XBD-DL立式多级消防泵型号意义

XBD-DL立式多级消防泵结构图及零部件名名称

XBD-DL立式多级消防泵结构说明

1、 该泵为立式、多级、节段式结构,泵进水段、中段、出水段由拉杆螺栓拉紧固定,每一级上有一叶轮和导叶,轴向力采用水力平衡,残余轴向力由轴承承受。

2、 轴封可选用填料密封或机械密封,选用机械密封时可选用便拆式结构。

3、 泵由电机驱动,从电机端方向看,泵顺时针方向旋转。

4、 泵进水在下方,出水在下方,进出水间相对位置可根据用户要求选择为0°、90°、180°、270°中任一进行装配,如无需要,则为180°,即泵的进出水口分列泵两侧。

5、 该泵可根据用户要求配套相应的控制设备。

6、 泵设有灌引水系统和排气装置。

7、 叶轮可采用青铜材料,避免长期停机后叶轮与导叶间锈合。

8、 泵组可配套隔振器或隔振垫、联接板。

XBD-DL立式多级消防泵安装说明

1、 安装时管路重量不应承受在泵上,否则易损坏水泵;

2、 泵与电机是整体结构,出厂时已由厂家校正,所以安装时无需调整,因此安装时十分方便;

3、 安装时必须拧紧地脚螺栓,且每间隔一定时段应对泵进行检查防止其松动,以免水泵起动时发生剧烈振动而影响泵的性能;

4、 安装水泵前应仔细检查泵流道内有无影响水泵运行的硬质物(如石块、铁砂等)以免水泵运行时损坏过流部件;

5、 为了维护方便和使用安全,在泵的进出口管路上安装一只调节阀及在泵进出口附近安装一只压力表,对于高扬程泵,为防止水锤,还应在出口闸阀安装一只止回阀以应付突然断电等失去动力事故,从而确保水泵在最佳工况下运行,增长水泵的使用寿命;

6、 泵用于有吸程场合,应装有底阀,并且进口管路不应有过多弯道,同时不得有漏水、漏气现象,以免影响水泵的吸入性能;

7、 为不使杂质进入泵内而堵塞流道影响性能,应在泵进口前面安装过滤器;

8、 安装管路前转动水泵的转子部件,应无磨擦声或卡死现象,否则应将泵拆开检查原因。

XBD-DL立式多级消防泵XBD型泵的维护与保养

运行中的维护与保养

1、 进水管路必须高度密封,不能漏水、漏气;

2、 禁止泵在气蚀状态下长期运行;

3、 禁止泵在大流量工况运行时,电机超电流长期运行;

4、 定时检查泵运行中的电机电流值,尽量使 泵在设计工况范围内运行;

5、 泵在运行中应有专人看管,以免发生意外;

6、 泵进行长期运行后,由于机械磨损,使机组噪声及振动增大时,应停车检查,必要时可更换易损零件及轴承,机组检修期一般为一年。

机械密封维护与保养

1、 机械密封润滑液应清洁无固体颗粒;

2、 严禁机械密封在干磨情况下工作;

3、 起动前应盘动泵(电机)几圈,以免突然起动造成机械密封断裂损坏。

XBD-DL立式多级消防泵起动与停车

起动前准备

1、 用手拨转电机,叶轮应无卡磨现象,转动灵活;

2、 打开进口阀门,打开排气阀使液体充满整个泵腔,然后关闭排气阀;

3、 如输送热液体时,起动前应预热,升温速度为50℃/h,泵的预热是用所输送液体不断循环来达到,以使各部位受热均匀;

4、 应先用手盘动几圈以使润滑水进入机械密封端面;

5、 点动电机,确定转向是否正确。

起动与运行

1. 全开进口阀门,关闭吐出管路阀门;

2. 接通电源,当泵达到正常转速后,再逐渐打开吐出管路上的阀门,并调节到所需工况;

3. 注意观察仪表读数,检查轴封泄露情况,正常时机械密封泄漏为3滴/分,检查电机、轴承处温升≤70℃,如果发现异常情况,应及时处理。

停车

1、 逐渐关闭吐出管路阀门,切断电源;

2、 关闭进口阀门;

3、 如环境温度低于0℃,应将泵内液体放尽,以免冻裂水泵;

4、 如长期停用,应将泵拆卸清洗,包装保管。
