Especially suitable for oily sludge-like impurity liquid, water and low viscosity liquid(≤40cps) impurity amount (30pp) It has the characteristics of self-cleaning filter. It integrates multiple slot-type filter elements inside, which enables 24-hour uninterrupted online filtration.When the filter element is blocked, the equipment automatically recognizes and cleans the filter elements one by one through the rotation of the rotatingarm. The single machine has a large filtration area, which can be used for fine filtration at a low surface flow rate. The maximum flow rate of a single machine can reach 800m3/h.Extremely high reliability, it can be used for poor water quality.Accuracy range 20-2000 microns, inlet and outlet sizes 2"-24". Equipped with ACCS series automatic cleaning control system, which integrates the parallel control functions of differential pressure control and time control, which can control the filter to operate efficiently according to the working conditions.
Jeri marine manufactures the most effective, accurate, and dependable auto backwash filters for marine with high quality and economical cost. It can realize fully automatic operation, replacing manual supervision of marine engine room.

Working principle:
Filter:
The liquid flows in from the inlet at the bottom of the filter, flows in from the lower end of the filter element, and flows out through the inner surface of the filter element at the outlet. The particulate impurities are intercepted and accumulated in the filter element, and the pressure difference between the inlet and outlet gradually increases, indicating that the impurities reach a certain thickness, and the filter element flux gradually decreases.
Cleaning:
When the set pressure difference or time is reached, the self-cleaning action starts, the geared motor drives the backwashing arm to align with a filter
element, the upper end of the filter element is sealed, the lower end is connected to the cleaning nozzle, the backwash valve is opened, and the filter
element is The filter element is connected to the sewage pipe, and the pressure difference between the outside of the filter element and the sewage outlet drives the filtrated clear liquid to reversely flush the impurities on the inner surface of the filter element and discharge it into the sewage pipe.After the backwashing of one filter element is completed, close the backwashing valve, and align the cleaning arm to the next filter element for backwashing. After all the filter elements are backwashed one by one, the whole backwashing process is completed.
Sewage:
A positioning plate and a cleaning arm are installed on the drive shaft of the gear motor. The distribution of each positioning hole on the positioning plate corresponds exactly to each filter element. The cleaning arm is positioned corresponding to one of the holes. When the positioning hole reaches the induction channel of the positioning sensor, The output signal of the positioning sensor makes the motor stop rotating, the cleaning arm is aligned with a filter element, the backwash valve is opened for a few seconds and then closed, the cleaning is completed, the motor continues to run, the next positioning hole turns the positioning sensor on again, and the motor is stopped after cleaning. A filter element.
