Various types of oil seals: multiple choices for mechanical seals
Oil seals, as an important component of mechanical equipment, have many different types, each with unique design and application characteristics to meet the needs of different working conditions. This article will introduce several common oil seal types and their characteristics.
1. Single lip oil seal:
Single lip oil seal is one of the simplest types of oil seals. It has only one lip-shaped sealing lip, which is installed on the shaft to prevent lubricating oil leakage and block external contaminants from entering. Single lip oil seals are suitable for low-speed and low-pressure applications, such as household appliances and some industrial equipment.
2. Double lip oil seal:
Double lip oil seal is more complex than single lip oil seal, and it has two lip-shaped sealing lips. This design provides better sealing performance and can work at higher speeds and pressures. Double lip oil seals are suitable for many industrial applications, such as automotive engines, construction machinery, etc.
3. Skeleton oil seal:
Skeleton oil seal is also called mechanical seal, which consists of a metal skeleton and rubber or polyurethane sealing lips. This type of oil seal is suitable for high-speed and high-pressure applications and can provide excellent sealing performance in harsh working environments. Skeleton oil seals are commonly found in industrial equipment, automotive transmission systems, etc.
4. Bellows oil seal:
The bellows oil seal uses a corrugated metal tube as a sealing element, which has good elasticity and adaptability. It can maintain effective sealing when the shaft is relatively displaced or vibrated, and is suitable for applications that require a certain displacement compensation, such as diesel engines, generator sets, etc.
5. Liquid seal:
Liquid seal is a sealing method based on liquid filling, which forms a seal through the pressure of the liquid. It is suitable for environments with high temperature, high pressure and special media, such as chemical equipment, high-temperature smelting furnaces, etc.
6. Gas seal:
Gas seal is a way to achieve sealing by using the pressure of gas. It is suitable for high-speed rotating equipment, such as centrifuges, wind turbines, etc., and can maintain effective sealing effect when rotating at high speed.
7. Rotating shaft gas seal:
Rotating shaft gas seal is a special gas seal suitable for high-speed rotating shafts, such as turbine machinery. It prevents liquid leakage by maintaining a gas barrier between the shaft and the seal, with lower friction losses and heat dissipation.
