The working principle of the filter

Sep 07,2024


The working principle of the filter is as follows: When the filter is in operation, the water to be filtered enters through the nozzle, flows through the filter screen, and then enters the pipeline required by the user through the outlet used for the process cycle. The particulate impurities in the water are intercepted by the filter screen. With this continuous cycle, more and more particles are intercepted and the filtration speed becomes slower and slower.

The imported sewage is still constantly flowing in, and the filter holes will become smaller and smaller, resulting in a pressure difference between the inlet and the outlet. When the difference reaches the set value, the differential pressure transmitter sends an electrical signal to the controller. The control system starts the drive motor. The drive shaft rotates through the transmission components, and at the same time, the sewage outlet is opened and discharged from the sewage outlet.

When the filter is cleaned, the pressure difference drops to the minimum and the system returns to the initial shape of the filter. The system is operating normally. This filter is composed of a housing, multiple filtering elements, a backwashing mechanism and a differential pressure controller. The diaphragm inside the shell divides the inner cavity into upper and lower chambers. The upper chamber is equipped with multiple filter elements, which fully fill the filtration space and significantly reduce the volume of the filter. The lower chamber is equipped with backwash suction cups.

Understanding Cyclone Separators: A Key Component in Industrial Filtration Systems

Cyclone separators, also known as cyclone dust collectors, utilize centrifugal force to separate particulate matter from process streams. The design of a cyclone separator typically features a cylindrical body with an inlet where the mixture of air and solids enters at a tangential angle. This design generates a rotating flow pattern that enhances the separation process. When the mixture enters th
