LC vertical Long-shaft Pump

Water companies, sewage treatment plants, power plants, iron and steel plants, mines and other industrial and mining enterprises, as well as municipal water supply and drainage, farmland irrigation, flood control and drainage projects.

STRUCTURE

Overview of major parts materials

LC type vertical long shaft pump suction inlet straight down, outlet level, vacuum free start, single base installation, pump and motor direct connection, the base covers a small area; Looking down from the motor end, the pump rotor components rotate counterclockwise, the main features are:

1. with hydraulic design software optimization design, excellent performance, and fully consider the impeller, guide vane body abrasion resistance, so that the impeller, guide vane and other parts of the life is greatly improved; Products run smoothly, safe and reliable, high efficiency and energy saving.

2. LC type energy-saving vertical long-shaft pump inlet is equipped with a filter screen, the opening size is appropriate, not only effectively prevent large particles of impurities into the pump to damage the pump, but also greatly reduce the import loss, improve the efficiency of the pump.

3. The impeller of LC type energy-saving vertical long-axis pump uses a balance hole to balance the axial force, and the front and rear cover plates of the impeller are equipped with replaceable sealing rings to protect the impeller and guide vane body.

​4. LC type energy-saving vertical long shaft pump rotor components include impeller, blade shaft, intermediate shaft, upper shaft, coupling, adjusting nut and other parts.

5. LC type energy-saving vertical long shaft pump intermediate shaft, lifting pipe and protection pipe are multi-section, and shaft is connected by screw coupling or sleeve coupling; The number of lifting pipes can be increased or decreased according to user needs to adapt to different liquid depths. The impeller and guide vane body can be single stage or multiple stage to adapt to different head requirements.

6. The length of a single shaft is reasonable and the stiffness is sufficient.

7. LC type vertical long shaft pump pipe is connected by flange, and there is a guide bearing body between the adjacent 2 sections of the pipe. The guide bearing body and guide vane body are equipped with guide bearings, and the guide bearings are made of polytetrafluoroethylene or Cyron or nitrile rubber. The protection pipe is used to protect the shaft and guide bearing. When water is transported, the protection pipe can be canceled, and the guide bearing does not need external cooling and lubricating water. When transporting sewage, the protection pipe must be installed, and the guide bearing must be externally cooled and lubricated water (the pump has a self-enclosed sealing system, and the self-enclosed sealing system can prevent sewage from entering the guide bearing after the pump is shut down).

8. The residual axial force of LC type vertical long-shaft pump and the weight of rotor components can be borne by the thrust bearing in the motor support or the motor with thrust bearing. Thrust bearings are lubricated by grease (also known as dry oil lubrication) or lubricating oil (also known as thin oil lubrication).

9. the shaft seal of LC type vertical long shaft pump is packing seal, and the shaft seal and guide bearing are equipped with a replaceable sleeve to protect the shaft. The axial position of the impeller is conveniently adjusted by the upper end of the thrust bearing component or the adjustment nut in the pump coupling.

10. LC type vertical long shaft pump outlet diameter φ100 and φ150 vertical long shaft pump is only used to transport normal temperature water, without protection pipe, guide bearings do not need external lubrication water lubrication; If the user needs φ100 and φ150 caliber vertical long shaft pump with protective pipe, the company can provide another technical solution.
