Oil seal 919772 is a sealing element used for fire-resistant oil circulating pump F3-V10-1S6S-1C20, installed on the pump shaft. It has good sealing performance and wear resistance, and its main function is to form a seal between the pump shaft and pump casing, prevent liquid leakage, and prevent external substances from entering the pump interior.

However, oil seals are a vulnerable component, and when they fail, they can have a negative impact on the sealing performance, lubrication, cleanliness, and overall operational stability of the pump, which may lead to a decrease in pump performance, malfunction, and damage. Early detection and replacement of failed oil seals is an important measure for maintaining the normal operation of pumps.

The failure of oil seal 919772 may cause the following problems:

1. Leakage problem: The failure of the oil seal can cause liquid in the pump to leak to the rotating shaft of the pump. This can lead to a decrease in pump performance, reduce pump efficiency, and may even lead to complete pump failure.

2. Lubrication problem: After the oil seal fails, the seal between the pump shaft and pump casing is damaged, and lubricating oil may also leak. Lack of sufficient lubrication can increase friction and wear, which may lead to damage to the pump shaft and bearings, thereby affecting the normal operation of the pump.

3. External substances entering: After the oil seal fails, external dust, impurities, or liquids may enter the interior of the pump. These substances may cause damage or blockage of internal components of the pump, affecting its performance and lifespan.

4. Increased noise and vibration: Failure of oil seals may cause abnormal friction between the pump shaft and pump casing, increasing the noise and vibration levels of the pump. This not only affects the normal operation of the pump, but may also have adverse effects on surrounding equipment and systems.
