About the working principle of Filter equipment
The water enters the filter from the water inlet, first passes through the coarse filter element assembly to filter out larger particles of impurities, and then reaches the fine filter screen. After the fine particles are filtered out through the fine filter screen, the clean water is discharged from the water outlet.
Do you know the working principle of filter equipment? Let's take a look at it briefly!
The water enters the filter from the water inlet, first passes through the coarse filter element assembly to filter out larger particles of impurities, and then reaches the fine filter screen. After the fine particles are filtered out through the fine filter screen, the clean water is discharged from the water outlet. During the filtering process, impurities in the inner layer of the fine filter gradually accumulate, and a pressure difference is formed on both sides of the fine filter. When the pressure difference reaches the preset value, the automatic cleaning process will start: the drain valve opens, the hydraulic motor chamber and hydraulic cylinder of the main assembly release the pressure and discharge the water; the pressure in the hydraulic motor chamber and the sewage suction pipe drops significantly, due to the negative pressure With pressure, the dirt on the inner wall of the fine filter screen is sucked by the suction nozzle, and the dirt flows into the hydraulic motor chamber by the hydraulic motor, and is discharged by the sewage valve to form a dirt suction process. When water flows through the hydraulic motor, it drives the sewage suction pipe to rotate. The hydraulic cylinder piston drives the sewage suction pipe to move axially. The sewage suction assembly cleans the entire inner surface of the filter screen completely through the combination of axial movement and rotation. The entire cleaning process will last for tens of seconds. The drain valve is closed at the end of the cleaning. The increased water pressure will cause the piston of the hydraulic cylinder to return to its initial position, and the filter will begin to prepare for the next flushing cycle. During the cleaning process, the normal filtering work of the filter is uninterrupted.
In summary, it is a brief introduction to the relevant knowledge about the working principle of Filter equipment.
