离心泵有哪些充水方法? 泵阀产品的用户们都应该听我们销售人员介绍过, 离心泵 (除自吸泵外)在启动前都要把水泵和进水管内灌满水,否则水泵是无法扬水工作的。离心泵启动后不出水,往往是由于泵中空气没有被排净、水没有被充满所致。那么,各种离心泵到底有哪些充水方法呢?请看详细介绍:    离心泵启动前的充水方法主要有两种:一种是采用装配底阀充水,底阀为单向阀,装在进水管的进口,这种方法的缺点是底阀水头损失较大,影响了水泵的装置效率;另一种是无底阀充水,此法的最大优点是节能,相对于有底阀的泵站可节能10%~15%。下面介绍几种离心泵的充水方法,供用户在运行水泵时选择。    人工充水法 对于进水管直径小于300mm的小型泵站,在进水管的进口通常设有底阀,一般多采用人工充水法,即从水泵壳上部的专用充水排气孔处由充水漏斗(或一个去掉瓶底的倒立的普通瓶子)充水。对于进水管直径小于300mm的小型泵站,在进水管的进口通常设有底阀,也可以从水泵的出水管口(出水管路较短的泵站)向泵中充水。由于无需购买其他充水设备,在目前农村小型泵站中,这种充水方法比较普遍。    对不设底阀、逆止阀且管路较短的小型泵站,也可以采用一边启动,一边从出水管口向水泵内充水的办法,从而把水泵和管路中的空气逐渐带出,一般连续充水几分钟后,水泵即可正常抽水工作。     真空水箱充水法 对于不设底阀的小型泵站,可采用真空水箱充水法。真空水箱是用铁皮焊制的封闭型水箱,其容积至少为进水管容积的3倍,水箱安装的位置应尽可能靠近水泵,水箱底高也应略低于水泵的轴线。真空水箱的高度一般为水箱直径的2倍。    水泵启动前,先将水箱灌满水进行密封。水泵启动后,水泵从真空箱进水,由于水箱水位下降致使水箱内形成一定的真空,进水池中的水就会在大气压的作用下,经进水管进入水箱中,从而形成水的循环,使水泵开始正常运行。这种充水方法具有如下优点:水力损失小,泵站效率高,技术人员劳动强度低,启动简便,且利于实现水泵机组的自动化控制。    射流泵充水法 用柴油机带动水泵抽水时,可利用柴油机排除的废气通入与水泵顶部相通的射流器,进行抽气充水,从而去掉了水泵的底阀。在水泵启动时,将和手柄相连的阀盖关闭,废气从射流器喷出,通过连管把泵中的空气吸出。充水完毕后把阀盖打开,控制阀关闭。这种充水方法的好处一是充分利用了动力机,二是提高了泵站的效率。    手动泵充水法 作为往复式容积泵的一种,手动泵在我国农村被广泛使用,农民可把自家的手动泵作为 真空泵 使用,对离心泵进行充水,既方便又经济。    最常见的用法是:将手动泵安装在离心泵的抽气孔上或靠近水泵的进水管路上,进行抽气引水,使之成为离心泵开机时充水的工具,从而省掉了水泵进水管路上的底阀,减少了能量损耗,提高了水泵装置的效率。    自行引水充水法 对于采用半淹没式的泵房(即进水管和水泵泵顶的高程均在进水池水面以下的泵站),水可自行引入水泵中而不必人工灌引水。这种泵站的缺点是没有充分利用水泵的吸水能力,同时水泵安装高程降低,不仅增大了基础的开挖量,而且运行管理也较不便;但优点也较明显( 循环水泵 http://xunhuanbeng.scpv.net/),即易于实现泵站的自动化,时效性较强。  自悬引水充水法 自悬引水充水法是利用水和气的容重差,通过“水气置换”原理来实现的。此法可去掉水泵的底阀。    首先,设计一个适量容器的换气罐,换气罐一般为 塑料制品 ,也可为薄铁皮件,成本仅为底阀的二分之一。然后,将换气罐安置在水泵进水口处,与水泵、管路形成一个连通体。同时,在换气罐与水泵之间的换气流道上,安装一个换气控制阀。充水时,预先给换气罐加满水,然后加盖密封,再开启换气阀。换气完毕,关闭换气阀,将有一部分引水悬在进水管中。