一、柴油机双吸泵简介
由于柴油机双吸泵的吸入口和排出口均在泵轴心线下方,柴油机双吸泵的叶轮相当于两个相同大小的单吸叶轮组合在一起工作,在和单级离心泵叶轮一样大小直径的情况下流量可以翻一倍;柴油机双吸泵泵体就是有两个吸水室,特别之处主要还是双吸叶轮的进水方向与单吸叶轮不一样,双吸叶轮的好处就是同样转速与流量的情况下,由于减小了进水口的流速、柴油机双吸泵很难出现汽蚀现象。
柴油机双吸泵的使用范围与卧式离心泵相同,流量范围为90~ 3000m3/h,扬程范围为10 -140m。
其特点是流量大,检修方便,并且检修时只需打开泵盖即可取出转子,不需要拆卸电动机和
连接管路。
柴油机双吸泵泵体是水平剖分的螺旋形蜗壳,两个呈半螺旋形的吸液室与泵壳一起为中开式结构。泵轴水平放置,轴的两侧支撑在装有轴承的轴承座内,双吸式叶轮置于泵轴中间。泵的吸入口及排出口分别布置在下半个泵壳的两侧,泵体和叶轮两侧都装有密封环,轴封装置为填料密封,现在也有改用机械密封的,对称布置在泵体的两侧。在泵盖上设有两根水封管将压力水引入填料函进行水封、冷却和润滑。轴向力可自动平衡,不必设置轴向力平衡装置。检修泵时,不必拆动与泵体相连接的管路。在相同的流量下,柴油机双吸泵比单吸泵的抗汽蚀性能更好。
