Coolant Inlet Port: Temperature Range -20°C to 120°C

Component Specifications

Definition

The Coolant Inlet Port is a critical hydraulic component that serves as the entry point for coolant fluid into a cooling jacket system. It features standardized threaded or flanged connections, internal flow channels, and sealing surfaces to ensure leak-free operation under varying pressure and temperature conditions. This component regulates initial coolant distribution and maintains system pressure integrity.

Working Principle

Operates by providing a sealed interface between external coolant supply lines and the cooling jacket. The port's geometry controls flow velocity and minimizes turbulence while maintaining pressure through precision-machined internal surfaces and gasket/seal arrangements.

Materials

Typically manufactured from corrosion-resistant materials: Stainless Steel (AISI 304/316), Brass (C36000), or Aluminum Alloy (6061-T6). Sealing surfaces may include integrated rubber (EPDM/Nitrile) or polymer (PTFE) gaskets.
