小区供暖泵「流量6.3方|扬程300米」18.5KW该泵为双壳体结构。
该设计利用外壳体内的流体压力使内壳体的上下结合面贴紧,
可极力减少
配合止口,
同时增大作用在吸入侧和吐出侧之间的垫片上的紧固压力。
因此该泵不需要其他设
计中常见的用于紧固吸入侧和吐出侧之间的垫片的坚固螺栓。
(2)小区供暖泵「流量6.3方|扬程300米」18.5KW
该泵拆装简单,结构坚固。无需拆卸、移动主管路和原动机等 DG46-30*5多级离心泵,即可操作转子部件。
(3)小区供暖泵「流量6.3方|扬程300米」18.5KW
通过叶轮对称布置,平衡轴向力。因此不需要压力损失大、结构复杂的平衡装置。同时,内壳
体为双涡壳式,径向力也可以被平衡。
(4) 小区供暖泵「流量6.3方|扬程300米」18.5KW由于采用双涡壳式,内壳体及外壳体的温度分布相同
锅炉给水泵安装后的检查和保养对安装后不立即运转的泵,应进行以下检查和保养:通常泵出厂时 DG46-30*4锅炉泵,联轴器、法兰、轴等外部加工表面上涂有防锈油,且泵内部涂有溶剂稀释型防锈油。但是,不立即运转的场合,应在泵内封入干燥剂(硅胶)或防锈剂。
安装后,从排气孔向轴承体内注入一定量的防锈油。防锈油应每年更新一次。为阻挡灰尘、污物和防潮,用苫布盖住泵。
每4个月检查一次泵表面。如有必要,再涂一次防锈油
