自吸泵和液下泵的区别,立式液下泵常见的问题有哪些?

时间:2018-6-2 14:56:53来源:http://yeesfab.com作者:弘凌泵阀安徽快3

自吸泵属自吸式离心泵,它具有结构紧凑、操作方便、运行平稳、维护容易、效率高、寿命长,并有较强的自吸能力等优点。管路不需安装底阀,工作前只需保证泵体内储有定量引液即可。不同液体可采用不同材质自吸泵。液下泵适用于长期输送任意浓度的强酸、碱、盐、强氧化剂等多种腐蚀性介质。新型液下泵适用输送轻质易燃易爆物料,具有免维护、防爆、能耗低特点;传统液下泵其壳体,主管,出口管及过流部件全部用塑料合金(PTFE、FEP)模压烧结制成,泵主机部分全部放置在液体内,具有耐腐蚀性强、机械强度高、不氧化、无毒素分解特点。下面我们具体了解一下自吸泵和液下泵区别以及立式液下泵常见问题

自吸泵和液下泵的区别

液下泵安徽快3的特点是可以深入需要输送的介质以下,进行低位输送。结构特点是采用了长轴悬臂结构。液下深度需尽量控制在2米以内,超过则效率大幅度下降。但液下泵大的问题是整个轴为挠性轴,在输送介质的过程中,轴承不断的受到单边磨损,磨损过度则导致轴承晃动,然后又加剧轴承磨损的一个恶性循环。所以液下泵的损坏故障率一直很高。而且磨损较高的部件大部分都在输送介质以下,因此拆卸维修极为不便。

自吸泵安徽快3原理采用独特的专利叶轮及分离盘强制气液分离而完成吸气过程。其外形、体积、重量、效率与管道泵相似。自吸泵不需要底阀、真空阀、气体分离器等辅助设备。正常生产启动时无需灌液,具有很强的自吸能力,可替代目前广泛使用的液下泵(低位液体输送泵),可作分离器等辅助设备、槽车输送泵、自吸管道泵、机动用泵等用途。

4、水流的进出水管中的阻力丧失过大

有些用户经过测量,尽管蓄水池或水塔到水源水面的垂直间隔还略小于液下泵扬程,但还是提水量小或提不下水。其起因常是管道太长、水管弯道多,水流在管道中阻力丧失过大。其起因常是管道太长、水管弯道多,水流在管道中阻力丧失过大。个别状况下90度弯管比120度弯管阻力大,每一90度弯管扬程损践约0。5-1米,每20米管道的阻力可使扬程损践约1米。此外,有局部用户还随便液下泵进、出管的管径,这些对扬程也有肯定的影响,液下泵的安装方法安徽快3也对泵也有很大的影响。
