Causes of leakage of mechanical rotating sealing ring

There are many types of chemical pumps in the chemical production process. Different types of chemical pumps will have different problems in actual use. According to the manufacturer of the rotating sealing ring, the common problem is the leakage of the mechanical rotating sealing ring. Some problems often occur in the work of the chemical pump. Among them, the main conditions that need to be repaired are the following.

There are many kinds of chemical pumps in the chemical production process, and different kinds of chemical pumps will have different problems in actual use.Rotating seal ringThe common problem is the leakage of the mechanical rotating sealing ring. Some problems often occur in the work of chemical pumps. Among them, the following situations need to be repaired.

Situation 1: Compared with other industrial production, the chemical production environment is very complex and faces many uncontrollable factors. In the actual production process, it will encounter harsh environments such as high temperature, high pressure, and high-strength corrosion, which will cause serious damage to the chemical pump. Therefore, It puts forward more stringent requirements for the manufacturing quality and use specifications of chemical pumps.

In actual work, the chemical pump pump will corrode according to the changes of the surrounding environmental factors at that time, which will also affect the vibration of the pump body, seriously affect the economic benefits of the chemical industry, and seriously cause explosions and fire accidents, causing casualties and poisoning, causing immeasurable losses to the enterprise, so it is necessary to repair the pump body.

Case 2: The chemical industry will experience a long production time in the production process, which makes the chemical pump stay in a complex working environment for a long time, resulting in damage to many details and many minor problems, such as component wear, pipe cracking, dynamic and static ring fracture, etc. The maintenance personnel of these problems should carry out strict and serious sealing inspection to ensure that all links can be strictly checked.

Case 3: Several auxiliary sealing rings are defective or improperly assembled, and the selected auxiliary sealing ring is not suitable for working conditions.

Case 4: The spring is broken, corroded, loosened, and coking due to insufficient preload or long-term operation. The suspended particles or crystals of the working medium are blocked in the spring gap for a long time, causing the spring to fail and the compensation sealing ring cannot float and leak.

Case 5: Due to the large deviation of the verticality between the sealing end face of the dynamic and static ring and the center line of the shaft, the sealing end face is not tightly combined, resulting in leakage.

Case 6: Due to the large axial movement of the shaft, the accessories related to the seal are not matched or of poor quality, which is easy to cause leakage.

The above is the sharing of the "mechanical rotating seal ring leakage reasons" content, we all understand it.
