道(dao)：当(dang)离心泵(beng)(beng)(beng)输送物(wu)(wu)料(liao)温度超过200 ℃ ， 需(xu)设置(zhi)暖泵(beng)(beng)(beng)管道(dao)， 使少量物(wu)(wu)料(liao)由操作泵(beng)(beng)(beng)的排出(chu)管道(dao)引至(zhi)(zhi)备(bei)(bei)用泵(beng)(beng)(beng)出(chu)口(kou)， 然后流经备(bei)(bei)用泵(beng)(beng)(beng)， 回至(zhi)(zhi)泵(beng)(beng)(beng)入口(kou)，使备(bei)(bei)用泵(beng)(beng)(beng)处于热(re)备(bei)(bei)状态(tai)， 便于启(qi)动(dong)。

  2） 防凝(ning)管(guan)道(dao)：对于常(chang)温下易凝(ning)介质的泵(beng)应设DN20 25 的防冻管(guan)， 设置方式同暖(nuan)泵(beng)管(guan)道(dao)。

  3） 平衡(heng)管道：介质在(zai)泵入(ru)口处易发生(sheng)气(qi)化(hua)时(shi)， 可在(zai)泵入(ru)口管嘴与泵入(ru)口切断阀之间设(she)(she)置一根可返回吸入(ru)侧上游设(she)(she)备气(qi)相(xiang)空间的平衡(heng)管， 使产生(sheng)的气(qi)体回流， 避免泵产生(sheng)气(qi)蚀(shi)， 平衡(heng)管上应设(she)(she)置切断阀。

  4） **小回(hui)流(liu)管道：为防止离(li)心泵(beng)在低于泵(beng)的(de)最小流(liu)量运(yun)转， 应设置泵(beng)**小回(hui)流(liu)管道， 使(shi)一部(bu)分流(liu)体(ti)从泵(beng)排出口返回(hui)至泵(beng)吸(xi)入口端的(de)容(rong)器， 以保(bao)证泵(beng)的(de)流(liu)量。

导(dao)致(zhi)离心泵振动(dong)的(de)**原因：

在(zai)转(zhuan)动(dong)设备和流动(dong)介质中，低强度的(de)(de)(de)机械振动(dong)是不(bu)可避免的(de)(de)(de)。但好比人咳嗽一样，久病不(bu)治，必(bi)将酿(niang)成(cheng)大祸。。。下面详(xiang)细介绍离心泵振动(dong)的(de)(de)(de)**原因(yin)，希望对使用单位 有(you)所帮助。

一(yi)、引起离心泵振动的**原因——轴  

轴(zhou)(zhou)(zhou)很(hen)长的(de)(de)泵(beng)，易发(fa)生(sheng)轴(zhou)(zhou)(zhou)刚度(du)不(bu)足，挠度(du)太大(da)，轴(zhou)(zhou)(zhou)系直线度(du)差的(de)(de)情况，造成(cheng)动(dong)(dong)(dong)(dong)件（传动(dong)(dong)(dong)(dong)轴(zhou)(zhou)(zhou)）与静件（滑动(dong)(dong)(dong)(dong)轴(zhou)(zhou)(zhou)承或口环）之间(jian)碰摩，形(xing)成(cheng)振动(dong)(dong)(dong)(dong)。另外，泵(beng)轴(zhou)(zhou)(zhou)太长，受水池中流动(dong)(dong)(dong)(dong)水冲击的(de)(de)影(ying)响较大(da)，使(shi)泵(beng)水下(xia)部分的(de)(de)振动(dong)(dong)(dong)(dong)加(jia)大(da)。轴(zhou)(zhou)(zhou)端的(de)(de)平衡盘间(jian)隙(xi)过大(da)，或者轴(zhou)(zhou)(zhou)向的(de)(de)工作窜动(dong)(dong)(dong)(dong)量(liang)调整不(bu)当，会造成(cheng)轴(zhou)(zhou)(zhou)低频(pin)窜动(dong)(dong)(dong)(dong)，导(dao)致轴(zhou)(zhou)(zhou)瓦振动(dong)(dong)(dong)(dong)。旋转(zhuan)轴(zhou)(zhou)(zhou)的(de)(de)偏心，会导(dao)致轴(zhou)(zhou)(zhou)的(de)(de)弯曲振动(dong)(dong)(dong)(dong)。

