Structural Design
The vacuum roller consists of two primary components:
Vacuum Chamber: Typically manufactured using tin bronze centrifugal casting. For polyester mesh applications, copper shells with glue coating or stainless steel roller shells are utilized to prevent corrosion. The roller shell features countersunk round holes and employs a cantilever structure design for convenient mesh replacement.
Roll Shell: Commonly utilizes single chamber cast iron construction, with double and three-chamber options available. Multi-chamber designs enable different vacuum degrees to optimize energy consumption. Sealing is achieved through airbag and friction strip systems with integrated width adjustment capability.
