Component Specifications

Definition
A specialized cooling system integrated into paper machine reel spools that circulates temperature-controlled fluid through internal channels within the shaft to maintain optimal operating temperatures, preventing thermal deformation that could compromise paper roll uniformity and winding precision during high-speed production.
Working Principle
Utilizes forced circulation of cooling fluid (typically water or glycol mixture) through internal axial channels within the shaft structure. Heat transfer occurs via conduction from the shaft material to the circulating fluid, with temperature regulation controlled by external heat exchangers and flow control systems to maintain shaft within specified thermal operating range.
Materials
Stainless steel (AISI 316L) shaft body with corrosion-resistant internal tubing, food-grade polymer seals, copper-nickel alloy heat transfer surfaces where applicable.
Technical Parameters
  • Flow Rate 40-80 L/min
  • Pressure Rating 6-10 bar
  • Cooling Capacity 15-25 kW
  • Temperature Range 10-40°C
  • Shaft Diameter Compatibility 150-400 mm
Standards
ISO 12100, ISO 13849-1, DIN 8601
