Application and principle of stainless steel Strainer

When the stainless steel Strainer works, the water to be Strainered enters from the water inlet, flows through the Strainer screen, and enters the pipeline required by the user through the outlet for process circulation. The particle acrobatics in the water is intercepted inside the Strainer screen. With such continuous circulation, more and more particles are intercepted and the filtration speed is slower and slower, while the imported sewage still enters continuously, and the Strainer hole will be smaller and smaller, resulting in a pressure difference between the inlet and outlet. When the large difference reaches the set value, the differential pressure transmitter transmits an electrical signal to the controller to control the crying and start the driving 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, When the Strainer screen is cleaned, the differential pressure drops to the minimum, the system returns to the initial filtration state, and the system operates normally.

 

Installation and use of stainless steel Strainer

This kind of valve shall be installed horizontally in the pipeline. During installation and use, pay attention to the protection of control box, sensor and transmission part to prevent damage. Connect the pipe according to the direction indicated by the arrow on the stainless steel self-cleaning Strainer body. When adjusting the electric part, please note that the rotation direction of the motor should be consistent with the identification direction. During installation, it shall be considered to be convenient for maintenance, and the bypass pipe shall be installed. During installation, it shall be considered that the sewage outlet is at the lower part to facilitate the discharge of sundries. The sewage pipe shall be connected to the sewage ditch, and the sewage pipe shall not be too long.

Working principle of stainless steel Strainer

The stainless steel Strainer core adopts high-strength wedge-shaped Strainer screen, which can automatically clean the Strainer element through differential pressure control and timing control. When the impurities in the Strainer accumulate on the surface of the Strainer element, causing the inlet and outlet differential pressure 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 inlet of the backwashing suction cup is aligned with the inlet of the Strainer element, the blowdown valve opens. At this time, the system releases pressure and discharges water. There is a negative pressure area with a relative pressure lower than the water pressure outside the Strainer element inside the suction cup and the Strainer element, forcing part of the net circulating water to flow from the outside of the Strainer element into the inside of the Strainer element. The impurity particles adsorbed on the inner wall of the Strainer element flow into the pan with the water and are discharged from the blowdown valve. The specially designed Strainer screen produces a spraying effect inside the Strainer element, and any impurities will be washed away from the smooth inner wall. When the pressure difference between the inlet and outlet of the Strainer returns to normal or the timer setting time ends, the flow of materials is not cut off in the whole process, and the backwashing water consumption is less, realizing continuous and automatic production.
