What does the regulating tube on the Delaval purifier direct into the rotating bowl?

The regulating tube on the Delaval purifier is designed to direct dirty oil into the rotating bowl. This is essential for the separation process, where contaminants and impurities are removed from the oil. As the dirty oil enters the rotating bowl, the centrifugal force generated by the rotation facilitates the separation of lighter contaminants from the heavier clean oil.

The purpose of this mechanism is to ensure that the incoming dirty oil is efficiently processed, allowing for the extraction of clean oil while leaving behind any unwanted solids or impurities. Thus, directing dirty oil into the rotating bowl is a crucial step in the purification process, enabling the system to function as intended.
