High temperature hot oil rotary joint, also known as heat transfer oil rotary joint, is a transitional sealing device that inputs high-temperature fluid medium from a static system to a dynamic rotating system. This type of joint is widely used in equipment for conveying high-temperature media in industries such as rubber, leather, textiles, and machinery. The following is a detailed analysis of high-temperature hot oil rotary joints:
High temperature hot oil rotary joints are mainly used to connect pipelines for high-temperature heat transfer oil and are key components on production lines. Its main function is to ensure stable and leak free transmission of high-temperature thermal oil during equipment rotation, thereby ensuring the continuous operation of the production line.
1) High temperature resistance: High temperature hot oil rotary joints can withstand high temperature environments and typically operate normally at temperatures up to 450 ℃.
2) Sealing performance: Advanced sealing technologies such as spherical sealing or balanced end face sealing are used to ensure good sealing performance even under high temperature and high pressure. Some high-end products are also designed with a structure to prevent impurities in the heat transfer oil from entering the interior of the shell, effectively extending its service life.
3) Structural stability: Through the design of dual oil-free bearing support, the stability and durability of the joint have been improved, and it can work well even in non concentric situations.
4) Easy to maintain: Some joints can adjust their sealing performance at any time during equipment operation, reducing economic losses caused by downtime maintenance.
The material selection of high-temperature hot oil rotary joints is crucial, usually requiring components such as shells, shafts, seals, etc. to have high temperature resistance and corrosion resistance. Common materials include stainless steel, alloy steel, ceramics, etc. These materials not only maintain stable physical properties in high-temperature environments, but also have good wear resistance and corrosion resistance.
High temperature hot oil rotary joints are widely used in equipment that requires high-temperature thermal oil heating or cooling, such as synthetic leather, PVC microfiber leather bonding equipment, plastic rolling machines, internal mixers, hydraulic equipment, coating machinery, papermaking machinery, packaging machinery, chemical equipment, rubber machinery, textile printing and dyeing equipment, glass production lines, etc.
1) Pre use inspection: Before use, the rotary joint should be visually inspected to ensure that the surface is free of defects such as damage, cracks, deformation, etc; Check whether the sealing surface, oil seal, O-ring and other components are intact; Ensure that the joints and pipeline interfaces are clean and free of foreign objects.
2) Standardized installation: Install according to the instructions or professional guidance to ensure a secure installation and good interface sealing.
3) Regular inspection and maintenance: Regularly check the sealing performance and wear of the rotary joint, and replace severely worn components in a timely manner; Regularly replace and replenish lubricating oil; Regularly check if fasteners are loose and tighten them in a timely manner.
4) Safe operation: When working on the rotary joint, attention should be paid to its operating status. If any abnormal phenomena (such as impact, abnormal noise, leakage, etc.) are found, the machine should be stopped immediately for inspection and handling.
In short, as a key component on the production line, the stability and reliability of the performance of high-temperature hot oil rotary joints are directly related to the continuous operation and production efficiency of the production line. Therefore, when selecting and using, full consideration should be given to its characteristics, materials, application areas, as well as usage and maintenance requirements.