按照这种方法反复数次,空气将被全部排尽,进水管中也就充满水了。此时,便可启动水泵进行扬水作业。停机前,只要先关闭闸阀再停机,引水将不会回坐。下次启动时就不用再灌引水了。这种充水方法的优点是换气罐价格较低,制造容易,劳动强度低,节约能源。  真空泵充水法 对于进水管直径大于300mm的大、中型泵站,或自动化要求程度较高的泵站,真空抽气装置是常用的一种充水设备。它由真空泵和其他设备组装而成,排灌站经常采用的真空泵大多为水环式真空泵。    水环式真空泵的圆柱形泵壳内安装一个偏心的牙状叶轮。泵壳内注有循环水,在抽真空时,叶轮旋转,在离心力的作用下,泵壳内的循环水被甩至叶轮四周,在泵壳内壁形成一个旋转水环。又因叶轮是偏心安装在泵壳内的,因此水环与牙状叶片之间形成的空间大小不同。叶轮顺时针方向旋转时,其右半部分两叶片之间的空间逐渐增大,在密闭条件下,随着空气体积的增大,压力随之降低,形成真空,水泵和管路内的空气通过吸气管,进入真空泵泵壳右侧的月牙形吸气口被吸入真空泵,真空泵叶轮左半部分两叶片之间的空间是逐渐减小的,因此空气被压缩,压力随之增高,最后通过真空泵泵壳左侧月牙形排气口排出真空泵,进入水气分离箱,使被带出的循环水分离后再重复使用。叶轮不停地旋转,真空泵就不断地吸气和排气,最后将水泵充满水。    关于真空泵的台数,对于小型泵站,当机组少于3台时,一般选1台,当机组多于4台时,一般选2台;对于中大型泵站,最好选用2台,当机组较多时,要考虑备用1台。真空泵充水的优点是充水时间短、泵站效率高、劳动强度低、易于实现泵站自动化。缺点是投资较大。    离心泵充水是水泵运行管理的重要组成部分,相信随着水利科研人员对离心泵充水方法的不断探索,以“方便、实用、高效”为宗旨的水泵充水方法会越来越多,充水效果也会越来越好,从而为机电排灌事业的发展做出积极的贡献。 查看更多 0个回答 . 3人已关注

2014几道案例题? 两天的煎熬,结束了考试,感觉今年的试题知识部分比去年难度增加了不少,尤其是下午那场,几道计算分析题根本就没有做,靠蒙选了。案例还好。就是有几道现在还没有搞明白,有兴趣的大家讨论一下: 1.上午关于加气站的日最大供气能力,只写了教材上的公式,接下来就不会了。因为没有查到汽车罐的压力,即使知道,计算也比较复杂,回头看书也没有查到具体怎么计算,压力多少? 2.下午第2道:4台7MW的燃气水管锅炉(给的是型号,自己判断),热效率90%,燃气低热值36.93MJ/立方,并且给出了组成98%CH4,0.4%C3H6,0.3%C3H8,0.4%C4H10,剩余是 氮气 . 问增加了烟气冷凝设备后,燃气消耗量?不会计算 3.有一道是 链条炉 烟尘浓度计算的,二类区20t/h锅炉,除尘效率95%,q4=10%,Qar.net=188410,测得进入烟囱的烟气量550000立方,水含量3000立方,温度180度,过量 空气 系数1.8,求烟气浓度值,是否符合标准。求得的数值跟答案不符。 4.求高炉涡轮机的功率的,跟教材上的例题一样,数值有变动,但就是没有计算出相符的答案。计算了不下4边,真是郁闷。 5.有一道泵的选配题,直接略过了,没记住。查看更多 10个回答 . 5人已关注

想搞拆分,各位前辈帮帮忙啊? 各位前辈,小弟最近搞手性拆分,由于第一次做,真心不知道如何下手,按照文献做的但是就是拆不出来,小弟现在有这么几个问题问问,各位前辈不吝赐教哈: 1.拆分用的拆分剂用多少当量合适呢?加0.5个当量,还是要加一个当量呢?加过量了或者温度高了那R型的会不会也会跟S型的成盐呢? 2.拆分选用的溶剂是不是要选用溶解度要良好,但又要保证成盐后能析出来的才合适呢 3.拆分是不是一般一次拆不干净 4.是不是只要有氨基或者羧基的东东都可以用拆分办法得到消旋体啊 5.如何选用拆分剂呢? 小弟先谢谢了! 查看更多 11个回答 . 2人已关注
