The use and principle of stainless steel filter
Release Time:2020-08-28  Browse: times
The purpose and principle of stainless steel filter:
When the stainless steel filter works, the water to be filtered enters from the nozzle, flows through the filter screen, and enters the pipeline required by the user through the outlet for process circulation. The particles in the water are trapped inside the filter screen. With such a continuous cycle, more and more particles are intercepted, and the filtering speed becomes slower and slower, while the imported sewage is still continuously entering, and the filter holes will become smaller and smaller, thereby creating pressure between the inlet and the outlet. When the large difference reaches the set value, the differential pressure transmitter transmits the electric signal to the controller, and controls the cry to start the drive motor to drive the shaft to rotate through the transmission assembly. At the same time, the sewage outlet is opened and discharged from the sewage outlet. After the net is cleaned, the pressure difference drops to the minimum, the system returns to the initial filtering state, and the system operates normally.

Installation and use of stainless steel filter:
This type of valve should generally be installed horizontally in the pipeline.
When installing and using, pay attention to the protection of the control box, sensors and transmission parts to prevent damage
Connect the pipe in the direction indicated by the arrow on the body of the stainless steel self-cleaning filter
When adjusting the electric part, please pay attention to the direction of rotation of the motor to be consistent with the direction of the mark
During installation, it should be considered to facilitate maintenance, and bypass pipes should be installed.
When installing, try to consider that the sewage outlet is at the bottom to facilitate the discharge of debris.
The sewage pipe is connected to the sewage ditch, and the sewage pipe should not be too long.

Working principle of stainless steel filter:
The stainless steel filter element uses a high-strength wedge-shaped filter screen, which is automatically cleaned by pressure difference control and timing control. When impurities in the filter accumulate on the surface of the filter element to cause the inlet and outlet pressure difference to increase to the set value, or the timer reaches the preset time, the electric control box sends a signal to drive the backwash mechanism. When the backwash suction cup port is directly opposite to the filter element inlet, the drain valve is opened, and the system discharges pressure at this time. A negative pressure area appears on the inside of the suction cup and the filter element whose relative pressure is lower than the water pressure outside the filter element, forcing part of the net circulating water from the outside of the filter element Flowing into the inside of the filter element, the impurity particles adsorbed on the inner wall of the filter element flow into the drum with water and are discharged from the drain valve. The specially designed filter screen produces a spray effect inside the filter element, and any impurities will be washed away from the smooth inner wall. When the pressure difference between the inlet and outlet of the filter returns to normal or the timer set time ends, the material flows continuously during the whole process, and the backwashing consumes less water, realizing continuous and automated production.
