Screw compressor oil is essential for the compressor operation
An oil injected screw compressor requires oil for several key functions:
- Cooling
Helps dissipate heat generated during compression, preventing overheating. If the temperature of the compressor is too high, the element or all rotating parts would be excessively stressed and the service life would be shortened. - Lubrication
Prevents friction and wear on moving parts, especially the rotors. Metal to metal contact could lead to operational issues and early breakdown. - Sealing
Creates an effective seal between rotors and housing for efficient compression. - Cleaning and Filtration
Traps contaminants and impurities from incoming air to protect internal components. - Noise Reduction
Can reduce compressor noise by acting as a sound barrier.
The use of generic lubricants and irregular maintenance will have negative consequences to the lifetime, overall performance and energy efficiency of the machine.
When do I need to change my screw compressor oil?
To determine when your screw compressor oil needs replacing, there are several factors that need to be taken into account.
- Operating Hours
The number of hours the compressor has been running - Oil Type
Different oils have varying lifespans - Compressor Load
Higher loads may require more frequent oil changes. - Oil Filtration
Is the oil filtration system working effectively to maintain oil quality - Environmental Conditions:
Harsh operating environments like high temperature, dust and humidity may require more frequent oil changes.
