BJ清水离心泵特点
1、清水离心泵系根据标准ISO2858所规定的性能和尺寸设计的,主要由泵体、泵盖、叶轮、轴、密封环、轴套及悬架轴承部件等组成。
2、清水离心泵的泵体和泵盖部分,是从叶轮背面处剖分的,即通常所说的后开门结构形式。其优点是检修方便,检修时不动泵体,吸入管路,排出管路和电动机,只需拆下加长联轴器的中间联接件,即可退出转子部分进行检修。
3、清水离心泵的壳体(即泵体和泵盖)构成水泵的工作室。叶轮、轴和滚动轴承等为泵的转子。悬架轴承部件支撑着泵的转子部分,滚动轴承受泵的径向力和轴向力。
4、清水离心泵为了平衡泵的轴向力,大多数泵的叶轮前、后均设有密封环,并在叶轮后盖板上设有平衡孔,由于有些泵轴向力不大,叶轮背面未设密封环和平衡孔。
5、清水离心泵的轴向密封环是由填料压盖,填料环和填料等组成,以防止进气或大量漏水。泵的叶轮如有平衡,则装有软填料的空腔与叶轮吸入口相通,如叶轮入口处液体处于真空状态,则很容易沿着轴套表面进气,故在填料腔内装有填料环通过泵盖上的小孔,将清水离心泵室内压力水引至填料环进行密封。泵的叶轮如没有平衡孔,由于叶轮背面液体压力大于大气压,因而不存在漏气问题,故可不装填料环。
6、为避免轴磨损,在轴通过填料腔的部位装有轴套保护。轴套与轴之间准有O型密封圈,以防止沿着配合表面进气或漏水。
7、清水离心泵的传动方式是通过加长弹性联轴器与电动机联接的,泵的旋转方向,从驱动端看,为顺时针方向旋转
BJ型泵为单级单吸悬臂式离心清水泵,该泵是在B型泵的基础上增加机械密封,提高效率。供输送清水及物理化学性质类似于水的液体之用。流量范围为4.5~360米 3 /时;扬程范围8~98米;液体zui高温度不超过80 o C,适用于农田排灌,也可用于工矿企业,城市给水排水。
型号说明:100BJ35A
100---吸水口径直径为100毫米
BJ---单级单吸悬臂式离心清水泵,装机械密封
35---所输送液体的扬程35米
A---同型号泵叶轮直径减少(扬程及配带功率亦相应减少)
BJ型泵结构简单,轻巧适用易与维护保养,尤其适应于广大农村实用,泵体出水口方向可根据安装使用条件作90 o C,1800 o C,270 o C旋转,(150BJ33及200BJ29两种规格只能作60 o C,120 o C,180 o C,210 o C旋转)。出水法兰上被又安装压力表之螺纹孔。
水泵之旋转方向从传动之方向看为顺时针旋转,与电机及内燃机等通过弹性联轴器或皮带装置等进行传动。泵轴支以单列向心球轴承,轴承采用黄油润滑。
