销售德国力士乐REXROTH叶片泵,REXROTHZG办事处 原装进口 支持验货 价格优惠
REXROTH叶片泵本身机械故障。叶轮与泵轴紧固螺母松脱或泵轴变形弯曲,造成叶轮多移,直接与泵体摩擦,或轴承损坏,都有可能降低水泵转速。
REXROTH叶片泵因其有可变量输送、自吸能力强、可逆转、能输送含固体颗粒的液体等特点,在污水处理厂中,广泛地被使用在输送水、湿污泥和絮凝剂药液方面。螺杆泵选用应遵循经济、合理、可靠的原则。如果在设计选型方面考虑不周,会给以后的使用、管理、维修带来麻烦,所以选用一台按生产实际需要,合理可靠的螺杆泵既能保证生产顺利进行,又可降低修理成本。
现在市场上的螺杆泵的种类较多,相对而言,进口的螺杆泵设计合理,材质精良,但价格较高,服务方面有的不到位,配件价格高,订货周期长,可能影响生产的正常运行。
国内生产的大都仿制进口产品,产品质量良莠不齐,在选用国内生产的产品时,在考虑其性价比的时候,选用低转速,长导程,传动量部件材质优良,额定寿命长的产品。
REXROTH叶片泵决不允许在断料的情形下运转,一经发生,橡胶定子由于干摩擦,瞬间产生高温而烧坏,所以,粉碎机完好,格栅畅通是螺杆泵正常运转的必要条件之一,为此,有些螺杆泵还在泵身上安装了断料停机装置,当发生断料时,由于螺杆泵其有自吸功能的特性,腔体内会产生真空,真空装置会使螺杆泵停止运转。
REXROTH叶片泵是一种容积式回转泵,当出口端受阻以后,压力会逐渐升高,以至于超过预定的压力值。此时电机负荷急剧增加。传动机械相关零件的负载也会超出设计值,严重时会发生电机烧毁、传动零件断裂。为了避免螺杆泵损坏,一般会在螺杆泵出口处安装旁通溢流阀,用以稳定出口压力,保持泵的正常运转。
REXROTH叶片泵只不过是离心泵的一种具体应用的泵而命名。实质上砂泵只是一个笼统的叫法。一般主要用在矿业,煤炭,冶金,化工,环保等行业。一般意义的砂泵更多是指用在环保,挖沙,河道清淤等行业较多。这个系列砂泵主要以ES或者G系列的较多。除此之外,叫做砂泵的类型还有很多,石油领域的SB砂泵,矿业上的PS砂泵系列等等。本文介绍的砂泵主要以通常意义上的ES或G系列的挖沙,环保行业的用的砂泵。
REXROTH叶片泵均为卧式、单泵壳结构的离心泵。采用特殊的卡箍夹紧泵体与泵盖,泵的吐出口方向可在360度的任何一个位置,安装使用方便。 砂泵的轴承组件采用圆筒式结构,便于调整叶轮与泵体之间的间隙,维修时可整体拆除。轴承采用油脂润滑。砂泵的轴封形式有填料密封、付叶轮密封、机械密封。砂泵流道宽畅,汽蚀性能好,效率高,耐磨蚀。 传动方式主要有V型三角带传动、弹性联轴器传动、轮减速箱传动、液力偶合器传动、变频驱动装置,可控硅调速等。 过流部件材质采用高硬度的耐磨合金铸铁。销售德国力士乐REXROTH叶片泵,REXROTHZG办事处 原装进口 支持验货 价格优惠
