Rail transit has long been used as public transport in cities. It plays an increasingly important role. Economic developed countries urban traffic development history tells us that only by large passenger traffic system of urban rail transit (metro and light rail), is an effective way to fundamentally improve the urban public traffic

Self-cleaning filter to overcome the traditional filtering products, quantity is small, vulnerable to contamination jams, filtering, part of the need to remove the cleaning and unable to monitor the state of the filter and so on shortcomings, with the raw water filter and the function of the automatic filter for cleaning pollution.
The filter adopts high - strength wedge-shaped strainer to control the automatic cleaning of filter element through pressure differential control. When the impurity accumulates in the filter surface causes the import and export pressure difference to increase to the set value, or the timer reaches the preset time, the electric control box sends out the signal to drive the anti-flushing mechanism. When backwash suction dish and filter imports are pair, the drain valve is opened, the system pressure drainage, chuck and filter the inside a relative pressure below the filter of the lateral pressure of negative pressure zone, forcing some net circulating water from the inside filter lateral flow filter, adsorption on the inner wall of the filter in the impurity particles with flow into ç©£ disc and is discharged from the drain valve. The specially designed filter causes the inside of the filter to produce a jet effect, and any impurities will be washed away from the smooth inner wall. When the pressure difference of the filter is returned to normal or the timer set time is finished, the material does not break the flow during the whole process, and the anti-washing water consumption is low, which realizes the continuous and automatic production
