How to solve the oil leakage of the thermal oil rotary joint?

1、 Clean the heat transfer oil and rotary joint
Impurities in thermal oil are one of the main causes of oil leakage in rotary joints. Therefore, before solving the problem of oil leakage in the rotary joint, it is necessary to first clean the heat transfer oil and the rotary joint. The specific method is as follows:

1. Clean the heat transfer oil
Special heat transfer oil cleaning agents can be used to remove impurities and sediment from the heat transfer oil to ensure its quality. Meanwhile, the problem of oil leakage in rotary joints caused by excessive impurities in the heat transfer oil can also be solved by replacing it with a new one.
2. Clean the rotary joint
When cleaning the rotary joint, it is necessary to remove the rotary joint, spray cleaning agent on the rotary joint, and gently scrub it with a soft brush or cotton swab to clean up any debris and oil stains on the rotary joint. Attention, when cleaning the rotary joint, try to avoid using water or water-based cleaning agents as water can easily cause rusting or corrosion of the rotary joint.
2、 Replace the seal
Oil leakage from rotary joints may also be caused by aging or wear of seals. If oil leakage still occurs after cleaning, it is necessary to check whether the sealing components in the rotary joint need to be replaced. Generally speaking, the seals in rotary joints need to be replaced once a year to ensure performance.
To replace the seal in the rotary joint, it is necessary to first remove the rotary joint, then remove the old seal, install the new seal, and ensure that the seal is installed properly and without dead corners. When replacing seals, it is also possible to consider updating other accessories of the rotary joint, such as valves, flow meters, etc.
3、 Upgrade rotary joint
If cleaning the heat transfer oil and rotating joint, replacing seals, and other methods cannot solve the problem of oil leakage in the rotating joint, then upgrading the rotating joint can be considered. At present, there are some new types of rotary joints on the market that have better sealing performance and corrosion resistance than traditional rotary joints, and have a longer service life.
When upgrading the rotary joint, it is necessary to select a new type of rotary joint that meets the usage conditions and specifications, and adjust the position of the rotary joint according to the specific situation to ensure its correct installation and use.
In short, the solution to the oil leakage problem of the heat transfer oil rotary joint needs to be determined according to the actual situation. This can be solved by cleaning the heat transfer oil and rotary joints, replacing seals, upgrading rotary joints, and other methods. No matter which method is adopted, patient and meticulous operation is required to ensure the solution of the oil leakage problem of the rotary joint and maintain the normal operation of the system.
