简图二. LK型立式長軸深井泵结构简图(型式XD)

1、 LK型可抽式立式長軸深井泵为立式单级（多级）离心式或斜流式带导叶体结构。

2、 泵的結構型式有泵吐出口在安裝基礎之上和之下(型式代號分別爲S和X)、泵承受軸向力和電機承受軸向力(型式代號分別爲T和D)、外接潤滑水和泵自身潤滑等形式。

3、 泵安裝型式有濕坑式安裝或幹坑式安裝。

濕坑式安裝：泵下部浸沒在吸水池中。

幹坑式安裝：泵采用管道進水，泵吸入喇叭口與進水管道之間采用90°肘形進水彎管聯接。

4、 泵軸承爲橡膠導軸承或賽龍導軸承。

5、 泵口径在1000mm以下时，泵转子一般为不可抽形式；泵轴向水推力及转子重量一般由泵本体推力轴承承受，泵和电机之间采用弹性联接；泵吐出口位于安装面基础之上（型式代号为ST的结构形式）。如有要求，也可以由电机承受轴向水推力及转子重量；或其它结构形式的组合（型式代号为SD、XT、XD）;用户如有要求， 也可以设计成可抽式结构形式。泵口径在1000mm以上时，泵转子一般为可抽形式；泵轴向水推力及转子重量一般由电机推力轴承承受，泵和电机之间采用刚性联接；泵吐出口位于安装面基础之下（型式代号为XD）。如有要求，也可以由泵承受轴向水推力及转子重量；或其它结构形式的组合（型式代号为XT、SD、ST）。用户如有要求， 也可以设计成不可抽式结构形式。

6、 泵本體承受軸向水推力及轉子重量時，泵推力軸承采用稀油潤滑，推力軸承部件帶Pt100測溫元件測軸承溫度或壓力式溫度計測潤滑油溫度。

7、 泵軸向密封采用填料密封。

8、 在泵安裝基礎上可以進行葉輪與葉輪室（轉動部分與靜止部分）之間間隙的調整，操作方便。

9、 從吐出方向往泵看，電機接線盒與泵外接潤滑水接管位于左側。也可根據用戶要求，布置在其它方位。

Structure feature:

1.   Series LK pumps are of vertical single stage and/or multistage centrifugal or     mixed flow with diffuser types.

2.   The following structure types are available for the pump:the discharge opening above and/or under the mounting foundation(Type Code named S and X respectively);the axial thrust force born by the pump and/or by the motor(Type Code named T and D);lubricating water from outside and/or from the pump itself.

3.   The intake sump is of wet pit and/or dry pit types.

Wet pit type:lower part of the pump inundated in the intake sump.

Dry pit type:the water enters into the pump,the suction bellmouth is connected with the inlet  pipe of the pump by means of elbow bend pipe of 90⁰.

4.   Rubber guide bearings and /or the Thordon guide bearings are available for  bearings of the pump.

5.   Generally when the nozzle diameter of the pump is under 1000mm , non pull-out type is adopted for the rotor and the discharge opening is above the mounting foundation(Type Code named ST). In this case the axial thrust force and the weight of the rotor are usually born by thrust bearings of the pump itself and  flexible connection is adopted between the pump and the motor.The thrust force and the weight of the rotor can also be born by the motor if required,or other structure types such as SD,XT,XD are available .Rotor pull-out type can also be adopted if required by clients.

Generally when the discharge diameter of the pump is above 1000mm, pull-out type is adopted for the rotor and the discharge opening is under the mounting foundation(Type Code named XD).In this case the axial thrust force and the weight of the rotor are usually born by thrust bearings of the motor and rigid connection is adopted between the pump

and the motor. The axial thrust force and the weight of the rotor can also be born by

the pump if required,or other structure types such as XT,SD,ST are available .Rotor non pull-out type can also be adopted if required by clients.  

6.   When the axial thrust force and the weight of the rotor are born by pump itself,the thrust bearing of the pump is lubricated with dilute oil and is equipped with a temperature detector Pt100 to detect bearing temperature and a pressure type thermometer to detect the temperature of lubricating oil.

7.   The antielectrochemical corrosion appliance is adopted for the part of the pump contacting the liquid to ensure the service life of the pump when seawater is pumped.

8.   The packing seal is adopted for the axial seal of the pump.

9.   The clearance between the impeller and the impeller chamber,i.e.the rotating component and the static component,can be easily adjusted on the pump mounting foundation.
