 Maintenance and upkeep of the sealing auxiliary system?

The sealing auxiliary system is an important part widely used in mechanical equipment to ensure the sealing of the equipment, avoid the influence of external media on the equipment, and prevent internal media leakage. Generally composed of sealing materials, sealing devices, sealing liquids, lubricants, etc., daily maintenance and upkeep have a significant impact on the stable operation and extended lifespan of equipment.

1、 Maintenance of sealing materials

Sealing materials are the parts of the sealing auxiliary system that are prone to wear, such as O-rings, oil seals, etc., and need to be checked and replaced in a timely manner during equipment operation. The precautions are as follows:

Regularly inspect the sealing components for wear, deformation, or aging, especially in high-temperature and high-pressure environments where they are susceptible to damage.

When replacing the seal, suitable materials should be selected and installed correctly. It is strictly prohibited to have air leakage, liquid leakage, oil leakage, and other situations.

When replacing seals, clean the sealing area and use lubricant to make it smoother, reduce wear, and enhance sealing performance.

2、 Maintenance of lubricants

Lubricant is an important material in sealing auxiliary systems, mainly used to reduce friction and extend the life of sealing rings. Therefore, lubricants also need to be regularly inspected and replaced, with the following precautions:

Regularly check the oil level, quality, and quantity of lubricating oil (grease) to ensure the normal operation of the system.

When replacing lubricating oil (grease), choose the appropriate variety and model, add oil according to equipment requirements, and pay attention to the quality and storage environment of the grease.

When lubricating, the position and quantity of oil (grease) should be determined according to the actual situation to avoid excessive or insufficient lubrication.

3、 Maintenance of sealing device

The sealing device is a key component in the sealing auxiliary system, mainly responsible for transmitting hydraulic or pneumatic power to the controlled components. The maintenance of the sealing device should pay attention to the following points:

Regularly check whether the pressure, flow rate, temperature and other parameters of the sealing device are normal, and whether there is any leakage phenomenon.

Regularly clean and lubricate the sealing device to prevent contaminants from entering the system and affecting its sealing performance.

When disassembling or replacing the sealing device, appropriate tools should be used to avoid damage to the sealing surface and pipelines.

4、 Maintenance of sealed liquid

Sealing fluid refers to the liquid in hydraulic and pneumatic systems, mainly responsible for transmitting pressure and preventing seals from drying and cracking. The maintenance of sealed liquids requires attention to the following points:

Regularly check the moisture, oxidation, pH and other indicators of the sealing liquid, replace them in a timely manner, and ensure the quality of the liquid.

When replacing the sealing liquid, a suitable type of liquid should be selected and replaced according to the equipment manual. It is strictly prohibited to mix different types of sealing liquids.

During operation, the sealing liquid should be regularly refilled or refilled to ensure the normal operation of the system.

In summary, the maintenance and upkeep of the sealing auxiliary system should take into account both internal and external factors. Regular inspections and maintenance should be carried out regularly, and damaged components should be replaced or repaired in a timely manner to increase the stability and lifespan of the equipment and ensure the safety and efficiency of the production environment.