二(er)、引起离心泵振动的**原因——基(ji)础及泵支架

驱动(dong)(dong)装置(zhi)架(jia)与(yu)基础(chu)之间(jian)采用的接触固定形式不好，基础(chu)和电(dian)机(ji)系(xi)统(tong)吸收、传递、隔离振动(dong)(dong)能力(li)差，导致基础(chu)和电(dian)机(ji)的振动(dong)(dong)都超标。水泵(beng)(beng)基础(chu)松(song)(song)动(dong)(dong)，或(huo)(huo)者水泵(beng)(beng)机(ji)组在安装过(guo)程中(zhong)形成弹性基础(chu)，或(huo)(huo)者由(you)于油浸(jin)水泡造成基础(chu)刚度减弱，水泵(beng)(beng)就会(hui)产生(sheng)与(yu)振动(dong)(dong)相(xiang)位差1800的另(ling)(ling)一个(ge)临界转(zhuan)速，从而使水泵(beng)(beng)振动(dong)(dong)频(pin)率(lv)增加(jia)(jia)，如果增加(jia)(jia)的频(pin)率(lv)与(yu)某(mou)一外(wai)在因(yin)素频(pin)率(lv)接近或(huo)(huo)相(xiang)等，就会(hui)使水泵(beng)(beng)的振幅(fu)加(jia)(jia)大。另(ling)(ling)外(wai)，基础(chu)地脚螺栓松(song)(song)动(dong)(dong)，导致约(yue)束刚度降低(di)，会(hui)使电(dian)机(ji)的振动(dong)(dong)加(jia)(jia)剧(ju)。

液体在直(zhi)管中流(liu)动时的压力损(sun)失

液(ye)体(ti)(ti)在(zai)直管(guan)(guan)中(zhong)流动(dong)(dong)时的(de)(de)压(ya)(ya)力损失(shi)是由液(ye)体(ti)(ti)流动(dong)(dong)时的(de)(de)摩擦引起的(de)(de)，称之为沿程(cheng)压(ya)(ya)力损失(shi)，它主(zhu)要取(qu)决(jue)于管(guan)(guan)路的(de)(de)长度(du)、内(nei)径、液(ye)体(ti)(ti)的(de)(de)流速(su)和粘度(du)等(deng)。液(ye)体(ti)(ti)的(de)(de)流态(tai)不(bu)同(tong)，沿程(cheng)压(ya)(ya)力损失(shi)也不(bu)同(tong)。液(ye)体(ti)(ti)在(zai)圆管(guan)(guan)中(zhong)层(ceng)(ceng)流流动(dong)(dong)在(zai)液(ye)压(ya)(ya)传(chuan)动(dong)(dong)中(zhong)**为常见，因此，在(zai)设计液(ye)压(ya)(ya)系统时，常希望(wang)管(guan)(guan)道(dao)中(zhong)的(de)(de)液(ye)流保持层(ceng)(ceng)流流动(dong)(dong)的(de)(de)状态(tai)。流体(ti)(ti)在(zai)管(guan)(guan)道(dao)内(nei)流动(dong)(dong)的(de)(de)沿程(cheng)压(ya)(ya)力损失(shi)

一.层流

层(ceng)流(liu)(liu)时的(de)压(ya)力损失在(zai)液(ye)压(ya)传动(dong)中，液(ye)体的(de)流(liu)(liu)动(dong)状态多(duo)数是层(ceng)流(liu)(liu)流(liu)(liu)动(dong)，在(zai)这种(zhong)状态下液(ye)体流(liu)(liu)经直(zhi)管的(de)压(ya)力损失可以通过理论计算求得(de)。

二(er)。紊流(liu)(liu)(liu)时的(de)(de)(de)(de)(de)压(ya)力(li)损失层(ceng)流(liu)(liu)(liu)流(liu)(liu)(liu)动中各质(zhi)点(dian)有(you)沿轴向的(de)(de)(de)(de)(de)规则运(yun)动。而无横向运(yun)动。 紊流(liu)(liu)(liu)的(de)(de)(de)(de)(de)重要特性之(zhi)一是液体各质(zhi)点(dian)不(bu)再(zai)是有(you)规则的(de)(de)(de)(de)(de)轴向运(yun)动，而是在(zai)运(yun)动过程中互相(xiang)渗(shen)混和(he)脉动。这种极(ji)不(bu)规则的(de)(de)(de)(de)(de)运(yun)动，引(yin)起质(zhi)点(dian)间的(de)(de)(de)(de)(de)碰(peng)撞(zhuang)，并形成旋涡，使(shi)紊流(liu)(liu)(liu)能量损失比层(ceng)流(liu)(liu)(liu)大(da)得多。 由(you)于紊流(liu)(liu)(liu)流(liu)(liu)(liu)动现象的(de)(de)(de)(de)(de)复(fu)杂性，完全用(yong)(yong)理(li)论方法加以(yi)研究至今(jin)，尚未(wei)获得令人满意的(de)(de)(de)(de)(de)成果，故(gu)仍(reng)(reng)用(yong)(yong)实验(yan)的(de)(de)(de)(de)(de)方法加以(yi)研究，再(zai)辅以(yi)理(li)论解释，因而紊流(liu)(liu)(liu)状态(tai)下液体流(liu)(liu)(liu)动的(de)(de)(de)(de)(de)压(ya)力(li)损失仍(reng)(reng)用(yong)(yong)式来(lai)计(ji)算，式中的(de)(de)(de)(de)(de)λ值不(bu)仅(jin)与雷诺数(shu)Re有(you)关(guan)，而且与管壁(bi)表面(mian)粗糙度有(you)关(guan)。离心泵比转数(shu)是按水(shui)力(li)学相(xiang)似定律推导出来(lai)的(de)(de)(de)(de)(de)区别(bie)离心泵水(shui)力(li)特性的(de)(de)(de)(de)(de)相(xiang)似特征数(shu)。南通卫生(sheng)泵品质(zhi)好
