Lubrication Guide for Roots Blowers: Choosing the Right Lubricant to Make the Equipment More Durable
As an important equipment in the industrial field, the lubrication problem of Roots blower often causes headaches for operators - choosing the wrong oil may lead to equipment overheating, increased noise, and even premature scrapping. Today, we will discuss from multiple perspectives how to choose the appropriate lubricating oil for Roots blowers to ensure smoother operation of your equipment!
Why is lubrication so important?
The Roots blower relies on two interlocked rotors to operate, and high-speed rotation generates a large amount of frictional heat. Good lubrication performance:
1. Reduce direct contact wear between metal components
2. Help dissipate heat and prevent overheating and deformation
3. Form a protective film to prevent rusting
4. Reduce operating noise
Common lubrication pain points
-Inappropriate oil viscosity leads to insufficient lubrication or excessive resistance
-Poor antioxidant performance, rapid deterioration of oil products
-Oil film ruptures at high temperatures, losing its protective function
-Mixing different brands of oil produces chemical reactions
Lubricant selection criteria
1. Type of base oil
-Mineral oil: Economical and suitable for normal temperature conditions (-10 ℃~60 ℃)
-* * Semi synthetic oil * *: Balancing performance and price, suitable for moderate loads
-* * Fully synthetic oil * *: Good high-temperature stability, recommended for heavy-duty or high-temperature environments
2 viscosity grades (using ISO standards as an example)
-Normal temperature environment: ISO VG 68 or 100
-High temperature environment (>60 ℃): ISO VG 150 or 220
-Cold regions: ISO VG 32 or 46
3 Special additives
High quality lubricating oil should include:
Antioxidants extend oil change intervals
Extreme pressure additives protect heavy-duty areas
Rust and anti-corrosion components
Usage suggestions
1. Oil change steps
1. After shutdown, discharge the old oil while it is still hot
2. Rinse the oil tank with cleaning oil
3. Add new oil to the centerline of the oil gauge
4. Check the oil level after running for 30 minutes
2 Daily maintenance
-Check the oil level and quality every month
-Change the oil after the first 200 hours of operation
-Afterwards, replace it every 2000-4000 hours or every six months
-The oil change cycle should be shortened under working conditions
Expert Tips
-Do not mix different brands of oil products
-Store oil products to avoid moisture and high temperatures
-Abnormal noise during operation is often an early signal of lubrication problems
-Keep the respirator unobstructed to prevent moisture from entering
Remember, the right lubricant is like the "blood" of a Roots blower, choosing the right one can extend the lifespan of the equipment by more than 30 years! When you are unsure, you may refer to the equipment manual or consult the lubricant supplier, who usually provides professional advice based on your specific working conditions.
