The principle of high-temperature heat transfer oil rotary joint mainly involves its structural design and working mechanism to ensure stable and reliable transmission of heat transfer oil in high-temperature and high-pressure environments. The following is a detailed analysis of its principle:
1）. Shell and sealing device:
The shell of high-temperature heat transfer oil rotary joints is usually made of high-temperature resistant materials, such as gray cast iron, ductile iron, or steel parts, to withstand stress and corrosion in high-temperature environments.
The sealing device is the core component of a rotary joint, including a stationary ring, a moving ring, and multiple springs and other components. The static ring slides and fits inside the tail cover of the shell, while the dynamic ring is connected to the inner end of the outer tube, achieving dynamic sealing connection through the compression force of the spring.
2）. Bearing support:
In order to improve the stability and load-bearing capacity of the joint, high-temperature thermal oil rotary joints are usually supported by dual oil-free bearings. This design not only maintains good working performance in different concentric situations, but also effectively reduces vibration and noise.
3）. Insulation and heat dissipation:
An insulation layer is installed inside the wall of the outer pipe to reduce heat transfer to components such as bearings and improve the overall temperature resistance of the joint.
There are multiple heat dissipation holes (usually waist shaped holes) on the housing between the two bearings, which can timely dissipate the heat transferred by the heat transfer oil and prevent bearing jamming or other faults caused by high temperature.
1）. Thermal oil transmission:
When the heat transfer oil enters the high-temperature heat transfer oil rotary joint from the static system, it will be transmitted through the gap between the outer and inner pipes. Due to the fact that the inner tube is inserted into the outer tube and can rotate inside the outer tube, the heat transfer oil can be continuously and stably transferred to the dynamic rotating system as the inner tube rotates.
2）. Sealing performance:
The sealing device plays a crucial role in the transmission process. The tight fit between the stationary and moving rings, as well as the compression force of the spring, ensures that the heat transfer oil will not leak out from the joint. Meanwhile, as the inner tube rotates and the pressure of the heat transfer oil changes, the sealing device can automatically adjust its sealing performance to adapt to different working conditions.
3）. Heat dissipation and thermal balance:
By designing the heat dissipation holes and insulation layer on the shell, the high-temperature heat transfer oil rotary joint can effectively dissipate the heat transferred by the heat transfer oil and maintain the internal thermal balance of the joint. This helps to extend the service life of the joint and improve its operational reliability.
1）. Strong high-temperature resistance: The use of high-temperature resistant materials and structural design enables the high-temperature heat transfer oil rotary joint to operate stably in high-temperature environments without failure.
2）. Good sealing performance: Advanced sealing technology and structural design ensure that the heat transfer oil will not leak during transmission.
3）. High stability: The dual oil-free bearing support and optimized structural design improve the overall stability and load-bearing capacity of the joint, reducing the generation of vibration and noise.
4）. Wide applicability: Widely used in equipment that needs to transport high-temperature media in industries such as rubber, leather, textile, and machinery.
In summary, the principle of high-temperature heat transfer oil rotary joints is to ensure stable and reliable transmission of heat transfer oil in high-temperature and high-pressure environments through reasonable structural design and advanced working mechanisms, and to meet various industrial needs.
