How to Choose a Circulating Water Filtration Equipment Manufacturer?
Selecting a suitable manufacturer requires evaluating several technical factors.
1. Filtration Accuracy
The filtration accuracy determines the size of particles that can be removed. Before selecting equipment, consider:
- Particle size
- Water quality condition
- Protection requirements
- Downstream equipment sensitivity
A suitable filter rating helps maintain stable system operation.
2. Material Selection
Material selection affects equipment compatibility with the working environment. Common materials include:
- Stainless steel
- Carbon steel
- Special alloy materials
For circulating water systems, stainless steel structures are commonly selected when corrosion resistance and long-term operation are required.
3. Cleaning Method
Automatic cleaning equipment can use different cleaning structures:
Scraper Cleaning: A scraper removes particles from the filter surface through mechanical movement.
Brush Cleaning: A rotating brush removes accumulated contaminants.
Backwashing: Reverse flow removes particles from the filter element.
The suitable cleaning method depends on particle characteristics and system requirements.
4. Control System Configuration
Automatic filtration equipment may include:
- Pressure difference sensors
- PLC controllers
- Automatic valves
- Operation displays
The control system manages cleaning cycles according to preset conditions.
Industry Knowledge: Why Are Self-Cleaning Filters Used in Circulating Water Systems?
Circulating water systems operate continuously, and suspended solids may enter the pipeline through external contamination, corrosion products, or process residues.
Without effective filtration, particles may accumulate in:
- Pumps
- Heat exchangers
- Pipelines
- Valves
Automatic cleaning filtration equipment removes these contaminants while reducing the need for frequent manual maintenance.
The working process usually includes:
- Water enters the filter chamber
- Particles are retained by the filter screen
- Pressure difference increases as contaminants accumulate
- Cleaning mechanism starts automatically
- Removed particles are discharged
This process helps maintain water circulation efficiency.
Key Parameters to Check Before Purchasing
,Flow Rate
The equipment capacity should match the circulating water flow. Important information includes:
- Normal operating flow
- Maximum flow
- Pipeline size
Operating Pressure
Pressure requirements affect equipment structure and component selection. Check:
- System working pressure
- Pressure fluctuation
- Safety requirements
Filtration Rating
Select the appropriate mesh size according to particle removal requirements.
Installation Space
Consider:
- Equipment dimensions
- Pipeline arrangement
- Maintenance access
FAQ
1. What is a circulating water self-cleaning filter?
