LK型立式长轴泵布局简图(型式ST)

简图二. LK型立式长轴泵布局简图(型式XD)

简图1. LK型立式长轴泵布局简图(型式XD)

1、 LK型可抽式立式长轴泵为立式单级(多级)离心式或斜流式带导叶体布局。

2、 泵的布局型式有泵吐出口在装置根本之上和之下(型式代号别离为S和X)、泵蒙受轴向力和机电蒙受轴向力(型式代号别离为T和D)、外接光滑水和泵本身光滑等情势。

3、 泵装置型式有湿坑式装置或干坑式装置。

湿坑式装置:泵下部淹没在吸池塘中。

干坑式装置:泵接纳管道进水,泵吸入喇叭口与进水管道之间接纳90°肘形进水弯管连接。

4、 泵轴承为橡胶导轴承或赛龙导轴承。

5、 泵口径在1000mm以下时,泵转子普通为不可抽情势;泵轴向水推力及转子分量普通由泵本体推力轴承蒙受,泵和机电之间接纳弹性连接;泵吐出口位于装置面根本之上(型式代号为ST的布局情势)。若有请求,也能够由机电蒙受轴向水推力及转子分量;或别的布局情势的组合(型式代号为SD、XT、XD);用户若有请求, 也能够设想成可抽式布局情势。泵口径在1000mm以上时,泵转子普通为可抽情势;泵轴向水推力及转子分量普通由机电推力轴承蒙受,泵和机电之间接纳刚性连接;泵吐出口位于装置面根本之下(型式代号为XD)。若有请求,也能够由泵蒙受轴向水推力及转子分量;或别的布局情势的组合(型式代号为XT、SD、ST)。用户若有请求, 也能够设想成不可抽式布局情势。

6、 泵本体蒙受轴向水推力及转子分量时,泵推力轴承接纳稀油光滑,推力轴承部件带Pt100测温元件测轴承温度或压力式温度计测光滑油温度。

7、 泵轴向密封接纳填料密封。

8、 在泵装置根本上能够停止叶轮与叶轮室(动弹局部与运动局部)之间空隙的调剂,操纵便利。

Structure feature:

1.   Series LK ,LB 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.
