Stable Operation SL-Type Water Intake Screen Precise Screening Easy Maintenance
Brief Description
This SL-type water intake screen is renowned for its stable operation, effectively reducing vibration and noise, ensuring a quiet and safe production environment. It provides precise screening, intercepting impurities of varying particle sizes to meet diverse operating conditions. Furthermore, its design emphasizes ease of maintenance, allowing for quick disassembly and cleaning, significantly reducing downtime. Suitable for pre-treatment of industrial water, such as circulating water systems and cooling tower makeup water.
Product Overview
Built to perform in the harshest operating conditions, the SL‑Type Water Intake Screen delivers heavy‑duty, mechanical raking performance for high‑volume water intake systems. Engineered to intercept and remove large, stubborn debris efficiently, it acts as a vital frontline barrier, safeguarding pumps, turbines, and key downstream equipment from potential harm caused by logs, vegetation, plastics, and other large solid contaminants.
Working Principle
*Interception: As water passes through the fixed bar screen, large debris is captured and retained on the upstream side.
*Lifting: Debris collected on the screen bars is continuously lifted by a set of rakes mounted on an endless chain system.
*Discharge: Upon reaching the upper end of the unit, rakes automatically release the debris, which drops by gravity into a collection hopper or conveyor for removal.
*Sealed Design: A supplementary bottom screen blocks bypass flow and debris, eliminating leakage and maintaining high overall screening efficiency.

Key Design & Performance Features
*Built-In Drive Motor: Features a fully enclosed motor within the main frame, offering superior outdoor protection. This design is ideal for exposed locations like hydropower stations and large pumping stations, ensuring reliability in harsh weather.
*Exceptional Debris Handling: Specifically engineered to capture and remove large, bulky objects such as whole bamboo trunks, tree branches, and industrial waste that would clog or damage ordinary screens.
*Uninterrupted Operation: Capable of continuous, 24/7 operation during periods of heavy debris influx, guaranteeing constant protection for your vital assets without interruption.
Applications
*Major stormwater management and flood mitigation pumping facilities
*Raw water withdrawal points from rivers, lakes and water reservoirs
*Forebay structures of hydropower stations and large-scale water conservancy projects
*Industrial water treatment facilities needing elimination of large floating debris