2017年醋酐在爆炸中爆发? 一、价格走势:   根据生意社数据监测显示,2017年前9个月国内醋酐行情基本平稳,9月下旬开始,由于国庆期间的醋酐备货,醋酐行情小幅上涨,之后行情维稳。但由于10月初的一次美国化工厂突发爆炸事件,醋酐行情一路飙升,涨至醋酐均价7350元/吨,涨幅49.66%;其后醋酐厂家为清库存,醋酐行情一度回落至6471.43元/吨,但由于原材料价格一直坚挺,醋酐价格随后大幅攀升,并在12月31日醋酐价格升至7978.57元/吨,全年涨幅62.46%。   二、行情分析:   产能:2017年醋酐全年总产量小幅增长。其中17年新增产能4万吨(南京凤鸣塑化实业有限公司4万吨醋酐设备开工投产),拟在建醋酐项目产能10万吨(山东嘉驰新型化工有限公司新建10万吨醋酐项目)。但由于环保影响,上半年开工率一般,进入10月份,醋酐价格飙升,醋酐厂家最大限度的满负荷开工,但受限于原材料限制和国家限气限电影响,部分企业开工率不足50%,总体全年醋酐产量小幅增加。   上游原材料行情:   由上图可以看出, 醋酸 价格在10月份开始飙升,并且一直到年底价格没有下跌趋势。 甲醇 价格在上半年价格在震荡调整并小幅下滑,但9月中旬开始,甲醇持续增长,并在12月达到顶峰。10月之后,原材料价格上涨推动醋酐价格同步上涨。   企业动态:2017年10月4日,全球最大的醋酐生产企业美国 伊士曼 化学设备爆炸,醋酐生产全线停车。伊士曼化学拥有81.7万吨醋酐设备,是全球最大的醋酐生产企业,其产能占全球醋酐产能的35.5%。伊士曼化学的醋酐设备停车,严重影响了全球醋酐供给,导致全球醋酐供应紧张,国际醋酐需求量增加,国内企业醋酐出口量增加,出口增加加剧了国内供求紧张的趋势,醋酐价格上涨。   进出口行情:2017年1-11月份累计进口醋酐6074.26吨,同比减少49.65%;1-11月份累计出口10955.38吨,同比增多60.16%。进口醋酐减少,出口醋酐增多,促进醋酐价格上涨,在醋酐产能没有重大增长的情况下,醋酐价格暴涨在预料之中。但这次醋酐出口增加并不能持久,随着美国伊士曼化学的设备检修结束,重新开工,醋酐价格势必回落,回归正常。但由于设备检修不可能短期结束,并弥补需求空缺,短期内进口难以增长,出口仍会增加。   三、后市预测:   2017年醋酐经历暴涨之后,在2018年必定价格回落。虽然国内醋酐需求没有明显增加,但全球市场上醋酐需求旺盛,醋酐出口量增加,国内市场醋酐供给略显不足,对醋酐的价格仍有一定的支撑作用,醋酐价格难以回落至2017年水平。生意社数据分析师认为:2018年醋酐价格会迅速回落,或将在2月底价格降到谷底,且这一价格会维持稳定一段时间,并维持在一个较高价位,预计在5500元/吨左右。但随着美国伊士曼化学醋酐设备的全面开工,国际市场醋酐行情的逐步稳定。国内醋酐价格可能还会有一波降价,但这次降价幅度可能不会很大,价格或降至5000元/吨左右。 查看更多 3个回答 . 4人已关注
优化煤的粉碎工艺的必要性!!? 炼焦用煤的粉碎细度和粒度组合成对 焦炭 质量影响较大。不应当把各种没先混合,再去粉碎。要根据不同的煤种(岩相组成的硬度差异),按不同粒度要求进行破碎和筛分。对于硬度较高的气煤等煤种要细破碎,对于易碎的焦煤和肥煤可较大颗粒。不同煤种,分组进行破碎,提出不同的粒度要求,这称作选择破碎煤工艺。这种工艺能够提高煤的结焦性和减少焦炭裂纹,进而提高焦炭质量。要通过试验,优化出本企业的最佳配煤细度的方案,来指导炼焦优化生产。查看更多 15个回答 . 3人已关注
