In winter in the process of filtration, fine thin film distillation mesh lining material gradually accumulation, it will form a pressure difference on both sides of inside and outside. When the differential pressure reaches the preset value, the will start automatic cleaning process: drain valve is opened, the head of the component of hydraulic motor and hydraulic cylinder to release pressure and water; Hydraulic motor chamber and the pressure in the suction dirt fell sharply, because the negative pressure effect, through the suction nozzle drain wiped film evaporator contamination of fine mesh lining, the hydraulic motor room by hydraulic motor, through the drain valve, forming a pollution process. When the water flow by the hydraulic motor, drive soak pipe rotation, driven by the hydraulic cylinder piston pollution tube axial movement, pollution components through the combination of axial movement and rotation motion completely clean the whole surface of a mesh inside. The cleaning process will continue for several seconds. Close drain valve at the end of the washing, increase water pressure can make the hydraulic cylinder piston back to its initial position, winterization filter washing cycle began to prepare for the next. In the process of cleaning, winterization filter filter work uninterrupted normal winter.
Principle: backwash automatically on said earlier, backwash by hydraulic valves to open and the action of the hydraulic cylinder piston, which are by backwash controller to control. Back flush controller based on from the wiped film distillation inlet and outlet of the winterization filter can accurately control the differential value of hydraulic valve and hydraulic cylinder, and the controller's power comes from the pressure pipeline itself. CS separator through multistage separation can greatly improve the efficiency of separation, as well as * * preliminary separation processing. Low cost and high reliability by CS first separator preprocessing, and then using the cleaning filter, bag filter, winter winter core type filter of equal precision in winter, winter can obtain a better filtering effect, winter filter material consumption and material consumption were reduced emissions, Shanghai long cheng company provide whole winter filtering solution.
