结构特点
◆中间轴承采用金属滚动轴承，具有使用寿命长、运行稳定、振动小、噪音低等优点，并彻底消除了由
于导轴承长时间使用，磨损以后使机组产生振动的弊病。
◆采用结构化设计的思想，变传统的零件式安装为新型的部件式安装，即先将零件组装成中间部件，一
个中间部件为一节，安装时，一节一节的安装，提高了安装维修的工作效率，降低了检修时的工作强度。
◆中间联轴器采用弹性联轴器，从而节与节安装时，只需简单地将螺栓坚固即可，减小了安装维修时的
工作强度，且弹性联轴器能自动消除不同轴度，使轴与轴间不传递轴向力，只传递扭矩，提高了泵机组的运行稳定性。
◆轴封采用防沙盘加双端面机械密封的密封型式，与联接管形成严密的密封系统，使介质与金属有效隔
离，确保金属轴承的正常运行，彻底消除了传统结构型式的泵由于泥沙等颗粒杂质侵入转子部件而导致机组运行不稳定、磨损加剧、振动或使机组部件损坏等弊病。
◆该结构型式与传统的导轴承结构的长轴液下泵相比，具有以下优点：
☆ 便于运输：当泵长度超过3m时可拆卸运输，现场组装，以减少在运输过程中造成的弯曲现象。
☆ 便于安装维修：在使用过程中如某一节损坏，只需更换此节，不需全部拆卸维修，大大缩短了维修抢修时间，且维修方便。
☆ 无需外供冷却水：传统导轴承的泵运行时需外供或内供冷却水来冷却润滑中间滑动轴承，而该结构泵无需冷却水，节约了运行成本，而且还解决了长轴液下泵因阶段性缺冷却水造成中间滑大学班会
动轴承烧坏导致设备振动的难题。
☆ 机动性大：泵的长度可根据液下深度的不同，由不同数量的节插装组成，且节与节之间可互换。
☆ 运行成本低廉：因分节组合式安装，对安装起吊高度无特殊要求，可大大降低厂房高度，从而节约土建成本。
◆对于普通液下泵，输送带沉淀的污水（如粉煤灰水）时，由于沉淀的积累，容易造成泵进口堵塞（特
别是小口径泵），针对这一问题，我公司对该系列液下泵作了改进，使泵的下主轴向进口方向延伸，并伸出泵的进口，在靠近泵进口处加设一搅拌轮，与水泵叶轮同步工作。加设搅拌轮后具有如下优点： ☆ 该搅拌轮相当于在泵的进口处加了一个搅拌器，使泵进口处一定范围内含沉淀物的液体产生流动，阻止了沉淀物的沉积，有利于泵将杂质污水充分地排出。
☆ 有效的防止了由于泵长时间不用，造成沉淀物积累堵塞泵进口的问题，同时也防止了由于严重堵塞对叶轮、泵或电机的损坏。
☆ 由于杂质排出充分，延长了清理水池的周期，节约了用户运行及维护的成本。
☆ 结构合理，与普通液下泵相比成本增加较小。
CONSTRUCTION
◆ Intermediate bearing is metal roll bearing．It has the character of long life ud stably
running，little vibration and low noi etc．And we have completely solved the question due to the sliding bearing frayed that caus the t to vibrating during long-time ud． ◆ Adopting the idea of structural design and we change the conventional part asmbled into
new component asmbled。that is first as asmbling to an intermediate component．An intermediate component is a ction when asmbling just ction by ction it in creas The efficie
ncy of asmbling and re pairing，meanwhile it reduces The works of examining and repairing greatly．
◆ The intermediate coupling is adopted elasticity coupling When we asmble ction by ction，
we just only tie the bolts tightly，so it can reduce the works of asmbling and repairing very much and the elasticity coupling can adapt the angle of the shaft automatically It does not deliver the force of the shaft direction except torsion，so the stability of the pump t’s running is incread greatly．
◆ That the shaft is aled with the dust cover and two wear-resistant mechanical als forms
a hard al system with the link pipes which can make medium and metal well divided，insure
the normal running of the metal bearings and solve the conventional construction pump’s question such as the t’s instable running，terribly fraying vibration or leading the components of the t damaged，caud by the bed-load etc which invades into the rotor． ◆ Compared with the conventional long shaft wet pit pump with sliding bearing，it has such virtues
as：
☆ Easy Io be transported lf the length of the pump is over 3m，we can disasmble the pump to transport．When we arrive the destination，we will asmble them it is in order to avoid it being bent during transporting．
☆ Easy to be asmbled and repaired lf any ction is damaged in u we will only ex. change it Unnecessary to disasmble the whole．This can shorten the lime of repair it is also convenient to be maintained．
☆ Needs no cooling water The pump of the conventional sliding bearing construction needs cooling water to cool and lubricate the intermediate sliding bearing inside or out． side，when it runs Yet the pump of this con，struction needs no cooling water．so the cost is reduced And it also solved the problem that the equipment shook caud by the intermediate sliding bearing being damaged， when the long shaft wet pit pump lacked of cooling water for a moment．．
☆ Good flexibility The length of the pump can change with the depth under the liquid We just adapt the number of the ctions and it is exchangeable among the ctions． ☆ Low cost of transporting The pump is asmbled ction by ction．so it has no special request to the height of suspending，therefore this can reduce the height of suspending，therefore this can reduce the height of the workroom greatly and economize the cost of building．
◆ When common wet pit pump transfers the wage containing solid particles，it will be jammed
at the end of suction by depositive solid particles (especially the small suction pump) To solve this question，our company ameliorated this ries pumps The lower shaft extends lo the direction of the suction and*puts out of the pump suction end Near the suction end we add a mixing-wheel which can retate with the impeller in—pha it has such virtues as： ☆ it can make the liquid including deposit flowing in the area of the pump suction end avoid
deposit ttling，and be propitious to discharge wage and impurity fully.
☆ it can prevent the deposit from jamming the pump suction when the pump has not been ud
for a long lime and also prevent terribly jamming from damaging the impeller， pump and motor．
☆ The impurity is fully discharged，so the cycle to clean up the pool becomes long．Also
the cost of run and maintenance is economized．
☆ The construction is rational Compared with the common wet pit pump，cost increasing is
relatively small．
