Component Specifications

Definition
The bottom ring is a circular metal component positioned at the base of a filter bag cage in industrial filtration systems. It serves as the foundation that supports the vertical cage structure, ensures proper alignment of filter bags, and creates a sealed interface with the filter housing or support grid. This component maintains structural integrity during pressure differentials and prevents bypass of unfiltered media.
Working Principle
The bottom ring functions as a load-bearing base that distributes mechanical stress evenly across the filter bag cage structure. During operation, it maintains dimensional stability under varying pressure conditions (typically 0-150 psi), prevents lateral movement of filter bags, and ensures a tight seal against the filter housing through precision machining and gasket interfaces. Its circular design minimizes stress concentrations and allows for uniform media flow distribution.

Frequently Asked Questions

What is the primary function of a bottom ring in filter bag cages?

The bottom ring provides structural support, ensures proper sealing at the base, and maintains alignment of filter bags during operation.

Can bottom rings be customized for different filter sizes?

Yes, bottom rings are typically manufactured to match specific cage diameters and can be customized for material, thickness, and connection types.

How often should bottom rings be inspected?

Inspect during every filter bag change (typically every 3-12 months) for corrosion, deformation, or seal damage.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
