Component Specifications

Definition
The overflow discharge is a critical component in desander and desilter systems that facilitates the continuous removal of separated solid particles from hydrocyclone overflow streams. It consists of discharge ports, flow control mechanisms, and collection interfaces designed to handle abrasive slurry mixtures while maintaining system pressure balance and preventing re-entrainment of solids.
Working Principle
Utilizes centrifugal separation principles where heavier solid particles migrate to the hydrocyclone walls and exit through the underflow, while the overflow stream containing finer particles exits through the discharge ports. The component maintains controlled flow rates and pressure differentials to optimize separation efficiency.
Materials
Abrasion-resistant materials including polyurethane, ceramic-lined steel, hardened stainless steel (AISI 316L), or tungsten carbide for high-wear applications. Gaskets typically use EPDM or Viton for chemical resistance.
Technical Parameters
  • Flow Capacity 10-500 m³/h
  • Port Diameter 50-200 mm
  • Connection Type Flanged (ANSI/ASME B16.5) or threaded
  • Pressure Rating 0.5-2.0 MPa
  • Temperature Range -20°C to 120°C
Standards
ISO 9905, DIN 24251, API RP 13C

Frequently Asked Questions

What is the primary function of the overflow discharge in desander systems?

The overflow discharge removes the cleaned liquid stream containing fine particles from hydrocyclones while maintaining system pressure balance and preventing solids re-entrainment.

How often should overflow discharge components be inspected?

Regular inspection every 500 operating hours is recommended, with wear checks on discharge ports and gasket integrity assessments to prevent leakage and efficiency loss.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
