Catch Net Equipment Analysis (2025 Updated Edition)
I. Core Advantages of the Catch Net
High Ball Collection Rate: Utilizes grid plate分流 design or funnel structure, achieving a ball collection rate of over 95%, avoiding issues such as ball leakage and ball loss.
Structure Optimization: Streamline components (e.g., eliminate small meshes, adjusting valves), enhance mesh rigidity and flow efficiency, reduce water resistance (≤250mmH₂O).
‌Operation Reliability: The grid plate can switch to "backwash" mode, automatically clearing debris and reducing water resistance, with the electric actuator providing precise positioning.
Versatile: Customizable for pipe diameters from DN300 to DN1200, suitable for retrofitting old units and new projects.

III. Installation and Maintenance Precautions
Installation Specifications:

‌Location Requirement: To be installed on the outlet section of the condenser circulating water pipe, the lower flange elevation must be higher than the ball mill pump inlet elevation.‌
Drive Unit: Electric actuator requires pre-tensioned vibration prevention; after installation, test the flexibility of the screen change.
Straight pipe segment reserved: Length of straight pipe prior to import ≥ 1 times the diameter of the circulating water pipe (e.g., for DN800, a reserved straight pipe of 800mm is required)
Maintenance Points:

Regular inspections: Check for web plate deformation, soldering issues, and shaft movement flexibility quarterly, and promptly adjust or replace parts as necessary.
Backwash Operation: Switch to "Backwash" mode weekly to clean debris, monitor pressure difference (immediately address if > 250mmH₂O).
Catch Rate Monitoring: Test catch rate (≥95%) after commissioning; investigate screen plate alignment or rubber ball quality if not up to standard.
