Working principle: The oil seal forms a sealing interface through the contact between the sealing lip and the rotating shaft. The seal lip is usually made of an elastic material, such as rubber or polyurethane. When the rotating shaft rotates, the sealing lip creates friction with the shaft surface, thus forming a sealing effect to prevent liquid or lubricating oil leakage.
Structure and composition: The oil seal usually consists of the following parts:
Housing: The housing is the fixed part of the oil seal, usually made of metal or plastic, that holds the shape of the oil seal and provides support.
Seal lip: The seal lip is a key part of the oil seal that contacts the rotating shaft and provides a sealing effect. The seal lip is usually made of an elastic material such as rubber or polyurethane, which is resistant to wear and oil.
Spring: The spring is usually installed behind the seal lip and is responsible for maintaining a close contact between the seal lip and the shaft to ensure the sealing effect.
Auxiliary parts: The oil seal may include auxiliary parts, such as a dust lip or grease reservoir, to prevent dust and contaminants from entering the sealed area, or to provide additional lubrication.
Applications: Oil seals are widely used in a variety of rotating equipment and machinery, including pump trucks, engines, transmissions, motors, etc. In pump trucks, oil seals are often used to prevent leakage of the hydraulic system, leakage of the lubricating oil system, and sealing of other rotating parts.
Selection and installation: The selection of the appropriate oil seal needs to consider a number of factors, such as the diameter of the shaft, rotation speed, working temperature, working medium and working environment. Different applications may require different types and specifications of oil seals. When installing the oil seal, ensure that the shaft surface is smooth and without scratches, and install the oil seal correctly to ensure a good sealing effect.
