What oil does Roots blower use?

Roots blower, as a type of gas conveying equipment, is widely used in various industrial fields. Choosing the appropriate lubricating oil is crucial to ensure its normal operation and extend its service life. So, what oil does the Roots blower use? This article will explore in detail the role, selection criteria, and common types of lubricating oil.
1. The function of lubricating oil
Lubricating oil plays a crucial role in Roots blowers, mainly including the following aspects:
-* * Reduce Friction * *: Lubricating oil forms an oil film between the bearings, gears, and other moving parts of the Roots blower, reducing direct contact between metals and thus reducing friction and wear.
-Cooling and Cooling: Roots blower generates a large amount of heat during operation, and lubricating oil can absorb and take away some of the heat, playing a role in cooling and cooling.
-Sealing and Leak Prevention: Lubricating oil can fill the small gaps inside the Roots blower to prevent gas leakage and ensure the sealing of the equipment.
-Cleaning function: Lubricating oil can remove impurities and wear particles inside the Roots blower, keeping the equipment clean.
2. Selection criteria for lubricating oil
Choosing the appropriate lubricant requires consideration of the following factors:
-Viscosity: The viscosity of lubricating oil is an important indicator for selection. Excessive viscosity will increase frictional resistance and reduce efficiency; If the viscosity is too low, sufficient oil film cannot be formed, which increases wear. Therefore, the appropriate viscosity should be selected based on the working conditions of the Roots blower and the manufacturer's recommendations.
-Oxidation resistance: Roots blowers generate high temperatures during operation, and lubricating oil needs to have good oxidation resistance to prevent oil deterioration and carbon deposition.
-Wear resistance: Lubricating oil needs to have good wear resistance to reduce the wear of moving parts inside the Roots blower and extend the service life of the equipment.
-Rust prevention: The working environment of Roots blower may be humid, and lubricating oil needs to have good rust prevention to prevent internal components from rusting.
3. Common types of lubricating oil
According to the working conditions and requirements of Roots blowers, common types of lubricating oil include:
-Mineral oil: Mineral oil is a commonly used type of lubricating oil with good lubricity and antioxidant properties, suitable for Roots blowers under general working conditions.
-Synthetic oil: Synthetic oil has higher antioxidant and anti-wear properties, suitable for Roots blowers under high temperature and high load working conditions.
-Semi synthetic oil: Semi synthetic oil is a mixture of mineral oil and synthetic oil, which combines the advantages of both and is suitable for Roots blowers under moderate working conditions.
4. Practical application cases
In a large chemical plant, the mineral oil originally used had insufficient antioxidant properties, resulting in severe carbon deposition inside the Roots blower, which affected the normal operation of the equipment. After switching to synthetic oil, the stability of Roots blower operation was significantly improved, and the problem of internal carbon deposition was effectively solved. In addition, synthetic oil has a longer service life, reducing the frequency of lubricant replacement and lowering the operating costs of enterprises.
5. Conclusion
In summary, the selection of lubricating oil for Roots blowers is crucial. The appropriate type and viscosity of lubricating oil should be selected based on the working conditions of the equipment and the manufacturer's recommendations. Mineral oil, synthetic oil, and semi synthetic oil are common types of lubricating oils, each with its own advantages and disadvantages. By selecting and using lubricating oil reasonably, the service life of Roots blower can be effectively extended, ensuring its stable operation.
