自清洗过滤器是一种利用滤网拦截水中杂质并自动清洗排污的精密设备，广泛应用于工业、农业、市政等领域的水处理系统。
一、核心原理与功能
1、工作原理
水流通过滤网时，杂质被截留形成压差，当压差达到预设值（通常0.01-0.10Mpa）时，系统自动启动清洗程序，通过反冲洗或机械刮刷清除滤网污物，排污时不断流。
反冲洗式：利用水力或电机驱动吸嘴吸附滤网内壁杂质。
刷式：通过旋转不锈钢刷清洁滤网表面。
2、过滤性能
精度范围：10-3000微米，可适配不同水质需求。
流量范围：单台4-4160m³/h，支持多台并联扩展。
工作压力：0.1-1.6Mpa（部分型号可达2.5Mpa。
二、技术优势
自动化控制：支持压差、时间及手动三种清洗模式，配备PLC/PAC智能系统，可远程监控。
高效清洗：排污时间少，水量损失小。
耐用性：采用316L不锈钢滤网及防腐材质，寿命长且耐腐蚀。
三、应用场景
工业领域：冶金循环水、电力冷却水、化工流程过滤等。
市政与农业：灌溉系统、饮用水预处理、中水回用。
特殊需求：食品医药行业需符合NSF/ANSI 61标准，采用无毒防腐设计。
Self cleaning filter is a precision equipment that uses a filter screen to intercept impurities in water and automatically clean and discharge pollutants. It is widely used in water treatment systems in industrial, agricultural, municipal and other fields.
一、 Core principles and functions
1. Working principle
When the water flows through the filter screen, impurities are trapped and form a pressure difference. When the pressure difference reaches the preset value (usually 0.01-0.10Mpa), the system automatically starts the cleaning program to remove the dirt from the filter screen through backwashing or mechanical scraping, and the discharge does not stop.
Backwash type: using hydraulic or motor-driven suction nozzles to adsorb impurities on the inner wall of the filter screen.
Brush type: Clean the surface of the filter screen by rotating the stainless steel brush.
2. Filtering performance
Accuracy range: 10-3000 microns, adaptable to different water quality requirements.
Flow range: single unit 4-4160m ³/h, supporting parallel expansion of multiple units.
Work pressure: 0.1-1.6Mpa (some models can reach 2.5Mpa).
二、 Technical advantages
Automated control: supports three cleaning modes: differential pressure, time, and manual, equipped with PLC/PAC intelligent system, and can be remotely monitored.
Efficient cleaning: Less discharge time and less water loss.
Durability: Made of 316L stainless steel filter screen and anti-corrosion material, with long service life and corrosion resistance.
三、 Application scenarios
Industrial sector: metallurgical circulating water, power cooling water, chemical process filtration, etc.
Municipal and agricultural: irrigation systems, pre-treatment of drinking water, and reuse of reclaimed water.
Special requirements: The food and pharmaceutical industry needs to comply with NSF/ANSI 61 standards and adopt non-toxic and anti-corrosion design.
