Centrifugal Separator Integrated Outlet Tube Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing centrifugal separators for cleaning crankcase gases face challenges in achieving reliable sealing of the outlet tube, particularly in high-volume production, where hidden seals can be difficult to check and control, and manual assembly may damage O-ring seals.
Innovation Solution
The centrifugal separator design integrates the stationary insert and gas outlet tube as a single unit, eliminating the need for additional seals like O-rings, thereby enhancing sealing capacity and simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If O-ring seals are used to seal the outlet tube, then sealing function is improved, but manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The outlet tube is merged with the stationary insert to form a single integrated component. This eliminates the need for separate O-ring seals between these two parts, reducing assembly complexity while maintaining sealing function through the integrated design itself
2Reliability
If O-ring seals are used to seal the outlet tube, then sealing function is improved, but detection and quality control become difficult
Solution Approach 1:
By integrating the outlet tube and stationary insert into one component, the sealing function becomes inherent to the structure rather than dependent on hidden seals. This makes quality control and detection straightforward as there are no concealed seal elements to inspect
3Reliability
If manual assembly is used to install O-ring seals, then sealing function is improved, but production efficiency decreases and seal damage risk increases
Solution Approach 1:
The integrated outlet tube and stationary insert eliminate the need for manual seal installation. The single-component design allows for automated production processes, significantly improving productivity while eliminating the risk of manual damage to delicate seal elements

AI summary
The present invention provides a centrifugal separator (1) for cleaning gas containing contaminants. The centrifugal separator is comprising a stationary casing (2), enclosing a separation space (3) through which a gas flow is permitted, a gas inlet (20) extending through the stationary casing (2) and permitting supply of the gas to be cleaned, a rotating member (7) comprising a plurality of separation members (9) arranged in said separation space (3) and being arranged to rotate around an axis (X) of rotation. The separator (1) further comprises a gas outlet tube (28) arranged through the stationary casing (2) and configured to permit discharge of cleaned gas out from the stationary casing (2), a drainage outlet (29) arranged in the stationary casing (2) and configured to permit discharge of liquid contaminants that have been separated from the gas out from the stationary casing and a drive member (22) for rotating the rotating member (7). The centrifugal separator further comprises a stationary insert (30) arranged in the stationary casing (2) and configured for segregating cleaned gas and separated contaminants prior to the cleaned gas and separated contaminants exiting said stationary casing (2), and wherein said gas outlet tube (28) and said stationary insert (30) is formed as a single unit (50).
