Abstract
A centrifugal separator bowl, having a vertical rotational axis, the separator bowl defining a separation space, and including an upper bowl section having a first threading, the first threading having a first inner diameter and a first outer diameter and defining an upper surface, and a lower bowl section having a second threading corresponding to the first threading of the upper bowl section, the second threading having a second outer diameter and a second inner diameter and defining a lower surface. The upper surface of the first threading of the upper bowl section and the lower surface of the second threading of the lower bowl section form a screw connection. The upper surface of the first threading is inclined upward with a first angle from the first inner diameter to the first outer diameter and the lower surface of the second threading is inclined downward with a second angle from the second outer diameter to the second inner diameter relative to a horizontal plane extending perpendicular to the vertical rotation axis.
