产品概况
WFB型无密封自控自吸泵主要由泵体、工作叶轮(主叶轮)、副叶轮、泵轴、电机支架、电控阀、停车止回阀等装置组成。工作原理为气液混合式,在泵运转前,泵体内存在一定量的液体,泵启动后,由于工作叶轮的旋转作用。使进液管内的空气与泵体内的液体充分混合,并被排到气液分离室,气液分离室内的空气从上部逸出,液体从下部返回叶轮进口,重新和进液管的剩余空气混合,不断循环,直到把进液管内的空气全部排尽,完成自吸.
工作原理
工作原理:自吸泵的主要水力元件叶轮和泵壳与一般离心泵相似,泵腔内增加了储液室和气水分离室。WFB型无密封自吸泵,无密封应该为副叶轮动力密封,又称为流体动力密封。它可以克服填料密封及机械密封的某些不足,可以确保无泄漏。
副叶轮动力密封原理
副叶轮在工作叶轮上部,运行时和工作叶轮一起旋转,其作用是减低泵腔的压力,达到平衡轴向力和防止液体进入密封装置。副叶轮其实是依靠压力顶住工作叶轮出口处的高压液体向外泄漏,停机时副叶轮不起作用,所以应配备停机密封,防止泵腔水外流。
注意要点
因WFB型立式自吸泵的泵腔内水力损失比一般离心泵要大,所以配用功率相对较大,WFB无密封自控自吸泵的电控阀作为自吸泵的组成部分之一装在吸液口的进气管上,启泵时电控阀密闭泵体吸液管上的进气口,使自吸泵泵腔内形成真空,完成自吸全过程。
停泵时电控阀开启,空气从密闭口进入水泵液管内迅速隔离吸液管内共流的介质,确保泵腔的介质不随吸液管腔内的介质回落到吸液池中,以达到消除虹吸的目的,确保自吸泵二次自吸时正常自吸及运行,自吸泵停机后出口止回阀靠回水重力关闭,使泵腔内液体不会流出。
