What are the advantages of the sealing auxiliary system?

Sealing auxiliary systems play an important role in many industrial fields and equipment, and their advantages are as follows:

1、 Enhance sealing performance

Reduce the risk of leakage

The sealing auxiliary system can provide additional sealing protection for the main sealing components. For example, in mechanical seals, auxiliary systems can prevent leakage of the sealed medium by providing flushing or isolation fluid. Taking chemical reaction vessels as an example, toxic, harmful, or valuable chemicals may be processed inside the reactor. A sealed auxiliary system can effectively reduce the possibility of these substances leaking to the outside world, avoiding environmental pollution, personnel injury, and material loss.

For rotating equipment such as pumps and compressors, the sealing auxiliary system can compensate for changes in sealing clearance caused by wear, temperature changes, or pressure fluctuations in the main seals. This helps to maintain good sealing performance under various working conditions and reduce leakage. Like the oil pump in a refinery, the sealing auxiliary system can ensure that petroleum products do not leak into the surrounding environment under different oil temperature, oil pressure, and flow conditions.

Dealing with complex working conditions

In high temperature environments, the sealing auxiliary system can provide cooling medium to prevent seal damage due to overheating, while maintaining sealing performance. For example, in the blast furnace hot blast stove of the metallurgical industry, the hot air temperature is extremely high. The sealing auxiliary system reduces the temperature of the sealing part by circulating cooling medium to ensure that the hot air will not leak, maintain the high temperature and high pressure environment inside the furnace, and ensure the smooth progress of the ironmaking process.

In high vacuum application scenarios, the sealing assist system can help eliminate air and impurities in the sealed area, maintaining a vacuum environment. For example, in semiconductor manufacturing equipment, a high vacuum environment is crucial for chip manufacturing. The sealing auxiliary system continuously extracts gases that may leak in through equipment such as vacuum pumps to ensure that the vacuum degree meets production requirements.

2、 Extend equipment lifespan

Protect sealing components

The sealing auxiliary system can provide a good working environment for the seals. For example, by using a filtration system to remove solid particles from the sealing medium, these particles are prevented from entering the friction pair of the seal and the wear of the seal is reduced. In the paper industry, pulp contains a large amount of fibers and impurities. The filtration device of the sealing auxiliary system can effectively filter these substances, protect the seals of pumps and mixers, and extend their service life.

It can also provide lubricating medium and reduce the friction between seals. For some high-speed rotating equipment, such as turbomachinery, the lubricating fluid in the sealing auxiliary system can reduce the frictional heat of the seals, prevent seal damage due to dry friction, and thus extend the service life of the seals and the entire equipment.

Reduce equipment maintenance frequency

Due to the sealing assistance system helping to maintain the good condition of the seals, equipment failures and maintenance caused by sealing issues will be greatly reduced. For example, in the sludge pump of a sewage treatment plant, the sealing auxiliary system can effectively prevent corrosive substances and solid particles in the sludge from damaging the seals, extending the maintenance cycle of the pump from frequent months to a year or even longer, reducing equipment maintenance costs and downtime.

For some large and critical equipment, such as cooling water pumps for generator sets, reducing maintenance frequency can improve equipment availability. The sealing auxiliary system ensures that the equipment can operate stably for a long time by providing a stable sealing environment, reducing production interruptions caused by equipment failures.

3、 Improve device performance

Ensure stable operation

The sealing auxiliary system can ensure stable operation of the equipment under specified parameters such as pressure, temperature, and flow rate. Taking the chemical pipeline system as an example, the sealing auxiliary system can balance the pressure difference inside and outside the pipeline by adjusting the pressure inside the sealing chamber, prevent the medium from leaking at the pipeline connection, and ensure that the chemical fluid can be stably transported in the pipeline according to the design requirements, maintaining the stability of the entire chemical production process.

In hydraulic systems, the sealing auxiliary system can prevent hydraulic oil leakage and ensure pressure stability of the hydraulic system. This is very important for equipment that requires precise control, such as CNC machine tools and construction machinery, to ensure the accuracy and response speed of the equipment's actions.

Improve work efficiency

Good sealing effect can reduce energy loss. For example, in a steam turbine, a sealing assist system prevents steam leakage, improves steam utilization efficiency, and thus enhances the output power of the turbine. Similarly, in refrigeration equipment, the sealing auxiliary system can prevent refrigerant leakage, ensure the refrigeration efficiency of the refrigeration system, and reduce energy consumption.

The sealing auxiliary system can also improve the automation level of the equipment. For example, by integrating with the control system of the equipment, automatic monitoring and adjustment of sealing parameters can be achieved. When there is an abnormality in sealing pressure or temperature, the system can automatically take measures to adjust and improve the operating efficiency and safety of the equipment.
