If the oil temperature drops below 40°C or exceeds 90°C, the oil’s quality can deteriorate, leading to potential damage and reduced compressor life. When the oil temperature is too low (below 40°C), the oil becomes too viscous, causing increased friction within the compressor.
[pdf] The solution here is to check and clean the unidirectional valve, replacing it when necessary. Improper installation or blockage of the oil return pipeline will impede the normal return of the lubricating oil.
[pdf] Choosing the optimal oil for your screw compressor should consider various factors: Manufacturer specifications: Always consult the manufacturer's recommendations regarding viscosity and oil type. Operating conditions: Evaluate ambient temperature, duty cycles, and typical compressor loads.
