DN200 self-cleaning filter is an indispensable treatment method in water purification process, used to intercept various impurities in water, purify water quality or protect the normal operation of other equipment in the system. Ordinary mesh filters are widely used in water source filtration, industrial circulating water systems, and other fields due to their simple structure, good filtration effect, and low resistance. However, their disadvantages are small pollutant holding capacity, susceptibility to blockage by pollutants, and complex cleaning work. The equipment must be disassembled to achieve cleaning of the filtering part, and the status of the filter cannot be monitored. Moreover, they are greatly affected by human factors, resulting in a low degree of automation of the entire system. The fully automatic filter can filter raw water and automatically clean and discharge the filter element, and the system provides uninterrupted water supply during cleaning and discharge. Compared with previous filters, this device has the advantages of high automation, large processing capacity, self-cleaning and sewage discharge, uninterrupted water supply, and wide application range.

Fully automatic self-cleaning filters are widely used in circulating or non circulating cooling water systems, heat exchange systems, central air conditioning systems, central heating systems, hot water boiler systems, etc., to protect cooling equipment, heat exchange devices, air conditioners, boilers, etc. This device is suitable for a wide range of industries, including construction, chemical, power, metallurgy, rubber, paper, textile, coal, food and other industries. The device requires that the water temperature flowing through the filter should not exceed 95 ℃. Water quality requirements for inflow: suspended in the inflow water

If the concentration is less than 150mg/L, it is allowed for the suspended solids to reach 280mg/L in a short period of time. If the water quality does not meet the requirements, pre-treatment should be added before the inlet of the filter.

Fully automatic self-cleaningIt has the function of filtering raw water and automatically cleaning and discharging the filter element, and the system provides uninterrupted water supply during cleaning and discharging. There are two ways to clean a fully automatic filter: automatic control and manual control.

There are two ways of automatic control: timing and pressure difference. Set the filtering time on the filtering timer. When the filtering time is up, start the sewage discharge, and the sewage discharge time is set by the sewage discharge time timer; At the same time, the control system compares the system pressure difference with the user set pressure difference in real time. When the system pressure difference reaches the set pressure difference, the filter also cleans and discharges, and the discharge time is set by the discharge time timer. When the discharge time is up, stop cleaning and restore the system to its initial state, preparing for the next filtration process.
