[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example

[0017] See also Figure 1 The utility model provides the following technical solutions: a heat transfer oil rotary joint, including a shell 2, a sealing gasket 10 is arranged on the lower rear end surface of the shell 2, a guide ring 9 is arranged behind the sealing gasket 10, and a compensating locking nut 8 is arranged above the guide ring 9.

[0018] In this embodiment,

[0019] 1. Function and implementation of guide ring 9

[0020] 1. Function of guide ring 9

[0021] Guiding and supporting: The guide ring 9 mainly plays the role of guiding and supporting. It can prevent the rotary joint from deviating or shaking during the rotation process, thereby improving the stability and concentricity of the rotary joint.

[0022] Reduce friction and wear: The guide ring 9 can also reduce the direct contact and friction between the rotary joint and other parts of the equipment, thereby extending the service life of the rotary joint.

[0023] 2. Implementation of guide ring 9

[0024] Material selection: The guide ring 9 is usually made of wear-resistant and high-temperature resistant materials, such as PTFE polytetrafluoroethylene, POM polyoxymethylene, PA nylon, etc. These materials have good mechanical properties and chemical stability, and can maintain stable performance under high temperature and high pressure environments.

[0025] Structural design: The structural design of the guide ring 9 needs to consider its matching accuracy with the rotary joint and the installation method to ensure that it can fit the rotary joint tightly and play an effective guiding and supporting role.

[0026] 2. Function and implementation of compensatory locking nut 8 device

[0027] 1. The function of compensatory locking nut 8 device

[0028] Locking and compensation: The device fixes the rotary joint to the equipment through the locking nut, and can compensate for the position deviation of the rotary joint caused by factors such as equipment vibration and temperature change to a certain extent, thereby maintaining the stability and concentricity of the rotary joint.

[0029] Adjustment and adaptation: By adjusting the tightness of the locking nut, the position of the swivel joint can be fine-tuned to meet the usage requirements under different working conditions.

[0030] 2. Implementation of compensatory locking nut 8 device

[0031] Structural design: The device usually includes a locking nut, an adjusting bolt and other components. The tightness of the locking nut is changed by rotating the adjusting bolt, thereby achieving adjustment and compensation of the position of the rotary joint.

[0032] Installation and debugging: During the installation process, it is necessary to ensure that the matching accuracy and installation position of the locking nut and the rotary joint are accurate, and carry out necessary debugging and testing to ensure that it can work normally and achieve the expected effect.

[0033] 3. The implementation effect of the overall solution

[0034] By adding the guide ring 9 and the compensating locking nut 8, the stability and concentricity of the thermal oil rotary joint during rotation are greatly improved. This can not only reduce equipment failures and downtime caused by the deviation or shaking of the rotary joint, but also improve the overall operating efficiency and production benefits of the equipment. At the same time, this solution also extends the service life of the rotary joint and reduces the maintenance cost and replacement frequency of the equipment.

[0035] In order to improve the stability of the joint, the design uses double oil-free bearing support, which can maintain good working condition even if there is eccentricity during the operation of the equipment. This design helps to resolve the deflection and vibration from the rotating body, thereby improving service life and reliability.

[0036] The imported antimony - immersed ring and the unique anti - impurity and secondary - sealing design further enhance the performance of the joint. These design features help reduce maintenance requirements, extend the sealing life, reduce the number of shutdowns, thereby reducing maintenance costs and increasing production efficiency.

[0037] To prevent impurities in the heat - conducting oil from entering the interior of the housing 2, the product is designed with a structure to prevent impurity entry, effectively preventing the wear of the sealing surface by impurities, greatly extending the service life, and making it an ideal special rotary joint for high - temperature heat - conducting oil.
