T/GS系列高效单级双吸 中开泵   

                                 

● 概 述

T/GS系列单级双吸中开 离心泵是我厂引用国外先进的双吸泵技术,采用国外最优秀的水力模型,在原TS型单级双吸离心泵 基础上开发的新产品;与原TS型泵相比,升级后 的产品除秉承原产品平衡性好、振动小、安装维修方便外,还具有效率高、结构更紧凑、强度刚度高、抗汽蚀性能好、轴封可用机械密封或填料密封、通用范围广等优点。
TGS系列产品主要适用 于自来水厂、空调循环用水、建筑供水、灌溉、排水泵站、电站、工业供水系统、消防系统、船舶工业、亦适合炼油工业中一般性用途;输送介质为清水或物理、化学性质类似于水的其它液体,介质温度不超过80℃,固体量不大于 80mg/L。零件采用特殊材 质,也可输送海水及含有悬浮物的雨水和工业废水。
结构特点
TGS型泵主要由泵体、 泵盖、叶轮、轴系部件、联轴器部件、排气管部件、回水管部件等零部件组成,泵的进、出口均在水泵轴心线下方,与轴线垂直呈水平方向,泵壳为水平中开,检修时不需拆卸管路和电机。高扬程、大口径泵采用双蜗壳型式减少 径向力,减少振动和噪声,轴承受力小寿命长,进口无漩涡,运转平稳损耗低。同一转子部件可用于反向,轴完全密封、不接触介质、不腐蚀螺纹、运行寿命长。
轴承:采用深沟球 轴承支承,用油脂润滑。
轴封:填料密封或 机械密封,填料水封水或机封冷却冲洗水由回水管部件从泵压出室引入或由外部接入。
传动:泵通过弹性 联轴器由电机直接驱动,从电机端看泵为顺时针方向旋转,根据用户需要也可生产为逆时针方向旋转。

注:材料可根据用 户要求选配。

注意事项

①泵安装之前,确 认基础地板调平,设备水平度良好后再进行灌浆。泵和电机联轴器必须调整对准同心度,纠正长途运输颠簸造成的轻微错位。如果是挠性联轴器,并不能补偿任何明显的失调,失调可能引起快速的磨损,噪音,振动和设备的损坏 。

② 设备安装以后,要 连接吸入和排出管道,请勿用泵作为管道支架,所有管道均不能用泵做支撑,安装附件时,注意管道应多用直管少用弯管,以减少水头损失。在使用弯管时,泵进出口前后的直管部分应至少为管径直径的5~10倍长。吸入管必须 保持一定的直度,不能过长,吸入管口要安装底阀。使用的吸入管径最好至少应比泵吸入口大一个等级而不能比泵吸入口小。吸入管道的安装应逐渐上升,请勿把卧式管道的任何部分装的高于泵吸入口。

③ 泵吸入管终端必须比 最低液面低1m,

④ 出口管道上装闸阀 和止回阀,止回阀能阻止停机时回流对泵的损害(泵厂对因未装止回 阀造成的损坏不负责任)

⑤填料压盖不要拧 得太紧,少量的泄漏可以使填料得到润滑,如停止泄漏将会引起填料烧损或轴套擦伤。

⑥启动泵时,请点 试转向,确保电机接线正确。然后请逐渐慢慢打开出口阀,在任何时候请勿长时间关阀运行。

⑦ 启动泵之前,必须 先灌满引水。

⑧请勿尝试在运行 设备附近进行保养,检修或清理。以免造成安全事故。
