Customizable Wedge wire intake screen for Your Needs

some description about product

Wedge wire intake screen is a specialized filtration device commonly used in various industries to filter and remove solid particles from liquids. It is designed with a unique structure consisting of wedge-shaped wires and support rods, providing excellent filtration capabilities and high strength.

Wedge wire design allows for precise filtration by creating V-shaped openings between the wires. These V-shaped slots are carefully sized and positioned to effectively capture and retain particles while allowing the filtered liquid to pass through. The shape of the slots also prevents clogging and ensures a continuous flow of liquid.

One of the key advantages of wedge wire intake screens is their exceptional durability and resistance to harsh operating conditions. They are typically made from high-quality stainless steel, which provides excellent corrosion resistance, mechanical strength, and thermal stability. This makes them suitable for use in challenging environments such as wastewater treatment plants, chemical processing facilities, power plants, and oil refineries.

Another benefit of wedge wire intake screens is their versatility. They can be customized to meet specific application requirements, including different slot sizes, open areas, and overall dimensions. This flexibility allows for optimal filtration efficiency and compatibility with a wide range of liquids, including water, oil, chemicals, and industrial fluids.

passive intake screens

Passive intake screens

Passive intake screens are specialized filtration devices used in water intake systems to prevent debris, organisms, and other unwanted particles

from entering and potentially damaging pumps, turbines, or other equipment. Unlike active intake systems that rely on mechanical or electrical components to create flow, its utilize natural water flow to filter out contaminants.

Screens are typically designed with a grid or mesh structure made of durable materials such as stainless steel or reinforced plastics. The mesh size can be customized to suit the specific application, allowing the intake screen to capture larger debris while allowing water to pass through.

The installation of passive intake screens is relatively simple and cost-effective compared to active intake systems. They can be positioned directly in the water source, such as rivers, lakes, or oceans, without the need for complex infrastructure or energy consumption. Maintenance typically involves periodic cleaning to remove accumulated debris from the screen.

Water intake screen

Water intake screen is a vital component in water intake systems, designed to filter and prevent debris, sediment, aquatic organisms,

and other unwanted particles from entering the water supply infrastructure. These screens are crucial for protecting pumps, turbines, and other equipment from damage and maintaining the overall efficiency and reliability of water intake processes.

The construction of water intake screens is critical to their filtration effectiveness. They are commonly made of durable materials like stainless steel, which offers excellent corrosion resistance, mechanical strength, and longevity. The screens are designed with precision to allow water to pass through while capturing and retaining undesirable particles.

The screen design can vary based on the specific requirements of the application. Common types of water intake screens include bar screens, wedge wire screens, and perforated plate screens. Bar screens consist of parallel bars or rods spaced at regular intervals, allowing water to pass through while blocking larger debris. Wedge wire screens feature V-shaped wires and support rods, providing precise filtration by capturing particles in the narrow gaps between the wires. Perforated plate screens have holes of various sizes to allow water to flow while preventing larger particles from entering.

What is the slot size between the wedge wire intake screen?

Custom wedge wire intake screen

The slot size between the wedge wire intake screen can vary widely depending on the specific design and application requirements. Wedge wire intake screens are often customized to meet the needs of different industries and water sources. The slot size typically ranges from as small as a fraction of 50 micrometers (µm) to 3 millimeters (mm) or more. To determine the appropriate slot size for a wedge wire intake screen, it is essential to consider the specific needs of your application.

Is there a minimum approach velocity required for the intake screen to effectively prevent debris entry?

wedge wire intake screen production process

Yes, there is typically a minimum approach velocity required for an intake screen to effectively prevent debris entry. The minimum approach velocity is the minimum velocity of the fluid (e.g., water) approaching the intake screen to ensure that debris and particles are effectively screened out and do not pass through the screen.

The specific minimum approach velocity can vary depending on the design and size of the intake screen, as well as the size and type of debris or particles you want to prevent from entering the intake system.

What is the cleaning mechanism for the intake screen?

Material of wedge wire intake screen

Manual Cleaning: In some cases, the intake screen may be manually cleaned by personnel. This can involve physically removing debris or fouling from the screen’s surface using brushes, scrapers, or other tools.

Backwashing: Backwashing involves reversing the flow of water through the intake screen. This can dislodge and flush away accumulated debris and fouling.

Airburst Cleaning: Airburst cleaning systems use compressed air to release a burst of air bubbles through the intake screen. The rapid expansion of air bubbles helps dislodge and lift debris away from the screen surface, allowing it to be carried away by the water flow.

Rotating Brushes: Some intake screens have rotating brushes that continuously clean the screen’s surface as water flows through. These brushes help prevent the buildup of debris and fouling.

Can the intake screen be installed in both vertical and horizontal orientations?

Construction of wedge wire intake screen

Vertical Orientation:

In a vertical orientation, the intake screen is installed with the screen surface facing downward into the water source. This setup is commonly used in applications where water is drawn from below the surface, such as rivers, lakes, or reservoirs.

Horizontal Orientation:

In a horizontal orientation, the intake screen is installed with the screen surface facing the direction of water flow. This setup is often used in applications where water is drawn from sources with a consistent water level, such as open channels or pipes.

Can the intake screen withstand the forces of water currents, waves, and debris impact without damage?

wedge wire intake screen working principle

The ability of an intake screen to withstand the forces of water currents, waves, and debris impact without damage depends on its robust design and construction. These screens are typically built using durable materials such as stainless steel or reinforced plastics, and their structural integrity is carefully engineered to resist external forces.

Furthermore, the screen’s slot size and open area are carefully designed to balance debris prevention with resistance to clogging and damage from debris impact. Regular inspections and maintenance routines are crucial to identify any wear and tear, ensuring continued performance.

By addressing these factors, intake screens can effectively safeguard water intake systems against damage caused by water forces, waves, and debris impact while maintaining their vital role in preventing unwanted contaminants from entering critical infrastructure.
