The rotary joint used in rubber machinery is an indispensable key component in rubber machinery, and its design structure and function are crucial to ensuring the smooth progress of rubber processing. The following is a detailed analysis of rotary joints used in rubber machinery:
Rotary union, also known as rotary joint, is a type of pipeline connection device that can achieve relative rotation of connected pipelines and is used to transport various media such as gas, liquid, oil, etc. In rubber machinery, rotary joints are mainly used as sealing devices for connecting and discharging liquids (such as water, oil, coolant, etc.) from the pipeline side into rotating or reciprocating equipment. It ensures the stability and sealing of the medium during transmission, avoiding leakage and contamination.
There are various types of rotary joints used in rubber machinery, including hydraulic rotary joints, high-pressure rotary joints, multi-path rotary joints, high-speed rotary joints, etc. These rotary joints are designed according to specific application scenarios and requirements to meet different working conditions.
Structurally, a rotary joint typically consists of a rotating part, a stationary part, and a sealing part. The rotating part is connected to the rotating components of the mechanical equipment, while the stationary part is connected to the fixed pipeline. The sealing part adopts various sealing materials and technologies, such as flat sealing, spherical sealing, and line sealing, to ensure that the medium will not leak during transmission.
Rubber machinery rotary joints are widely used in various equipment for rubber processing, such as calendering machines, screw extruders, mixing mixers, kneading machines, rotary and laminating machines, drum type automatic vulcanizing machines for rubber, and flat vulcanizing machines. In these devices, rotary joints play an important role in connecting and transmitting media, ensuring the normal operation of the equipment and the smooth progress of the processing.
1）. Ensure sealing performance: During use, the sealing performance of the rotary joint should be regularly checked to prevent medium leakage. If any leakage is found, the seal should be replaced or repaired in a timely manner.
2）. Avoid impact and falling: During transportation and storage, the rotating joint should be protected from impact and falling to prevent damage to the interface and internal components.
3）. Standardized installation and replacement: The installation and replacement of rotary joints should be strictly carried out in accordance with the specifications to avoid problems such as water leakage and looseness caused by improper installation.
4）. Regular inspection and maintenance: Regularly inspect and maintain rotating joints, such as cleaning, lubrication, etc., to extend their service life and ensure their normal operation.
In the rubber processing industry, the selection and use of rotary joints have a significant impact on the normal operation and processing quality of equipment. For example, in some complex rubber processing processes, it is necessary to use high-temperature and high-pressure resistant rotary joints to ensure stable transmission of the medium. At the same time, for equipment that operates for a long time, aging rotary joints should be replaced regularly to avoid leaks and malfunctions.
In summary, the rotary joint used in rubber machinery is an indispensable key component in the rubber processing process. Its design structure, functional characteristics, application scenarios, and usage precautions all need to be given sufficient attention and focus. Reasonable selection and standardized use of rotary joints can ensure the smooth progress of rubber processing and improve the service life and processing quality of equipment.
