进口卧式多级管道泵
一、进口卧式多级管道泵产品概述
进口卧式多级管道泵@德国NOOK诺克系列卧式、单吸多级、分段式结构，是新开发生产的节能系列产品管道泵。具有效率高，运行噪音低，抗汽蚀性能好，结构合理，使用寿命长等显著优点。主要输送清水或物理化学性质类似于水的其他液体。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。轴上零件用平键和轴螺母紧固使之与轴成为一体。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。滚动轴承用油脂润滑，滑动轴承用稀油润滑，并用油环进行自润滑，循环水冷却。泵的吸入段、中段、吐出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已影响泵的工作性能时应予更换。轴的密封形式有机械密封和填料密封两种。WSDJ大多采用填料密封，PXDJ一般采用机械密封。泵采用填料密封时，填料环的位置安放要正确，填料的松紧程度必须适当，以液体能一滴一滴渗出为宜。泵各种密封元件装在密封箱内，箱内要通入一定压力的水，起水封、水冷或水润滑作用。轴封处装有可更换的轴套，保护泵轴。

三、进口卧式多级管道泵工作原理
卧式多级泵为多级分段式，其吸入口位于进水段上，成水平方向，吐出口在出水段上垂直向上，其扬程可根据使用需要而增减水泵级数管道泵。水泵装配良好与否，对性能影响关系很大，尤其是各个叶轮的口出与导翼的进出中心，其中稍有偏差即将使水泵的流量减少，扬程降低效率差，故在检修后装配时务必注意。 WSDJ水泵的主要零件有：进水段、中段、出水段、叶轮、导翼挡板、出水段导翼、轴、密封环、平衝盘、轴套、尾盖及轴承体。 进水段、中段、导叶挡板、出水段导翼、出水段及尾盖均为锈铁制成，共同形成泵的工作室。 叶轮为优质锈铁制成，内有叶片，液体沿轴向单侧进入，由于叶轮前后受压不等，必然存在轴向力，此轴向力由平衝盘来承担，叶轮制造时经静平衡试验。 轴为优质炭素钢制成，中间装有叶轮，用键、轴套及轴套螺母固定在轴上。轴的一端装联轴器部件，与电 机直接连接。 密封环为锈铁制成，防止水泵高压水漏回进水部分，分别固定在进水段与中段之上，为易损件，磨损后可用备件更換。 平衡环为铸铁制成，固定在出水段上，它与平衡盘共同组成平衝装置。 平衡盘为耐磨锈铁制成，装在轴上，位于出水段与尾盖之间，平衡轴向力。 轴套为锈铁制成，位于填料室处，作固定叶轮和保护泵轴入用，为易损件，磨损后可用备件更換。 轴承是单列向心球轴承，采用钙基润滑脂润滑。填料起密封作用，防止空气进入和大量液体漏出，填料密封由进水段和尾盖上的填料室，填料压盖，填料环及填料等组成，少量高压水流入填料室中起水封作用。填料的松紧程度必须适当，不可太紧亦不可太松，以液体能一滴一滴的渗出为准。如果填料太紧，轴套容易发热，同时耗费功率。填料太松，由于液体流失要降低水泵的效率。
