Travelers Plans How to Travelers Plans in The World
Traveling water screens are an essential component of water intake systems for power plants, water treatment plants, and other industrial facilities that require large amounts of water for their operations. These screens prevent debris and aquatic organisms from entering the water intake system and causing damage to the pumps, turbines, and other equipment. Traveling water screens manufacturers design and produce these screens with different specifications and features to suit the needs of their clients. In this article, we will explore more about traveling water screens manufacturers and their products.
What are Traveling Water Screens?
Traveling water screens are mechanical devices that filter water in large intake structures. They consist of a series of parallel bars or wires, spaced apart to allow water to flow through but prevent debris, fish, and other organisms from entering the intake. The screens are typically mounted on a traveling carriage that moves along the intake channel, continuously removing debris and preventing clogging. The debris is collected in a hopper or conveyor, where it can be disposed of or recycled.
Types of Traveling Water Screens
There are several types of traveling water screens available from different manufacturers. Some of the common types include:
- Cable-Driven Screens: These screens are driven by a cable system that moves the screen along the intake channel. They are suitable for use in deep intakes and can handle high flow rates.
- Hydraulic Screens: These screens are driven by hydraulic systems that use water pressure to move the screen. They are suitable for use in shallow intakes and can handle low to medium flow rates.
- Mechanical Screens: These screens are driven by mechanical systems that use gears, chains, or belts to move the screen. They are suitable for use in medium to deep intakes and can handle high flow rates.
Features of Traveling Water Screens
Traveling water screens manufacturers typically offer screens with different features and options to meet the specific requirements of their clients. Some of the common features include:
- Screen Material: The screens can be made of various materials such as stainless steel, fiberglass, and aluminum. The choice of material depends on the application and the environment.
- Screen Size: The size of the screen depends on the flow rate and the size of the intake. Traveling water screens manufacturers offer screens in different sizes to match the specific requirements of their clients.
- Screen Openings: The spacing between the bars or wires on the screen determines the size of the debris that can be removed. Traveling water screens manufacturers offer screens with different opening sizes to match the specific requirements of their clients.
- Screen Cleaning System: The screen cleaning system removes the debris from the screen surface and disposes of it. Traveling water screens manufacturers offer screens with different cleaning systems such as spray nozzles, brushes, and air jets.
- Control System: The control system operates the screen and monitors its performance. Traveling water screens manufacturers offer screens with different control systems such as PLCs and SCADA systems.
