多级耐磨离心泵概述

该系列泵采用国家推荐使用的高效节能产品的水力模型，经我厂不断更新研发，具有效率高、性能范围广、运转安全和平稳、噪音低、安装维修便利、运行寿命长等优点，其技术水平处于国内领先地位，产品性能可靠。该系列泵主要用于矿山，其过滤部件及易损坏件均采用了耐磨材质，可供输送固体颗粒含量≤.5％，粒度≤0.5mm，温度在80℃以下的中性矿井水及类似的其他污水。

多级耐磨离心泵执行标准

GB/T5657-1995《离心泵技术条件（III类）》MT114-85《煤矿用耐磨离心水泵技术条件》

多级耐磨离心泵性能范围泵吸入、排出口径：40～300mm流量：3.75～840m/h扬程：19～684m

多级耐磨离心泵运行条件及寿命

在清水条件下（含固体颗粒低于0.1％），运行5000h无大修，效率下降不超过6％

在含固体颗粒0.1％～1％以下污水条件下，运行3000h无大修，效率下降不超过5％

在含固体颗粒1～.5％污水条件下，运行2000h无大修，效率下降不超过6％

多级耐磨离心泵结构特点

MD系列泵系卧式、单吸、分段式多级离心泵，吸入口为水平方向，吐出口与水平垂直向上。泵的进水段、中段、出水段、轴承体待泵壳体部分通过拉紧螺栓联成一体，并根据泵的扬程选择泵的级数。

该系列泵转子部分主要由轴及安装在轴上的叶轮、轴套、平衡盘等零件组成，其中叶轮的数量根据泵的级数而定。轴上零件通过平键和轴螺母紧固使之与轴联成一体。整个转子由两端滚动轴承或滑动轴承支承，轴承按型号不同而定，均不承受轴向力，其轴向力由平衡盘平衡。泵在运行中允许转子在泵壳中轴向游动，不能采用向心球轴承。滚动轴承用油腻润滑，滑动轴承用稀油润滑，并用油环进行自润滑，循环水冷却。泵的进水段、中段、出水段之间的密封面均采用二硫化钼润滑脂密封，转子部分与固定部分之间装有密封环、导叶套等进行密封，当密封环和导叶套的磨损程度己影响泵的工作性能时应予以更换。轴的密封形式有机械密封和填料密封两种。泵采用填料密封时，填料环的位置安放要正确，填料的松紧程度必需适当，以液体能一滴一滴渗出为宜。泵各种密封元件装在密封腔内，腔内要通入一定压力的水，起水封、水冷却或水润滑任凭。在轴封处装有可更换的轴套，以保护泵轴。从原电机方向看，泵为顺时针方向旋转。

另外，本公司能根据用户需求实现该系列泵多出口的结构及功能。

MD系列耐磨多级离心泵的安装

本型泵安装时除满足要救外，还应注意以下几点：

1、安装泵的基础平面应用水平仪找平。基础水泥凝固后，应检查底座和地脚螺栓孔是否松动；2、电机、泵和底座组装后，应检查泵轴和电机轴的同心度，保证两轴心线在同一水平线上；3、电机和水泵组装时，应将泵联轴器端外拉出，保证泵和电机两联轴器端面的轴向间隙值；

4、泵只能承受自身内力，不能承受任何外力。泵的吸入管路和压出管路应有各自的支架，以免将泵压坏。

多级耐磨离心泵的走动、运行和停机起动

1、泵起动前应转动泵转子，检查转子是否灵活；2、检查电机转向是否与泵转向一致；

3、开启泵吸入阀，关闭泵出口管路闸阀及压力表旋塞，使泵内充满液体，或用真空系统排除吸入管和泵内空气；4、检查泵和电机联接螺栓的松紧程度和泵周边的安全状况，使泵处于准备状态；

5、起动电机，待泵运转正常后，开启压力表旋塞，渐渐开启泵出口闸阀，直到压力表指针指到所需压力为止（按出口压力表读数控制泵的扬程）。运行

1、该系列泵靠泵内平衡机构平衡轴向力，平衡装置内有平衡液体流出，平衡液体布平衡水管接至进水段，或在平衡室外设计一短管，平衡液体经短管流几泵外。为保证泵正常运行，平衡水管绝对不允许堵塞；

2、在开车和运行过程中，必需注意观测仪表读数，轴承发热、填料漏水和发热及泵的振动和声音等是否正常，如发现异常状况，应及时处理；

3、轴承温升变化反映了泵的装配质量，轴承温升不向高于环境温度35℃，轴承的最高温度不得高75℃；

4、泵转子在运行中存在一定的轴向力游动，轴向窜动应在允许范围内，应保证电机和水泵两联轴器端面间的间隙值；5、泵在运行期间应定期检查叶轮、密封环、导叶套、轴套、平衡盘等零件的磨损状况，磨损过大时应及时更换。停机

1、停机前应先关闭压力表旋塞，渐渐关闭出口闸阀，待出口阀关闭完毕后再停电机，泵停稳后再关闭泵的吸入阀；2、泵内水放出，如长期停用，应将泵拆卸清洗上油，包装保管。
