◆ automatic self-cleaning filters principle (a)

   From the entrance into the water, the coarse filter through the first filter out larger particles of
impurities, and then reach the small screen. In the process of filtering, fine strainer gradually accumulated
water Zangwu, impurity, a filter impurities layer, because of impurities left on the small screen the inside,
so the small screen, the two sides on the formation of a pressure Worse.

   When the filter pressure to default, will begin self-cleaning process, water purification supplies continue
to flow here, cleaning valve open, clean room and sewage-absorption within the substantial decline in water
pressure through the cartridge with the absorption of the sewage pipe Pressure on the poor absorption of
sewage and cleaning rooms between the Xizui produce a suction, forming a suction sewage process. At the
same time, motor driven power absorption sewage pipe along the axial movement to spiral.Suctionsewage
axial movement and rotation of the entire filter, clean the surface completely.The entirewashing
processtakes several seconds. Sewage valve in the washing at the end of the closure. Filter began preparing
for the next wash cycle.

   Pending the entry points into the water from the body, the impurities in the water deposited on the stainless steel strainer, the resulting pressure. Through the pressure switch access points to monitor changes in pressure,
when the pressure to set value, the electric controller to the hydraulic control valve, driving motor signals and trigger the following actions: motor driven rotary brushes, cleaning the filters, control Valve to opensewage,
cleaning the whole process just continued to dozens of seconds, when the cleaning at the end of close control
valves,electrical stop rotation, the system returned to its initial state, began filtering into the next process.

 Equipment installation, commissioning by the technical staff, set the time and filter cleaning conversion time,  pending the entry points into the water from the body, the filter started to work, when to default cleaning time, the electric controller to the hydraulic control valve , Driving motor signals and trigger the following actions: motor driven rotary brushes, cleaning the filters, control valves open to the sewage, cleaning the whole process
just continued to dozens of seconds, when the cleaning at the end of close control valves, electrical stop
Rotation, the system returned to its initial state, began filtering into the next process.

◆ automatic self-cleaning filters principle (c)

Water from the intake into the filter, first of all through rough filter components filtered out larger particles of impurities, and then reach the small screen, filtered through fine strainer small particles of impurities, the water discharged from the outlet. In filtering process, the lining of the small filter impurities gradually piled up on both sides of its internal and external pressure on the formation of a. When the pressure reached default,
will begin self-cleaning process: open sewage valve, in charge of the hydraulic components and hydraulic
cylinder motor room and the release of pressure from the water; hydraulic motors room and a sewage pipe
suction pressure dropped significantly because of Negative role, through fine strainer Xizui absorb the dirt wall by the hydraulic motors into the hydraulic motor room, from the sewage discharge valve, forming a suction
sewage process. When the flow of hydraulic motors, lead pollution suction tube rotation, the hydraulic cylinder
piston driven by the suction pipe for sewage axial movement, absorption through the sewage components
axial movement and rotation of the entire filter, clean the surface completely . Cleaning the whole process will
last tens. Sewage cleaning at the end of the valve closed, the water pressure will increase the hydraulic cylinder piston back to its initial position, filters, began preparing for the next wash cycle. In the washing process, the filter normal filters work uninterrupted.
