Characteristics of rotating joint of crane tube

Date of release:2018-10-26 Author: Click:

The rotating joint of crane pipe is processed by precision CNC machine tool, which has large bearing capacity, flexible rotation, ideal sealing effect for liquid and gaseous medium, and can be safely and reliably used in normal temperature, low temperature, high temperature and corrosive medium. 

The main seal, secondary seal and dustproof seal effectively realize zero leakage。 

The rotating joint is designed in a variety of structural forms, including simple steel structure to internal heating, lined PTFE structure, single raceway, double raceway and triple raceway. 

The rotating joint is detachable and can be easily replaced without removing the whole arm when the sealing ring is replaced. 

The rotating joint structure with flanges on both sides makes maintenance and replacement easier and faster. 

The main sealing ring of crane tube rotating joint is composed of polytetrafluoroethylene filled with graphite and stainless steel tension spring card lined with special treatment. 

The sealing ring adopts polytetrafluoroethylene material, which has the characteristics of good wear resistance, good sealing effect, strong aging resistance and so on. The spring is lined with spring to increase the elasticity of the sealing ring. After the sealing surface has been worn for a long time, the spring can be compensated in a certain range. 

Secondary seal. 

Similar to the main seal structure, the opening direction is axial and has good compensation performance. 

Dustproof seal. 

The dustproof seal is similar to the secondary seal to prevent moisture and dust from entering the raceway。 

Basic parameters of crane tube rotating joint。 

Nominal caliber: DN50, DN80, DN100, DN125, DN150, DN200. 

To learn more about the crane pipe, pay attention to the crane tube manufacturer Lianyungang huade Petrochemical Co。, Ltd。
