- Công suất mạnh mẽ Máy nén khí diesel thường có công suất lớn hơn so với các mẫu máy nén khí chạy điện, cho phép nén khí với lưu lượng lớn và áp suất cao, đáp ứng nhu cầu cho những công việc đòi hỏi khắt khe.
Choosing Quality Auto Parts Oil Seals:
- Nitrile oil seals offer several advantages over other types of seals. Their excellent resistance to hydrocarbons, such as gasoline, diesel, and lubricating oils, makes them ideal for automotive engines and transmission systems. Moreover, they exhibit good compression set resistance, ensuring a long-lasting seal even under constant pressure. Their ability to maintain their integrity in both cold and hot conditions further enhances their versatility.
- fluoro-rubber oil seals are used in drilling machinery, refining equipment, and natural gas desulfurization
- The significance of the blue valve cover gasket becomes evident when one considers the potential consequences of a faulty seal. Oil leaks can not only reduce the amount of lubricant available for the engine's moving parts but also lead to a buildup of oil on the engine's exterior. This can be detrimental in several ways; it may cause the engine to overheat, leading to damage or even failure. Furthermore, an oil-soaked engine surface is a fire hazard, especially under the hood where temperatures can reach extreme levels.


3. Seal types and numbering system
3. TEMPERATURE: Similar to the pressure level, you need to know what temperature your machinery can operate at. You need to choose a seal that can withstand the heat or cold. PTFE have the widest rang of temperature, making them a safe option when you are uncertain of the range.
This represents a new generation of oil seals.


Most effective sealing is obtained with optimum shaft surface finishes. The sealing efficiency is affected by the direction of the finish tool marks and the spiral lead. Best sealing results are obtained with polished or ground shafts with concentric (no spiral lead) finish marks. If you must use shafts with spiral finish leads, they should lead toward the fluid when the shaft rotates.

The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s.
