Selection of circulating water filters

Date: 2019-12-31

The circulating water filter is a filter that directly blocks impurities in the water, removes suspended matter and particles in the water body, reduces turbidity, purifies water quality, reduces system dust, bacteria, algae, rust, etc. From the water inlet to the self-cleaning filter body, due to intelligent (PLC, PAC) planning, the system can automatically identify the degree of impurity deposition and automatically discharge the sewage valve signal.

Next we are going to introduce to us the matters needing attention in the selection of circulating water filters.

(1) Generally in the cooling circulating water, since the water is circulated, the side filtration method is generally used, so that not only the filtering effect is better, but the cost performance can be greatly reflected.

(2) ARKAL is an Israeli filter, not an Argentine. They are mainly manufacturers of laminated filters. The filtration accuracy is 55 micrometers, which is generally 100 micrometers.

Then it is not enough to understand the above knowledge points. You also need to know about the principle of the circulating water filter.

The water to be processed by the filter enters the body through the water inlet, and impurities in the water are deposited on the stainless steel filter screen, thereby generating a pressure difference. The pressure difference switch monitors the pressure difference between the water inlet and outlet. When the pressure difference reaches the set value, the electric controller feeds the hydraulic control valve and drives the motor signal. After the equipment is installed, the technicians debug it, set the filtering time and the cleaning conversion time, the water to be treated enters the body from the water inlet, and the filter starts normally. When the preset cleaning time is reached, the electric control water supply control valve, Drive the motor signal to trigger the following actions: The motor drives the brush to rotate to clean the filter element, and at the same time, the control valve opens to drain. The entire cleaning process only needs to continue for dozens of seconds. When the cleaning is completed, the control valve is closed, the motor stops rotating, He recovered to his original condition and started to the next filtering process. The inside of the filter housing is mainly composed of a coarse filter, a fine filter, a suction pipe, a stainless steel brush or a stainless steel suction nozzle, a seal ring, an anticorrosive coating, a rotating shaft, and the like.
