Analysis of the causes of damage to floating oil seals
Floating oil seals are a common sealing device that is widely used in various mechanical equipment, such as pumps, compressors and engines. However, due to various reasons, oil seals are sometimes damaged, resulting in equipment not working properly. The following is to share with you the common causes of oil seal damage.
1、Harsh conditions of the use environment
For example, the use of oil seals in high temperature, high humidity, corrosive gas or liquid environments can lead to aging, deformation or corrosion of their materials, thus reducing their sealing performance. In addition, if the equipment is used in a dusty environment, the dust will enter the sealing gap of the oil seal and wear the sealing surface, resulting in leakage.
2、Incorrect installation and maintenance
If the floating oil seal is not installed correctly during installation, for example, it is not installed on the shaft correctly or the sealing gap is not adjusted correctly, it will lead to excessive pressure or friction on the oil seal, which will be damaged. In addition, if the aging or worn oil seal is not regularly inspected and replaced during use, it will also lead to its damage.
3、Vibration and impact of equipment operation
During the operation of the equipment, due to unbalance, looseness or incorrect installation, vibration and shock will be generated, these vibration and shock will produce additional pressure and friction on the oil seal, which will lead to its damage. In addition, if the equipment in the process of starting and stopping frequent impact, will also cause damage to the oil seal.
4、Inappropriate use
For example, if the equipment exceeds the rated speed or working pressure of the oil seal during operation, it will cause the oil seal to be subjected to excessive pressure and friction, thus causing damage. In addition, if the equipment in the process of starting and stopping frequent impact, will also cause damage to it.
To summarize, the main reasons for the floating oil seal being damaged include the harsh conditions of the environment in which it is used, incorrect installation and maintenance, vibration and shock during the operation of the equipment, and improper use. In order to prolong its service life, we should choose suitable oil seal materials, provide a good use environment, correctly install and maintain the oil seal, reduce the vibration and shock of the equipment, and comply with the use specifications of the equipment.
