Inlet Head: Flow_Rate_Capacity 50-500 GPM

Component Specifications

Definition

The Inlet Head is a critical hydraulic component in desander and desilter systems that receives incoming slurry or drilling fluid and directs it tangentially into the cyclone separation chamber. It's engineered to create optimal vortex flow patterns for efficient solid particle separation through centrifugal force. This component ensures proper fluid distribution, minimizes turbulence, and maintains consistent pressure for maximum separation efficiency.

Working Principle

The Inlet Head operates on fluid dynamics principles where incoming slurry enters tangentially through specially designed ports, creating a controlled vortex flow. This tangential entry generates centrifugal forces that separate heavier solid particles from the fluid stream. The design ensures laminar flow transition into the cyclone body, preventing premature turbulence that could reduce separation efficiency.

Materials

High-chrome cast iron (ASTM A532 Class III Type A), Abrasion-resistant steel (AR400/AR500), Duplex stainless steel (UNS S31803/S32205), Tungsten carbide-lined for extreme abrasion resistance
